Normal FTP servers tend to always want to run with root privileges on the server host. MUDDLEFTPD is designed to overcome this obstacle without limiting the available features when running without root privileges. This manual describes version 1.1 of the program.  File: muddleftpd.info, Node: Invocation, Next: Site Configuration, Prev: Introduction, Up: Top Invocation ********** Neither the server program, MUDDLEFTPD, or the special information program, FTPWHO takes any special arguments except the name of the configuration file to use. If no configuration file is specified on the command line, both programs will try to open the default configuration file.  File: muddleftpd.info, Node: Site Configuration, Next: Troubleshooting, Prev: Invocation, Up: Top Site Configuration ****************** MUDDLEFTPD uses two different configuration files. The main configuration file and the user configuration files. They both use a simple format where lines consist of two items separated by space (key and value). There can only be one pair of key and value on each line. Comments start with the `#' character and continue until the end of the line. Values can include spaces by escaping them with the `\' character as is shown in the example below. # The \ allows space to be recognized as part of the value access /etc/name\ spaced * Menu: * Main config:: Main configuration file * User config:: User configuration files  File: muddleftpd.info, Node: Main config, Next: User config, Up: Site Configuration Main config *********** The main config file is read when muddleftpd is first started. It contains information that applies to the entire program. Some options can be declared several times in the configuration file to add more values. * Menu: * ftpport:: Specify a port to bind to * maxusers:: Maximum user count * logstrength:: The messages to send to main log * runasuid:: The uid to run as * runasgid:: The gid to run as * logfile:: The name of the log file * accessdir:: Directory for user configuration files * timeout:: Default timeout value * addhost:: Allow access to a range of IP numbers * logindump:: File that gets printed when a user connects * pidfile:: File that will store muddleftpds pid number * email:: Email address of the ftp archive maintainer  File: muddleftpd.info, Node: ftpport, Next: maxusers, Up: Main config ftpport ******* * Accepted value: (port)/(ip) | (port) * Default: none `ftpport' tells the server that it should try to listen on `port' for connections. You may specify this directive more than once to listen on more than on port. For each `ftpport' directive, you may also specify the IP number of the interface on which MUDDLEFTPD should accept connections. MUDDLEFTPD will refuse to start if you don't specify atleast one `ftpport' directive. Examples: ftpport 21 #listen to port 21 for connections ftpport 121/127.0.0.1 #listen to port 121 only on the loopback #device ftpport 4990/10.1.1.1 #listen to port 4990 only on the ethernet #device with IP 10.1.1.1  File: muddleftpd.info, Node: maxusers, Next: logstrength, Prev: ftpport, Up: Main config maxusers ******** * Accepted value: (maximum user count) * Default: 30 `maxusers' tells the server the maximum number of users that MUDDLEFTPD will allow to connect at any one time. When the maximum number of users have been reached, all subsequent connections will be silently dropped to prevent resource wastage. If you are setting up an anonymous FTP server, you should have maxusers higher that anonymous's maxusers. This way, a full FTP server doesn't rudely drop connections.  File: muddleftpd.info, Node: logstrength, Next: runasuid, Prev: maxusers, Up: Main config logstrength *********** * Accepted value: (logvalue) * Default: 1 `logstrength' tells the server what information to log. The value for this option is the sum of any of the following types: 1 Clients that try to access the server from invalid ip addresses 2 File transfers, uploads and downloads. 4 Commands the user sends to the server. 8 The replies the server sends to the user. 16 General Information logs (server starting and stopping) 32 Login information, including successful and denied logins. Examples: logstrength 63 # log everything logstrength 0 # log nothing logstrength 51 # log everything except user commands # and server replies  File: muddleftpd.info, Node: runasuid, Next: runasgid, Prev: logstrength, Up: Main config runasuid ******** * Accepted value: (uid) * Default: (none) When setting the directive, the server will attempt to change the user id to `uid'. This is usually used to bind to a privileged port number before switching to another user for user access. This may break some pedantic clients or firewalls, but these are few and far between. If you don't specify this directive, then the server will run with whatever permissions it has when it starts. Examples: runasuid 65535 # run as nobody  File: muddleftpd.info, Node: runasgid, Next: logfile, Prev: runasuid, Up: Main config runasgid ******** * Accepted value: (gid) * Default: (none) When setting the directive, the server will attempt to change the user group id to `uid'. This is usually used to bind to a privileged port number before switching to another user for user access. This may break some pedantic clients or firewalls, but these are few and far between. If you don't specify this directive, then the server will run with whatever permissions it has when it starts. Examples: runasgid 65535 # run as the group nogroup  File: muddleftpd.info, Node: logfile, Next: accessdir, Prev: runasgid, Up: Main config logfile ******* * Accepted value: (filename) * Default: `/var/log/muddleftpd.log' This directive tells MUDDLEFTPD where to store its log file. The server will append to the specified file. This file must exist and be writable to the starting user, otherwise MUDDLEFTPD will refuse to start and exit. Examples: logfile /home/rugger/ftpd/ftpd.log # store logs in an alternative # place  File: muddleftpd.info, Node: accessdir, Next: timeout, Prev: logfile, Up: Main config accessdir ********* * Accepted value: (directory) * Default: `/usr/local/etc' `accessdir' tells MUDDLEFTPD where to find the configuration files describing user access to the server. It must be readable to the running user or MUDDLEFTPD will be unable to autenticate any users. Examples: accessdir /etc/muddleftpd # files are stored in /etc/muddleftpd accessdir /home/rugger/ftpd # files are stored in # /home/rugger/ftpd  File: muddleftpd.info, Node: timeout, Next: addhost, Prev: accessdir, Up: Main config timeout ******* * Accepted value: (seconds) * Default: 300 seconds `timeout' gives the default timeout for a user connection. This timeout will apply before the user logs in, and will persist if timeout isn't configured in the user configuration files. Examples: timeout 20 # users must log in within 20 seconds timeout 3600 # 1 hour timeout  File: muddleftpd.info, Node: addhost, Next: logindump, Prev: timeout, Up: Main config addhost ******* * Accepted value: (ip address)/(netmask) * Default: (none) `addhost' tells the server to allow access to a given subnet. By default, MUDDLEFTPD denies access to all hosts. Examples: addhost 192.203.224.0/255.255.255.0 # allow access to all hosts from 192.203.224.X addhost 76.2.0.0/255.255.0.0 # allow access to all hosts from 76.2.X.X addhost 10.2.9.34/255.255.255.255 # allow access to host 10.2.9.34 addhost 0.0.0.0/0.0.0.0 # allow access to everyone  File: muddleftpd.info, Node: logindump, Next: pidfile, Prev: addhost, Up: Main config logindump ********* * Accepted value: (filename) * Default: (none) `logindump' specifies what file will be displayed to the user before the user logs in. All normal magic cookies are available (except %C) for use, although the information in many of them is useless until the user logs in. *Note Magic Cookies::. This can be used to display welcome messages and information to the user before he or she logs in. Examples: logindump /etc/issue # display the issue file logindump /etc/issue.ftp # display this file  File: muddleftpd.info, Node: pidfile, Next: email, Prev: logindump, Up: Main config pidfile ******* * Accepted value: (filename) * Default: `/var/run/muddleftpd.pid' `pidfile' defines the file that you wish to store the pid of the main MUDDLEFTPD process in. It is required to determine if MUDDLEFTPD is already running with a particular config file. If one can not be created, the server will abort and refuse to run. `pidfile' MUST not be in a directory where other users can create links. Examples: pidfile /home/rugger/pids/muddleftpd.pid # store the pid file here  File: muddleftpd.info, Node: email, Prev: pidfile, Up: Main config email ***** * Accepted value: (email address) * Default: `' `email' is where you provide an email address that is stored in the magic cookie %E. *Note Magic Cookies::. You can specify anything you want. Examples: email ekuiperba@cc.curtin.edu.au email I\ don't\ want\ to\ tell\ you! # just a string  File: muddleftpd.info, Node: User config, Prev: Main config, Up: Site Configuration User config *********** The user configuration files define almost everything about a user connection to the ftp server. This includes home directory, root directory, password and file access rights. MUDDLEFTPD will have at least one ofthese files, and will load them in the following order: 1. `user.' 2. `user.default' `user.default' will be loaded if MUDDLEFTPD can not find the first configuration file. Note that if `user.default' doesn't exist, then an error message will be written to the log. You can also create `group.' files that can be used as templates for `user.' files. If you specify a group template file in the `user.' file, then the `group.' file will be loaded AFTER the `user.' file has been parsed. If you specify a directive more than once in a user config file, then the first one will be the one that the server recognizes. User files also use magic cookies to improve configurablity. *Note Magic Cookies::. * Menu: * group:: Specify what group template file to use * password:: Set the user's encrypted password * rootdir:: Set the user's root directory * homedir:: Set the user's home directory * welcome:: Set what file is dumped when the user logs in * access:: Add an entry to the ACL table * umask:: Set the default umask for all created files * unixuser:: Set the username to read magic tokens from * maxconnect:: Set the maximum number of times this user can connect * utimeout:: Set this users timeout * permissions:: Set the uid and/or gid this user will access files as * dumpfiles:: Dump files for various events and actions * chmoding:: Set ability to change umask and file permissions  File: muddleftpd.info, Node: group, Next: password, Up: User config group ***** * Accepted value: (group name) * Default: (none) `group' tells the server to load the file `group.(groupname)' after processing all the directives in the user configuration file. This lets you use templates that multiple user configuration files can use. If this group file doesn't exist, a log entry will be generated. These group files are kept in the same directory as the user config files. Examples: group users # read the file group.users group # use no group file  File: muddleftpd.info, Node: password, Next: rootdir, Prev: group, Up: User config password ******** * Accpted value: (encrypted password) * Default: `%p' `password' specifies the password (in encrypted form) that the user must enter to successfully log on. If you specify `*', the username is disabled. if you specify `', then any password is accepted. Examples: password %p # use the normal password from /etc/passwd password %s # use a shadow password. password # accept any password.  File: muddleftpd.info, Node: rootdir, Next: homedir, Prev: password, Up: User config rootdir ******* * Accepted value: (directory) * Default: `/' `rootdir' specifies the root directory for this user. The user will not be able to access directories above this directory (unless a symbolic link exists to an outside directory, where that directory and its children will be visible). Examples: rootdir %h # use the home directory as the root directory. rootdir /home/ftp # use /home/ftp as the root directory. rootdir / # use / as the root directory.  File: muddleftpd.info, Node: homedir, Next: welcome, Prev: rootdir, Up: User config homedir ******* * Accepted value: (directory) * Default: `%h' `homedir' is the directory the server will place a user in after they have been successfully authenticated. It is relative to `rootdir' (eg if `homedir' is `/cow' and `rootdir' is `/mad', then the login directory will be `/mad/cow'). The user can also use `~' to access their home directory. Examples: homedir %h # set home directory to the passwd home directory homedir / # use / as the home directory.  File: muddleftpd.info, Node: welcome, Next: access, Prev: homedir, Up: User config welcome ******* * Accepted value: (filename) * Default: (none) `welcome' specifies the file that the user will see when he or she logs in. It is an absolute filename (no relation to rootdir). File magic cookies apply to this file. *Note Magic Cookies::. Examples: welcome /etc/ftpwelcome welcome /home/ftp/welcome.txt  File: muddleftpd.info, Node: access, Next: umask, Prev: welcome, Up: User config access ****** * Accepted value: (filename or directory):(keys) * Default: no access. `access' controls the ACL access layer that MUDDLEFTPD places above unix file system permissions. (filename or directory) specify the filename or directory to which these restrictions apply. (keys) specify which access rights to grant to the user in this directory or file. (filename or directory) is relative to rootdir. If a filename is specified, then the access will apply only to that file. If a directory is specified by ending (filename or directory) with a `/', then the access directive will apply to all files and subdirectories of that directory. The default is to give no access. To allow unix permission define access, use access /:ALL in the user configuration file. The following keys are available: R Read file or directory L List files (only meaningful for directories) A Add new files (only meaningful for directories) W Write access. D Delete file access (only meaningful for directories) X Do not override this ACL (if one exists in the group file) ALL All attributes except X NONE No attributes (no access) Examples: access /etc/ftpwelcome:R # give read access to /etc/ftpwelcome access /etc/:R # give read access to all files in /etc/ access /incoming/:A # give add file access to /incoming access /:ALL # give full access to all files, dirs. access /secret/:NONE # don't give access to any files in /secret.  File: muddleftpd.info, Node: umask, Next: unixuser, Prev: access, Up: User config umask ***** * Accepted value: (octal integer) * Default: umask when MUDDLEFTPD was started `umask' specifies what attributes files and directories will be given when they are created. `umask' specifies what bits are not set. Examples: umask 077 # only user bits are set on new file creation umask 666 # all new files are set non-accessible.  File: muddleftpd.info, Node: unixuser, Next: maxconnect, Prev: umask, Up: User config unixuser ******** * Accepted value: (username) * Default: (none) `unixuser' specifies what username to load the magic cookies from. It loads these cookies from the password file (`/etc/passwd') with (username). The only magic cookie available to this directive %U. *Note Magic Cookies::. Examples: unixuser %U # use the entered username as the unix username unixuser ftp # use the user ftp for all the cookies  File: muddleftpd.info, Node: maxconnect, Next: utimeout, Prev: unixuser, Up: User config maxconnect ********** * Accepted value: (count) * Default: (no limit) `maxconnect' controls how many people with the same username can log in at the same time (NOTE: This restribution is per username and not per configuration file). If this value is reached, user trying to connect will be denied access and `busydump' will be returned to the user. Examples: maxconnect 10 maxconnect 150  File: muddleftpd.info, Node: utimeout, Next: permissions, Prev: maxconnect, Up: User config utimeout ******** * Accepted value: (seconds) * Default: the main configuration timeout value This sets the `utimeout' for this specific user. Any sessions will automaticly be disconnected after this period of inactivity. Examples: utimeout 600 # set user timeout to 10 minutes utimeout 7200 # set user timeout to 2 hours.  File: muddleftpd.info, Node: permissions, Next: dumpfiles, Prev: utimeout, Up: User config permissions *********** * Accepted value: (integer) * Default: %u | %g The `uid' and `gid' directives sets the user and group id that all user requests file accesses will be performed as. Note: The server will not accept uid 0 (root) and will automatically change it to -1 (nobody). gid 0 (root or wheel) will be changed to -1 (nogroup). Examples: uid 20 # use user id 20 for all file access. uid %u # use the user id from the password file. gid 20 # use group id 20 for all file access. gid %g # use the group id from the password file.  File: muddleftpd.info, Node: dumpfiles, Next: chmoding, Prev: permissions, Up: User config dumpfiles ********* * Accepted value: (filename) * Default: (none) The `cddump', `busydump' and `quitdump' directives specify what files to send to the user when they perform a number of actions or when a certain event occurs. `cddump' specifies the file to send when a change directory action is performed. `busydump' specifies the file to send when `maxconnect' number of users are already connected. `quitdump' specifies the file to send when the user disconnects from the ftp service. File magic cookies apply to these files. *Note Magic Cookies::. Examples: cddump .message # show .message in the directory the user # changes to. busydump /etc/ftpbusy quitdump /etc/ftpbye  File: muddleftpd.info, Node: chmoding, Prev: dumpfiles, Up: User config chmoding ******** * Accepted value: 0 | 1 * Default: 0 If `chmoding' is set to 1, the user is allowed to change the umask and change permissions on files. Examples: chmoding 0 # disable chmod and umask changing chmoding 1 # enable chmod and umask changing  File: muddleftpd.info, Node: Troubleshooting, Next: FTP Commands, Prev: Site Configuration, Up: Top Troubleshooting *************** If problems occur while compiling, check the following: * If you are running OpenLinux 2.2, make sure that you have downloaded and installed the crypt package. Get it from: If you get either of these messages when running the sever: `muddleftpd error in file init.c line 51: muddleftpd already running!' This means that you are already running a copy of muddleftpd using the configuration file muddleftpd tried to open. (That is, the default compiled in config file, or what you specified on the command line). Simply close down the old version (with a SIGTERM) and start it again. `muddleftpd error in file shmem.c line 91: Permission denied' This means that muddleftpd could not get write permission on the main configuration file (It is used for locking the shared memory). You must give the user running muddleftpd write permission to the main config file muddleftpd will be running as.  File: muddleftpd.info, Node: FTP Commands, Next: Magic Cookies, Prev: Troubleshooting, Up: Top FTP Commands ************ The following commands are understood and used by muddleftpd: PORT Define the data port the server will connect to PASV Tell the server that the next data connection will use passive mode RETR Retreive a file from the server STOR Store a file on the server STOU Store a file on the server using an unique filename APPE Append to a file on the server TYPE Specify what type to transfer data (A = Ascii, B = binary) QUIT Quit the ftp server PASS Password to log on using USER Username to log on using SYST Returns the system type muddleftpd is running on (UNIX) LIST Do a long list over a data connection NLST Do a short list over a data connection PWD see XPWD XPWD Return the current directory CWD see XCWD XCWD Change the working directory ABOR Abort a data connection in progress CDUP Change to the parent directory.

Magic cookies recognized in files are replaced with the values they represent as MUDDLEFTPD parses them. eg: my email is %E has the magic cookie %E. Since %E represents the FTP server maintainer's email address, MUDDLEFTPD would create the following: my email is ekuiperba@cc.curtin.edu.au All magic cookies in MUDDLEFTPD start with a % char. There are 2 formats available: The %x Format: This format is simplest syntax and simply replaces the cookie (%x) with the entire string that represents the character x. The %(m,n)x Format: This format selects a range of characters from the string cookie (%x) represents. m is the first character to insert and n is the last character to insert from cookie x. The first character in a magic cookie is numbered is 0. m and n are both adjusted so m >= 0 and n <= length of the Magic cookie. *Note Magic Cookies::. if n > m, then the cookie is considered invalid, see below. eg. %(0,5)u will give the first six characters of what magic cookie u represents. %(10,10)E returns the 11th character of what cookie E represents. %(6,8)M returns the 7th to 9th characters from what cookie M represents. %(10,8)F This is invalid because n > m. Invalid Syntax: If MUDDLEFTPD determines that a magic cookie is invalid (ie, it doesn't exist or is the format is bad), then the line where the magic cookie was found will not be parsed and an entry (informational) will be added to the log. The following magic cookies are recognized in dumped files: %T The current time in the format: Wed Jan 30 21:49:08 1993 %U The username the user used to login %C The current directory of the user %E The administrators email, set in the main config file %M The maximum number of users muddleftpd will log on at a time %N The current number of users logged into this muddleftpd server. %R The string representation of the remote user's IP (muddleftpd doesn't do reverse name lookup on users) %L The full hostname of the host muddleftpd is running on %f The number of files the user has downloaded %F The number of files the user has uploaded %b The number of bytes the user has downloaded, downloading files. %B The number of bytes the user has uploaded, uploading files %I The number of bytes the user has downloaded, from listings %i The number of listings the user has downloaded %D The total number of bytes downloaded (listing and file downloads) over data connections. %d The total number of connections opened for downloading (listing and file downloads) %t The total number of bytes transfered (listing, uploading and downloading) over data connections %c The total number of data connections made (for listing, uploading and downloading) You can also use the %(m,n)x format on any of the above cookies. (although doing so may not be useful for many of the cookies) The %C magic cookie is invalid during the logindump file, because the user has no current directory before startup. To make user configuration files flexable, a set of magic cookies are accepted in these files. Most of these magic cookies get read from the password file. The following magic cookies are recognized in config files: %U The username of the connecting party %p The encrypted password from the normal password file %s The encrypted password from the shadow password file (if your system uses shadow passwords) %u The uid from the password file %g The gid from the password file %h The home directory from the password file. You can also use the %(m,n)x format on any of the above cookies. (although doing so may not be useful for many of the cookies) For the unixuser directive, only %U will be avaliable. unixuser will load the other cookies thought.

Normal FTP servers tend to always want to run with root privileges on the server host. @sc{muddleftpd} is designed to overcome this obstacle without limiting the available features when running without root privileges. This manual describes version 1.1 of the program. @node Invocation, Site Configuration, Introduction, Top @chapter Invocation Neither the server program, @sc{muddleftpd}, or the special information program, @sc{ftpwho} takes any special arguments except the name of the configuration file to use. If no configuration file is specified on the command line, both programs will try to open the default configuration file. @node Site Configuration, Troubleshooting, Invocation, Top @chapter Site Configuration @sc{muddleftpd} uses two different configuration files. The main configuration file and the user configuration files. They both use a simple format where lines consist of two items separated by space (key and value). There can only be one pair of key and value on each line. Comments start with the @samp{#} character and continue until the end of the line. Values can include spaces by escaping them with the @samp{\} character as is shown in the example below. @example # The \ allows space to be recognized as part of the value access /etc/name\ spaced @end example @menu * Main config:: Main configuration file * User config:: User configuration files @end menu @node Main config, User config, , Site Configuration @chapter Main config The main config file is read when muddleftpd is first started. It contains information that applies to the entire program. Some options can be declared several times in the configuration file to add more values. @menu * ftpport:: Specify a port to bind to * maxusers:: Maximum user count * logstrength:: The messages to send to main log * runasuid:: The uid to run as * runasgid:: The gid to run as * logfile:: The name of the log file * accessdir:: Directory for user configuration files * timeout:: Default timeout value * addhost:: Allow access to a range of IP numbers * logindump:: File that gets printed when a user connects * pidfile:: File that will store muddleftpds pid number * email:: Email address of the ftp archive maintainer @end menu @node ftpport, maxusers, , Main config @chapter ftpport @ciindex ftpport @itemize @bullet @item Accepted value: (port)/(ip) | (port) @item Default: none @end itemize @samp{ftpport} tells the server that it should try to listen on @samp{port} for connections. You may specify this directive more than once to listen on more than on port. For each @samp{ftpport} directive, you may also specify the IP number of the interface on which @sc{muddleftpd} should accept connections. @sc{muddleftpd} will refuse to start if you don't specify atleast one @samp{ftpport} directive. Examples: @example ftpport 21 #listen to port 21 for connections ftpport 121/127.0.0.1 #listen to port 121 only on the loopback #device ftpport 4990/10.1.1.1 #listen to port 4990 only on the ethernet #device with IP 10.1.1.1 @end example @node maxusers, logstrength, ftpport, Main config @chapter maxusers @ciindex maxusers @itemize @bullet @item Accepted value: (maximum user count) @item Default: 30 @end itemize @samp{maxusers} tells the server the maximum number of users that @sc{muddleftpd} will allow to connect at any one time. When the maximum number of users have been reached, all subsequent connections will be silently dropped to prevent resource wastage. If you are setting up an anonymous FTP server, you should have maxusers higher that anonymous's maxusers. This way, a full FTP server doesn't rudely drop connections. @node logstrength, runasuid, maxusers, Main config @chapter logstrength @ciindex logstrength @itemize @bullet @item Accepted value: (logvalue) @item Default: 1 @end itemize @samp{logstrength} tells the server what information to log. The value for this option is the sum of any of the following types: @multitable @columnfractions .10 .9 @item 1 @tab Clients that try to access the server from invalid ip addresses @item 2 @tab File transfers, uploads and downloads. @item 4 @tab Commands the user sends to the server. @item 8 @tab The replies the server sends to the user. @item 16 @tab General Information logs (server starting and stopping) @item 32 @tab Login information, including successful and denied logins. @end multitable Examples: @example logstrength 63 # log everything logstrength 0 # log nothing logstrength 51 # log everything except user commands # and server replies @end example @node runasuid, runasgid, logstrength, Main config @chapter runasuid @ciindex runasuid @itemize @bullet @item Accepted value: (uid) @item Default: (none) @end itemize When setting the directive, the server will attempt to change the user id to @samp{uid}. This is usually used to bind to a privileged port number before switching to another user for user access. This may break some pedantic clients or firewalls, but these are few and far between. If you don't specify this directive, then the server will run with whatever permissions it has when it starts. Examples: @example runasuid 65535 # run as nobody @end example @node runasgid, logfile, runasuid, Main config @chapter runasgid @ciindex runasgid @itemize @bullet @item Accepted value: (gid) @item Default: (none) @end itemize When setting the directive, the server will attempt to change the user group id to @samp{uid}. This is usually used to bind to a privileged port number before switching to another user for user access. This may break some pedantic clients or firewalls, but these are few and far between. If you don't specify this directive, then the server will run with whatever permissions it has when it starts. Examples: @example runasgid 65535 # run as the group nogroup @end example @node logfile, accessdir, runasgid, Main config @chapter logfile @ciindex logfile @itemize @bullet @item Accepted value: (filename) @item Default: @file{/var/log/muddleftpd.log} @end itemize This directive tells @sc{muddleftpd} where to store its log file. The server will append to the specified file. This file must exist and be writable to the starting user, otherwise @sc{muddleftpd} will refuse to start and exit. Examples: @example logfile /home/rugger/ftpd/ftpd.log # store logs in an alternative # place @end example @node accessdir, timeout, logfile, Main config @chapter accessdir @ciindex accessdir @itemize @bullet @item Accepted value: (directory) @item Default: @file{/usr/local/etc} @end itemize @samp{accessdir} tells @sc{muddleftpd} where to find the configuration files describing user access to the server. It must be readable to the running user or @sc{muddleftpd} will be unable to autenticate any users. Examples: @example accessdir /etc/muddleftpd # files are stored in /etc/muddleftpd accessdir /home/rugger/ftpd # files are stored in # /home/rugger/ftpd @end example @node timeout, addhost, accessdir, Main config @chapter timeout @ciindex timeout @itemize @bullet @item Accepted value: (seconds) @item Default: 300 seconds @end itemize @samp{timeout} gives the default timeout for a user connection. This timeout will apply before the user logs in, and will persist if timeout isn't configured in the user configuration files. Examples: @example timeout 20 # users must log in within 20 seconds timeout 3600 # 1 hour timeout @end example @node addhost, logindump, timeout, Main config @chapter addhost @ciindex addhost @itemize @bullet @item Accepted value: (ip address)/(netmask) @item Default: (none) @end itemize @samp{addhost} tells the server to allow access to a given subnet. By default, @sc{muddleftpd} denies access to all hosts. Examples: @example addhost 192.203.224.0/255.255.255.0 # allow access to all hosts from 192.203.224.X addhost 76.2.0.0/255.255.0.0 # allow access to all hosts from 76.2.X.X addhost 10.2.9.34/255.255.255.255 # allow access to host 10.2.9.34 addhost 0.0.0.0/0.0.0.0 # allow access to everyone @end example @node logindump, pidfile, addhost, Main config @chapter logindump @ciindex logindump @itemize @bullet @item Accepted value: (filename) @item Default: (none) @end itemize @samp{logindump} specifies what file will be displayed to the user before the user logs in. All normal magic cookies are available (except %C) for use, although the information in many of them is useless until the user logs in. @xref{Magic Cookies}. This can be used to display welcome messages and information to the user before he or she logs in. Examples: @example logindump /etc/issue # display the issue file logindump /etc/issue.ftp # display this file @end example @node pidfile, email, logindump, Main config @chapter pidfile @ciindex pidfile @itemize @bullet @item Accepted value: (filename) @item Default: @file{/var/run/muddleftpd.pid} @end itemize @samp{pidfile} defines the file that you wish to store the pid of the main @sc{muddleftpd} process in. It is required to determine if @sc{muddleftpd} is already running with a particular config file. If one can not be created, the server will abort and refuse to run. @samp{pidfile} MUST not be in a directory where other users can create links. Examples: @example pidfile /home/rugger/pids/muddleftpd.pid # store the pid file here @end example @node email, , pidfile, Main config @chapter email @ciindex email @itemize @bullet @item Accepted value: (email address) @item Default: @samp{} @end itemize @samp{email} is where you provide an email address that is stored in the magic cookie %E. @xref{Magic Cookies}. You can specify anything you want. Examples: @example email ekuiperba@@cc.curtin.edu.au email I\ don't\ want\ to\ tell\ you! # just a string @end example @node User config, , Main config, Site Configuration @chapter User config The user configuration files define almost everything about a user connection to the ftp server. This includes home directory, root directory, password and file access rights. @sc{muddleftpd} will have at least one ofthese files, and will load them in the following order: @enumerate @item @file{user.} @item @file{user.default} @end enumerate @file{user.default} will be loaded if @sc{muddleftpd} can not find the first configuration file. Note that if @file{user.default} doesn't exist, then an error message will be written to the log. You can also create @file{group.} files that can be used as templates for @file{user.} files. If you specify a group template file in the @file{user.} file, then the @file{group.} file will be loaded AFTER the @file{user.} file has been parsed. If you specify a directive more than once in a user config file, then the first one will be the one that the server recognizes. User files also use magic cookies to improve configurablity. @xref{Magic Cookies}. @menu * group:: Specify what group template file to use * password:: Set the user's encrypted password * rootdir:: Set the user's root directory * homedir:: Set the user's home directory * welcome:: Set what file is dumped when the user logs in * access:: Add an entry to the ACL table * umask:: Set the default umask for all created files * unixuser:: Set the username to read magic tokens from * maxconnect:: Set the maximum number of times this user can connect * utimeout:: Set this users timeout * permissions:: Set the uid and/or gid this user will access files as * dumpfiles:: Dump files for various events and actions * chmoding:: Set ability to change umask and file permissions @end menu @node group, password, , User config @chapter group @ciindex group @itemize @bullet @item Accepted value: (group name) @item Default: (none) @end itemize @samp{group} tells the server to load the file @file{group.(groupname)} after processing all the directives in the user configuration file. This lets you use templates that multiple user configuration files can use. If this group file doesn't exist, a log entry will be generated. These group files are kept in the same directory as the user config files. Examples: @example group users # read the file group.users group # use no group file @end example @node password, rootdir, group, User config @chapter password @ciindex password @itemize @bullet @item Accpted value: (encrypted password) @item Default: @samp{%p} @end itemize @samp{password} specifies the password (in encrypted form) that the user must enter to successfully log on. If you specify @samp{*}, the username is disabled. if you specify @samp{}, then any password is accepted. Examples: @example password %p # use the normal password from /etc/passwd password %s # use a shadow password. password # accept any password. @end example @node rootdir, homedir, password, User config @chapter rootdir @ciindex rootdir @itemize @bullet @item Accepted value: (directory) @item Default: @file{/} @end itemize @samp{rootdir} specifies the root directory for this user. The user will not be able to access directories above this directory (unless a symbolic link exists to an outside directory, where that directory and its children will be visible). Examples: @example rootdir %h # use the home directory as the root directory. rootdir /home/ftp # use /home/ftp as the root directory. rootdir / # use / as the root directory. @end example @node homedir, welcome, rootdir, User config @chapter homedir @ciindex homedir @itemize @bullet @item Accepted value: (directory) @item Default: @samp{%h} @end itemize @samp{homedir} is the directory the server will place a user in after they have been successfully authenticated. It is relative to @samp{rootdir} (eg if @samp{homedir} is @file{/cow} and @samp{rootdir} is @file{/mad}, then the login directory will be @file{/mad/cow}). The user can also use @samp{~} to access their home directory. Examples: @example homedir %h # set home directory to the passwd home directory homedir / # use / as the home directory. @end example @node welcome, access, homedir, User config @chapter welcome @ciindex welcome @itemize @bullet @item Accepted value: (filename) @item Default: (none) @end itemize @samp{welcome} specifies the file that the user will see when he or she logs in. It is an absolute filename (no relation to rootdir). File magic cookies apply to this file. @xref{Magic Cookies}. Examples: @example welcome /etc/ftpwelcome welcome /home/ftp/welcome.txt @end example @node access, umask, welcome, User config @chapter access @ciindex access @itemize @bullet @item Accepted value: (filename or directory):(keys) @item Default: no access. @end itemize @samp{access} controls the ACL access layer that @sc{muddleftpd} places above unix file system permissions. (filename or directory) specify the filename or directory to which these restrictions apply. (keys) specify which access rights to grant to the user in this directory or file. (filename or directory) is relative to rootdir. If a filename is specified, then the access will apply only to that file. If a directory is specified by ending (filename or directory) with a @samp{/}, then the access directive will apply to all files and subdirectories of that directory. The default is to give no access. To allow unix permission define access, use @example access /:ALL @end example in the user configuration file. The following keys are available: @multitable @columnfractions .10 .9 @item R @tab Read file or directory @item L @tab List files (only meaningful for directories) @item A @tab Add new files (only meaningful for directories) @item W @tab Write access. @item D @tab Delete file access (only meaningful for directories) @item X @tab Do not override this ACL (if one exists in the group file) @item @item ALL @tab All attributes except X @item NONE @tab No attributes (no access) @end multitable Examples: @example access /etc/ftpwelcome:R # give read access to /etc/ftpwelcome access /etc/:R # give read access to all files in /etc/ access /incoming/:A # give add file access to /incoming access /:ALL # give full access to all files, dirs. access /secret/:NONE # don't give access to any files in /secret. @end example @node umask, unixuser, access, User config @chapter umask @ciindex umask @itemize @bullet @item Accepted value: (octal integer) @item Default: umask when @sc{muddleftpd} was started @end itemize @samp{umask} specifies what attributes files and directories will be given when they are created. @samp{umask} specifies what bits are not set. Examples: @example umask 077 # only user bits are set on new file creation umask 666 # all new files are set non-accessible. @end example @node unixuser, maxconnect, umask, User config @chapter unixuser @ciindex unixuser @itemize @bullet @item Accepted value: (username) @item Default: (none) @end itemize @samp{unixuser} specifies what username to load the magic cookies from. It loads these cookies from the password file (@file{/etc/passwd}) with (username). The only magic cookie available to this directive %U. @xref{Magic Cookies}. Examples: @example unixuser %U # use the entered username as the unix username unixuser ftp # use the user ftp for all the cookies @end example @node maxconnect, utimeout, unixuser, User config @chapter maxconnect @ciindex maxconnect @itemize @bullet @item Accepted value: (count) @item Default: (no limit) @end itemize @samp{maxconnect} controls how many people with the same username can log in at the same time (NOTE: This restribution is per username and not per configuration file). If this value is reached, user trying to connect will be denied access and @samp{busydump} will be returned to the user. Examples: @example maxconnect 10 maxconnect 150 @end example @node utimeout, permissions, maxconnect, User config @chapter utimeout @ciindex utimeout @itemize @bullet @item Accepted value: (seconds) @item Default: the main configuration timeout value @end itemize This sets the @samp{utimeout} for this specific user. Any sessions will automaticly be disconnected after this period of inactivity. Examples: @example utimeout 600 # set user timeout to 10 minutes utimeout 7200 # set user timeout to 2 hours. @end example @node permissions, dumpfiles, utimeout, User config @chapter permissions @ciindex uid @ciindex gid @itemize @bullet @item Accepted value: (integer) @item Default: %u | %g @end itemize The @samp{uid} and @samp{gid} directives sets the user and group id that all user requests file accesses will be performed as. Note: The server will not accept uid 0 (root) and will automatically change it to -1 (nobody). gid 0 (root or wheel) will be changed to -1 (nogroup). Examples: @example uid 20 # use user id 20 for all file access. uid %u # use the user id from the password file. gid 20 # use group id 20 for all file access. gid %g # use the group id from the password file. @end example @node dumpfiles, chmoding, permissions, User config @chapter dumpfiles @ciindex cddump @ciindex busydump @ciindex quitdump @itemize @bullet @item Accepted value: (filename) @item Default: (none) @end itemize The @samp{cddump}, @samp{busydump} and @samp{quitdump} directives specify what files to send to the user when they perform a number of actions or when a certain event occurs. @samp{cddump} specifies the file to send when a change directory action is performed. @samp{busydump} specifies the file to send when @samp{maxconnect} number of users are already connected. @samp{quitdump} specifies the file to send when the user disconnects from the ftp service. File magic cookies apply to these files. @xref{Magic Cookies}. Examples: @example cddump .message # show .message in the directory the user # changes to. busydump /etc/ftpbusy quitdump /etc/ftpbye @end example @node chmoding, , dumpfiles, User config @chapter chmoding @ciindex chmoding @itemize @bullet @item Accepted value: 0 | 1 @item Default: 0 @end itemize If @samp{chmoding} is set to 1, the user is allowed to change the umask and change permissions on files. Examples: @example chmoding 0 # disable chmod and umask changing chmoding 1 # enable chmod and umask changing @end example @node Troubleshooting, FTP Commands, Site Configuration, Top @chapter Troubleshooting If problems occur while compiling, check the following: @itemize @bullet @item If you are running OpenLinux 2.2, make sure that you have downloaded and installed the crypt package. Get it from: @url{ftp://ftp.linuxland.de/pub/OpenLinux/crypto/2.2/glibc-crypt-2.1-3i.i386.rpm} @end itemize If you get either of these messages when running the sever: @table @samp @item muddleftpd error in file init.c line 51: muddleftpd already running! This means that you are already running a copy of muddleftpd using the configuration file muddleftpd tried to open. (That is, the default compiled in config file, or what you specified on the command line). Simply close down the old version (with a SIGTERM) and start it again. @item muddleftpd error in file shmem.c line 91: Permission denied This means that muddleftpd could not get write permission on the main configuration file (It is used for locking the shared memory). You must give the user running muddleftpd write permission to the main config file muddleftpd will be running as. @end table @node FTP Commands, Magic Cookies, Troubleshooting, Top @chapter FTP Commands The following commands are understood and used by muddleftpd: @multitable @columnfractions .20 .8 @item PORT @tab Define the data port the server will connect to @item PASV @tab Tell the server that the next data connection will use passive mode @item RETR @tab Retreive a file from the server @item STOR @tab Store a file on the server @item STOU @tab Store a file on the server using an unique filename @item APPE @tab Append to a file on the server @item TYPE @tab Specify what type to transfer data (A = Ascii, B = binary) @item QUIT @tab Quit the ftp server @item PASS @tab Password to log on using @item USER @tab Username to log on using @item SYST @tab Returns the system type muddleftpd is running on (UNIX) @item LIST @tab Do a long list over a data connection @item NLST @tab Do a short list over a data connection @item PWD @tab see XPWD @item XPWD @tab Return the current directory @item CWD @tab see XCWD @item XCWD @tab Change the working directory @item ABOR @tab Abort a data connection in progress @item CDUP @tab Change to the parent directory. @item XCUP @tab see CDUP @item STAT @tab return server status or a listing over the control connection. @item NOOP @tab Do nothing @item REIN @tab Reinitalize the server for a new user @item REST @tab Resume a data transfer at a particular position @item DELE @tab Delete a file @item MKD @tab see XMKD @item XMKD @tab make a new directory @item RMD @tab see XRMD @item XRMD @tab remove a directory @item RNFR @tab set the file to rename @item RNTO @tab set the name to rename to @item SIZE @tab get the size of a file using the current TYPE setting @item MDTM @tab get the modification time of a file @item HELP @tab show list of recognized commands @item SITE DUMP @tab display a file over the control connection @item SITE ACCESS @tab show ACLs of the current user @item SITE HELP @tab show recognised site commands @item SITE UMASK @tab set the umask @item SITE CHMOD @tab change the permissions of a file @end multitable Commands recognised but ignored in muddleftpd @multitable @columnfractions .20 .8 @item ALLO @tab Allocate space (not needed) @item ACCT @tab Account name (not needed) @end multitable @node Magic Cookies, Reporting Bugs, FTP Commands, Top @chapter Magic Cookies Magic cookies are used in @sc{muddleftpd} user config files and in files displayed to the user. Magic cookies recognized in files are replaced with the values they represent as @sc{muddleftpd} parses them. eg: @example my email is %E @end example has the magic cookie %E. Since %E represents the FTP server maintainer's email address, @sc{muddleftpd} would create the following: @example my email is ekuiperba@@cc.curtin.edu.au @end example All magic cookies in @sc{muddleftpd} start with a % char. There are 2 formats available: The %x Format: This format is simplest syntax and simply replaces the cookie (%x) with the entire string that represents the character x. The %(m,n)x Format: This format selects a range of characters from the string cookie (%x) represents. m is the first character to insert and n is the last character to insert from cookie x. The first character in a magic cookie is numbered is 0. m and n are both adjusted so m >= 0 and n <= length of the Magic cookie. @xref{Magic Cookies}. if n > m, then the cookie is considered invalid, see below. eg. @multitable @columnfractions .20 .8 @item %(0,5)u @tab will give the first six characters of what magic cookie u represents. @item %(10,10)E @tab returns the 11th character of what cookie E represents. @item %(6,8)M @tab returns the 7th to 9th characters from what cookie M represents. @item %(10,8)F @tab This is invalid because n > m. @end multitable Invalid Syntax: If @sc{muddleftpd} determines that a magic cookie is invalid (ie, it doesn't exist or is the format is bad), then the line where the magic cookie was found will not be parsed and an entry (informational) will be added to the log. The following magic cookies are recognized in dumped files: @multitable @columnfractions .1 .9 @item %T @tab The current time in the format: Wed Jan 30 21:49:08 1993 @item %U @tab The username the user used to login @item %C @tab The current directory of the user @item %E @tab The administrators email, set in the main config file @item %M @tab The maximum number of users muddleftpd will log on at a time @item %N @tab The current number of users logged into this muddleftpd server. @item %R @tab The string representation of the remote user's IP (muddleftpd doesn't do reverse name lookup on users) @item %L @tab The full hostname of the host muddleftpd is running on @item %f @tab The number of files the user has downloaded @item %F @tab The number of files the user has uploaded @item %b @tab The number of bytes the user has downloaded, downloading files. @item %B @tab The number of bytes the user has uploaded, uploading files @item %I @tab The number of bytes the user has downloaded, from listings @item %i @tab The number of listings the user has downloaded @item %D @tab The total number of bytes downloaded (listing and file downloads) over data connections. @item %d @tab The total number of connections opened for downloading (listing and file downloads) @item %t @tab The total number of bytes transfered (listing, uploading and downloading) over data connections @item %c @tab The total number of data connections made (for listing, uploading and downloading) @end multitable You can also use the %(m,n)x format on any of the above cookies. (although doing so may not be useful for many of the cookies) The %C magic cookie is invalid during the logindump file, because the user has no current directory before startup. To make user configuration files flexable, a set of magic cookies are accepted in these files. Most of these magic cookies get read from the password file. The following magic cookies are recognized in config files: @multitable @columnfractions .1 .9 @item %U @tab The username of the connecting party @item %p @tab The encrypted password from the normal password file @item %s @tab The encrypted password from the shadow password file (if your system uses shadow passwords) @item %u @tab The uid from the password file @item %g @tab The gid from the password file @item %h @tab The home directory from the password file. @end multitable You can also use the %(m,n)x format on any of the above cookies.

Magic cookies recognized in files are replaced with the values they represent as muddleftpd parses them. eg: my email is %E has the magic cookie %E. Since %E represents the FTP server maintainer's email address, muddleftpd would create the following: my email is ekuiperba@cc.curtin.edu.au 1b) Syntax: All magic cookies in muddleftpd start with a % char. There are 2 formats available: The %x Format: This format is simplest syntax and simply replaces the cookie (%x) with the entire string that represents the character x. The %(m,n)x Format: This format selects a range of characters from the string cookie (%x) represents. m is the first character to insert and n is the last character to insert from cookie x. The first character in a magic cookie is numbered is 0. m and n are both adjusted so m >= 0 and n <= length of the Magic cookie. if n > m, then the cookie is considered invalid, see below. eg. %(0,5)u will give the first six characters of what magic cookie u represents. %(10,10)E returns the 11th character of what cookie E represents. %(6,8)M returns the 7th to 9th characters from what cookie M represents. %(10,8)F This is invalid because n > m. Invalid Syntax: If muddleftpd determines that a magic cookie is invalid (ie, it doesn't exist or is the format is bad), then the line where the magic cookie was found will not be parsed. 2) MAGIC COOKIES IN DUMPED FILES. 2a) Overview: At certain times, muddleftpd can print the contents of a file to the screen in an extended FTP request. eg: 230- 230-Hello rugger@127.0.0.1 230- 230-WELCOME. IF YOU HAVE PROBLEMS WITH THIS SERVER EMAIL: 230- ekuiperba@cc.curtin.edu.au 230- 230 User rugger login successful. Magic cookies can be used in these files to create semi-dynamic content involving the remote user, the current directory, and statistics. 2b) Available Magic Cookies. The following magic cookies are recognized in dumped files: %T The current time in the format: Wed Jan 30 21:49:08 1993 %U The username the user used to login. %C The current directory of the user. %E The administrators email, set in the main config file. (see config.txt) %M The maximum number of users muddleftpd will log on at a time. %N The current number of users logged into this muddleftpd server. %R The hostname of the remote user connected to muddleftpd. %L The hostname of the virtual server the user is on. If no virtual servers are defined, it will be the main hostname/ %f The number of files the user has downloaded. %F The number of files the user has uploaded. %b The number of bytes the user has downloaded, downloading files. %B The number of bytes the user has uploaded, uploading files. %I The number of bytes the user has downloaded, from listings. %i The number of listings the user has downloaded. %D The total number of bytes downloaded (listing and file downloads) over data connections. %d The total number of connections opened for downloading. (listing and file downloads) %t The total number of bytes transfered (listing, uploading and downloading) over data connections. %c The total number of data connections made (for listing, uploading and downloading) %v The name of the section the users virtual server declaration is from. You can also use the %(m,n)x format on any of the above cookies. (although doing so may not be useful for many of the cookies) The %C magic cookie is invalid during the logindump file, (see config.txt) because the user has no current directory before startup. 2c) Examples: Text file that is dumped when someone is logged in: Hello %U@%R. Welcome to %L. You are user %N of %M. Send any problem reports to %E Current time over here is: %(11,18)T The resulting dumped file: 230- 230-Hello rugger&127.0.0.1. 230-Welcome to darkstar.example.net. 230-You are user 1 of 5. 230- 230-Send any problem reports to ekuiperba@cc.curtin.edu.au 230- 230-Current time over here is: 01:31:38 230 User rugger login successful. And the text file that is dumped as the user quits: you downloaded %b bytes in %f files you uploaded %B bytes in %F files you downloaded %I bytes in %i listings in total: download transfers %d downloaded bytes %D total transfers %c total transfered bytes %t The results when the user quits: 221-you downloaded 14082785 bytes in 4 files 221-you uploaded 1727152 bytes in 2 files 221-you downloaded 17015 bytes in 3 listings 221- 221-in total: 221- download transfers 7 221- downloaded bytes 14099800 221- total transfers 9 221- total transfered bytes 15826952 221- 221 muddleftpd Logging out user. after i had down some downloads and uploads and listings. 3) MAGIC COOKIES IN GROUP SECTIONS: 3a) Overview: To make user configuration files flexable, a set of magic cookies are accepted in these files. Most of these magic cookies get read from the authentication module. 3b) Avaliable magic cookies: The following magic cookies are recognized in group sections of config files: (note that some of these cookies are determined by the authetication module and are not avaliable until it has run) %U The username of the connecting party. %v The section name of the virtual server the user is connecting to. %V The host name of the virutal server the user is connecting to. %u The uid from the authentication module. %g The gid from the authentication module. %G A list of suplementary gids from the authentication module. %h The home directory from the authentication module. %r The root directory from the authentication module. You can also use the %(m,n)x format on any of the above cookies. (although doing so may not be useful for many of the cookies) For the authuser, and any directives used by the authentication module, only %U, %v and %V will be avaliable. 3c) Examples See the examples directory for examples of magic cookie usage in user config files. muddleftpd-1.3.13.1/doc/ftpcmds.txt0100644000175000017500000000364507556000671016051 0ustar joergjoerg MUDDLEFTPD DOCUMENTATION (Version 1.3.4) Beau Kuiper (support@muddleftpd.cx) License under GPL 1) FTP COMMANDS 1a) Command List The following commands are understood and used by muddleftpd: PORT Define the data port the server will connect to.

Muddleftpd has been tested on FreeBSD, linux with libc5, linux with glibc2, Irix 5.3, solaris 2.6, linux with glibc2.1 and Sun-os. * GNU gcc or any gcc compatible compiler (egcs, etc). I will accept patches to make muddleftpd compile on non-gcc compilers (as long as nothing breaks). * GNU make. Other makes seem to get confused about what I use in the Makefile 1b) Building muddleftpd: * Run the following command in the top level directory ./configure or if you wish to specify a prefix directory to install (eg /usr/local) ./configure --prefix= * Open defaults.h. There is a #define CONFIGFILEE statement in the first few lines. eg: #define CONFIGFILE "/etc/muddleftpd/ftpd.conf" If this is not where you want to place the main config file, then modify it to the location and filename you wish use instead. If you don't perform this step, muddleftpd and ftpwho will need to be manually told where their configuration files are each time they are started. * run the following to create the executables: make if you want to create a version that doesn't output startup messages, run: make QUIET=1 NOTE: on some systems you may need to run gmake instead of just make. 1c) Installing muddleftpd: * run the following to install muddleftpd: make install * Create the configuration at the location you specified in CONFIGFILE above. You may use one of the example configurations (standard set is recommended), see examples/README for more information. 1d) Running muddleftpd: To start muddleftpd, type muddleftpd [configfile] If you specify [configfile], then it will use [configfile] as the main configuration file instead of the one compiled into muddleftpd. If you want muddleftpd to run each time you boot the system up, then you need to put the muddleftpd statement above into one of your startup files, probably /etc/rc.d/rc.local (on linux systems) 2) TROUBLESHOOTING: 2a) Compile Problems: If problems occur while compiling, check the following: * If you are running OpenLinux 2.2, make sure that you have downloaded and installed the crypt package. Get it from: ftp://ftp.linuxland.de/pub/OpenLinux/crypto/2.2/glibc-crypt-2.1-3i.i386.rpm Everything should compile OK then. 2b) Running problems: If you get the message: ---------------------------------------------------------------------------- muddleftpd error in file init.c line 51: muddleftpd already running! CANNOT RESUME. Goodbye This means that you are already running a copy of muddleftpd using the configuration file muddleftpd tried to open. (That is, the default compiled in config file, or what you specified on the command line). Simply close down the old version (with a SIGTERM) and start it again. ---------------------------------------------------------------------------- muddleftpd error in file shmem.c line 91: Permission denied CANNOT RESUME. Goodbye This means that muddleftpd could not get write permission on the main configuration file (It is used for locking the shared memory). You must give the user running muddleftpd write permission to the main config file muddleftpd will be running as. ----------------------------------------------------------------------------muddleftpd-1.3.13.1/doc/mudlogd.txt0100644000175000017500000000331007556000671016031 0ustar joergjoerg MUDDLEFTPD DOCUMENTATION (Version 1.3.10) Beau Kuiper (support@muddleftpd.cx) License under GPL This is a quick guide to using mudlogd. Mudlogd is a deamon designed to make rotating muddleftpd log files simple, without bothering the main server. Muddleftpd isn't able to rotate its log files sometimes because it has lost the permissions or file access to do so. Mudlogd overcomes this by providing muddleftpd a single place to store logs and then handling rotation itself Although designed for muddleftpd, mudlogd can also be used by almost any program. Simply substitue any references to muddleftpd with your favourite program and its configuration requirements. Using mudlogd: 1) Decide a directory and filename to store the fifo object muddleftpd needs to communicate with mudlogd. Make sure this file cannot be modified/deleted by other local users. 2) Create a configuration file containing the following: [section] logger logfile /var/log/muddleftpd.conf fifoname /etc/muddleftpd/mudlog Replace the parameter on logfile with the output log file you wish to use. Replace the parameter on fifoname with the filename you decided in part 1. 3) In the muddleftpd configuration file. set the logfile directives for the servers and virtual servers that will use mudlogd to the filename you decided in part 1. 4) Start muddleftpd by running: mudlogd -c /etc/muddleftpd/mudlogd.conf muddleftpd -c /etc/muddleftpd/muddleftpd.conf Replace the configuration files specified above with the ones created for mudlogd and muddleftpd. 5) You can rotate the logs now using logrotate, or by using the following: mv /var/log/muddleftpd.log /var/log/muddleftpd.log.old killall -SIGUSR1 mudlogd muddleftpd-1.3.13.1/doc/mudpasswd.txt0100644000175000017500000000227207556000671016413 0ustar joergjoerg MUDDLEFTPD DOCUMENTATION (Version 1.3.4) Beau Kuiper (support@muddleftpd.cx) License under GPL 1) THE MUDPASSWD PROGRAM 1a) Building mudpasswd: The internal password module, uses its own password modification utility. This utility will be built when you build muddleftpd. 1b) Installing mudpasswd: Installed with the rest of muddleftpd. Note that it refused to be setuid root. This is because you can do much damage with it! 1c) Running mudpasswd: To add a user to a password file: mudpasswd -p -a You may also specify -P to set the password, -R to set the root directory, -H to set the home directory if you don't specify any of these, then mudpasswd will ask for them before creating the user To delete a user from a password file: mudpasswd -p -d To edit a user in a password file: mudpasswd -p -e (option to change) You must also specify what to change: -P to set a new password, -R to set a new root directory, -H to set a new home directory, -W to get mudpasswd to ask for a new password muddleftpd-1.3.13.1/doc/reference.txt0100644000175000017500000015456507556000671016357 0ustar joergjoergMuddleftpd reference text.

If [DIR] ends with /, then muddleftpd assumes it is refering to a directory and permissions only apply to files in the directory, not [DIR] itself. Otherwise, muddleftpd assumes it is a file, and the permissions will only apply to that filename. [MODE] is documented in 1.2.1. WARNING: when a symbolic link is encountered, muddleftpd will apply the access directives to the symbolic link only, not to the destination of the symbolic link. Users who can create symbolic links in the same areas they access with the ftp server will be able to easily circumvent the access directives. Therefore you MUST not depend on access being safe in groups where the user can create symbolic links in the same area as they can access via the ftp server. 1.1.2.2 "altlongreplies" directive Used in: main section Syntax: altlongreplies [VALUE] Examples: altlongreplies 0 # use rfc format for long replies altlongreplies 1 # use more compatible format for # long replies Cookie support: No Default: altlongreplies 0 altlongreplies makes muddleftpd use a different format for long FTP replies. When set to 1, it uses the following format for long replies: 220-Start long reply 220-Contiune 220 End long reply When set to 0, it uses this format: 220-Start long reply Continue 220 End long reply. When set to 1, muddleftpd may be more compatible with older clients and proxies. 1.1.2.3 "authmethod" directive Used in: group sections Syntax: authmethod [modulename] Examples: authmethod pam # use pam to authenticate users authmethod unix # use unix passwd to authenticate # users. authmethod /etc/muddleftpd/libauthmysql.so # use external authentication module. Cookie support: Yes, see 1.2.2 Default: (none), you must specify this. authmethod sets how muddleftpd chooses a user's group and how that user is authenticated. You can specify one of the internal authentication modules (unix,pam,internal,anonymous,deny) or an external module. If you use an external authentication module, its full path MUST be specified. Section 2.0 outlines 1.1.2.4 "authuser" directive Used in: group sections Syntax: authuser [username] Examples: authuser %U # no rewriting. authuser %U-servb # add the suffix -servb to the # username authuser %(5,100)U # remove first 5 characters of # username Cookie support: Yes, see 1.2.2 Default: authuser %U Authuser allows the server to do some very basic rewriting of the username before passing it to the authentication module (specifed in authmodule). This re-written username is ONLY used when communicating with the authentication module, and the original username is used everywhere else. 1.1.2.5 "badauthwait" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: badauthwait [milliseconds] Examples: badauthwait 2000 # wait 2 seconds badauthwait 500 # wait 1/2 second Cookie support: No Default: badauthwait 3000 When a login fails (PASS command) for any reason, muddleftpd will wait a defined time before accepting a new command. Use this option to specify an appropriate time for muddleftpd to wait. 1.1.2.6 "busydump" directive Used in: group sections Syntax: busydump [filename] Examples: busydump /etc/muddleftpd/TOOBUSY # print this when too many users # are on Cookie support: Yes, see 1.2.2 Default: (none) When the server cannot log a user into a particular group due to maxusers limits, it will print this message before disconnecting the user from the server. This is not used when the server's or the virtual server's maxusers limit is reaches. When this occurs, the user is simply disconnected without any messages. Section 1.2.4 documents cookies you can use in files specified with this directive. The file must given with a full path. 1.1.2.7 "busydumpdata" directive Used in: group sections Syntax: busydumpdata [dump-string] Examples: busydumpdata Cannot log you in/nMaximum %M users exceeded./n # print this when too many users # are on Cookie support: Yes, see 1.2.4 Default: (none) This command is exactly like busydump (1.1.2.7), except the actual data is stored in the config file instead of an external file. The format for [dump-string] is described in section 1.2.3. This overrides any busydump directives in the same section. 1.1.2.8 "byteratios" directive Used in: group sections, only valid if ratios is set to 1 Syntax: byteratios [down:up] Examples: byteratios 10:3 # for every 3 bytes the user uploads # give 10 bytes of download credit. byteratios 1:5 # for every 5 bytes the user uploads # give 1 byte of credit. Cookie support: No Default: (none) This directive sets the ratios that will be placed on byte usage for users not found in the ratio file. (users in the ratio file have already got a ratio stored) If no ratio file is given, this will always be used. 1.1.2.9 "cddump" directive Used in: group sections Syntax: cddump [filename] Examples: cddump README # print the README file in the # directory the user is entering cddump /etc/cdinfo # print /etc/cdinfo out. Cookie support: Yes, see 1.2.2 Default: (none) When a user changes directory, this file will be printed. If it is relative filename (no / at the beginning), then the file will relative to the new directory the user is entering. A relativly specified file will also have to be normally accessable to the user via permissions and access directives. If the file is specified absolute (with a / at the beginning) then muddleftpd will not check it against access directives. Absolute files are not relative to rootdir. 1.1.2.10 "cddumpdata" directive Used in: group sections Syntax: cddumpdata [dump-string] Examples: cddumpdata You changed dir/nIt is now %C/n # print this when muddleftpd changes # dir Cookie support: Yes, see 1.2.4 Default: (none) This command is exactly like cddump (1.1.2.9), except the actual data is stored in the config file instead of an external file. The format for [dump-string] is described in section 1.2.3. This overrides any cddump directives in the same section. 1.1.2.11 "chmoding" directive Used in: group sections Syntax: chmoding [0 or 1] Examples: chmoding 1 # allow site chmod chmoding 0 # disallow site chmod Cookie support: Yes, see 1.2.2 Default: chmoding 0 This command controls whether users can change the permissions on files using "site chmod". By default, it is 0 and users cannot change file permissions on ANY files. Setting it to 1 will enable this ability. 1.1.2.12 "chroot" directive Used in: group sections Syntax: chroot [VALUE] Examples: chroot 1 # chroot after successful login chroot 0 # don't chroot after successful # login Cookie support: Yes, see 1.2.2 Default: chroot 0 This controls whether muddleftpd will change the system root directory to the users rootdir after login is complete. This means symbolic links that point outside of the users rootdir will NOT work. It has the following side effects: 1) userjail is set to 1, thus the user cannot login again. 2) welcome, cddump and quitdump, will complain if you attempt to use files outside of rootdir 3) log messages for file operations will now have filenames absolute to the user's rootdir. (may be fixed later) 4) log rotation will not be done for any muddleftpd process that has performed chroot. 1.1.2.13 "cmdoff" directive Used in: group sections Syntax: cmdoff [CMD] Examples: cmdoff SITE # disable all site commands. cmdoff PASV # disable passive transfers. cmdoff DELE # disable file deletion. Cookie support: Yes, see 1.2.2 Default: (none) This directive disables FTP commands. This can disable things like file rename, deleting, storing files, ect. When commands are disabled, they appear unimplemented to the user (ie, they become no different to commands that don't exist). See section 3.1 for commands that can be disabled with this command. 1.1.2.14 "devaccess" directive Used in: group sections Syntax: devaccess [VALUE] Examples: devaccess 1 # enable access to device files. devaccess 0 # disable access to device files. Cookie support: Yes, see 1.2.2 Default: devaccess 0 This directive sets whether users in a group can access device files. The default is to disallow this, although it does incur a very small performace penalty. (file must be checked to make sure it isn't a device). Attempting to access a device will result in a permission error. 1.1.2.15 "droproot" directive Used in: group sections Syntax: droproot [VALUE] Examples: droproot 1 # drop all root privliges after # login droproot 0 # don't drop root privliges. Cookie support: Yes, see 1.2.2 Default: droproot 0 This directive sets whether the server will drop all root privlidges after login. When enabled, security for the paranoid is enhanced (muddleftpd doesn't have root exploits), but: 1) muddleftpd cannot bind the server data port to 20. This means that ftp clients may not work through firewalls. However, this limitation will automaticly be removed if you have linux and the capibilities library installed. 2) userjail is set to 1. (user cannot relogin as another user) 3) logfiles cannot be rotated by any muddleftpd process that has a user logged into a group where droproot is set. 1.1.2.16 "email" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: email [STRING] Examples: email ftpadmin@ftp.host.com # set email to this email user@hostname # another silly example Cookie support: No Default: email ftp@localhost This sets the email address returned when the HELP ftp command is used, and when the %e cookie is used in dumped files or strings. This can be anything you want really. 1.1.2.17 "fakegroup" directive Used in: group sections Syntax: fakegroup [STRING] Examples: fakegroup mudgroup # set group to mudgroup fakegroup anonymous # set group to anonymous Cookie support: Yes, see section 1.2.2 Default: (none) This is used to hide all group names in all listings, replacing them with the name you specify for the given group. This can hide the real group names in the group files from ftp users. 1.1.2.18 "fakemode" directive Used in: group sections Syntax: fakemode [OCTAL-VALUE] Examples: fakemode 777 # set mode to rwxrwxrwx fakemode 700 # set mode to rwx------ Cookie support: Yes, see section 1.2.2 Default: (none) This specifies that listings should always return a certain mode for filenames. This hides the real permissions from the ftp user. 1.1.2.19 "fakename" directive Used in: group sections Syntax: fakename [STRING] Examples: fakename mud # set username to mud fakename mp3 # set username to mp3 fakename %U # set username to the login username Cookie support: Yes, see section 1.2.2 Default: (none) This specifies that listings should always return a certain user ownership for files. This hides the files original owner from ftp users. 1.1.2.20 "fileratios" directive Used in: group sections, only valid if ratios is set to 1 Syntax: fileratios [down:up] Examples: fileratios 2:1 # for every file the user uploads # allow 2 to be downloaded fileratios 1:5 # for every 5 bytes the user uploads # give 1 byte of credit. Cookie support: No Default: (none) This sets inital ratios on how many files a user must upload to how many credits they recieve for doing so. This will not override information in the ratio file. If no ratio file is specified, this is always used. 1.1.2.21 "fnaccess" directive Used in: group sections Syntax: fnaccess [PATTERN]:[MODE] Examples: fnaccess *.mp3:NONE # no access to files with mp3 # extension fnaccess *.o:NONE # no access to object files. fnaccess /home/%U/*:R # give read access to all files in # user home dir and subdirs Cookie support: Yes, see section 1.2.2. Default: (none) This specifies access setting using basic regular expressions. fnaccess setting have priority over regular access directives, so care must be exercised in the specifing fnaccess directives. Eg, access /:C access /home/mud/:LC fnaccess *.c:R will allow access to filenames /a.c or /home/a.c. Also, fnaccess directives are checked in the order they are specified in the config file, so fnaccess directives specified earilier have higher priority over fnaccess directives specified later. WARNING: when a symbolic link is encountered, muddleftpd will apply the fnaccess directives to the symbolic link only, not to the destination of the symbolic link. Users who can create symbolic links in the same areas they access with the ftp server will be able to easily circumvent the fnaccess directives. Therefore you MUST not depend on fnaccess being safe in groups where the user can create symbolic links in the same area as they can access via the ftp server. 1.1.2.22 "ftpport" directive Used in: either the main section or virtual server sections. If used in the main section when virtual servers are defined, then the declaration in the main section is ignored. Syntax: ftpport [PORTNUM] or ftpport [PORTNUM]:[IPADDR] Examples: ftpport 21 # bind to port 21, all interfaces ftpport 21:10.1.1.1 # bind to port 21, interface # on 10.1.1.1 only ftpport 4008 # bind to port 4008. Cookie support: No Default: (none), must be specified. This directive specifies what ports muddleftpd will listen for connections on. It may be specified more than once in the same section, where muddleftpd will listen for all specified ports. If you don't supply the ip of an interface to bind to, muddleftpd will listen on all ports. When setting up virtual servers, it is often done by using the same port, while using a different ip for the interface in each virtual server definition. 1.1.2.23 "fxpallow" directive Used in: group sections Syntax: fxpallow [VALUE] Examples: fxpallow 0 # disallow server-server transfers. fxpallow 1 # allow server-server transfers. Cookie support: Yes, see section 1.2.2. Default: fxpallow 0 This directive specifies whether users of a particular group can perform server to server transfers. It is highly recommended that you do not set this unless you really, really need to. Setting this to true allows users to send a file to an abitary port (above 1024) on any remote server. It also allows a third party to steal a passive connection from a user from any remote computer. 1.1.2.24 "gid" directive Used in: group sections Syntax: gid [VALUE or NAME] Examples: gid %g # set gid from users gid from authentication # module gid 10 # set users group to 10 gid ftpuser # set the users group to ftpuser. Cookie support: Yes, see section 1.2.2. Default: gid %g This specifies what gid a user connected to the server will use to access files. It can be specified using a group name or an integer group value. By default, the gid from the authentication module is used. If you set it to 0 (the root group), then muddleftpd will automaticly demote it to nobody's group. 1.1.2.25 "greeting" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: greeting [STRING] Examples: greeting Welcome to %L # set greeting to display # server name Cookie support: Yes, see section 1.2.4 Default: greeting muddleftpd (1.3.4-devel) server ready. Enter Username. Sets the greeting line when a person connects to the server. This accepts all of the cookies the logindump file will accept. This is used to personalize your server and hide the server name, version from users. 1.1.2.26 "group" directive Used in: either the main section or virtual server sections. If used in the main section when virtual servers are defined, then the declarations in the main section are ignored. Syntax: group [SECTION] Examples: group badusers # set to check badusers section first group anonymous # set to check anonymous section next group users # set to check users section last or group badsites # check badsites section first group users # then users section next Cookie support: No Default: (none), must be specified. This directive sets the sections muddleftpd will check as groups when logging someone in to the server, or one of its virtual servers. The groups are checked in the same order as specified in the config file. Group sections are discussed in detail in section 1.0.3 1.1.2.27 "homedir" directive Used in: group sections Syntax: homedir [DIRECTORY] Examples: homedir / # set homedir to same as rootdir homedir %h # set homedir to homedir from # authentication module. Cookie support: Yes, see section 1.2.2. Default: homedir %h This directive describes the home directory a user logging in will have. It is ALWAYS relative to the rootdir. This is so users don't have homedir's outside of their root directory. By default, homedir is set by the authentication module. 1.1.2.28 "hostname" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: hostname [STRING] Examples: hostname mud.serious.net # a hostname hostname hostname # another example Cookie support: No Default: (same as the hostname from /etc/HOSTNAME) This sets the hostname muddleftpd will report to users when they use the ftp server. It sets the %L cookie for files dumped to the user (see section 1.2.4). It also sets the %V cookie for group sections (see section 1.2.2) 1.1.2.29 "include" directive Used in: anywhere Syntax: include [SECTIONNAME] Examples: include asection # include section asection Cookie support: No Default: (none) This is a low level function that allows a section to be included into another section. No cookies are interpretted by include. An example: [section] a hostname v access /:ALL access /test/:NONE [section] b access /:NONE include a access /test/:ALL when section b is interpreted, will become access /:NONE hostname v access /:ALL access /test/:NONE access /test/:ALL Here, the included data is inserted in order, so you must be careful of the order the final result will be. In this example, the access to / is overriden by the data in the included section. 1.1.2.30 "initalbytes" directive Used in: group sections, only valid if ratios is set to 1, and byteratios is set (see 1.1.2.8) Syntax: initalbytes [64bit-INT] Examples: initalbytes 2000000 # give 2 meg of inital credits. initalbytes 0 # give 0 meg of credits initally. Cookie support: No Default: (none) This sets how many byte credits a user has initally when using ratios. If you have ratiofile defined, then this is only used for new users. Otherwise the setting will be read from the ratiofile. This is specified as a 64-bit integer (ie, can have virtually any size) 1.1.2.31 "initalfiles" directive Used in: group sections, only valid if ratios is set to 1, and fileratios is set (see 1.1.2.20) Syntax: initalfiles [COUNT] Examples: initalfiles 100 # give 100 inital file credits. initalfiles 0 # give 0 file credits initally. Cookie support: No Default: (none) This sets how many file credits a user has initally when using ratios. If you have ratiofile defined, then this is only used for new users. Otherwise the setting will be read from the ratiofile. 1.1.2.32 "ipacl" directive Used in: main, vserver and group sections Syntax: ipacl [A or D]/[IP]/[NETMASK] ipacl [A or D]/[IP-PATTERN] ipacl [A or D]/([HOST-PATTERN]) Examples: ipacl A/10.1.1.0/255.255.255.0 # allow 10.X.X.X ipacl A/127.* # allow localhost addresses ipacl A/(localhost) # allow hostname localhost ipacl A/(*.edu) # allow any .edu address ipacl D/(*.com.??) # disallow country .com Cookie support: No Default: ipacl D/* Ipacl is a generic way of declaring what IP address/hostnames have access to something. The first format above allows you to specify a range of IP's using an ip address and a netmask. The second format allows you to specify a range of IP's using a basic regular expressions. The third fromat allows you to sepecify a basic regular expression to match the user's hostname. You must be very careful when using regular expressions against hostnames. Users may spoof DNS and their hostname, allowing them to get accesss they otherwise shouldn't have. Ipacl's are checked in the order they are in the config file. The first ipacl to match the user's hostname or IP will decide the access of a particular user. The access a user will get is defined by the first character before ':', an 'A' will grant access, anything else will deny it. When used in the main section, ipacl controls who is given access to the server. If the user is not accepted by these controls, they are dumped from the server immediately. If virtual servers are defined, ipacl's in the virtual server section decide if the user is accepted into the server (after the main ones are checked). In group sections, ipacl controls if a user can login to that group after the user has entered a username/password. If the user is not accepted, muddleftpd will check the next group. 1.1.2.33 "logfile" directive Used in: virtual server sections or the main section. Syntax: logfile [FILENAME] Examples: logfile /var/log/ftpd.log # set logfile Cookie support: No Default: logfile /var/log/muddleftpd.log Sets the logfile for muddleftpd logs. This file must be an absolute filename. When defined in virtual server sections, muddleftpd will log information users using that virual server into that file instead of the main log file. The parameter to logfile must be an absolute filename. (ie start with /) 1.1.2.34 "logindump" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: logindump [filename] Examples: logindump /etc/issue # print this before user logs in Cookie support: No Default: (none) When a new user connection to the server occurs, this is printed before the greeting (see section 1.1.2.25). All new users will see this file before they login using a username/password. 1.1.2.35 "logindumpdata" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: logindumpdata [dump-string] Examples: logindumpdata Welcome/nThis server will allow %M users./n # print this when a user connects Cookie support: Yes, see 1.2.4 Default: (none) This command is exactly like logindump (1.1.2.32), except the actual data is stored in the config file instead of an external file. The format for [dump-string] is described in section 1.2.3. This directive overrides any logindump directives in the same section. 1.1.2.36 "logintries" directive Used in: virtual server sections or the main section. If virtual servers are defined, any occurence in the main section is taken as the default for virtual servers. Syntax: logintries [COUNT] Examples: logintries 10 # give 10 tries to login. logintries 1 # give only one try to login. Cookie support: No Default: logintries 3 This command limits the number of incorrect username/password combinations a connection can make before it is locked out. After this, any USER command the client will fail. This can slow down the brute forcing of passwords. 1.1.2.37 "logstrength" directive Used in: virtual server and main sections. Syntax: logstrength [VALUE] Examples: logstrength 63 # Log Everything logstrength 25 # Log bad connections, commands # resposes and generic info. Cookie support: No Default: logstrength 63 This command sets how much logging muddleftpd and/or its virtual servers will perform. It is a value created by adding up one or more of the following numbers: 1 Log connections that fail due to ipacl settings 2 Log file transfers (uploads, downloads, SITE DUMP) 4 Log command the client sends to the server. 8 Log responses to commands the client sends. 16 Log generic information, including config errors (highly recommended) 32 Log successful/unsuccessful logins and logouts of clients. So to log file transfers and generic information, use a setting of 18. 1.1.2.38 "maxconnectperip" directive Used in: virtual server sections or the main section. Syntax: maxconnectperip [COUNT] Examples: maxconnectperip 0 # set no limit maxconnectperip 2 # only 2 connections from the same # ip Cookie support: No Default: maxconnectperip This directive limits the number of logins from the same IP address to the server (or one of its virtual servers). This options will reduce the login performace of the server if it is running in standalone mode. If used in the main section, it sets the total number of connections from any one IP regardless of the virtual server the client is connected to. When used in virtual server sections, it will only affect conections to that single virtual server. 1.1.2.39 "maxspeed" directive Used in: group sections Syntax: maxspeed [BYTES-PER-SECOND] Examples: maxspeed 4096 # set max transfer speed to 4096 b/s maxspeed 1000000 # set max transfer speed to 1 Meg/sec Cookie support: Yes, see section 1.2.2. Default: (none) This directive specifies how fast a user may download/upload data at. This can be used to conserve bandwidth/annoy users. The value used is specified in bytes per second. Control port data is not affected by this command, so you may wish to also use the directive "sitecmdoff dump" when using this option. 1.1.2.40 "maxusers" directive Used in: main, vserver and group sections Syntax: maxusers [COUNT] Examples: maxusers 100 # set maximum users to 5 maxusers 0 # allow no users, hide group. Cookie support: No Default: maxusers 30 maxusers sets the maximum number of users for a server, a virtual server, or for a group. When used in the main section, maxusers will set the maximum number of users the server will allow in. Any connections that would exceed this count are immediately dropped, without any messages. When used in a virtual server section, maxusers will set the maximum number of users the server will allow to connect to that virtual server. As with the main section, connections that overflow that count will be dropped. In group sections, maxusers sets the maximum number of users that can login via that group. When that limit is reached, new connections will be given the busydump message and disconnected instead of quietly disconnected. When maxusers is set to 0 in a group section, that group will not be displayed in ftpwho listings. 1.1.2.41 "nameacl" directive Used in: group sections Syntax: nameacl [A or D]:[PATTERN] Examples: nameacl A:* # accept any username nameacl A:anonymous # accept only anonymous. nameacl D:root # deny username root. Cookie support: No Default: nameacl D:* This directive declares which usernames will be accepting when attempting to authenticate against a group. nameacl directives are checked in order, and the first one to match the username will determine the final result. If the final result is accept, than the username will continue to be authenticated against that group. If the final result is deny, muddleftpd will try the next group. 1.1.2.42 "nice" directive Used in: group sections Syntax: nice [VALUE] Examples: nice -20 # give very low priority nice 5 # give higher priority. Cookie support: Yes, see section 1.2.2. Default: nice 0 This directive sets the CPU priority of a user in a group after they have logged on. VALUE may be from -20 (highest priority) to 20 (lowest priority) with 0 being normal priority. Note that you cannot use negative values unless you run muddleftpd as root and runasuser isn't set. 1.1.2.43 "pfnaccess" directive Used in: group sections Syntax: pfnaccess [PATTERN]:[MODE] Examples: pfnaccess /b/*.mp3:NONE # no access to files with mp3 # extension in only the b dir pfnaccess /*.o:NONE # no access to object files in root # dir. pfnaccess /home/%U/*:R # give read access to all files in # user home dir and subdirs Cookie support: Yes, see section 1.2.2. Default: (none) This specifies access setting using basic regular expressions, however wildcard characters cannot match / characters, so only a single directory is affected. pfnaccess have lower priority to fnaccess, and higher priority to plain access. All the rules for fnaccess (see section 1.1.2.21) also apply to pfnaccess. 1.1.2.44 "quitdump" directive Used in: group sections Syntax: quitdump [filename] Examples: quitdump /etc/muddleftpd/BYEMSG # print this when user exits Cookie support: Yes, see 1.2.2 Default: (none) When a user quits muddleftpd, the data from the specified filename will be printed to the user as they leave. Section 1.2.4 documents cookies you can use in files specified with this directive. The file must given with a full path. 1.1.2.45 "quitdumpdata" directive Used in: group sections Syntax: quitdumpdata [dump-string] Examples: quitdumpdata Thank you/nYou downloaded %b bytes./n # print this when user exits Cookie support: Yes, see 1.2.4 Default: (none) This command is exactly like quitdump (1.1.2.40), except the actual data is stored in the config file instead of an external file. The format for [dump-string] is described in section 1.2.3. This overrides any quitdump directives in the same section. 1.1.2.46 "ratios" directive Used in: group sections. Syntax: ratios [0 or 1] Examples: ratios 1 # enable ratios. Cookie support: Yes, see section 1.2.2 Default: ratios 0 This directive specifies whether a user in a group will be subject to ratios. These ratios are specified by: byteratios (see section 1.1.2.8) fileratios (see section 1.1.2.20) initalbytes (see section 1.1.2.30) initalfiles (see section 1.1.2.31) ratiofile (see section 1.1.2.47) 1.1.2.47 "ratiofile" directive Used in: group sections, only valid if ratios is set to 1 Syntax: ratiofile [filename] Examples: ratiofile /etc/ratios ratiofile /home/rugger/ratios # location of persistant # ratios Cookie support: No Default: (none) This directive specifes that persistant ratios are to be used, and that ratio information will be stored in the given file. The given file must be specified with a full path (absolute path). This file will store what a users private ratios are and what credits (byte, file) they have. This file is in a binary format, and cannot be freely moved between differnent types of systems. Using persistant ratios also causes a signifcant performace drop in muddleftpd, since a lot of file access must occur to keep ratio data consistant. Make sure the ratio file is stored on a filesystem that isn't mounted syncronously (ie not write-back cache) otherwise performace will be terrible. 1.1.2.48 "rdnstimeout" directive Used in: main section Syntax: rdnstimeout [VALUE] Examples: rdnstimeout 0 # disable reverse lookup. rdnstimeout 10 # allow reverse lookup 10 seconds. Cookie support: No Default: rdnstimeout 15 rdnstimeout sets the amount of time muddleftpd will wait for reverse DNS lookups to occur. During this time, muddleftpd will be non-responsive. If set to 0, reverse DNS lookups will be disabled. If reverse DNS lookup fails or times out, muddleftpd will use the IP address of the host to identify it. 1.1.2.49 "realdir" directive Used in: group sections Syntax: realdir [0 or 1] Examples: realdir 0 # don't resolve symlinks. realdir 1 # resolve symlinks Cookie support: Yes, see section 1.2.2. Default: realdir 0 This specifies whether muddleftpd will attempt to resolve the real directory when a user changes to a new directory. If set, muddleftpd will resolve symlinks when changing directories if the resultant directory is within rootdir. If the user changes to a symlink that points outside of rootdir, muddleftpd will not resolve it to its real directory. 1.1.2.50 "rootdir" directive Used in: group sections Syntax: rootdir [DIRECTORY] Examples: rootdir / # set rootdir to system rootdir rootdir %r # set rootdir from auth module rootdir %h # set rootdir to users home # directory. Cookie support: Yes, see section 1.2.2. Default: rootdir %r This sets the root directory of a user in a group. rootdir must be specified with a full pathname. By default, rootdir is set by the authentication module. A user can only enter directories outside of rootdir with symlinks (use chroot to disable this). rootdir will appear to be "/" to the logged in user. 1.1.2.51 "runasuser" directive Used in: main section Syntax: runasuser [username] Examples: runasuser rugger # run as user rugger runasuser ftp # run as ftp user Cookie support: No Default: (none) runasuser instructs muddleftpd to switch to a new uid/gid specified by username after initalizing. This will prevent these things occuring in addition to things that don't work without root: 1) log rotation will not work. 2) data ports binding to port 20. 1.1.2.52 "sitecmdoff" directive Used in: group sections Syntax: sitecmdoff [CMD] Examples: sitecmdoff IDLE # disable site idle command. sitecmdoff DUMP # disable site dump command Cookie support: Yes, see 1.2.2 Default: (none) This directive selectivly disables FTP SITE commands. This can disable things like SITE ACCESS and SITE DUMP, that may improve security when using other commands. 1.1.2.53 "smartbind" directive Used in: main section Syntax: smartbind [0 or 1] Examples: smartbind 0 # use simple binding method smartbind 1 # use smart binding method Cookie support: No Default: smartbind 0 This directive instructs whether muddleftpd will take all the ports/IP's it needs to listen to and collate them to use fewer file descriptors. Set to 1 to use smart binding, 0 otherwise. For example: ftpport 21/10.1.1.1 ftpport 21/127.0.0.1 ftpport 21/10.1.1.2 With simple binding, muddleftpd will simply bind each port individually and use 3 file descriptors. With smart binding, muddleftpd will bind to all interfaces on port 21, using one file descriptor. However, connections from extra interfaces that are bound by smart binding will simply be dropped and other programs will not be able to use them. NOTE: You must set smartbind to 1 if you wish to bind to individual interfaces on most unix systems. On these unix systems, you must also set zerobind to 1 as well. 1.1.2.54 "supgid" directive Used in: group sections Syntax: supgid [SUP-GIDS] Examples: supgid %G,1 # add 1 to supgids supgid 1,2,3 # set supgids to 1, 2 and 3 supgid %G,!10 # set supgids to authentication # module, but remove group 10 supgid * # set no sup groups. Cookie support: Yes, see section 1.2.2. Default: supgid %G supgid supplies a comma separated list of supplementary groups a user will be in. Using * will cause no supplementary groups to be set. You can prefix a group number with "!" to remove any eariler occurences of that group number in the list. 1.1.2.55 "timeout" directive Used in: main, vserver and group sections Syntax: timeout [VALUE] Examples: timeout 15 # give 15 second timeout timeout 7200 # give 2 hour timeout Cookie support: Yes, but only in group sections, see section 1.2.2. Default: timeout 300 Timeout sets the amount of time the server will wait for a user response before disconnecting that user. If used in the main section or virtual server sections, timeout specifies the timeout while the user logs in. If used in a group section, it specifies the timeout after a user is logged into that group. 1.1.2.56 "uid" directive Used in: group sections Syntax: uid [VALUE or NAME] Examples: uid %u # set uid from users uid from authentication # module uid 10 # set users uid to 10 uid ftp # set the users uid to ftp. Cookie support: Yes, see section 1.2.2. Default: uid %u This directive specifies what user id a user will access/create files as. It can be speciifed either using an integer user id or a normal username. By default, the uid from the authentication module is used. If you set it to 0 (the root user), then muddleftpd will automaticly demote it to nobody's user id. 1.1.2.57 "umask" directive Used in: main, vserver and group sections Syntax: umask [OCTAL-VALUE] Examples: umask 777 # make new files with no permisions umask 666 # make new files with only execute # permissions if directories. umask 022 # make new files only writeable by # owner Cookie support: Yes, but only in group sections, see section 1.2.2. Default: (default system umask) This sets the umask used when users create files using the ftp server. When used in the main section, it sets the default for any virtual server or groups. When set in a virtual server section it sets the default for groups used by that virtual group. If used in a group section, it overrides any other setting. Umask is defined by an octal value. Users can change their umask using SITE UMASK unless the command is disabled or chmoding is set to 0. 1.1.2.58 "userjail" directive Used in: group sections Syntax: userjail [0 or 1] Examples: userjail 0 # User can relogin. userjail 1 # User cannot change username Cookie support: Yes, see section 1.2.2. Default: userjail 0 This specifies whether the user logged into a particular group can relogin as a different username without disconnecting. If set to 1, the user cannot relogin, otherwise the user will be able to use the USER command to login as a different username. This is automaticly set to 1 if droproot (see section 1.1.2.15) and/or chroot (see section 1.1.2.12) are set to 1, since not enough resources will be avaliable to change the users identity. 1.1.2.59 "vserver" directive Used in: main section. Syntax: vserver [SECTION] Examples: vserver internal # declare section internal as a # virtual server. vserver external # declare section external as a # virtual server. Cookie support: No Default: (none) This directive, if used in the main section, changes muddleftpd behaviour from being a regular server to a virtual server system. This directive is used to declare what sections in the config file are to be definitions for virtual server. By specifiing this directive multiple times in the main section, muddleftpd will declare multiple virtual servers. For more information on virtual server sections, see 1.0.2. If this directive is not used, muddleftpd assumes that main defines server information. 1.1.2.60 "welcome" directive Used in: group sections Syntax: welcome [filename] Examples: welcome /etc/muddleftpd/WELCOMEMSG # print this when user logs into a # group Cookie support: Yes, see 1.2.2 Default: (none) When a user logs into a group successfully, the data from the specified filename will be printed to the user. Section 1.2.4 documents cookies you can use in files specified with this directive. The file must given with a full path. 1.1.2.61 "welcomedumpdata" directive Used in: group sections Syntax: welcomedumpdata [dump-string] Examples: welcomedumpdata You have logged in/nThere are %N users./n # print this when user logs on. Cookie support: Yes, see 1.2.4 Default: (none) This command is exactly like welcome (see 1.1.2.60), except the actual data is stored in the config file instead of an external file. The format for [dump-string] is described in section 1.2.3. This overrides any quitdump directives in the same section. 1.1.2.62 "zerobind" directive Used in: main section, ignored if smartbind (see 1.1.2.53) is not set to 1 Syntax: zerobind [0 or 1] Examples: zerobind 0 # bind to individual interfaces zerobind 1 # always bind to all interfaces. Cookie support: No Default: zerobind 0 This is a compatiblity option for unix systems that don't support listening for connections on only one interface. If you have a BSD system, or muddleftpd is refusing to bind to the ports you specify, set zerobind and smartbind (see 1.1.2.53) to 1. 1.2 Misc references 1.2.1 Access modes [MODE] The directives that specify permissions for users when they access files are: access (see 1.1.2.1) fnaccess (see 1.1.2.21) pfnaccess (see 1.1.2.43) These require a mode string to specify what permissions a user has when a particular access line is matched. A mode string is a combination of one or more charaters, or: ALL - give all access permissions NONE - give no access permissions Letters that may make up a mode string: A - Create new filenames that don't already exist. R - Read files that already exist. L - List files (only for directories) X - Replace files that already exist. M - Create new directories. I - Remove existing directories. W - Write to existing files. H - Chmod existing files. C - allow to change to that directory. By combining these letters, any access level can be set. 1.2.2 Cookies in group sections. In group sections, cookies allow you to customize how information from the authentication module and the server is used to generate information about a new users session. Most commands valid in group sections support the use of these cookies: %U - The username the user gave the server. %v - The section name of the virtual server the user is logged into. Set to "main" if no virtual servers are defined. %V - The hostname of the virtual server the user is logged into. If no virtual servers are defined, this is set the the hostname provided by the main section, or by the machines hostname. %u - The uid of the user from the authentication module. %g - The gid of the user from the authentication module. %h - The home directory of the user from the authentication module. %r - The root directory of the user from the authentication module. %G - A comma delimited list of supplementary gids from the authentication module. Depending on the particular authentication module used, one or more of these cookies may not be set. See 2.0 for more information on authentication modules and what cookies are set by each individual one. Group directives where group section cookies are not supported: busydumpdata, byteratios, cddumpdata, fileratios, include, initalbytes, initalfiles, ipacl, maxusers, nameacl, quitdumpdata, ratiofile, welcomdumpdata. Group directives where group section cookies are avaliable, but only cookies not derived from the authentication module. authuser, and any directives which are used by the authentication module currently selected. 1.2.3 Specifing a string for busydumpdata, cddumpdata, welcomedumpdata and quitdumpdata. To use these directives, a string must be specified on a single line describing what to dump onto the screen. To get over the limitation, you can use control characters to perform tabs, insert spaces, and move to the next line. Note that all the control characters are specified with a / prefix, not a \. All uses of \ result in the following character being quoted exactly before the / are resolved: eg: \/\n is the same as /n and will be resolved to a newline. Control characters that are valid are: /n - Goto the next line. /s - Insert a space. You need this if you need spaces at the beginning or end of the directive. /t - Insert a tab. // - Insert a regular forward slash The strings specified for the dumpdata directives may also contain cookies specified in 1.2.4. Examples: cddumpdata You are now in %C/nYou have %a credits left would result in the following output (for chdir /) 250-You are now in / You have 1000000 credits left 250 "/" is the current directory. busydumpdata /s/s/sThe server is full./n Please try again later/nBye! would result in the following output (on login to a full group) 421- The server is full. Please try again later Bye! 421 Too many users. Cannot login. 1.2.4 Cookies in dumped files. When you specify a file to be dumped onto the screen, or set a string to be dumped on the screen, the following cookies can be inserted into that string or file to use information the server has internally: %T - current date and time %U - username of the user connecting. set to before login. %C - Current working directory, relitive to a user's root directory. Only avaliable after user is logged in. %E - The email address set in the configuration file. (See 1.1.2.14 for more info) %M - The maximum number of users that may exist in the current virtual server the user is connected to, or main server (before login) or maxiumun number of users a group can allow in. %N - The number of users currently in a group just after the user has logged in. It is not set before login. %L - The hostname of the server. Can be overridden. (see 1.1.2.28 for more information) %R - The hostname of the client obtained by reverse host lookup. %f - The number of files a user has downloaded. %F - The number of files a user has uploaded. %b - The number of bytes the user has downloaded in file transfers. %B - The number of bytes the user has uploaded in file transfers. %I - The number of bytes the user has downloaded in listings. %i - The number of listings the user has performed. %D - The total number of bytes the user has downloaded over data connections. %t - The total number of bytes the user has transfered over data connections (both upload and downloads) %c - The total number of data transfers the user has made. (for listing, downloads and uploads) %d - The total number of data transfers the user has made for downloading (listing and downloading) %v - The section name of the virtual server the user is connected to (or main if no virtual servers are declared) If the user is using ratios, the following are also avaliable. %a - The number of download byte credits a user has. %A - The number of download file credits a user has. 2.0 Authentication modules 2.0.1 Overview. Muddleftpd uses authentication modules to determine the following: - whether a user will be authenticated within a particular group. - is the username and password the user supplied correct. - what parameters are associated with that user (home directory, uid, gid, ...) Authentication modules under muddleftpd come in two flavours: - Static modules. These modules are already compiled into muddleftpd and can be accessed using a keyword for the authmethod. These modules are documented in 2.1 - Dynamic modules. These modules are not built with muddleftpd, but are dynamicly linked in while muddleftpd is authenticating an user. These are distributed separately from muddleftpd, and don't require muddleftpd to be recompiled to use. They can even be added while muddleftpd is still running. All modules are able to probe the configuration file for settings. They will often add several configuration options of their own, and the following cookies will work on them: %U - The username the user gave the server. %v - The section name of the virtual server the user is logged into. Set to "main" if no virtual servers are defined. %V - The hostname of the virtual server the user is logged into. If no virtual servers are defined, this is set the the hostname provided by the main section, or by the machines hostname. When a module has finished, the following cookies may be used on other options (see 1.2.2 for more info). Each individual module may or may provide information to set the following cookies: %u - The uid of the user. %g - The gid of the user. %h - The home directory of the user. %r - The root directory of the user. %G - A comma delimited list of supplementary gids for the user. You must check the documentation for the particular module you are going to use as to whether these options are set. 2.1 Static modules in muddleftpd The following modules are compiled into muddleftpd. 2.1.1 "unix" authentication module. This authentication module authenticates using the unix system passwords. It will automaticly detect shadow passwords and use them. It fully supports account and password expiry with shadow passwords. It requires root access to authenticate against shadow password files. To use this module in a group section, set the following directive: authmethod unix The following options may also be set in the same group section to configure the "unix" module: unix_passwdtype This forces what type of passwords are used by the module. If set to normal, shadow passwords will never be used. If set to shadow, normal passwords will never be acceped. All cookies described in 2.0 are set by the unix authentication module. The unix module will affect group selection by accepting any user found in the password file and authenticated them. If the user is not found in the password file, authentication will continue to the next group. Note: If muddleftpd is compiled when shadow passwords are not installed, and you wish to use shadow passwords, you will need to compile muddleftpd again after installing shadow passwords to enable the use of shadow passwords. 2.1.2 "anonymous" authentication module. The anonymous authentication module will authenticate users for anonymous access to the server. It will accept any username, using any password. It will log the password the user uses. The usernames this module will accept can be limited using the nameacl directive (see 1.1.2.41). Any users authenticated by this module will access files as user nobody in group nogroup. The module will set the users root directory to the home directory of the user "ftp". The users home directory will be set to /. To use this module in a group section, set the following directive: authmethod anonymous These directives can be used to tune the anonymous module: anonymous_user This changes the user muddleftpd probes to determine the root directory for the anonymous user. By default it is the user "ftp" This module will set all cookies described in 2.0 except for the suplementary groups cookie(%G) This module affects group selection by accepting all usernames presented to the module. You can limit what usernames it accepts by using the nameacl directive. However, if the username specified in anonymous_user (or "ftp" if anonymous_user isn't specified) cannot be read the module will cancel authentication. 2.1.3 "internal" authentication module. This module will use a separate password file in muddleftpd's own format to authenticate users. It is designed to provide password protection for authentication when users don't need an associated uid/gid. The password file consistes of one or more lines with the following format, one user per line. :: eg: rugger NvAdfesdaesEr:/home/rugger/:/ These password files may be modified using the external program mudpasswd. See mudpasswd.txt for more information on this program. To use the internal module, set the following directive in the relevent group section: authmethod internal The following directives may be set to configure the internal password module: internal_passfile This sets the path to the password file that the internal authentication module will read passwords and user info from. This file must be owned by the user running the server and must not be group or world writable, otherwise the module will refuse to use it. The internal authentication module will set the root directory (%r) and home directory (%h) cookies only. This module affects group selection by accepting any usernames defined in the given password file. If it isn't defined in the password file, the user is then passed onto the next group. If the password file cannot be loaded, or the password file is not safe, then authentication of the user is cancelled. Note: If the users in the separate password file map to the users in the main password file, and you want each user to use their own uid, you can set: uid %U to accomplish this. 2.1.4 "disabled" authentication module This built in module will cancel the authentication of anyone passed to the module. You need to use nameacl to restrict what usernames get canceled by this module. To use the disabled module in a group, use the following directive in that group: authmethod disabled This module does not set any of the cookies described in 2.0.1 This module affects group selection by canceling any username it is allowed to authenticate. 2.1.5 "pam" authentication module. This module allows muddleftpd to authenticate using PAM and PAM modules. This module also uses the password file to determine the session information the user will have. PAM is useful for systems where password encryption is not provided by regular crypt. To use the pam module, set the following directive in the relevent group sections: authmethod pam 3.0 FTP commands. 3.1 Non-site commands.muddleftpd-1.3.13.1/examples/0040755000175000017500000000000007751444665014730 5ustar joergjoergmuddleftpd-1.3.13.1/examples/mudlogd.conf0100644000175000017500000000033107544536576017227 0ustar joergjoerg # this is an example configuration of mudlogd [section] logger # log to /var/log/muddleftpd.log logfile /var/log/muddleftpd.log # communicate to muddleftpd using this fifoname /etc/muddleftpd/muddleftpd.fifo muddleftpd-1.3.13.1/examples/README0100644000175000017500000000255007544536576015612 0ustar joergjoergMUDDLEFTPD EXAMPLE CONFIGURATIONS There are a couple of example configurations included in this directory: standard.conf : This file contains a usable configuration for muddleftpd. It is very similar to the setup of an original system, and prevents root logins. It is a good place to start when configuring your system. It locks users into their home dir too. anon-only.conf : This file contains an anonymous only setup that does not allow user logins. If you want to set such a server up, this is a good place to start. It maps all usernames to the anonymous user. anon-region.conf : This configuration demonstrates how to set up muddleftpd to choose a group for a user given the host they arrived from. vserver.conf : This configuration shows how vservers are configured in muddleftpd. vserverbig.conf : This is a configuration that shows muddleftpd using 150 virtual servers, and the include directive. It actually runs fine on my computer. ratios.conf : This is showing how a theoretical mp3 server could be set up, showing off the latest features muddleftpd offers, like ratios, download speed limiters, and advanced ACL's verser-host.conf : This demonstrates the new single ip based virtual server setup. mudlogd.conf : This configuration is an example for the mudlogd program. muddleftpd-1.3.13.1/examples/anon-only.conf0100644000175000017500000000403507544536576017513 0ustar joergjoerg#---------------------------------------------------------- # This is the main server configuration [section] main # allow connections from port 21 ftpport 21 # set maximum users to 200 maxusers 200 # log everything execpt debugging logs logstrength 63 # set logfile logfile /var/log/anon-ftpd.log # set default timeout to 300 seconds timeout 300 # set the file displayed on login logindump /etc/issue.ftp # allow anyhost to connect ipacl A:* # set admin email address email user@hostname # set groups to run through.

(authlibmsql) Version 0.1 This module allows muddleftpd 1.3.4 and above authenticate using a mSQL server. This module will read client information from a supplied table/database within mSQL. It does not modify any data on the server. It supports: * Password encryption: Passwords can be encrypted on the mSQL server in either plaintext (no encryption) or crypt based methods. * Support for custom SELECT query strings. This allows tremendous flexibility for choosing the structure of the tables muddleftpd retreive data from. Note: This server is based very heavily off the mysql authentication module. Please excuse any reference to mysql I may make here as most of this module is copied directly from the mysql module. DEPENDANCIES: mSQL 2.0.11 or better. This module may compile and work on earlier versions, but it hasn't been tested for any older version. Unless you specify a custom query for authlibmsql to perform, the table containing user data must have the following fields, with these names: username The username password The password for the username homedir The home directory for the user. rootdir The root directory for the user. uid The uid of the user. gid The gid of the user. BUILDING: To build, execute the following in the authlibmsql source directory: ./configure [--with-msql=] make Or simply build it with the rest of muddleftpd, add --with-authmsql to the configuration options of that configure script. If mSQL is not installed in the default location (/usr/local/Hughes), you need to supply the --with-msql option with the path to the base directory of your mSQL setup. After you have run make, the file libauthmsql.so can be copied to the directory you wish to store muddleftpd modules in. This directory must be secure, so users cannot overwrite the module with a cracked version. By default it is put into @prefix@/lib from configure, if you dont set prefix this is /usr/local/lib/muddleftpd. USAGE: In the groups that you wish authlibmsql to authenticate, you need to use the following to tell muddleftpd to use the authlibmsql module, replacing the directory here with the directory the authentication module is stored in: (If unsure a locate libauthmsql.so may help). authmethod /usr/local/lib/muddleftpd/libauthmsql.so To configure authlibmsql, the following directives have been added. You must specify these in the group section that is being configured. msql_host This specifies the host the mSQL server is located on. If you do not specify this value, authlibmsql will assume the host is 'localhost'. (the same computer as the ftp server) msql_port This specifies what TCP port number to connect to the mSQL server using. If it is not supplied, the default mSQL port is used. msql_database This specifies what database to use on the mSQL server. It is advisable not to use the master database. You must specify this value for authlibmsql to work. msql_table This specifies the table to read user password data from. By default, this is 'users'. This is not used if you specify a custom query string. msql_encryption This specifies the type of encryption to use on passwords. There are two options avaliable: a) 'plaintext' Passwords are stored with no encryption at all. Anybody with read access to the database can steal the passwords. You should set muddleftpd.conf to 600 permissions if you use this setting. b) 'crypt' Use the standard unix crypt() call to test passwords, so they typically end up as the same format as the password file The default option for msql_encryption is 'crypt' msql_query (ADVANCED OPTION) This specifies the query to use to get data from the database. It should be a SELECT query that returns data in the following order: 1) password: The password of the user, in the selected encrypted form. 2) home directory: The home directory of the user. 3) root directory: The root directory of the user. 4) uid: An integer value for the user's uid. 5) gid: An integer value for the user's gid. This SELECT query should only return 1 result if the user exists, or no results if the user does not exist. You can use this option if the field names do not match the ones documented above. An example (must be entered on a single line in the config file): mysql_query SELECT pass,home,root,useruid,usergid FROM usertable WHERE user='%U' You can also use this option if data is spread among multiple tables. Another example (must still be on a single line in the config file!): mysql_query SELECT P.pass,C.home,C.root,C.uid,C.gid FROM passwd P, credtable C WHERE P.user=C.user AND P.user='%U' This gets data from the password table, and joins it with data from the credentials table to provide data for authlibmsql. GROUP EFFECTS: If authlibmsql finds a single result for a query, and the data checks out ok, then it will accept the username, and authenticate for it. If it finds no result for the query, then it will pass the username onto the next group section. If more than one result is returned, or an error occured along the way, authlibmsql will cancel authentication for that user. FURTHER NOTES: * You should avoid using plaintext stored passwords, especially since anyone who can read the configuration file can steal all the passwords in the mSQL database.

(authlibmud) Version 0.1 This module allows muddleftpd 1.3.4 and above authenticate against player files on a mud server. Note: This module is designed to run on a non-root execution of muddleftpd. It does not provide uid, gid information about a user. Note: This module does not provide any information other than the success of authenticating a user. No home or root directory information is passed on. You will need to configure these things in the config file. Note: You may need to modify the code to get this to work on your mud. YMMV. Contact me if you have any difficulties. DEPENDANCIES: None. However this module is useless unless you are using muddleftpd 1.3.4 or better. Without modifing the code, authlibmud assumes: * People level 21 and above are wizards and can login. * Passwords in the player files are encrypted using the unix crypt() call. * The fields for the level and password in the player file are labeled "Level" and "Password" in the same order. BUILDING: To build, execute the following in the authlibmud source directory: ./configure make Or simply build it with the rest of muddleftpd, add --with-authmud to the configuration options of that configure script. Then the file libauthmud.so can be copied to the directory you with to store muddleftpd modules in. This directory must be secure, so users cannot overwrite the module with a cracked version. By default it is put into @prefix@/lib from configure, if you dont set prefix this is /usr/local/lib/muddleftpd. USAGE: In the groups that you wish authlibmud to authenticate, you need to use the following to tell muddleftpd to use the authlibmud module, replacing the directory with the directory the authentication module is stored in: (If unsure a locate libauthmud.so may help). authmethod /usr/local/lib/muddleftpd/libauthmud.so To configure libauthmud, the following directives have been added. You must specify these in the group section that is being configured. playerfile This is the path and filename of the user filename. You should construct this using the %U token, so it changes depending on who is logging in. For example if player files are stored in /usr/local/mud/players//.passwd then you would use in the config file: playerfile /usr/local/mud/players/%(0,0)U/%U.passwd GROUP EFFECTS: If the player file is found, and the player has a level greater than 20, then authlibmud will accept the username and authenticate for it. If the player file is found, but the player has a level less than or equal to 20, then authentication is cancelled. If the player file is not found, authlibmud will pass the username to the next group section.

(authlibmysql) Version 0.1 This module allows muddleftpd 1.3.4 and above authenticate using a MySQL server. This module will read client information from a supplied table/database within MySQL. It does not modify any data on the server. It supports: * Password encryption: Passwords can be encrypted on the MySQL server in either plaintext (no encryption), crypt based, or the portable mysql password format. * Support for custom SELECT query strings. This allows tremendous flexibility for choosing the structure of the tables muddleftpd retreive data from. DEPENDANCIES: MySQL 3.22.32 or better. This module may compile and work on earlier versions, but it hasn't been tested for any older version. Unless you specify a custom query for authlibmysql to perform, the table containing user data must have the following fields, with these names: username The username password The password for the username homedir The home directory for the user. rootdir The root directory for the user. uid The uid of the user. gid The gid of the user. BUILDING: To build, execute the following in the authlibmysql source directory: ./configure [--with-mysql=] make Or simply build it with the rest of muddleftpd, add --with-authmysql to the configuration options of that configure script. When you have run make, the file libauthmysql.so can be copied to the directory you wish to store muddleftpd modules in. This directory must be secure, so users cannot overwrite the module with a cracked version. By default it is put into @prefix@/lib from configure, if you dont set prefix this is /usr/local/lib/muddleftpd. USAGE: In the groups that you wish authlibmysql to authenticate, you need to use the following to tell muddleftpd to use the authlibmysql module, replacing the directory here with the directory the authentication module is stored in: (If unsure a locate libauthmysql.so may help). authmethod /usr/local/lib/muddleftpd/libauthmysql.so To configure authlibmysql, the following directives have been added. You must specify these in the group section that is being configured. mysql_host This specifies the host the MySQL server is located on. If you do not specify this value, authlibmysql will assume the host is 'localhost'. (the same computer as the ftp server) mysql_port This specifies what TCP port number to connect to the MySQL server using. If it is not supplied, the default MySQL port is used. mysql_database This specifies what database to use on the MySQL server. It is advisable not to use the master database. You must specify this value for authlibmysql to work. mysql_user This specifies the username to access the MySQL server as. This user should only require read access. You must specify this value, otherwise authlibmysql will refuse to work. mysql_password This specifies the password paired to the username used to access the MySQL server. You must specify this value. mysql_table This specifies the table to read user password data from. By default, this is 'users'. This is not used if you specify a custom query string. mysql_encryption This specifies the type of encryption to use on passwords. There are three options avaliable: a) 'plaintext' Passwords are stored with no encryption at all. Anybody with read access to the database can steal the passwords. You should set muddleftpd.conf to 600 permissions if you use this setting. b) 'crypt' Use the standard unix crypt() call to test passwords, so they typically end up as the same format as the password file c) 'mysql' Use MySQL's builtin function password() to test passwords. This is portable, and is easy to use within MySQL scripts. The default option for mysql_encryption is 'mysql' mysql_query (ADVANCED OPTION) This specifies the query to use to get data from the database. It should be a SELECT query that returns data in the following order: 1) password: The password of the user, in the selected encrypted form. 2) home directory: The home directory of the user. 3) root directory: The root directory of the user. 4) uid: An integer value for the user's uid. 5) gid: An integer value for the user's gid. This SELECT query should only return 1 result if the user exists, or no results if the user does not exist. You can use this option if the field names do not match the ones documented above. An example (must be entered on a single line in the config file): mysql_query SELECT pass,home,root,useruid,usergid FROM usertable WHERE user='%U' You can also use this option if data is spread among multiple tables. Another example (must still be on a single line in the config file!): mysql_query SELECT P.pass,C.home,C.root,C.uid,C.gid FROM passwd P, credtable C WHERE P.user=C.user AND P.user='%U' This gets data from the password table, and joins it with data from the credentials table to provide data for authlibmysql. GROUP EFFECTS: If authlibmysql finds a single result for a query, and the data checks out ok, then it will accept the username, and authenticate for it. If it finds no result for the query, then it will pass the username onto the next group section. If more than one result is returned, or an error occured along the way, authlibmysql will cancel authentication for that user. FURTHER NOTES: * You should avoid using plaintext stored passwords, especially since anyone who can read the configuration file can steal all the passwords in the MySQL database.

(authlibsmb) Version 0.1 This module allows muddleftpd 1.3.4 and above authenticate against SMB servers. This module will authenticate against the user list on any SMB domain server, including both windows NT and Samba. Note: This code is heavily dirived from the smb pam module. It is essentually a front end for the smb pam module backend. Kudos to the maintainers smb pam module for the good work. Note: Although this code is dirived from the smb pam module, It does not require pam to operate. DEPENDANCIES: A smb server somewhere available. Also, authlibsmb requires that each user you wish to authenticate has a local password entry. (unless you use the smb_localuser directive, where all smb users use the same local username) BUILDING: To build, execute the following in the authlibsmb source directory: ./configure make Or simply build it with the rest of muddleftpd, add --with-authsmb to the configuration options of that configure script. Then the file libauthsmb.so can be copied to the directory you with to store muddleftpd modules in. This directory must be secure, so users cannot overwrite the module with a cracked version. By default it is put into @prefix@/lib from configure, if you dont set prefix this is /usr/local/lib/muddleftpd. USAGE: In the groups that you wish authlibsmb to authenticate, you need to use the following to tell muddleftpd to use the authlibsmb module, replacing the directory with the directory the authentication module is stored in: (If unsure a locate libauthsmb.so may help). authmodule /usr/local/lib/muddleftpd/libauthsmb.so To configure libauthsmb, the following directives have been added. You must specify these in the group section that is being configured. smb_domain This specifies is the domain/workgroup that contains the domain server to authenticate against. THIS PARAMTER IS REQUIRED smb_primary This specifies the netbios name of the domain server, that is used to authenticate against. THIS PARAMETER IS REQUIRED smb_secondary This specifies the netbios name of the secondary domain server, that is used to authenticate against. THIS PARAMETER IS OPTIONAL smb_localuser This specifies the local user on the system (from the password file) that smb users will access the system ass. If omitted, authlibsmb will use the login username. GROUP EFFECTS: If smb_localuser is specified, authlibsmb will accept any username given to it, regardless of whether or not it exists on the SMB server. This does not mean it will log the user in, it will simply not pass the username onto the next group section. You will have to use nameacl to limit this if required. If smb_localuser is not specified, authlibsmb will only accept usernames that also exist in the local password file. Users not found in the local password file will be passed onto the next muddleftpd group section. FURTHER NOTES: * authlibsmb cannot detect the difference between a username not existing on a domain server and the password being incorrect.

In fact, it is a very slow implementation This code is NOT a complete DES implementation. It implements only the minimum necessary for SMB authentication, as used by all SMB products (including every copy of Microsoft Windows95 ever sold) In particular, it can only do a unchained forward DES pass. This means it is not possible to use this code for encryption/decryption of data, instead it is only useful as a "hash" algorithm. There is no entry point into this code that allows normal DES operation. I believe this means that this code does not come under ITAR regulations but this is NOT a legal opinion. If you are concerned about the applicability of ITAR regulations to this code then you should confirm it for yourself (and maybe let me know if you come up with a different answer to the one above) */ static int perm1[56] = {57, 49, 41, 33, 25, 17, 9, 1, 58, 50, 42, 34, 26, 18, 10, 2, 59, 51, 43, 35, 27, 19, 11, 3, 60, 52, 44, 36, 63, 55, 47, 39, 31, 23, 15, 7, 62, 54, 46, 38, 30, 22, 14, 6, 61, 53, 45, 37, 29, 21, 13, 5, 28, 20, 12, 4}; static int perm2[48] = {14, 17, 11, 24, 1, 5, 3, 28, 15, 6, 21, 10, 23, 19, 12, 4, 26, 8, 16, 7, 27, 20, 13, 2, 41, 52, 31, 37, 47, 55, 30, 40, 51, 45, 33, 48, 44, 49, 39, 56, 34, 53, 46, 42, 50, 36, 29, 32}; static int perm3[64] = {58, 50, 42, 34, 26, 18, 10, 2, 60, 52, 44, 36, 28, 20, 12, 4, 62, 54, 46, 38, 30, 22, 14, 6, 64, 56, 48, 40, 32, 24, 16, 8, 57, 49, 41, 33, 25, 17, 9, 1, 59, 51, 43, 35, 27, 19, 11, 3, 61, 53, 45, 37, 29, 21, 13, 5, 63, 55, 47, 39, 31, 23, 15, 7}; static int perm4[48] = { 32, 1, 2, 3, 4, 5, 4, 5, 6, 7, 8, 9, 8, 9, 10, 11, 12, 13, 12, 13, 14, 15, 16, 17, 16, 17, 18, 19, 20, 21, 20, 21, 22, 23, 24, 25, 24, 25, 26, 27, 28, 29, 28, 29, 30, 31, 32, 1}; static int perm5[32] = { 16, 7, 20, 21, 29, 12, 28, 17, 1, 15, 23, 26, 5, 18, 31, 10, 2, 8, 24, 14, 32, 27, 3, 9, 19, 13, 30, 6, 22, 11, 4, 25}; static int perm6[64] ={ 40, 8, 48, 16, 56, 24, 64, 32, 39, 7, 47, 15, 55, 23, 63, 31, 38, 6, 46, 14, 54, 22, 62, 30, 37, 5, 45, 13, 53, 21, 61, 29, 36, 4, 44, 12, 52, 20, 60, 28, 35, 3, 43, 11, 51, 19, 59, 27, 34, 2, 42, 10, 50, 18, 58, 26, 33, 1, 41, 9, 49, 17, 57, 25}; static int sc[16] = {1, 1, 2, 2, 2, 2, 2, 2, 1, 2, 2, 2, 2, 2, 2, 1}; static int sbox[8][4][16] = { {{14, 4, 13, 1, 2, 15, 11, 8, 3, 10, 6, 12, 5, 9, 0, 7}, {0, 15, 7, 4, 14, 2, 13, 1, 10, 6, 12, 11, 9, 5, 3, 8}, {4, 1, 14, 8, 13, 6, 2, 11, 15, 12, 9, 7, 3, 10, 5, 0}, {15, 12, 8, 2, 4, 9, 1, 7, 5, 11, 3, 14, 10, 0, 6, 13}}, {{15, 1, 8, 14, 6, 11, 3, 4, 9, 7, 2, 13, 12, 0, 5, 10}, {3, 13, 4, 7, 15, 2, 8, 14, 12, 0, 1, 10, 6, 9, 11, 5}, {0, 14, 7, 11, 10, 4, 13, 1, 5, 8, 12, 6, 9, 3, 2, 15}, {13, 8, 10, 1, 3, 15, 4, 2, 11, 6, 7, 12, 0, 5, 14, 9}}, {{10, 0, 9, 14, 6, 3, 15, 5, 1, 13, 12, 7, 11, 4, 2, 8}, {13, 7, 0, 9, 3, 4, 6, 10, 2, 8, 5, 14, 12, 11, 15, 1}, {13, 6, 4, 9, 8, 15, 3, 0, 11, 1, 2, 12, 5, 10, 14, 7}, {1, 10, 13, 0, 6, 9, 8, 7, 4, 15, 14, 3, 11, 5, 2, 12}}, {{7, 13, 14, 3, 0, 6, 9, 10, 1, 2, 8, 5, 11, 12, 4, 15}, {13, 8, 11, 5, 6, 15, 0, 3, 4, 7, 2, 12, 1, 10, 14, 9}, {10, 6, 9, 0, 12, 11, 7, 13, 15, 1, 3, 14, 5, 2, 8, 4}, {3, 15, 0, 6, 10, 1, 13, 8, 9, 4, 5, 11, 12, 7, 2, 14}}, {{2, 12, 4, 1, 7, 10, 11, 6, 8, 5, 3, 15, 13, 0, 14, 9}, {14, 11, 2, 12, 4, 7, 13, 1, 5, 0, 15, 10, 3, 9, 8, 6}, {4, 2, 1, 11, 10, 13, 7, 8, 15, 9, 12, 5, 6, 3, 0, 14}, {11, 8, 12, 7, 1, 14, 2, 13, 6, 15, 0, 9, 10, 4, 5, 3}}, {{12, 1, 10, 15, 9, 2, 6, 8, 0, 13, 3, 4, 14, 7, 5, 11}, {10, 15, 4, 2, 7, 12, 9, 5, 6, 1, 13, 14, 0, 11, 3, 8}, {9, 14, 15, 5, 2, 8, 12, 3, 7, 0, 4, 10, 1, 13, 11, 6}, {4, 3, 2, 12, 9, 5, 15, 10, 11, 14, 1, 7, 6, 0, 8, 13}}, {{4, 11, 2, 14, 15, 0, 8, 13, 3, 12, 9, 7, 5, 10, 6, 1}, {13, 0, 11, 7, 4, 9, 1, 10, 14, 3, 5, 12, 2, 15, 8, 6}, {1, 4, 11, 13, 12, 3, 7, 14, 10, 15, 6, 8, 0, 5, 9, 2}, {6, 11, 13, 8, 1, 4, 10, 7, 9, 5, 0, 15, 14, 2, 3, 12}}, {{13, 2, 8, 4, 6, 15, 11, 1, 10, 9, 3, 14, 5, 0, 12, 7}, {1, 15, 13, 8, 10, 3, 7, 4, 12, 5, 6, 11, 0, 14, 9, 2}, {7, 11, 4, 1, 9, 12, 14, 2, 0, 6, 10, 13, 15, 3, 5, 8}, {2, 1, 14, 7, 4, 10, 8, 13, 15, 12, 9, 0, 3, 5, 6, 11}}}; static void permute(char *out, char *in, int *p, int n) { int i; for (i=0;i>1; key[1] = ((str[0]&0x01)<<6) | (str[1]>>2); key[2] = ((str[1]&0x03)<<5) | (str[2]>>3); key[3] = ((str[2]&0x07)<<4) | (str[3]>>4); key[4] = ((str[3]&0x0F)<<3) | (str[4]>>5); key[5] = ((str[4]&0x1F)<<2) | (str[5]>>6); key[6] = ((str[5]&0x3F)<<1) | (str[6]>>7); key[7] = str[6]&0x7F; for (i=0;i<8;i++) { key[i] = (key[i]<<1); } } static void smbhash(unsigned char *out, unsigned char *in, unsigned char *key) { int i; char outb[64]; char inb[64]; char keyb[64]; unsigned char key2[8]; str_to_key(key, key2); for (i=0;i<64;i++) { inb[i] = (in[i/8] & (1<<(7-(i%8)))) ?

This sort of thing is always nasty do deal with. Note that * the version here does not include floating point... * * snprintf() is used instead of sprintf() as it does limit checks * for string length. This covers a nasty loophole. * * The other functions are there to prevent NULL pointers from * causing nast effects. * * More Recently: * Brandon Long 9/15/96 for mutt 0.43 * This was ugly. It is still ugly. I opted out of floating point * numbers, but the formatter understands just about everything * from the normal C string format, at least as far as I can tell from * the Solaris 2.5 printf(3S) man page. * * Brandon Long 10/22/97 for mutt 0.87.1 * Ok, added some minimal floating point support, which means this * probably requires libm on most operating systems. Don't yet * support the exponent (e,E) and sigfig (g,G). Also, fmtint() * was pretty badly broken, it just wasn't being exercised in ways * which showed it, so that's been fixed. Also, formated the code * to mutt conventions, and removed dead code left over from the * original. Also, there is now a builtin-test, just compile with: * gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm * and run snprintf for results. * * Thomas Roessler 01/27/98 for mutt 0.89i * The PGP code was using unsigned hexadecimal formats. * Unfortunately, unsigned formats simply didn't work. * * Michael Elkins 03/05/98 for mutt 0.90.8 * The original code assumed that both snprintf() and vsnprintf() were * missing. Some systems only have snprintf() but not vsnprintf(), so * the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF. * * Andrew Tridgell (tridge@samba.org) Oct 1998 * fixed handling of %.0f * added test for HAVE_LONG_DOUBLE * **************************************************************/ #include "../../config.h" #include # include #include #ifndef INT_MAX #define INT_MAX 0x7FFFFFFF #endif #if !defined(HAVE_SNPRINTF) || !defined(HAVE_VSNPRINTF) /* Define this as a fall through, HAVE_STDARG_H is probably already set */ #define HAVE_VARARGS_H /* varargs declarations: */ #if defined(HAVE_STDARG_H) # include # define HAVE_STDARGS /* let's hope that works everywhere (mj) */ # define VA_LOCAL_DECL va_list ap # define VA_START(f) va_start(ap, f) # define VA_SHIFT(v,t) ; /* no-op for ANSI */ # define VA_END va_end(ap) #else # if defined(HAVE_VARARGS_H) # include # undef HAVE_STDARGS # define VA_LOCAL_DECL va_list ap # define VA_START(f) va_start(ap) /* f is ignored! */ # define VA_SHIFT(v,t) v = va_arg(ap,t) # define VA_END va_end(ap) # else /*XX ** NO VARARGS ** XX*/ # endif #endif #ifdef HAVE_LONG_DOUBLE #define LDOUBLE long double #else #define LDOUBLE double #endif /*int snprintf (char *str, size_t count, const char *fmt, ...);*/ /*int vsnprintf (char *str, size_t count, const char *fmt, va_list arg);*/ static int dopr (char *buffer, size_t maxlen, const char *format, va_list args); static void fmtstr (char *buffer, size_t *currlen, size_t maxlen, size_t *reallen, char *value, int flags, int min, int max); static void fmtint (char *buffer, size_t *currlen, size_t maxlen, size_t *reallen, long value, int base, int min, int max, int flags); static void fmtfp (char *buffer, size_t *currlen, size_t maxlen, size_t *reallen, LDOUBLE fvalue, int min, int max, int flags); static void dopr_outch (char *buffer, size_t *currlen, size_t maxlen, size_t *reallen, char c ); /* * dopr(): poor man's version of doprintf */ /* format read states */ #define DP_S_DEFAULT 0 #define DP_S_FLAGS 1 #define DP_S_MIN 2 #define DP_S_DOT 3 #define DP_S_MAX 4 #define DP_S_MOD 5 #define DP_S_CONV 6 #define DP_S_DONE 7 /* format flags - Bits */ #define DP_F_MINUS (1 << 0) #define DP_F_PLUS (1 << 1) #define DP_F_SPACE (1 << 2) #define DP_F_NUM (1 << 3) #define DP_F_ZERO (1 << 4) #define DP_F_UP (1 << 5) #define DP_F_UNSIGNED (1 << 6) /* Conversion Flags */ #define DP_C_SHORT 1 #define DP_C_LONG 2 #define DP_C_LDOUBLE 3 #define char_to_int(p) (p - '0') #define MAX(p,q) ((p >= q) ?

Send questions/comments/complaints/performance data to dl@cs.oswego.edu * VERSION 2.6.6 Sun Mar 5 19:10:03 2000 Doug Lea (dl at gee) Note: There may be an updated version of this malloc obtainable at ftp://g.oswego.edu/pub/misc/malloc.c Check before installing! * Why use this malloc? This is not the fastest, most space-conserving, most portable, or most tunable malloc ever written. However it is among the fastest while also being among the most space-conserving, portable and tunable. Consistent balance across these factors results in a good general-purpose allocator. For a high-level description, see http://g.oswego.edu/dl/html/malloc.html * Synopsis of public routines (Much fuller descriptions are contained in the program documentation below.) malloc(size_t n); Return a pointer to a newly allocated chunk of at least n bytes, or null if no space is available. free(Void_t* p); Release the chunk of memory pointed to by p, or no effect if p is null. realloc(Void_t* p, size_t n); Return a pointer to a chunk of size n that contains the same data as does chunk p up to the minimum of (n, p's size) bytes, or null if no space is available. The returned pointer may or may not be the same as p. If p is null, equivalent to malloc. Unless the #define REALLOC_ZERO_BYTES_FREES below is set, realloc with a size argument of zero (re)allocates a minimum-sized chunk. memalign(size_t alignment, size_t n); Return a pointer to a newly allocated chunk of n bytes, aligned in accord with the alignment argument, which must be a power of two. valloc(size_t n); Equivalent to memalign(pagesize, n), where pagesize is the page size of the system (or as near to this as can be figured out from all the includes/defines below.) pvalloc(size_t n); Equivalent to valloc(minimum-page-that-holds(n)), that is, round up n to nearest pagesize. calloc(size_t unit, size_t quantity); Returns a pointer to quantity * unit bytes, with all locations set to zero. cfree(Void_t* p); Equivalent to free(p). malloc_trim(size_t pad); Release all but pad bytes of freed top-most memory back to the system. Return 1 if successful, else 0. malloc_usable_size(Void_t* p); Report the number usable allocated bytes associated with allocated chunk p. This may or may not report more bytes than were requested, due to alignment and minimum size constraints. malloc_stats(); Prints brief summary statistics on stderr. mallinfo() Returns (by copy) a struct containing various summary statistics. mallopt(int parameter_number, int parameter_value) Changes one of the tunable parameters described below. Returns 1 if successful in changing the parameter, else 0. * Vital statistics: Alignment: 8-byte 8 byte alignment is currently hardwired into the design. This seems to suffice for all current machines and C compilers. Assumed pointer representation: 4 or 8 bytes Code for 8-byte pointers is untested by me but has worked reliably by Wolfram Gloger, who contributed most of the changes supporting this. Assumed size_t representation: 4 or 8 bytes Note that size_t is allowed to be 4 bytes even if pointers are 8. Minimum overhead per allocated chunk: 4 or 8 bytes Each malloced chunk has a hidden overhead of 4 bytes holding size and status information. Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead) 8-byte ptrs: 24/32 bytes (including, 4/8 overhead) When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte ptrs but 4 byte size) or 24 (for 8/8) additional bytes are needed; 4 (8) for a trailing size field and 8 (16) bytes for free list pointers. Thus, the minimum allocatable size is 16/24/32 bytes. Even a request for zero bytes (i.e., malloc(0)) returns a pointer to something of the minimum allocatable size. Maximum allocated size: 4-byte size_t: 2^31 - 8 bytes 8-byte size_t: 2^63 - 16 bytes It is assumed that (possibly signed) size_t bit values suffice to represent chunk sizes. `Possibly signed' is due to the fact that `size_t' may be defined on a system as either a signed or an unsigned type. To be conservative, values that would appear as negative numbers are avoided. Requests for sizes with a negative sign bit when the request size is treaded as a long will return null. Maximum overhead wastage per allocated chunk: normally 15 bytes Alignnment demands, plus the minimum allocatable size restriction make the normal worst-case wastage 15 bytes (i.e., up to 15 more bytes will be allocated than were requested in malloc), with two exceptions: 1. Because requests for zero bytes allocate non-zero space, the worst case wastage for a request of zero bytes is 24 bytes. 2. For requests >= mmap_threshold that are serviced via mmap(), the worst case wastage is 8 bytes plus the remainder from a system page (the minimal mmap unit); typically 4096 bytes. * Limitations Here are some features that are NOT currently supported * No user-definable hooks for callbacks and the like. * No automated mechanism for fully checking that all accesses to malloced memory stay within their bounds. * No support for compaction. * Synopsis of compile-time options: People have reported using previous versions of this malloc on all versions of Unix, sometimes by tweaking some of the defines below. It has been tested most extensively on Solaris and Linux. It is also reported to work on WIN32 platforms. People have also reported adapting this malloc for use in stand-alone embedded systems. The implementation is in straight, hand-tuned ANSI C. Among other consequences, it uses a lot of macros. Because of this, to be at all usable, this code should be compiled using an optimizing compiler (for example gcc -O2) that can simplify expressions and control paths. __STD_C (default: derived from C compiler defines) Nonzero if using ANSI-standard C compiler, a C++ compiler, or a C compiler sufficiently close to ANSI to get away with it. DEBUG (default: NOT defined) Define to enable debugging. Adds fairly extensive assertion-based checking to help track down memory errors, but noticeably slows down execution. REALLOC_ZERO_BYTES_FREES (default: NOT defined) Define this if you think that realloc(p, 0) should be equivalent to free(p). Otherwise, since malloc returns a unique pointer for malloc(0), so does realloc(p, 0). HAVE_MEMCPY (default: defined) Define if you are not otherwise using ANSI STD C, but still have memcpy and memset in your C library and want to use them. Otherwise, simple internal versions are supplied. USE_MEMCPY (default: 1 if HAVE_MEMCPY is defined, 0 otherwise) Define as 1 if you want the C library versions of memset and memcpy called in realloc and calloc (otherwise macro versions are used). At least on some platforms, the simple macro versions usually outperform libc versions. HAVE_MMAP (default: defined as 1) Define to non-zero to optionally make malloc() use mmap() to allocate very large blocks. HAVE_MREMAP (default: defined as 0 unless Linux libc set) Define to non-zero to optionally make realloc() use mremap() to reallocate very large blocks. malloc_getpagesize (default: derived from system #includes) Either a constant or routine call returning the system page size. HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined) Optionally define if you are on a system with a /usr/include/malloc.h that declares struct mallinfo. It is not at all necessary to define this even if you do, but will ensure consistency. INTERNAL_SIZE_T (default: size_t) Define to a 32-bit type (probably `unsigned int') if you are on a 64-bit machine, yet do not want or need to allow malloc requests of greater than 2^31 to be handled. This saves space, especially for very small chunks. INTERNAL_LINUX_C_LIB (default: NOT defined) Defined only when compiled as part of Linux libc. Also note that there is some odd internal name-mangling via defines (for example, internally, `malloc' is named `mALLOc') needed when compiling in this case. These look funny but don't otherwise affect anything. WIN32 (default: undefined) Define this on MS win (95, nt) platforms to compile in sbrk emulation. LACKS_UNISTD_H (default: undefined if not WIN32) Define this if your system does not have a . LACKS_SYS_PARAM_H (default: undefined if not WIN32) Define this if your system does not have a . MORECORE (default: sbrk) The name of the routine to call to obtain more memory from the system. MORECORE_FAILURE (default: -1) The value returned upon failure of MORECORE. MORECORE_CLEARS (default 1) True (1) if the routine mapped to MORECORE zeroes out memory (which holds for sbrk). DEFAULT_TRIM_THRESHOLD DEFAULT_TOP_PAD DEFAULT_MMAP_THRESHOLD DEFAULT_MMAP_MAX Default values of tunable parameters (described in detail below) controlling interaction with host system routines (sbrk, mmap, etc). These values may also be changed dynamically via mallopt(). The preset defaults are those that give best performance for typical programs/systems. USE_DL_PREFIX (default: undefined) Prefix all public routines with the string 'dl'. Useful to quickly avoid procedure declaration conflicts and linker symbol conflicts with existing memory allocation routines. */ /* Preliminaries */ #ifndef __STD_C #ifdef __STDC__ #define __STD_C 1 #else #if __cplusplus #define __STD_C 1 #else #define __STD_C 0 #endif /*__cplusplus*/ #endif /*__STDC__*/ #endif /*__STD_C*/ #ifndef Void_t #if (__STD_C || defined(WIN32)) #define Void_t void #else #define Void_t char #endif #endif /*Void_t*/ #if __STD_C #include /* for size_t */ #else #include #endif #ifdef __cplusplus extern "C" { #endif #include /* needed for malloc_stats */ /* Compile-time options */ /* Debugging: Because freed chunks may be overwritten with link fields, this malloc will often die when freed memory is overwritten by user programs.

The checking is fairly extensive, and will slow down execution noticeably.

The trim threshold and the mmap control parameters (see below) can be traded off with one another. Trimming and mmapping are two different ways of releasing unused memory back to the system. Between these two, it is often possible to keep system-level demands of a long-lived program down to a bare minimum. For example, in one test suite of sessions measuring the XF86 X server on Linux, using a trim threshold of 128K and a mmap threshold of 192K led to near-minimal long term resource consumption. If you are using this malloc in a long-lived program, it should pay to experiment with these values. As a rough guide, you might set to a value close to the average size of a process (program) running on your system. Releasing this much memory would allow such a process to run in memory. Generally, it's worth it to tune for trimming rather tham memory mapping when a program undergoes phases where several large chunks are allocated and released in ways that can reuse each other's storage, perhaps mixed with phases where there are no such chunks at all. And in well-behaved long-lived programs, controlling release of large blocks via trimming versus mapping is usually faster. However, in most programs, these parameters serve mainly as protection against the system-level effects of carrying around massive amounts of unneeded memory. Since frequent calls to sbrk, mmap, and munmap otherwise degrade performance, the default parameters are set to relatively high values that serve only as safeguards. The default trim value is high enough to cause trimming only in fairly extreme (by current memory consumption standards) cases. It must be greater than page size to have any useful effect. To disable trimming completely, you can set to (unsigned long)(-1); */ #ifndef DEFAULT_TOP_PAD #define DEFAULT_TOP_PAD (0) #endif /* M_TOP_PAD is the amount of extra `padding' space to allocate or retain whenever sbrk is called. It is used in two ways internally: * When sbrk is called to extend the top of the arena to satisfy a new malloc request, this much padding is added to the sbrk request. * When malloc_trim is called automatically from free(), it is used as the `pad' argument. In both cases, the actual amount of padding is rounded so that the end of the arena is always a system page boundary. The main reason for using padding is to avoid calling sbrk so often. Having even a small pad greatly reduces the likelihood that nearly every malloc request during program start-up (or after trimming) will invoke sbrk, which needlessly wastes time. Automatic rounding-up to page-size units is normally sufficient to avoid measurable overhead, so the default is 0. However, in systems where sbrk is relatively slow, it can pay to increase this value, at the expense of carrying around more memory than the program needs. */ #ifndef DEFAULT_MMAP_THRESHOLD #define DEFAULT_MMAP_THRESHOLD (128 * 1024) #endif /* M_MMAP_THRESHOLD is the request size threshold for using mmap() to service a request. Requests of at least this size that cannot be allocated using already-existing space will be serviced via mmap. (If enough normal freed space already exists it is used instead.) Using mmap segregates relatively large chunks of memory so that they can be individually obtained and released from the host system. A request serviced through mmap is never reused by any other request (at least not directly; the system may just so happen to remap successive requests to the same locations). Segregating space in this way has the benefit that mmapped space can ALWAYS be individually released back to the system, which helps keep the system level memory demands of a long-lived program low. Mapped memory can never become `locked' between other chunks, as can happen with normally allocated chunks, which menas that even trimming via malloc_trim would not release them. However, it has the disadvantages that: 1. The space cannot be reclaimed, consolidated, and then used to service later requests, as happens with normal chunks. 2. It can lead to more wastage because of mmap page alignment requirements 3. It causes malloc performance to be more dependent on host system memory management support routines which may vary in implementation quality and may impose arbitrary limitations. Generally, servicing a request via normal malloc steps is faster than going through a system's mmap. All together, these considerations should lead you to use mmap only for relatively large requests. */ #ifndef DEFAULT_MMAP_MAX #if HAVE_MMAP #define DEFAULT_MMAP_MAX (64) #else #define DEFAULT_MMAP_MAX (0) #endif #endif /* M_MMAP_MAX is the maximum number of requests to simultaneously service using mmap.

If a program allocates many large regions, it is probably better off using normal sbrk-based allocation routines that can reclaim and reallocate normal heap memory. Using a small value allows transition into this mode after the first few allocations. Setting to 0 disables all use of mmap. If HAVE_MMAP is not set, the default value is 0, and attempts to set it to non-zero values in mallopt will fail. */ /* USE_DL_PREFIX will prefix all public routines with the string 'dl'.

Chunks of memory are maintained using a `boundary tag' method as described in e.g., Knuth or Standish. (See the paper by Paul Wilson ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such techniques.) Sizes of free chunks are stored both in the front of each chunk and at the end. This makes consolidating fragmented chunks into bigger chunks very fast. The size fields also hold bits representing whether chunks are free or in use. An allocated chunk looks like this: chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of previous chunk, if allocated | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of chunk, in bytes |P| mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | User data starts here... . . . . (malloc_usable_space() bytes) . . | nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of chunk | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Where "chunk" is the front of the chunk for the purpose of most of the malloc code, but "mem" is the pointer that is returned to the user. "Nextchunk" is the beginning of the next contiguous chunk. Chunks always begin on even word boundries, so the mem portion (which is returned to the user) is also on an even word boundary, and thus double-word aligned. Free chunks are stored in circular doubly-linked lists, and look like this: chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Size of previous chunk | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ `head:' | Size of chunk, in bytes |P| mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Forward pointer to next chunk in list | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Back pointer to previous chunk in list | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Unused space (may be 0 bytes long) . . . . | nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ `foot:' | Size of chunk, in bytes | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ The P (PREV_INUSE) bit, stored in the unused low-order bit of the chunk size (which is always a multiple of two words), is an in-use bit for the *previous* chunk. If that bit is *clear*, then the word before the current chunk size contains the previous chunk size, and can be used to find the front of the previous chunk. (The very first chunk allocated always has this bit set, preventing access to non-existent (or non-owned) memory.) Note that the `foot' of the current chunk is actually represented as the prev_size of the NEXT chunk. (This makes it easier to deal with alignments etc). The two exceptions to all this are 1. The special chunk `top', which doesn't bother using the trailing size field since there is no next contiguous chunk that would have to index off it. (After initialization, `top' is forced to always exist. If it would become less than MINSIZE bytes long, it is replenished via malloc_extend_top.) 2. Chunks allocated via mmap, which have the second-lowest-order bit (IS_MMAPPED) set in their size fields. Because they are never merged or traversed from any other chunk, they have no foot size or inuse information. Available chunks are kept in any of several places (all declared below): * `av': An array of chunks serving as bin headers for consolidated chunks. Each bin is doubly linked. The bins are approximately proportionally (log) spaced. There are a lot of these bins (128). This may look excessive, but works very well in practice. All procedures maintain the invariant that no consolidated chunk physically borders another one. Chunks in bins are kept in size order, with ties going to the approximately least recently used chunk. The chunks in each bin are maintained in decreasing sorted order by size. This is irrelevant for the small bins, which all contain the same-sized chunks, but facilitates best-fit allocation for larger chunks. (These lists are just sequential. Keeping them in order almost never requires enough traversal to warrant using fancier ordered data structures.) Chunks of the same size are linked with the most recently freed at the front, and allocations are taken from the back. This results in LRU or FIFO allocation order, which tends to give each chunk an equal opportunity to be consolidated with adjacent freed chunks, resulting in larger free chunks and less fragmentation. * `top': The top-most available chunk (i.e., the one bordering the end of available memory) is treated specially. It is never included in any bin, is used only if no other chunk is available, and is released back to the system if it is very large (see M_TRIM_THRESHOLD). * `last_remainder': A bin holding only the remainder of the most recently split (non-top) chunk. This bin is checked before other non-fitting chunks, so as to provide better locality for runs of sequentially allocated chunks. * Implicitly, through the host system's memory mapping tables. If supported, requests greater than a threshold are usually serviced via calls to mmap, and then later released via munmap. */ /* sizes, alignments */ #define SIZE_SZ (sizeof(INTERNAL_SIZE_T)) #define MALLOC_ALIGNMENT (SIZE_SZ + SIZE_SZ) #define MALLOC_ALIGN_MASK (MALLOC_ALIGNMENT - 1) #define MINSIZE (sizeof(struct malloc_chunk)) /* conversion from malloc headers to user pointers, and back */ #define chunk2mem(p) ((Void_t*)((char*)(p) + 2*SIZE_SZ)) #define mem2chunk(mem) ((mchunkptr)((char*)(mem) - 2*SIZE_SZ)) /* pad request bytes into a usable size */ #define request2size(req) \ (((long)((req) + (SIZE_SZ + MALLOC_ALIGN_MASK)) < \ (long)(MINSIZE + MALLOC_ALIGN_MASK)) ?

This currently means to add 4 bytes overhead plus possibly more to obtain 8-byte alignment and/or to obtain a size of at least MINSIZE (currently 16 bytes), the smallest allocatable size. (All fits are considered `exact' if they are within MINSIZE bytes.) From there, the first successful of the following steps is taken: 1. The bin corresponding to the request size is scanned, and if a chunk of exactly the right size is found, it is taken. 2. The most recently remaindered chunk is used if it is big enough. This is a form of (roving) first fit, used only in the absence of exact fits. Runs of consecutive requests use the remainder of the chunk used for the previous such request whenever possible. This limited use of a first-fit style allocation strategy tends to give contiguous chunks coextensive lifetimes, which improves locality and can reduce fragmentation in the long run. 3. Other bins are scanned in increasing size order, using a chunk big enough to fulfill the request, and splitting off any remainder. This search is strictly by best-fit; i.e., the smallest (with ties going to approximately the least recently used) chunk that fits is selected. 4. If large enough, the chunk bordering the end of memory (`top') is split off. (This use of `top' is in accord with the best-fit search rule. In effect, `top' is treated as larger (and thus less well fitting) than any other available chunk since it can be extended to be as large as necessary (up to system limitations). 5. If the request size meets the mmap threshold and the system supports mmap, and there are few enough currently allocated mmapped regions, and a call to mmap succeeds, the request is allocated via direct memory mapping. 6. Otherwise, the top of memory is extended by obtaining more space from the system (normally using sbrk, but definable to anything else via the MORECORE macro). Memory is gathered from the system (in system page-sized units) in a way that allows chunks obtained across different sbrk calls to be consolidated, but does not require contiguous memory. Thus, it should be safe to intersperse mallocs with other sbrk calls. All allocations are made from the the `lowest' part of any found chunk. (The implementation invariant is that prev_inuse is always true of any allocated chunk; i.e., that each allocated chunk borders either a previously allocated and still in-use chunk, or the base of its memory arena.) */ #if __STD_C Void_t* mALLOc(size_t bytes) #else Void_t* mALLOc(bytes) size_t bytes; #endif { mchunkptr victim; /* inspected/selected chunk */ INTERNAL_SIZE_T victim_size; /* its size */ int idx; /* index for bin traversal */ mbinptr bin; /* associated bin */ mchunkptr remainder; /* remainder from a split */ long remainder_size; /* its size */ int remainder_index; /* its bin index */ unsigned long block; /* block traverser bit */ int startidx; /* first bin of a traversed block */ mchunkptr fwd; /* misc temp for linking */ mchunkptr bck; /* misc temp for linking */ mbinptr q; /* misc temp */ INTERNAL_SIZE_T nb; if ((long)bytes < 0) return 0; nb = request2size(bytes); /* padded request size; */ /* Check for exact match in a bin */ if (is_small_request(nb)) /* Faster version for small requests */ { idx = smallbin_index(nb); /* No traversal or size check necessary for small bins. */ q = bin_at(idx); victim = last(q); /* Also scan the next one, since it would have a remainder < MINSIZE */ if (victim == q) { q = next_bin(q); victim = last(q); } if (victim != q) { victim_size = chunksize(victim); unlink(victim, bck, fwd); set_inuse_bit_at_offset(victim, victim_size); check_malloced_chunk(victim, nb); return chunk2mem(victim); } idx += 2; /* Set for bin scan below.

Run this first on the logfile when you update your statistics. You can run this on the same log file day after day. The header for this program contains the following variables. database - set this to the path and filename where the muddleftpd statistics database will be stored. muddle_log - set this to the path of the log file to scan. - muddlestats.pl This is a front end to the statistics package. It generates a series of detailed html pages using the information from the statistics database. The files are placed in a given directory to be served via webserver. The following variables need to be set in the program header. database - set this to the same statistics file you used in muddlestats-gather.py wwwroot - set this to a directory where the webserver can serve the files. It should be an empty directory so it can output files like index.html into it. mainfile - set this to whatever the webserver uses as the default file in a directory. fileprefix - all files (except mainfile specfieid above) created by muddlestats.pl will have this prefix. uploads_first - I have no idea what this does, I recommend just leaving it as is for now. bgcolor - sets the background colour for all pages generated. textcolor - sets the text colour for all pages generated. linkcolor - sets the link colour for all generated pages. tablecolor1 tablecolor2 tableheader - not sure what colours these set, play with them. chartbgcolor - the background colour for all generated charts. One way that muddleftpd statistics can be gathered are via logrotate.d. Included is an example logrotate.d file that shows how to do it. It can also be done via crontab if you don't rotate your logs usin logrotate. ------------------------------------------------------------------------------ Basic Installation ================== Not much for now. See the scripts' headers and the enclosed directory structures. Oh. And one more thing... this program won't run without the 'python' interpreter v1.5+ muddleftpd-1.3.13.1/tools/muddlestats.0.3.0/README0100644000175000017500000000017507544536577020124 0ustar joergjoerg Re all!

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. muddleftpd-1.3.13.1/ChangeLog0100644000175000017500000002325507751444024014655 0ustar joergjoerg2003-11-03 Joerg Jaspert * modules/auth: authlibexample/Makefile.in, authlibmud/Makefile.in, authlibsmb/Makefile.in, authlibmysql/Makefile.in, authlibmsql/Makefile.in: Added -fPIC so it actually compiles on different platforms. 2003-11-02 Joerg Jaspert * configure.ac, modules/auth/authlibmysql/configure.ac: Changed way we look for mysql. Thats easier for users now. * modules/auth/: authlibmsql/auth.h, authlibmysql/auth.h, authlibsmb/auth.h, authlibmud/auth.h, authlibexample/auth.h: Changed include from varargs.h to stdarg.h as gcc no longer includes varargs.h * modules/auth/: authlibmsql/README, authlibmysql/README, authlibsmb/README, authlibmud/README, authlibexample/README: Changed documentation to be in sync with new configure/makefile things. * modules/auth: authlibmsql/Makefile.in, authlibmysql/Makefile.in, authlibexample/Makefile.in, authlibsmb/Makefile.in, authlibmud/Makefile.in: Change Install Target from TODO to something useful. Install the autlibfile in libdir/muddleftpd set by configure run. Also install the READMEs as README.auth$MODULE in the documentation dir (see below). * doc/Makefile.in: Added things to install txt documentation in prefix/share/doc/muddleftpd/* 2003-11-02 Beau Kuiper * src/ftpd.h: removed headers for string.h since they are in string.h. Updated prototype for safe_vsnprintf(). * src/string.c: fixed double use of varargs in string_catvprintf(). This fixed muddleftpd problems on PPC and possibly other archs. * src/string.h: updated prototype for string_catvprintf() * src/ftpout.c: modified ftp_write to use fixed string_catvprintf() * src/logger.c: modified debuglog() to use fixed safe_vsnprint() * src/utils.c: fixed possible double use of varargs in safe_vsnprintf() Fixed safe_snprintf() so it does not use safe_vsnprintf() to prevent performance degredation due to new design. * Configure.ac: Added a check for stdarg.h, since the replacement snprintf code needs it. 2003-04-15 Beau Kuiper * src/main.c: mainprog(): added code to close all file descriptors. After the server is started, it will also close the terminal file desciptors, so ssh sessions are not stalled at logout. * src/utils.c: fd_closeall_nonterminal(): determines the max file descriptors number and attempts to close all open fds. The terminal file descriptors are left untouched. 2002-11-20 Beau Kuiper * src/acl.c: transfer_config(): Added code that allows the server to retrieve the gid a user will operate as from the password file. Just put "!" in front of the gid parameter. (eg gid !anuser) will give the user the gid of the user anuser. 2002-10-29 Beau Kuiper * src/string.c: string_filterbadchars(): Added code to only allow /r and /n characters if and only if they are together as a TELNET newline (/r/n). This fixes the bug of muddleftpd accepting input with those characters in it and then mucking the log files up with it. * src/logger.c: Removed code that replaces /r and /n with spaces. It doesn't need it anymore, since I have cured the original bug. 2002-10-21 Joerg Jaspert * modules/auth/authlibexample/COPYING: Added back.

If you break something that was working before you checked in your code, it's your responsebility to get it working again. If you ask the other developers real nicely, maybe they'll help you, but it is your responsability. - Try to keep all your changes limited to the specific area you are working on. - Peoples interests change. Workloads change. So if you have code for a task you are working on that is an improvement on what is in CVS already, feel good about checking it in. If it doesnt break anything, and adds/fixes something, it's a good thing to add to the repository. If you're working on something complex, and you want something committed as an intermediate step, then it might be okay to commit what you have. But try not to commit anything that is completely broken. At minimum, check in something that is partially working, with clear comments about "this isnt working yet, but this is what I'm in the process of doing to get there". - Write good cvs commit messages. Not just "modified" or blank lines. It will be used for the ChangeLog, so it should really show what you have done. A URL with good hints for ChangeLog entries is http://www.red-bean.com/cvs2cl/changelogs.html If you follow that as close as possible for your commit message everything is fine. 1.2 CVS Branches The Muddleftpd CVS repository has one primary tree, called MAIN. They can be 0 to many branches used for quality control and developing new features. Note: All branch identifiers and tag names starting with release_ are reserved and only used to indicate different release versions. MAIN This tree is under full control of Beau Kuiper. If you want to change things here you have to get his OK first. That is to ensure the quality and security of muddleftpd because all code added here has to be fully reviewed. This tree will be branched to create new releases and everyone that commits here (after the OK) has to make sure HE DOESNT BREAK IT. release_* These branches are under control of Joerg Jaspert. He is the only one who makes new releases. * is replaced with some information, see 1.3 below. Such a branch is the place to fix bugs in a released version. See below for more about that. dev_NICK_feature Every developer is allowed to create a branch within the repository. Just replace NICK with the nick you have on Savannah and feature with the feature you want to develop in that branch. That way everyone knows whats going on with a particular branch. He is then fully responsible for that branch, so if you want to work on anothers developers branch talk to him first. Developers can use that to work on new features/enhancements without breaking the MAIN tree of muddleftpd and without the rules that are for that tree. Example: If you want to work on IPV6 support you create a branch called something like 'ipv6' and do your work in it. Every then and now you look at MAIN if there are interesting changes and merge them into your branch if you like them. After a while you are finished and at the point where you can say "Yes, its stable and good enough for MAIN". Then you "freeze" this tree, eg. stop working on it and telling all other that its frozen and coordinate with Beau to get it merged into MAIN. Then you only commit things into that branch that are needed to get it accepted into MAIN, and after all things are sorted out you and Beau merge it into MAIN. Voila, a new feature is there without breaking of our MAIN line. :) If you ever create a branch and find out later that you dont need it, you can remove that branch from the repository. The project admins are allowed to do that for dead branches that arent used for longer then 2 months to keep the repository clean. But please never remove a branch that has development work in it, even if it is not used at the moment or looks like it never will again. It may contain important source changes/ ways to solve a problem we can use at a later time. 1.3 Muddleftpd Releases A new version of Muddleftpd is released after it is finished. There is no general timeframe like "every 2 month". Release states: Development Development of Muddleftpd is ongoing. The work is done in MAIN (see above) and in developer-created branches. You can add as many new features as you want (see notes for MAIN above). Frozen From time to time Joerg will create a new Branch in the CVS repository called release_X_Y_Z. X_Y_Z is replaced with the version number of the upcoming release with the following schema: X - "Big" Major. If changed then new features in Muddleftpd may break existing setups. Y - Major. Changed for new features. Doesnt break old setups. Z - Minor. Indicates bugfix releases and enhancments to existing features. No addition of new things. Sometimes there maybe a fourth part of the version number. That is done for security or important releases of an existing release. See 1.4 NO new features or enhancements are added to such a branch! Released. After creation of the release_X_Y_Z branch the code in there is heavily tested and reviewed by the developers, commiting their changes to that branch, so we get it as bugfree as possible. Again: NO new features/enhancments are added, only bugs fixed. If we get to the conclusion that we have done every possible thing to ensure this, a new Release gets out and the work on this branch is stopped. Get back to MAIN and your own branches now and add new cool things guys :) 1.4 Security Updates, Important Bugfixes It may happen that a released version of Muddleftpd has a important or a security bug. Thats bad, but we are all humans, it can happen. For our last official release we will follow the following procedure: We will fix that error in the release_* branch of the last release. We will NOT add any features or anything else to that tree, just fix that bug and get a new stable release out. That will be numbered the same as our last release with an added .X to the version number that indicates that its changed. eg. a Bugfix to 1.2.9 will be 1.2.9.1, a (maybe) second bugfix then 1.2.9.2 and so on. That way we dont have to push out a new release if we dont think it is finished yet (hey, we aim to produce a secure ftp daemon, that needs time) but still can react quickly on such bugs. 1.5 ChangeLog Entries and CVS commit messages (log messages) First please take a look at the following URL. The text there is really good, you should follow it as close as possible: http://www.red-bean.com/cvs2cl/changelogs.html We require that you follow these guidelines while creating your ChangeLog entry. Reasons are listed there too, mainly to have a clear log of changes that are done to the source. Talking about messages for cvs commit: You can just re-use the logmessage from the ChangeLog for the commit message (Emacs CVS Mode does it for you if you use that), thats fine. But if you write them by Hand it is enough if you write a clear sentence (or many of them) describing your changes to the file(s) you commit. For details everyone could look into the ChangeLog. But NEVER commit with an empty Message or just a "changed". That way everyone can follow the changes you made with the cvs log output and can look into the ChangeLog file for a detailed description of the changes. 1.6 Code Submission if you are not a developer of Muddleftpd When you fix a bug or add a feature, you must submit a unified patch (see below for instructions for creating the patch) to the Patch Manager on Savannah, and also announce it on the mailing list (do not send the patch to the list, just send a short announcement). You must NOT submit the entire changed file, nor just the changed lines of code. If you submit something other than a patch created using the instructions below, you will be asked politely to resubmit your changes as a patch. Your code will not be merged until you do. Note: If your patch is around twice the size of the file you're patching, something went wrong. DO NOT submit that patch. If you edited the file on a non-unix system, and transferred it to a unix system to run diff on it, you need to make sure the end-of-line characters are the unix kind. Ask on the mailing list if you have this problem. Example: To create a unified patch suitable for submission, have both your modified source tree and the original source tree avaliable. Prepare both trees for comparison by running the following (on both trees): bash$ ./configure bash$ make maintainer-clean Now compare the two trees using the following command: bash$ diff -r -u3 [path to original tree] [path to modified tree] > patchfile Patchfile will now contain your patch and you can submit it. Be sure that you don't mix the original and modified tree paths up, otherwise your patch will end up backwards. Note: if you need to use your tree again after creating the patch, simply run ./autogen.sh in the source tree. This will automaticly regenerate all the configure scripts. 1.7 How to become a developer Well, thats not that hard. Of course we require a little knowledge, so you have to prove you can do the work you say you want to do. If you want to work on muddleftpd's source you need to do that before you get access. Just write some enhancement/new feature to muddleftpd (look at the task list for ideas what can be done). You do that with the latest copy of the CVS Source. Then use diff -u or cvs diff -u to create a patch and submit that at the Savannah project. If you want to work on the documentation or website part it is mainly the same: Show us that you are able to do this and you can get your access. muddleftpd-1.3.13.1/INSTALL0100644000175000017500000000012107544536576014135 0ustar joergjoergINSTALLING MUDDLEFTPD: See doc/muddleftpd.txt CONFIGURING: See doc/config.txt muddleftpd-1.3.13.1/Makefile.defs0100644000175000017500000000177407544536576015503 0ustar joergjoerg# Copyright (C) 1999 Beau Kuiper # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This lead to ftpwho printing the hostname after the operation. 22) Bug Fix: cookies in access directives were not being applied correctly. 23) Bug Fix: Signals must be blocked while reloading config, or deleting users, or bad things happen Version 1.3.4: 1) Bug Fix: The internal password module was feeding the config error function the wrong variable. 2) Bug Fix: Fixed a bug in include handling that would prevent use in 64bit environments. 3) Bug Fix: Include looping is now checked before config file is loaded. 4) Change: Removed authparams option. Auth modules get to fend for themselves (this provides more functionality, and better directive names) 5) Bug Fix: Help was not being shown correctly. 6) Documentation: Updated some documentation. 7) Bug Fix: Possible to free NULL pointers in config.c 8) Change: Changed a few error messages to be more understandable. 9) Change: A temporary change that will lock up muddleftpd if it tries to free a NULL pointer. It locks muddleftpd up so a debugger can get a clean backtrace of the program. 10) Bug Fix: Fix for attempting to rotate logs while in droproot mode. 11) Bug Fix: Usernames are more rigourously checked because regular expression characters in accepted usernames may provide more access than intended. 12) Change: The anonymous authentication module now returns the uid and gid of nobody instead of the ftp user. This is more consistent with other ftp servers. 13) Change: Listing of devices is more accurate, showing the major and minor device numbers like real ls. 14) Change: Muddleftpd now uses the real hostname as the default hostname of the host and virtual servers. 15) Change: Ipacl for hostnames must be in brackets. Without brackets, it is always checked against the IP 16) Bug Fix: got rid of any use of inet_ntoa, since I wasn't using it right. 17) Change: Set default logstrength to log everything. 18) Documentation: Documented all server directives. Version 1.3.3: 1) Change: Can now use %v in group config to get current virtual server section name and %V to get current virtual server host name. Ratio %v and %V are now %a and %A 2) Change: Can now use tokens in greeting line. 3) Bug Fix: Fix for bug where directories with % in them did weird things (see version 1.2.10) 4) Change: New config option droproot. This option will drop all root prividges when a user logs. It also will use capibilities so it can still use low numbered ports on linux 2.2 or better if libcap is installed. 5) Change: reply.h now contains macros to the replys the server generates, It allows replies for foriegn languages or other ftp servers to be used, basicly changing the persona of the ftp server. 6) Bug Fix: muddleftpd was not correctly enforcing the one command at a time requirement of FTP. 7) Bug Fix: muddleftpd was not updateing upload/download byte counter. Version 1.3.2: 1) Bug Fix: Muddleftpd is much more careful now about the configuration file it listens to. The config file now must be owned by the user/group who runs it, and must not be world or group writable. This fixes a security vulnerability in ftpwho if it is setuid. Same for internal password files. 2) Change: Added the -n option to display IP's instead of hostnames in ftpwho. 3) Bug Fix: Fix for truncated replys where length of reply was more than 1024 characters. 4) Change: Implemented new directive include, which allows you to include another section in the current section. Good for creating templates. 5) Change: Changed how config errors were handled, improving error reporting and detection 6) Change: By default, muddleftpd is built to be quiet on startup. 7) Change: ratios now get data from groups section rather than a separate section. Use include to have ratio directives in other sections. 8) Change: Sending SIGUSR1 to the server process will make it reopen the log file and instruct the children servers to do the same. Note that chrooted server children will not be able to reopen the log file. 9) Change: added fnmatch pattern based access controls, including controls to explicitly match slashes. 10) Bug Fix: Maximum process limit setting was broken, fixed. 11) Bug Fix: Symbolic links were always assumed readable in the listing code. Does not work because the /proc filesystem actually has non-world readable symbolic links. Version 1.3.1: 1) Change: Minor changes to how the scratchfile is used. 2) Change: Muddleftpd now uses proper unix style arguments. It has a usage screen and a version option. 3) Change: PORT command more verbose, repling where it will connect to. 4) Change: root privliges are given for connecting to low number ports. This is for RFC951 complience. 5) Bug Fix: Fixed code so muddleftpd runs of FreeBSD. Borrowed :-) some code from proftpd (for functions fgetpwent and fgetgrent) 6) Bug Fix: snprintf replacement code has a bug causing very bad problems. 7) Bug Fix: removed TCP_CORK code since it only slows data transfers down. 8) Bug Fix: Fixed a few compile bugs. 9) Change: Changed log format and how log was written 10) Change: Added support of dlopen modules for authentication modules 11) Change: Minor updates to authentication module interfaces. 12) Change: Passwords used by anonymous users are now logged. 13) Bug Fix: Fixed %N cookie for user count. 14) Change: Got rid of pidfile support, now ftpwho -p will return the pid of the running standalone muddleftpd. 15) Change: Now scratchfile is used for locking in both inetd and standalone modes. This means the server doesn't need to lock against the config file and it could be changed without problems. 16) Change: ftpwho program rewritten and much more useful now :-) 17) Bug Fix: A couple of missing returns fixed. Should have caused problems already :-) 18) Bug Fix: A bug in acl.c fixed where segfault would occur if no ACLs were specified for a user 19) Change: Authentication modules can now cancel authentication of a user if a serious error occurs. 20) Change: Authentication is now cancelled if an authentication module cannot be found. 21) Change: If muddleftpd cannot bind to a port when it starts up, then it will exit. If it cannot bind to a port when you issue a SIGHUP, then it will log it and continue. 22) Change: Commands can now be disabled per group within the config file. 23) Bug Fix: Data corruption bug after SIGHUP removes a virtual server fixed. 24) Change: When a user connects, muddleftpd will fail to recognize all but a few commands needed to login. 25) Change: ftpwho reports vservers using their section names. 26) Change: Now download speed limits can be specified per group These are highly accurate and reasonably smooth. 27) Bug Fix: Porting fixes for weirder unixes including simple-glob fixes. 28) Bug Fix: Small bug parsing gid lists caused crashes with long suplemental gid lists. 29) Change: Speed limits now also apply to file lists and uploads. 30) Bug Fix: New listing code would possibly break when a partial write occured. 31) Change: Finished logindumpdata support. Version 1.3.0: 1) Bug Fix: for large maxusers, the default settings would cause muddleftpd to croak. Fixed. 2) Bug Fix: for long usernames and non-default constant values, a possible problem with setting username has been fixed 3) Change: PAM module now does more logging to aid debugging. 4) Change: shared memory is more compact now, only storing thread users. 5) Change: EXPERIMENTAL INETD SUPPORT!!!! 6) Bug Fix: on systems that need -ldl for pam support, it would cause pam support not to compile. Fixed. 7) Bug Fix: if muddleftpd is running inetd mode, now errormessages go to the system log. 8) Change: Log message now emmitted if non-existant auth method used. 9) Change: Better debug logging system now in place. Can work even with inetd 10) Bug Fix: Fix to MDTM. This broke netscape quite convincingly 11) Bug Fix: Fix for netscape race and maybe other clients. 12) Change: All configuration is in single file now! This improves performace muchly esp under load. 13) Documentation: Examples updated for new code! 14) Bug Fix: Fix to logging where SITE commands were logged twice. 15) Bug Fix: Listing bug fixed where files were being used as regular expressions. 16) Chnage: Replaced ACL code. New code also recognises mkdir and rmdir, chmod and chdir. Add only applies to files now. 17) Change: Now ip's can be denied as well as allowed with the new ipacl directive. Note that the order ipacl's are specified in is very important. 18) Change: Now log messages are generated when a user logs out of the server. 19) Bug Fix: User cannot specify PORT command with data port < 1024 20) Bug Fix: Total file size is now given when doing binary downloads, regardless of starting position. Other ftp servers act this way, and some client expect it. 21) Bug Fix: Maximum timeout was not correctly set. 22) Change: Writing to control port now has timeout, so it cannot lock up. 23) Change: Continuation messages have new format that look nicer. 24) Change: New group system is working, It now traverses a list of groups in the user file to determine what group a user is. It needs more work ATM. 25) Change: added IP and name access lists to make group system very, very, very configurable. 26) Bug Fix: For systems which uses non-DES encryption, muddleftpd used crypt correctly. 27) Change: added hostname based matching and hostnames in logs. 28) Change: reverse dns timout setting added 29) Change: Alternate long reply format option added, allows for bad proxys and stuff. 30) Change: VIRTUAL SERVER SUPPORT ADDED. Not yet completed or optimised for file descriptor usage. 31) Bug Fix: Fixed several small bugs found in 1.2.2. 32) Bug Fix: A minor bug working with parameters fixed. 33) Bug Fix: A bug when parsing config files caused tabs to be misinterpreted. 34) Change: Smart binding. This allow muddleftpd to minimize the number of file descriptors used when binding files. 35) Change: Zero binding. When used with smart binding above, allows virtual servers to be used on all servers. This basicly makes sure all binds are performed on address 0.0.0.0 36) Change: Using rlimits instead of manually checking memory size for determining overuse of memory. 37) Change: Made single configuration file loading to be less memory intensive. 38) Change: Server will now reload config file with a HUP signal. 39) Change: Server now lets you specify if you want to real chroot to the rootdir instead of doing a pretend chroot. It is ignored if root access isn't avaliable. This provides extreme security for paranoid system administrators (like me!) 40) Change: When a user logs in, the uid/gid is switched to that user instead of being left as root. This reduces code size and improves security. I also seem to learn things the hard way (I should have had this ages ago) 41) Change: Ratio support. An external binary file is used for this, and users are added to it as they log in. Ratio's are implimented so multiple sessions are no problem. Ratios apply to both files and bytes, and can be persistant or non-persistant. 42) Change: Config changes. Now parameters are easier to specify, and including spaces is easy. 43) Change: By default, muddleftpd now doesn't allow access to non regular files (eg device files). To re-enable use devaccess in group sections. 44) Change: Full group support, include supplementry group lists. 45) Change: Added a ratio changing program, ratiotool. It can add, edit and psudo-delete ratio file entries. It is safe to use while the server is running. 46) Bug fix: Fixed a small bug that always put an extra / at the beginning of a filename in the log if rootdir is / 47) Change: If rootdir contains symlinks, they are now dereferenced as the user logs in. 48) Change: Added a realdir option. This will automaticly report the real directory name, with all symlinks dereferenced, instead of the internal construction. 49) Change: Added code to detect broken snprintf, and to work out which syntax it uses and use that syntax. 50) Change: Detects if double ints work correctly and disables ratios if they don't 51) Change: Added fxpallow option, so server-server transfers may work on a per-group basis. 52) Change: Implemented output buffer to make sure long replies are sent effeciently. 53) Change: Input from dumped files and user is now put through a filter that removes non-printable characters. 54) Change: Implemented options to specify long replies directly in the config file 55) Change: Data port handling rewritten, should be a little faster now. 56) Change: Sendfile() support implemented. This should improve performace slightly, but linux needs a better sendfile :( 57) Change: Groups and vserver limits are handled in a much better way now. Faster for standalone operation, correct for inetd operation. 58) Change: Log now contains thread id so it is easier to trace what a specific user is doing Version 1.2.10: 1) Bug Fix: Bug where % in pathname would cause weird errors when current directory was displayed. It was caused by using the output of one printf (with user supplied data) as the format string in the next. Fixed by removing all (except where it is obviously safe) non-constant format strings in the source. Entire source was checked for the problem. Version 1.2.9: 1) Bug Fix: Mudpasswd backported from 1.3.X. Fixes problems with mudpasswd segfaulting. 2) Change: Included an init file for system V init scripts 3) Chnage: Added a spec file for rpm generation. Havn't tested it yet. Version 1.2.8: 1) Bug Fix: Another config file reading bug fixed. If you used tabs at the end of a value, they would not be discarded by the ftp server. 2) Bug Fix: Repaired the README file. Version 1.2.7: 1) Bug Fix: Rename bug fixed. Ops :-) Occured because errno wasn't reset correctly. Version 1.2.6: 1) Bug Fix: Fixed bug where garbage was printed if null password was supplied. Version 1.2.5: 1) Bug Fix: snprintf madness fixed. Server now works for all known snprintf types. 2) Bug Fix: fixed the provided snprintf so it reports -1 if result is too long. 3) Bug Fix: ftpwho would segfault in certain denied access cases. Version 1.2.4: 1) Bug Fix: Parsing problems with tab separating name and value pairs fixed. 2) Change: Ftpwho program revamped. It can now do reverse IP lookups for hostnames and supports regular options. Run ftpwho -h to see options. 3) Bug Fix: Problems with zero length strings on ftp commands fixed. No real problems, just zero length parameters need to be detected and reported as missing parameters. 2) Bug Fix: A secuity problem with cddump relative files has been fixed. If the user could create a symlink as the name of a relative cddump file, the user could view any file on the system over the control connection. Version 1.2.3 (was 1.1.1c) 1) Bug Fix: Active data connections now bind to specific interface. Old method seemed to fail when used with strict ip filewalls. 2) Bug Fix: If an error occured accepting a control connection, the server would bad. 3) Bug Fix: If the PASV command couldn't bind to a port, it wouldn't cleanly report the error. 4) Bug Fix: An extra close was hiding the real cause of data port connection failure. 5) Bug Fix: Some calls to create sockets were not checked correctly. 6) Bug Fix: No error was displayed if passive port connection accept fails 7) Bug Fix: Slight change in Makefile so that CFLAGS is recognised. Version 1.1.1b (now 1.2.2): 1) Bug Fix: if you didn't set authmethod in the config file, the server process would crash. 2) Bug Fix: if you use a non-DES crypt function, muddleftpd would not authenticate properly. This bugfix fixes for a least slackware 7.0. 3) Change: New versioning system. Now I copy the linux versioning system since I cannot get it right myself. 4) Bug Fix: if a list failed due that was not the fault of glob, then server would crash tring to free a non-existant variable: 5) Change: You can use group/usernames for uid/gid specification now in user config files and authentication modules. Version 1.1.1a (now 1.2.1): 1) Bug Fix: Long usernames would cause the server to crash. Not an exploitable bug, but not very nice looking. 2) Bug Fix: files dumped over control connection were not logged correctly. Version 1.1.1 (now 1.2.0): 1) Bug Fix: A minor memory leak was sealed. 2) Bug Fix: Changed ACL error code to EACCES instead of EPERM. 3) Documentation: Added the info file back. 4) Change: log entry generated when a user logs out of the ftp server 5) Bug Fix: Server will not allow client to specify a data port less than 1024. 6) Bug Fix: Changed byte count when starting download to total size of file regardless of restart position. Other ftp servers act this way, and some clients use this info. 7) Change: When authenticating users, the server will change to the configuration directory. This will improve robustness of marginally defined configurations. 8) Bug Fix: Maximum timeout was not set correctly when logging user in. 9) Bug Fix: Minor fixes for platform independance in mudpasswd. Version 1.1.1beta3: 1) Bug Fix: invalid rootdir message didn't show root dir. 2) Bug Fix: fix for site commands being logged twice. 3) Documentation: info files removed for now since maintainer hasn't reponded to email. 4) Bug Fix: Directory listing problems solved. Version 1.1.1beta2: 1) Bug Fix: Pam support didn't compile on system with dynamic linking in a library 2) Bug Fix: Small change to code to prevent problems if username length constants get changed. 3) Bug Fix: Fix to MDTM command, broke netscape access quite well :) 4) Bug Fix: Fix for netscape race and maybe other clients. Version 1.1.1beta1: 1) Change: Changed the error message management system. Now much better. 2) Change: Help now contains descriptions for each command. 3) Change: Full shadow password support with account expiry. 4) Change: User now gets message as to why login fails. 5) Bug Fix: strerror was compiled even if it already existed! 6) Change: PAM support has been added! 7) Bug Fix: now all root logins get demoted to user nobody like they should 8) Bug Fix: now user nobody from the password file is used to determine what user nobody is. Any system without a user nobody is in SERIOUS TROUBLE! 9) Change: Added the disabled user authentication which will disable a user. 10) Bug Fix: Added a copy of the usleep function for older computers. 11) Documentation: Fixed documentation for new features. 12) Bug Fix: Put limits on maximum generated string lengths to prevent users from filling virtual memory. 13) Change: Added SITE IDLE command. Version 1.1.1beta0: 1) Change: Log message emitted when user cannot login due to bad root dir 2) Change: Error messages for socket connection are better handled. 3) Change: added -d option to list a directory instead of its contents. 4) Change: Major refit of auth code. Now all auth code is modularied into the different sources. Makes adding new auth schemes easily. 5) Change: new unix auth module can autodetect shadow passwords! 6) Change: config files can handle windows style files. 7) Change: added an internal password file support module. 8) Change: added runasuser option in main config file. 9) Change: removed runasuid and runasgid from main config file. 10) Change: created a simple mudpasswd program to modify internal password files. 11) Change: Minor server reply tweeks. 12) Documentation: Fixed examples for new code. 13) Change: Added the badauthwait option to the main config file to cause the server to wait a specifed number of milliseconds if the user doesn't provide the correct password. 14) Change: Added the userjail option to user files so when the user logs in, he/she will not be able to log into a new user. Good for anonymous accounts. 15) Change: Added the logintrys option to the main config file. This tells the server how many attempts a connection has to login before the server refuses to log the user in. Version 1.1: 1) Documentation: Added man page and info pages. Thanks to Jonas Oberg for this. 2) Bug Fix: Spelling mistake in init.c fixed. Thanks to Jonas Oberg for noticing my mistake. 3) Change: Server will now detect if it needs root access to bind to a port and gives a message to the user if it is so. Version 1.1.beta3: Final beta if no bugs are found! 1) Bug Fix: Fixed Makefile so QUIET=1 option is recognised. 2) Bug Fix: Fixed spelling mistake in init.c (already instead of aleady) 3) Documentation: Added some documentation on how to build and install muddleftpd (muddleftpd.txt) 4) Documentation: Updated README and INSTALL. 5) Bug Fix: If unixuser is specified and that specified user doesn't exist, login will fail automaticly. 6) Bug Fix: If it can't load a user's config file, it will now output a log message. 7) Bug Fix: Checks on files and directories now done in user auth files. 8) Change: Minor optimisations to improve processing of file dumping, streamlines code. 9) Bug Fix: busydump was crashing, due to incorrect working directory value, fixed! 10) Bug Fix: the username in the shared memory structure is properly updated at the correct time. Allows a user with maxconnect 1, to relogin. 11) Documentation: Added documentation for user configuration files. 12) Bug Fix: now mud authenication stuff is not compiled by default. 13) Documentation: Added documentation for cookies in user config files. 14) Documentation: Added documentation for accepted ftp commands. 15) Documentation: Gave up on HTML documentation! Version 1.1.beta2: 1) Change: Failed magic cookie tranformations are logged so that the admin can find if cookies fail. (I decided that this change is minor enough and important enough to be added before version 1.1) 2) Bug Fix: Download statistics were not correctly tallyed. 3) Documentation: Added documentation for dumped file magic cookies (cookies.txt) 4) Documentation: Added documentation for ftpwho. (ftpwho.txt) 5) Documentation: changed user.other so that if the example config is directly used, it won't open gaping holes in the system. 6) Bug Fix: Server dies improperly on startup if shared memory isn't initalized 7) Bug Fix: Commented out error message about shadow passwords not working as root. Change 1 should produce a log entry if the user tries to use shadow passwords without root access. 8) Documentation: Created a new set of examples, that are more secure, and better for creating a full configuration. 9) Bug Fix: Updated socket.c, now if the server fails binding data connections for any reason, it lets the computer choose the port. Version 1.1.beta1: Thanks to Mike Javorski for the first 3 fixes. 1) Bug Fix: Removed SO_SNDLOWAT and SO_RCVLOWAT log messages because they are unimportant and seem to be annoying people :) The feature is still there, it will just fail quietly on systems that have problems with it. 2) Bug Fix: Manual page installation fixed (but commented out becuase the manual page is yet to be written. 3) Bug Fix: Fixed ftpwho.c for ANSI C complience. Now main returns an int. 4) Bug Fix: Defined prototypes for listing functions and found a bug where they wern't supplied correct parameters. 5) Bug Fix: Server now checks if you are already logged in before accepting a password command. 6) Bug Fix: Ops, I must have been on drugs to not have noticed this bug before now (and write the broken code). SIZE in ascii mode was badly broken. 7) Bug Fix: SITE CHMOD was broken and logged out the client 8) Bug Fix: HELP missed the first command when printing out a command list. 9) Bug Fix: When using runasuid/runasgid, the parent terminal holder would not get killed due to the process not having permission after changing uid. 10) Bug Fix: When using runasuid/runasgid, and listening on ports less than 1024, muddleftpd would fail to create data ports because it couldn't bind to the port. 11) Bug Fix: prototypes in ftpd.h for procnum.c fixed. 12) Bug Fix: ftpwho.c now includes as required. 13) Bug Fix: fixed compiler warning compiling sglob.c on systems without glob. 14) Bug Fix: Prototype for strerror if the system hasn't got an strerror 15) Bug Fix: Fixed problems about double defining crypt 16) Bug Fix: -lsocket and -lnsl should work for machines that need them now. Version 1.1.beta0: 1) Bug Fix: forkwrapper is declared int instead of pid_t in ftpd.h fixed. 2) Bug Fix: On systems that don't support GLOB_PERIOD, compile will fail, fixed. 3) Documentation: Added some documentation for the main config file, in doc/config.txt 4) Bug Fix: Compile warning fixed for ftp.c 5) Bug Fix: Fixed race condition in starting up program where tty could hang if the parent recieved the signal to give it back too soon. 6) Documentation: Added some HTML documentation (just a quick conversion of doc/config.txt) Version 1.1.alpha5: Imposing a feature freeze for Version 1.1. Only bugfixes and documentation from here. 1) Change: Magic cookies when authing clients is now handled more gracefully. No user side changes. This allows Change 6. 2) Bug Fix: Empty listing caused memory leak. Fixed. 3) Change: Server now holds the terminal until after the startup messages so the prompt occurs after it. 4) Change: Startup message fixed for correctness. 5) Bug Fix: pids are now type pid_t, gids are now type gid_t, and uids are now type uid_t in my program. They were ints before!. 6) Change: Now magic cookies work in dumped files (eg welcome file) so you can give info out. The cookies are similar to the real wu.ftpd cookies. 7) Change: Added email option in config file for magic cookie %E. 8) Change: Now you can bind to a port to a specific interface by using port/ip as a parameter to ftpport. eg to bind port 21 on the loopback device use "ftpport 21/127.0.0.1" in the config file. Version 1.1.alpha4: 1) Change: SITE command now operates similarly to normal command. No user visible changes. 2) Change: Messages have changed so that the code is more general. 3) Change: STAT ACCESS has been moved over the SITE ACCESS. 4) Change: help routine is more generalized, giving better results, less code and more maintainablity. 5) Change: Now I use config.h instead of lots of compile options. Thanks to Decklin Foster for the patch. 6) Change: The pidfile is used to check if muddleftpd is still running. If it is, muddleftpd refuses to start. Note, you can still have multiple instances of muddleftpd if they run with different config files. 7) Bug Fix: config file name was not initalized properly. 8) Change: Added a new user config option (quitdump) that prints a file when the user quits. Version 1.1.alpha3: 1) Bug Fix: New parameter bug where process will segfault if it cannot correctly substitue a %(a,b)h parameter. 2) Change: Ftp listing is better now, it recognises the -a option and displays all files. This improves interpolability with misbehaving clients. 3) Change: I removed the status reporting option and the code that does it. 4) Change: Shared memory used by muddleftpd can now be externally accessed. (for things like ftpwho) 5) Change: Added a simple ftpwho program that actually works without races by accessing the shared memory. 6) Change: The default config file is now specified in config.h Version 1.1.alpha2: 1) Change: Changed the status reporting so it now dumps info into a file that can be read by other programs. 3) Change: The admin now has the option to create a pidfile as muddleftpd starts. 2) Change: Changed the way parameters are processed. Now you can select a range of characters to include. eg %(10,12)h means to substitute characters 10 through 12 into the string. The old %h still works. Version 1.1.alpha1: 1) Change: Added simple shadow password support 2) Change: Changed the way listing works. Simpler, easier 3) Change: now STAT works. 4) Change: A list cannot be longer than MAXLISTSIZE 5) Bug Fix: A long running LIST -n ./ bug has been fixed. It caused an embarrasing infinite loop. Been in there for ages. A big thanks to Richard(Sputa@os3.os.ds.mfcr.cz) for the tipoff. 6) Bug Fix: Resume position should not be allowed to be negative. Version 1.1.alpha0: * means ported back to 1.0 1)*Bug Fix: Rename fixed again to check if RNFR was run before RNTO 2) Change: The main routine now uses the select.c services. 3) Change: The server can bind to many ports, and serve ftp over them 4)*Bug Fix: Memory leak in displaying symbolic links in listing. 5) Change: Internal list function now displays setuid/setgid and sticky bit. Rewrote to be much smaller. 6)*Bug Fix: Fixed ENOTDIR error to becone MYERR_NODIR instead of MYERR_NOFILE in file.c 7)*Bug Fix: Minor changes to error descriptions in ftp.c 8) Change: ~ works for going to your home directory. 9) Change: Download/Upload now don't memmove buffer. 10) Change: make a substitute glob using old BSD re_comp calls for very old systems. 11)*Bug Fix: Uid/Gid cache full causes problems. 12) Change: for passive downloads, makes sure the host that connects to the dataport is also the host that the control port is connected to 13)*Bug Fix: Obscure bug in ftplist.c fixed! 14) Change: The server sets the high and low water marks for the sockets on opening a data connection to improve performace. 15) Change: Added the STOU command! 16) Change: Added the ability to type a file before the user logs in 17) Change: Added the ability to type a file when the user enters a directory. 18) Change: The welcome file is now an absolute filename instead of relative to rootdir 19)*Bug Fix: Timeout didn't get updated properly when user logged on. 20) Change: Added timeout to STAT command. 21) Change: Added the APPE command! 22) Change: Added the ALLO command. Does nothing. 23) Change: Added the ACCT command. Does nothing. 24)*Bug Fix: The server didn't kill children ftpd processes. Now it does. 25)*Bug Fix: If you didn't specify a groupname in a user file, the server would crash. 26) Change: Changed maxthreads directive to maxusers. 27) Change: Cleaned up reading of commands. 28) Change: Started to use assertions to debug code. 29) Bug Fix: Server full log message not logged correctly. 30) Change: select.c adjusted to work better. 31) Bug Fix: server made 2 replys on logout. 32) Bug FIx: server can handle lots of dataconnections now. 33) Change: now too many login message is configurable per user using the busydump directive. 34) Change: ASCII upload resume disabled. It is not actually possible to this safely. Use the APPE command instead. 35) Change: Changed data collection to use shared memory rather than pipes. Faster, easier to access and allows future changes. 36) Change: Error messages now output the filename and line the error occured on. 37) Change: I am starting to use assersions to test features, find bugs. 38) Bug Fix: Server exits if it can't write to the log file, i.e disk full or other fatal error. 39) Change: Passive is handled better througth the main select handler. 40) Change: A simple strerror replacement has been thrown in for unlucky systems that don't have it. 41) Bug Fix: High and low water marks are only set if the constants for them exist. See 14. 42) Bug Fix: --prefix parameter in configure works as expected. Version 1.0: These fixed are ported back from version 1.1.alpha0. 1) Bug Fix: very obscure and rare bug fixed in ftplist.c 2) Bug Fix: Memory leak fixed in listing symbolic links. 3) Bug Fix: Rename fixed to check if the command RNFR was run first. 4) Bug Fix: Fixed ENOTDIR to become MYERR_NODIR instead of MYERR_NOFILE in file.c 5) Bug Fix: Modified error descriptions in error.c 6) Bug Fix: Fixed problems with full UID/GID caches. 7) Bug FIx: Timeout wasn't updated when user logged in. 8) Bug Fix: children processes are now automaticly killed when you kill the parent. 9) Change: Changed maxthreads to maxusers in the config file 10) Bug Fix: If you don't specify a groupname in the user config file, then the server will crash. Version 1.0.beta3: 1) Bug Fix: Buffers in acl.c fixed. Checked the rest of the code for possible buffer problems. 2) Bug Fix: stats.c buffers fixed. (not really a problem) 3) Bug Fix: pnums.c buffers fixed. (not really a problem) 4) Bug Fix: ftplist.c buffers fixed. (not really a problem) 5) Bug Fix: Rename properly fixed. For some reason it worked with the bug, and that worries me a little! 6) Change: reentrant.c (old name for original threaded version) cleaned up a little. Version 1.0.beta2: 1) Bug Fix: QUIT stopped working on 1.0.beta1, now fixed. 2) Bug Fix: Buffers in auth.c fixed completely. 3) Bug Fix: newfile.c has a realloc bug in it. ie it used a pointer to the buffer after remalloc was run, and since realloc may move the data to a new location, it was unstable but difficult to debug! 4) Bug Fix: a couple of memory over-freeing bugs fixed. 5) Change: Symbolic links listed properly. Version 1.0.beta1: 1) Bug Fix: unimplemented type would print response code twice. 2) Bug Fix: %U wasn't recognized unless unixuser was specified. 3) Bug Fix: Permanent group changes specified in config file would not work. 4) Change: FTP server now runs data transfers (almost) completely non-blocking. Timeout and ABOR work properly. ASCII resume works now too. 5) Change: Most of the code has been rewritten to use dynamic buffers, removing most problems with fixed buffer code. 6) Change: cdup, pwd, and cwd all use the same code now, thus all return the current directory 7) Change: mkdir now uses the 257 return code. 8) Change: all commands now give better error messages based on the real error, not the most likely error. Version 1.0.beta0: 1) First Version with CHANGES file. muddleftpd-1.3.13.1/README0100644000175000017500000000527107544536576013777 0ustar joergjoergMuddle.ftpd INTRODUCTION New Features since 1.2 * Faster, Leaner, Meaner (maybe not leaner) * Inetd support (can combine with xinetd for even better protection) * Single configuration file, with sophisticated group selection (much faster) * Better ACL support * Clients are now get the hostnames resolved. * Virutal server support (both multiple ip and single ip) * Rlimits are set for memory overuse. * Reload config with HUP signal (automatic for inetd) * Real chroot for muddleftpd with root access * Supplementary group support. * persistant and temporary ratio support. * Sendfile support for linux, freebsd. * Group count limits. * Dynamicly linked authentication modules. * Per group command disable ability * Download/Upload speed limiters. * USR1 signal now reopens log file. * Signifcantly better listing support, recursive listings, closer to real /bin/ls * EPSV and EPRT ftp commands now supported (ipv4 only) New Features since version 1.0 (a lot): * more opertunities to print out files to the user. * more supported platforms. * listening to multiple ports for connections. Also you can bind to specific interfaces now (on operating systems that support this). * better listing. * complete command set. * shadow password support. * magic cookie improvements (hmmm, cookie). Magic cookies can now be used in files that get printed to the user. * ftpwho program now added and operational. * STAT commands have all been moved to the more general SITE command. * user statistics (only minimal) * lots of non-visible changes, * and of course, bug fixes. DESCRIPTION: FTP servers tend to always want root access to do even the most basic stuff. This ftp server was designed to overcome this limit without limiting the access protection and safety of a regular ftp server. This ftp server can operate as a replacement for wu-ftpd, or it can operate under a single uid, running without any knowledge of the system password file. Anonymous access is availible too and you can actualy create as many guest accounts you like with same or different properties. To do this, it has full access settings per user. You can give permissions for particular directories or files. This server is also secure without being overly intrusive. Unlike wu-ftpd and many others, it doesn't do a chroot anywhere. It manages directories internally in a secure and fast way. This means the server doesn't need to run as root. Also since it doesn't ever run external programs, if the server does crash, the user won't be given any privliged access.
