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 Lesser 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 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) 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General Public License instead of this License.sbnc-1.3.9/Makefile.in0000664000175000017500000006215512216631001011442 00000000000000# Makefile.in generated by automake 1.11.3 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software # Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = .

You should usually not edit these files manually unless you know what you are doing. sbnc.conf --------- Option | Default Value | Purpose -------------------------------------------------------------------------------- system.port | N/A | the bouncer's main port system.sslport | N/A | the bouncer's main ssl port system.md5 | 1 | whether the users' passwords are stored using md5 hashes system.vhost | N/A | the default vhost for users who have not specified a vhost system.ip | 0.0.0.0 | the ip address which should be used for binding the main listener(s) system.motd | | the bouncer's motd (see /sbnc help motd) system.sendq | 10240 | the sendq size (in kB) system.dontmatchuser | 0 | whether to check the username if the user's ssl certificate already unambiguously matches a user system.users | | list of usernames system.modules.mod | N/A | list of module filenames User configuration files ------------------------ Option | Default Value | Purpose -------------------------------------------------------------------------------- user.password | N/A | the user's password (md5 hash if system.md5 == 1) user.admin | 0 | whether the user is an admin user.quitted | 0 | whether the user should stay disconnected from the irc server user.ts | 0 | whether to append a timestamp to the user's away reason user.port | 6667 | the port of the irc server for this user user.lock | 0 | whether the user is suspended user.seen | N/A | timestamp when the user was last seen user.delayjoin | 0 | whether to delay-join channels (usually just used by scripts) user.ssl | 0 | whether the user's server uses ssl user.ignsysnotices | 0 | whether the user should receive system notices user.lean | 0 | lean mode (see README.lean for details) user.quitaway | 0 | whether to use the user's /quit reason as the away reason user.automodes | | automodes user.dropmodes | | dropmodes user.away | | away reason (/away) user.awaynick | | away nick user.nick | | the user's nick user.realname | | the user's realname user.server | | the irc server's hostname user.ip | | the user's vhost user.channels | | comma-seperated list of channels user.suspend | | suspend reason for the user user.spass | | irc server password user.ident | the user's username | ident for the user user.awaymessage | | the user's away message (spammed to all chans, /ame style) user.channelsort | cts | how to order channels, options: cts (client ts), alpha (alphabetical), custom (using sort module handler) sbnc-1.3.9/INSTALL0000644000175000017500000000721411622514751010433 00000000000000Installing shroudBNC -------------------- First of all make sure that you have the following libraries (and development files) installed: - OpenSSL (if you're going to use SSL-encrypted connections; README.ssl contains more details about how to use SSL) - TCL (if you're going to use the tcl module, version 8.4 or later, earlier versions have not been tested) In order to compile and install shroudBNC you will have to use the 'configure' script which is included in the distribution of sbnc: $ ./configure If you are planning to install shroudBNC as root you will need to manually specify another prefix, e.g.: # ./configure --prefix=/usr/local Note: While loading TCL scripts shroudBNC will fall back to trying the $PREFIX/share/sbnc directory when a script isn't available in the user's configuration directory. Therefore it is NOT necessary to use absolute paths in the sbnc.tcl configuration file. The configure script will tell you which features have been enabled (e.g. SSL, TCL). In case any of the required libraries are missing you can now fix these errors and re-run the configure script. Afterwards you can build shroudBNC: $ make $ make install Unless you have manually specified another prefix "make install" will install shroudBNC in a directory named "sbnc" in your home directory: [gunnar@hermes ~]$ ls -l ~/sbnc total 6 drwxr-xr-x 2 gunnar gunnar 3 Aug 22 18:28 bin drwxr-xr-x 3 gunnar gunnar 3 Aug 22 18:28 lib -rwxr-xr-x 1 gunnar gunnar 243 Aug 22 18:28 sbnc drwxr-xr-x 3 gunnar gunnar 3 Aug 22 18:28 share [gunnar@hermes ~]$ Once you've compiled sbnc you will need to edit shroudBNC's configuration files: You can do that by simply starting shroudBNC in the installation directory: [gunnar@hermes ~]$ cd ~/sbnc [gunnar@hermes ~/sbnc]$ ./sbnc shroudBNC (version: 1.3alpha18 $Revision: 1158 $) - an object-oriented IRC bouncer Configuration directory: /usr/home/gunnar/sbnc [Sun August 22 2010 18:37:29]: Log system initialized. No valid configuration file has been found. A basic configuration file can be created for you automatically. Please answer the following questions: 1. Which port should the bouncer listen on (valid ports are in the range 1025 - 65535): 9000 2. What should the first user's name be? test Please note that passwords will not be echoed while you type them. 3. Please enter a password for the first user: 4. Please confirm your password by typing it again: Writing main configuration file... DONE Writing first user's configuration file... DONE Configuration has been successfully saved. Please restart shroudBNC now. [gunnar@hermes ~/sbnc]$ If you've installed shroudBNC as root you can simply start 'sbnc' in any directory (as a non-root user). shroudBNC will pick up any existing configuration directories (i.e. ~/sbnc, ~/.sbnc or the current working directory). If no configuration directory could be found it defaults to ~/.sbnc and asks you to create a config file. After creating the configuration files you can start shroudBNC: [gunnar@hermes ~/sbnc]$ ./sbnc shroudBNC (version: 1.3alpha18 $Revision: 1158 $) - an object-oriented IRC bouncer Configuration directory: /usr/home/gunnar/sbnc [Sun August 22 2010 18:42:53]: Log system initialized. [Sun August 22 2010 18:42:53]: Created main listener. [Sun August 22 2010 18:42:53]: Starting main loop. Daemonizing... DONE [gunnar@hermes ~/sbnc]$ You might want to edit the sbnc.tcl config file if you plan to use the TCL module. Load any scripts you want.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Additionally client certificates can be used for authenticating users. Why? ---- IRC is often used over insecure/unencrypted connections. While the problem of monitoring networks using packet sniffers might not be so obvious for (wired) LAN/WAN connections it becomes apparent when considering wireless connections, e.g. on a campus, where every other WLAN user can tap into your data transfers. Compiling shroudBNC with support for SSL ---------------------------------------- The "configure" script detects whether you have the necessary openssl libraries/headers and enables SSL support if possible. How to set up shroudBNC for SSL ------------------------------- shroudBNC supports two kinds of listeners: unencrypted and encrypted ones. During startup two configuration settings are read to determine whether the user wants unencrypted, encrypted listeners or both: system.port - sets the port for the unencrypted listener system.sslport - sets the port for the ssl-enabled listener If neither of those settings are used, shroudBNC falls back to creating an unencrypted listener on port 9000. You can remove the "system.port" setting from your configuration file if you just want an encrypted listener. These settings can be set in the bouncer's main configuration file: sbnc.conf Once you've enabled SSL shroudBNC expects to find the following files in your bouncer's directory: sbnc.crt - the public part of the server's key sbnc.key - the private part of the server's key The "openssl" utility can be used to create certificates. You can also use "make sslcert", which will generate an SSL certificate for you and install it in the appropriate directory. Please note that you will need to run shroudBNC in the foreground (i.e. using the --foreground parameter) if your private key has a passphrase. It is therefore recommended to remove the passphrase (after verifying that the file permissions are sufficiently secure). Client Certificates ------------------- Clients like irssi or mIRC which support client certificates can use such certificates for authentication. When you want to set the public key you are going to use for your bouncer account you have to log in using your client certificate AND your password (obviously because the bouncer doesn't know your public key yet). Once you're logged in you can use /sbnc savecert to tell shroudBNC that the client certificate you are currently using is to be trusted for public key authentication. Use /sbnc showcert to check that the certificate was saved correctly. You should now be able to log in using this client certificate. (You can also set your public key by putting a x509 certificate into your users/ directory. The file's name should be .crt, where is your username. However this requires a restart as shroudBNC only reads the certificate files during startup.) sbnc-1.3.9/Makefile.am0000644000175000017500000000226111441722154011430 00000000000000if BUILD_BNCTCL_MODULE BNCTCL_MODULE=bnctcl endif if BUILD_IDENTD_MODULE IDENTD_MODULE=bncidentd endif SUBDIRS=third-party src $(BNCTCL_MODULE) $(IDENTD_MODULE) php EXTRA_DIST=aclocal.m4 debian ssl.conf LICENSE LICENSE.Exceptions m4/tcl.m4 README README.copyright README.faq README.iface2 README.lean README.motd README.settings README.ssl sbnc-start sbnc_version.h ACLOCAL_AMFLAGS=-I m4 install: install-recursive @if [ "${exec_prefix}" = "${HOME}/sbnc" ]; then \ ${INSTALL_PROGRAM} sbnc-start ${exec_prefix}/sbnc; \ fi; sslcert: @if [ "${exec_prefix}" != "${HOME}/sbnc" ]; then \ echo "make sslcert can only be used when installing shroudBNC in your home directory.

What is happening? A: Either the password is wrong or your username is incorrect. Check your "sbnc.log" log file for details. You will also get that error when you tried to log in with a wrong password for a couple of times because shroudBNC temporarily blocks logins from your IP address (for about 10 minutes). --- Q: What are client certificates and what purpose do the commands savecert, delcert and showcert have? A: Client certificates are SSL certificates which the client sends to the server for password-less user authentication. For example, in mIRC you can set your client certificate using Ctrl-O -> Connect -> Options -> SSL. Once you are connected to shroudBNC using a client certificate you can use the savecert command to save the certificate in your private keychain. When you reconnect to your bouncer (without specifying a password) shroudBNC will recognise your certificate and allow you to log in. showcert can be used to view a list of currently trusted client certificates. Use delcert to remove a certificate. --- Q: What are listeners? A: Listeners are ports which can be used to connect to shroudBNC. When you initially create your shroudBNC configuration file you already created a main listener. Using the addlistener, dellistener and listeners commands you can create and remove additional listeners. --- Q: simul does not appear to work; what is wrong? A: You should keep in mind that simul is directly passing the command to the parser like any other IRC command. Therefore you will have to specify a valid IRC command. Examples: simul USER :jump - This will not work because /jump is not a valid command. simul USER :MSG -sBNC #test - This will not work either because on most clients /msg is actually an alias for PRIVMSG; MSG is not an IRC command simul USER :SBNC jump - This will work as expected. simul USER :PRIVMSG -sBNC :help - This too will work as expected. --- Q: Why do I get "Done." twice when using simul? A: The first "Done." is from the command you executed. The second one is from the simul command. --- Q: Why does something like simul USER :whois other-user not work? A: shroudBNC does not wait for a reply from the IRC server when executing simul commands. In fact, it could not possibly do that because shroudBNC would have to know what to expect from the IRC server for every IRC command. It can however directly respond to "sbnc" and "privmsg -sbnc" commands. --- Q: How do I load a TCL script for a specific user? A: If the TCL script is using eggdrop-style binds (bind, unbind) you can use the setctx (set context) command to specify the user which should be used for creating the binds: setctx "USERNAME" source "scripts/your-script.tcl" --- Q: My TCL script is using eggdrop users for authentication. How can I create those users on top of a shroudBNC user account? A: An admin can create, modify and delete "eggdrop" users using the eggtcl commands adduser, deluser, getuser, chattr, addhost and delhost. For example, to create an eggdrop user "test" for the shroudBNC user "bot" with flags +m and the host *!test@example.net you can use the following command: tcl :setctx bot; adduser test *!test@example.net; chattr test m sbnc-1.3.9/config.h.in0000664000175000017500000002372512216630777011443 00000000000000/* config.h.in.

It is capable of proxying IRC connections for multiple users. Using TCL scripts it can be extended. Installation ------------ Please read the INSTALL file for more details about how to install shroudBNC. Usage ----- Just connect to the bouncer using your favorite IRC client. You will have to set your username (i.e. e-mail address in most clients) to the accountname you've chosen for your bouncer account. If for some reason you can't change your client's username you can specify the username in the password setting (of the form username:password). Once you're connected you should type /msg -sBNC help to get a list of available commands. shroudBNC supports oidentd in order to provide unique idents for each bouncer user. You will need to enable ident-spoofing for the Unix account you're using to run shroudBNC if you want each user to have their own ident. Read oidentd's manual or http://wiki.shroudbnc.info/en/oidentd for more details. TCL --- The tcl module is automatically built and installed if the configure script was able to find the appropriate tcl libraries and headers. If the configure script was unable to find the TCL libraries/headers and you are sure that they are installed you might use the --with-tcl parameter to specify the location of the tclConfig.sh file manually; e.g.: ./configure --with-tcl=/usr/local/ActiveTcl/tcl8.4 Log files --------- shroudBNC automatically re-creates log files if they disappear during runtime. It also re-opens them if their inode of dev numbers change. Therefore rotating logs is as easy as moving the existing logs to a different location. Security -------- It is vital that you understand that any bouncer admin has access to: a) the shell account where the bouncer is running b) any user connections Using the TCL module any admin can perform shell commands (using the exec command) and send IRC commands for any user's connection. Thus you should choose your admins wisely. Do not load arbitrary scripts and make sure you understand any scripts you want to load. Credits ------- I'd like to thank all the beta testers who have been using shroudBNC so far. Feature requests and bug reports are welcome; please use our issue tracker at https://sourceforge.net/apps/mantisbt/sbnc/ In case you encounter problems while compiling and/or using shroudBNC you can contact us on IRC: Server: irc.quakenet.org / 6667 Channel: #sbnc Third Party Software -------------------- This product includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit (http://www.openssl.org/) For a more detailed list of third-party code in this project please refer to the README.copyright file. sbnc-1.3.9/configure.ac0000644000175000017500000002401611442241327011663 00000000000000# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.

The parameter .I name gives the query name as a NUL-terminated C string of period-separated labels optionally ending with a period; periods and backslashes within a label must be escaped with a backlash. The parameters .I dnsclass and .I type give the class and type of the query using the values defined in .BR . The parameter .I id gives a 16-bit identifier for the query. The parameter .I rd should be nonzero if recursion is desired, zero if not. The query will be placed in an allocated buffer, a pointer to which will be stored in the variable pointed to by .IR buf , and the length of which will be stored in the variable pointed to by .IR buflen . It is the caller's responsibility to free this buffer using \fIares_free_string(3)\fP when it is no longer needed. .SH RETURN VALUES .B ares_mkquery can return any of the following values: .TP 15 .B ARES_SUCCESS Construction of the DNS query succeeded. .TP 15 .B ARES_EBADNAME The query name .I name could not be encoded as a domain name, either because it contained a zero-length label or because it contained a label of more than 63 characters. .TP 15 .B ARES_ENOMEM Memory was exhausted. .SH SEE ALSO .BR ares_expand_name (3), .BR ares_free_string (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998, 2000 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares__close_sockets.c0000644000175000017500000000373011440771457017205 00000000000000 /* Copyright 1998 by the Massachusetts Institute of Technology. * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

If it returns successfully, \fBares_init\fP will set the variable pointed to by \fIchannelptr\fP to a handle used to identify the name service channel. The caller should invoke .BR ares_destroy (3) on the handle when the channel is no longer needed. .PP The \fBares_init_options\fP function also initializes a name service channel, with additional options useful for applications requiring more control over name service configuration. The \fIoptmask\fP parameter specifies which fields in the structure pointed to by \fIoptions\fP are set, as follows: .TP 18 .B ARES_OPT_FLAGS .B int \fIflags\fP; .br Flags controlling the behavior of the resolver. See below for a description of possible flag values. .TP 18 .B ARES_OPT_TIMEOUT .B int \fItimeout\fP; .br The number of seconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of \fItimeout\fP.) The default is five seconds. This option is being deprecated by \fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2. .TP 18 .B ARES_OPT_TIMEOUTMS .B int \fItimeout\fP; .br The number of milliseconds each name server is given to respond to a query on the first try. (After the first try, the timeout algorithm becomes more complicated, but scales linearly with the value of \fItimeout\fP.) The default is five seconds. Note that this option is specified with the same struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits that tell c-ares how to interpret the number. This option was added in c-ares 1.5.2. .TP 18 .B ARES_OPT_TRIES .B int \fItries\fP; .br The number of tries the resolver will try contacting each name server before giving up. The default is four tries. .TP 18 .B ARES_OPT_NDOTS .B int \fIndots\fP; .br The number of dots which must be present in a domain name for it to be queried for "as is" prior to querying for it with the default domain extensions appended. The default value is 1 unless set otherwise by resolv.conf or the RES_OPTIONS environment variable. .TP 18 .B ARES_OPT_PORT .B unsigned short \fIport\fP; .br The port to use for queries (both TCP and UDP), in network byte order. The default value is 53 (in network byte order), the standard name service port. .TP 18 .B ARES_OPT_SERVERS .B struct in_addr *\fIservers\fP; .br .B int \fInservers\fP; .br The list of IPv4 servers to contact, instead of the servers specified in resolv.conf or the local named. In order to allow specification of either IPv4 or IPv6 name servers, the .BR ares_set_servers(3) function must be used instead. .TP 18 .B ARES_OPT_DOMAINS .B char **\fIdomains\fP; .br .B int \fIndomains\fP; .br The domains to search, instead of the domains specified in resolv.conf or the domain derived from the kernel hostname variable. .TP 18 .B ARES_OPT_LOOKUPS .B char *\fIlookups\fP; .br The lookups to perform for host queries. .I lookups should be set to a string of the characters "b" or "f", where "b" indicates a DNS lookup and "f" indicates a lookup in the hosts file. .TP 18 .B ARES_OPT_SOCK_STATE_CB .B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write); .br .B void *\fIsock_state_cb_data\fP; .br A callback function to be invoked when a socket changes state. .I s will be passed the socket whose state has changed; .I read will be set to true if the socket should listen for read events, and .I write will be set to true if the socket should listen for write events. The value of .I sock_state_cb_data will be passed as the .I data argument. .PP The .I flags field should be the bitwise or of some subset of the following values: .TP 23 .B ARES_FLAG_USEVC Always use TCP queries (the "virtual circuit") instead of UDP queries. Normally, TCP is only used if a UDP query yields a truncated result. .TP 23 .B ARES_FLAG_PRIMARY Only query the first server in the list of servers to query. .TP 23 .B ARES_FLAG_IGNTC If a truncated response to a UDP query is received, do not fall back to TCP; simply continue on with the truncated response. .TP 23 .B ARES_FLAG_NORECURSE Do not set the "recursion desired" bit on outgoing queries, so that the name server being contacted will not try to fetch the answer from other servers if it doesn't know the answer locally. Be aware that ares will not do the recursion for you. Recursion must be handled by the application calling ares if \fIARES_FLAG_NORECURSE\fP is set. .TP 23 .B ARES_FLAG_STAYOPEN Do not close communications sockets when the number of active queries drops to zero. .TP 23 .B ARES_FLAG_NOSEARCH Do not use the default search domains; only query hostnames as-is or as aliases. .TP 23 .B ARES_FLAG_NOALIASES Do not honor the HOSTALIASES environment variable, which normally specifies a file of hostname translations. .TP 23 .B ARES_FLAG_NOCHECKRESP Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED response code or responses whose questions don't match the questions in the request. Primarily useful for writing clients which might be used to test or debug name servers. .SH RETURN VALUES .I ares_init or .I ares_init_options can return any of the following values: .TP 14 .B ARES_SUCCESS Initialization succeeded. .TP 14 .B ARES_EFILE A configuration file could not be read. .TP 14 .B ARES_ENOMEM The process's available memory was exhausted. .TP 14 .B ARES_ENOTINITIALIZED c-ares library initialization not yet performed. .SH NOTES When initializing from .B /etc/resolv.conf, .BR ares_init (3) reads the .I domain and .I search directives to allow lookups of short names relative to the domains specified. The .I domain and .I search directives override one another. If more that one instance of either .I domain or .I search directives is specified, the last occurence wins. For more information, please see the .BR resolv.conf (5) manual page. .SH SEE ALSO .BR ares_destroy(3), .BR ares_dup(3), .BR ares_library_init(3), .BR ares_set_servers(3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. .br Copyright (C) 2004-2010 by Daniel Stenberg. sbnc-1.3.9/third-party/c-ares/README.cares0000644000175000017500000000102711440771457015001 00000000000000c-ares ====== This package is based on ares 1.1.1 (written by Greg Hudson). I decided to fork and release a separate project since the ares author didn't want the improvements that were vital for our use of it. This package is dubbed 'c-ares' since I (Daniel Stenberg) wanted this for use within the curl project (hence the letter C) and it makes a nice pun. Also, c-ares is not API compatible with ares: a new name makes that more obvious to the public.

Once the program has called \fIares_library_cleanup(3)\fP it shall not make any further call to any c-ares function. .PP This function does not cancel any pending c-ares lookups or requests previously done. Program must use \fIares_cancel(3)\fP for this purpose. .PP .B This function is not thread safe. You have to call it once the program is about to terminate, but this call must be done once the program has terminated every single thread that it could have initiated. This is required to avoid potential race conditions in library deinitialization, and also due to the fact that \fIares_library_cleanup(3)\fP might call functions from other libraries that are thread unsafe, and could conflict with any other thread that is already using these other libraries. .PP Win32/64 application DLLs shall not call \fIares_library_cleanup(3)\fP from the DllMain function. Doing so will produce deadlocks and other problems. .SH AVAILABILITY This function was first introduced in c-ares version 1.7.0 along with the definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_CLEANUP\fP as an indication of the availability of this function. .PP Since the introduction of this function, it is absolutely mandatory to call it for any Win32/64 program using c-ares. .PP Non-Win32/64 systems can still use c-ares version 1.7.0 without calling \fIares_library_cleanup(3)\fP due to the fact that \fIcurrently\fP it is nearly a do-nothing function on non-Win32/64 platforms. .SH SEE ALSO .BR ares_library_init(3), .BR ares_cancel(3) .SH AUTHOR Yang Tse .PP Copyright 1998 by the Massachusetts Institute of Technology. .br Copyright (C) 2004-2009 by Daniel Stenberg. sbnc-1.3.9/third-party/c-ares/ares_mkquery.pdf0000644000175000017500000001144511622246250016222 00000000000000%PDF-1.4 %Çì¢ 5 0 obj <> stream xœXënãÆþ¯§ ?B-¬ÉÌðÞ¯¸µåÄ¢ ÞbA‘#‰DjIjõÒGÉ;öœ¹ð"Ë»ma‚Ä™3çò}ß9ÃO„QNþ™Ïl?ùö1$›fÂÈ÷ð¿™|špµ€˜lO¾K`Q„?$ë‰ÞÇI(Hèy$ÙOžëÇùòãýß~šrF÷cçiþ8ýGò×IèRîÆlHò‰ˆ8õ’¼LœŸ?8î‡)éö%ÿœ¸~@W¯|V߬S¦fŒ “$_bð…Æ>º3óDLÃÌÜw:‹k4Æp÷©‹ÎýïÃŒz ¶qzõ줵l>îùt”õ‰üNnªý¡j$IIS”›œÁƒ¦-ª’¼_,‰^µš ŒÙ œãz*<Ç"tÖ²V>=g< ‘ògùóâáÇåíR{¯Ô¡Sð‡¢ÌvÇ\’?§õ”‡`™ÇŽlèö/ʶ¶t7IÞ=;EÙ’Ñ"Ä'«Ê¦%Ù6­É;ãg¶”.£gT¦{‰Îê÷IV™â4˜0Ë®Š.¿! #Æ"»¿Õ¡ôÖ9u#[{'/›l—6ÍÅ#\—FýÒÿ÷ˆötãtBŽ†®ãÙð8™4;Dz)6¥ÌI³­êsû (ˆc³¿È/:?öñ+ΊÝPï#Šúò)õ9`ËžrìQÎÀÇ.F.ø;s¤8;1©p7{V½±˜Z7ÖãLŠqÊ.ϼË$‚ð­yLyŸÈ‹þ[–gÅó¨×i‡*Ð=µ„ cà0¬èYõ~¾¼y¼ý1¹}XŒéÞËI¶ç(‰(yl¥Ç)J÷D2Ô±ær&Œ¶€– ¡d},3%™–Ž´£×Š—¢ÝvbB¬˜ÐéÌçÄM käÖÀĶS.‡"¡ã⌮Eƒ|ÂuS˜Rp_cÑwûú}6L„ÐEÛ‘‚¦TGÄÂfÆÑyÁp]Ýбu$:FR |ñt7ƒ8öE™¶ÉÒ´5„Nª59Ⱥ¨òY#1Z|¸KWr×ê€Iw»‘eŽ‹MÎô†?©Ïº‡ßM€Ê‘‹‡£ V9œZæd•f¿4 5[H?n/J0  û#ˆáJÙdéŽ5Öqn€R€—GãR4çµpý˜²@\жäBy¶ý€_çÚQá»ü•vÙí3ú÷£·_ª(43_AJKúú…®~¸ÑÀbS«táÑX“v+ NˆPõýóTø”1á9éàJrùªKQڛž+(V ©ŽeÚâ!ý!ÑHü‰9¶}al®V qˆªÔž&}. 1C•Ü‘eœ\‡„{0Âp*˜û?0…]`‰šY¨/Ô& ˆëÛJÊ{ïÏä”áð>˜­Š–¹,Ûâ7Y“uU÷%ÀÍ^ ²âÁ¼ä‹Žœãd\j40ay½ ëFÃÆ5g#nu 'w9¦¬Êɺ"ÅšÔ2;Ö Š\€hŠZæWÄ>-«–ê> YŽ#¿— OÇt0{)v;´}Ø¥™À‘÷«LIÂJÑ<Š{WF,¡šA†t‚eÓt•ú<;X¡\“ ‚†yo+ò²-²mçNÓVµvÇ0Oô9ô…"]nÔFàM¥çRÁ Ñ÷íeuz« Dñ×›®Z6® ¢¹‡ÞU:Ø2nyG†àHkp~'Ë û+!ú¢#«S7xŸ…"Ìiô¥PL;÷µO#ˆnûJÑÛQÌ a ÞSÐ9¶%ôÆ–4ôݸ›[AÈ?²þÆÚ丄F ézàl±(0ds¨Ê™îp̧®wv7hŠU±+Úff]KÙ-à5åhÆãgØÔújàË`Ð× "4Öð-Àý‘ò£n•ýíg ’1 ” çe+‡-R±¬È®*7pv)e.súz`ÂÙ7ôúyéÙyœ'O ò÷)wÁù€;×wOó噺o%ÿÕtäbf­‹°º–í±F~f[ZF×1N€9ëA‘áÞÁ9ë Å]W ]–_°Iiìboúã™Ó3Žu«o©Ë§››ùr9na'SΠޗ꣞âLWì'¸æ˜eçÉÕ£¨?̪:iþÝTl\¿_t8¹†›èYE"‰#þX%ûA¯ƒQÈ@¤-n/ ‚€^×ö…L)8¨²{ʬçõx–Wû÷_ ƒ g%³ô7^@TfÙ; N ;ÑŽ’ý™‘=bUçVºµæùšìA} ±€ ¸ðãM%ÍpÈúRNMJ÷óû·j÷ìÜK0 eŠ¹ö]@FCä”ãºÎ¯[ðªÅÚ½¾›s·—óùœ\ß-Þ¾œi =À$õQ•b\Û@îu·3Åç«/ÜQ{îgDxõ¢pN6œDÇ'˜äCÕ^½.ÁGéâ ³OÃ7&"€±AÛJ~xx|õÒ$t¡f–,ß×ÃW ì}£u6?ŒÆPÞÍǼ©Ê+r›Û¦ž}ª¸¶‹ápg4 <éJÏ8 &A5ΓÉOð÷²óDendstream endobj 6 0 obj 2013 endobj 4 0 obj <> /Contents 5 0 R >> endobj 3 0 obj << /Type /Pages /Kids [ 4 0 R ] /Count 1 >> endobj 1 0 obj <> endobj 7 0 obj <>endobj 11 0 obj <> endobj 12 0 obj <> endobj 8 0 obj <> endobj 13 0 obj <> endobj 10 0 obj <> endobj 14 0 obj <> endobj 9 0 obj <> endobj 15 0 obj <>stream 2011-08-15T18:43:20+02:00 2011-08-15T18:43:20+02:00 groff version 1.20.1 Untitled endstream endobj 2 0 obj <>endobj xref 0 16 0000000000 65535 f 0000002337 00000 n 0000004274 00000 n 0000002278 00000 n 0000002118 00000 n 0000000015 00000 n 0000002098 00000 n 0000002402 00000 n 0000002523 00000 n 0000002811 00000 n 0000002671 00000 n 0000002443 00000 n 0000002473 00000 n 0000002605 00000 n 0000002755 00000 n 0000002876 00000 n trailer << /Size 16 /Root 1 0 R /Info 2 0 R /ID [<0A133EC13A7F46FC4017F2A8D543D968><0A133EC13A7F46FC4017F2A8D543D968>] >> startxref 4428 %%EOF sbnc-1.3.9/third-party/c-ares/ares_nowarn.h0000644000175000017500000000145411440771457015520 00000000000000#ifndef HEADER_CARES_NOWARN_H #define HEADER_CARES_NOWARN_H /* Copyright (C) 2010 by Daniel Stenberg * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

Change to c-ares source folder where Makefile.msvc file is located and run: > nmake -f Makefile.msvc This will build all c-ares libraries as well as three sample programs. Once the above command has finished a new folder named MSVCXX will exist below the folder where makefile.msvc is found. The name of the folder depends on the MSVC compiler version being used to build c-ares. Below the MSVCXX folder there will exist four folders named 'cares', 'ahost', 'acountry', and 'adig'. The 'cares' folder is the one that holds the c-ares libraries you have just generated, the other three hold sample programs that use the libraries. The above command builds four versions of the c-ares library, dynamic and static versions and each one in release and debug flavours. Each of these is found in folders named dll-release, dll-debug, lib-release, and lib-debug, which hang from the 'cares' folder mentioned above. Each sample program also has folders with the same names to reflect which library version it is using. How to build using Visual Studio 6 IDE -------------------------------------- A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc' folder to allow proper building of the library and sample programs. 1) Open the vc6aws.dsw workspace with MSVC6's IDE. 2) Select 'Build' from top menu. 3) Select 'Batch Build' from dropdown menu. 4) Make sure that the sixteen project configurations are 'checked'. 5) Click on the 'Build' button. 6) Once the sixteen project configurations are built you are done. Dynamic and static c-ares libraries are built in debug and release flavours, and can be located each one in its own subdirectory, dll-debug, dll-release, lib-debug and lib-release, all of them below the 'vc\cares' subdirectory. In the same way four executable versions of each sample program are built, each using its respective library. The resulting sample executables are located in its own subdirectory, dll-debug, dll-release, lib-debug and lib-release, below the 'vc\acountry', 'vc\adig' and 'vc\ahost'folders. These reference VC++ 6.0 configurations are generated using the dynamic CRT. How to build using Visual Studio 2003 or newer IDE -------------------------------------------------- First you have to convert the VC++ 6.0 reference workspace and project files to the Visual Studio IDE version you are using, following next steps: 1) Open vc\vc6aws.dsw with VS20XX. 2) Allow VS20XX to update all projects and workspaces. 3) Save ALL and close VS20XX. 4) Open vc\vc6aws.sln with VS20XX. 5) Select batch build, check 'all' projects and click 'build' button. Same comments relative to generated files and folders as done above for Visual Studio 6 IDE apply here. Relationship between c-ares library file names and versions ----------------------------------------------------------- c-ares static release library version files: libcares.lib -> static release library c-ares static debug library version files: libcaresd.lib -> static debug library c-ares dynamic release library version files: cares.dll -> dynamic release library cares.lib -> import library for the dynamic release library cares.exp -> export file for the dynamic release library c-ares dynamic debug library version files: caresd.dll -> dynamic debug library caresd.lib -> import library for the dynamic debug library caresd.exp -> export file for the dynamic debug library caresd.pdb -> debug symbol file for the dynamic debug library How to use c-ares static libraries ---------------------------------- When using the c-ares static library in your program, you will have to define preprocessor symbol CARES_STATICLIB while building your program, otherwise you will get errors at linkage stage.

The parameters .I abuf and .I alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into the variable pointed to by .IR host . The nameservers are stored into the .BR aliases field of the .IR host structure.

The parameters .I abuf and .I alen give the contents of the response. The parameters .IR addr , .IR addrlen , and .I family specify which address was queried for; they are not used to verify the response, merely used to fill in the address of the .BR "struct hostent" . The resulting .B struct hostent is stored in allocated memory and a pointer to it stored into the variable pointed to by .IR host . It is the caller's responsibility to free the resulting host structure using .BR ares_free_hostent (3) when it is no longer needed. .SH RETURN VALUES .B ares_parse_ptr_reply can return any of the following values: .TP 15 .B ARES_SUCCESS The response was successfully parsed. .TP 15 .B ARES_EBADRESP The response was malformatted. .TP 15 .B ARES_ENODATA The response did not contain an answer to the query. .TP 15 .B ARES_ENOMEM Memory was exhausted. .SH SEE ALSO .BR ares_gethostbyaddr (3), .BR ares_free_hostent (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_gethostbyaddr.30000644000175000017500000000566011440771457016775 00000000000000.\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" .\" Permission to use, copy, modify, and distribute this .\" software and its documentation for any purpose and without .\" fee is hereby granted, provided that the above copyright .\" notice appear in all copies and that both that copyright .\" notice and this permission notice appear in supporting .\" documentation, and that the name of M.I.T. not be used in .\" advertising or publicity pertaining to distribution of the .\" software without specific, written prior permission. .\" M.I.T. makes no representations about the suitability of .\" this software for any purpose.

The parameters .I addr and .I addrlen give the address as a series of bytes, and .I family gives the type of address. When the query is complete or has failed, the ares library will invoke \fIcallback\fP. Completion or failure of the query may happen immediately, or may happen during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP. .PP The callback argument .I arg is copied from the .B ares_gethostbyaddr argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The host lookup completed successfully. .TP 19 .B ARES_ENOTIMP The ares library does not know how to look up addresses of type .IR family . .TP 19 .B ARES_ENOTFOUND The address .I addr was not found. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP On successful completion of the query, the callback argument .I hostent points to a .B struct hostent containing the name of the host returned by the query. The callback need not and should not attempt to free the memory pointed to by .IR hostent ; the ares library will free it when the callback returns. If the query did not complete successfully, .I hostent will be .BR NULL . .SH SEE ALSO .BR ares_process (3), .BR ares_gethostbyname (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_parse_txt_reply.c0000644000175000017500000001273011440771457017432 00000000000000 /* Copyright 1998 by the Massachusetts Institute of Technology. * Copyright (C) 2009 by Jakub Hrozek * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

Socket descriptors will be set in the socket descriptor array pointed to by \fIsocks\fP. \fInumsocks\fP is the size of the given array in number of ints. This function can only return information about up to 16 sockets. If more are in use (however unlikely that is), they are simply not reported back. .SH RETURN VALUES \fBares_getsock\fP returns a bitmask for what actions to wait for on the different sockets. The ares.h header file provides these convenience macros to extract the information appropriately: .nf #define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about this many sockets */ #define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num))) #define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \ ARES_GETSOCK_MAXNUM))) .fi .SH NOTES This function was added in c-ares 1.3.1 .SH SEE ALSO .BR ares_timeout (3), .BR ares_fds (3), .BR ares_process (3) sbnc-1.3.9/third-party/c-ares/ahost.c0000644000175000017500000001123511440771457014311 00000000000000/* Copyright 1998 by the Massachusetts Institute of Technology. * * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

The resultant options and optmask are then able to be passed directly to ares_init_options. When the options are no longer needed, ares_destroy_options should be called to free any associated memory. .SH RETURN VALUES .B ares_save_options(3) can return any of the following values: .TP 15 .B ARES_SUCCESS The channel data was successfuly stored .TP 15 .B ARES_ENOMEM The memory was exhausted .TP 15 .B ARES_ENODATA The channel data identified by .IR channel were invalid. .SH NOTE Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it won't be extended to cover new functions. This function will remain functioning, but it can only return config data that can be represented in this config struct, which may no longer be the complete set of config options. \fBares_dup(3)\fP will not have that restriction. The ares_options struct can not handle potential IPv6 name servers the ares_channel might be configured to use. The \fBares_save_options(3)\fP function will only return IPv4 servers, if any. In order to retrieve all name servers an ares_channel might be using, the \fBares_get_servers(3)\fP function must be used instead. .SH SEE ALSO .BR ares_destroy_options (3), .BR ares_init_options (3), .BR ares_get_servers (3), .BR ares_dup (3) .SH AVAILABILITY ares_save_options(3) was added in c-ares 1.4.0 .SH AUTHOR Brad House .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_getsock.c0000644000175000017500000000444211440771457015646 00000000000000 /* Copyright (C) 2005 - 2010, Daniel Stenberg * * Permission to use, copy, modify, and distribute this software and its * documentation for any purpose and without fee is hereby granted, provided * that the above copyright notice appear in all copies and that both that * copyright notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in advertising or * publicity pertaining to distribution of the software without specific, * written prior permission.

The parameters .I abuf and .I alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into the variable pointed to by .IR host , if host is nonnull.

The .IR channel parameter is required, but no asynchronous queries are performed. Instead, the lookup is done via the same mechanism used to perform 'f' lookups (see the .I lookups options field in \fIares_init_options(3)\fP). The parameter .I name gives the hostname as a NUL-terminated C string, and .I family gives the desired type of address for the resulting host entry. .PP The return value indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The host lookup completed successfully and .I host now points to the result (and must be freed with \fIares_free_hostent(3)\fP). .TP 19 .B ARES_ENOTFOUND The hostname .I name was not found. .TP 19 .B ARES_EFILE There was a file I/O error while performing the lookup. .TP 19 .B ARES_ENOMEM Memory was exhausted. .PP On successful completion of the query, the pointer pointed to by .I host points to a .B struct hostent containing the address of the host returned by the lookup. The user must free the memory pointed to by .IR host when finished with it by calling \fIares_free_hostent(3)\fP. If the lookup did not complete successfully, .I host will be .BR NULL . .SH AVAILABILITY Added in c-ares 1.5.4 .SH SEE ALSO .BR ares_gethostbyname (3), .BR ares_free_hostent (3), .BR ares_init_options (3) .SH AUTHOR Brad Spencer .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_dns.h0000644000175000017500000001107511440771457015000 00000000000000 /* Copyright 1998 by the Massachusetts Institute of Technology. * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

It is intended for applications which need to perform DNS queries without blocking, or need to perform multiple DNS queries in parallel. The primary examples of such applications are servers which communicate with multiple clients and programs with graphical user interfaces. The full source code is available in the 'c-ares' release archives, and in a git repository: http://github.com/bagder/c-ares If you find bugs, correct flaws, have questions or have comments in general in regard to c-ares (or by all means the original ares too), get in touch with us on the c-ares mailing list: http://cool.haxx.se/mailman/listinfo/c-ares c-ares is of course distributed under the same MIT-style license as the original ares. You'll find all c-ares details and news here: http://c-ares.haxx.se/ NOTES FOR C-ARES HACKERS The following notes apply to c-ares version 1.7.0 and later. * The distributed ares_build.h file is only intended to be used on systems which can not run the also distributed configure script. * The distributed ares_build.h file is generated as a copy of ares_build.h.dist when the c-ares source code distribution archive file is originally created. * If you check out from git on a non-configure platform, you must run the appropriate buildconf* script to set up ares_build.h and other local files before being able of compiling the library. * On systems capable of running the configure script, the configure process will overwrite the distributed ares_build.h file with one that is suitable and specific to the library being configured and built, this new file is generated from the ares_build.h.in template file. * If you intend to distribute an already compiled c-ares library you _MUST_ also distribute along with it the generated ares_build.h which has been used to compile it. Otherwise the library will be of no use for the users of the library that you have built. It is _your_ responsibility to provide this file. No one at the c-ares project can know how you have built the library. * File ares_build.h includes platform and configuration dependent info, and must not be modified by anyone. Configure script generates it for you. * We cannot assume anything else but very basic compiler features being present. While c-ares requires an ANSI C compiler to build, some of the earlier ANSI compilers clearly can't deal with some preprocessor operators. * Newlines must remain unix-style for older compilers' sake. * Comments must be written in the old-style /* unnested C-fashion */ sbnc-1.3.9/third-party/c-ares/ares_parse_ns_reply.pdf0000644000175000017500000001026111622246251017546 00000000000000%PDF-1.4 %Çì¢ 5 0 obj <> stream xœWÛnÛF}×W,Ї’F´Ù ——4êÄJê–]‰NØ…@Q+‹E:¼Xõ?ôWúÝåMtŒ…mØâ.çræÌ™ñWD0ED}5¿ãýäõÂC÷å„ Oðs?ù:¡új~Å{ô>„K¾zn'æ=Š<†<ÇAá~rk.fËÕµ0øk9[Í—«ÅìúÂþ#üŒ¹8àp3a”cÏEáab}¹³øšÃ?'Ì#˜;æÞí±JHs_[œÌh€Â‚ (×”{æM¹«lXóSe–¨{T`pcÛºœ©ç}>Œ`‡xhJ™:&*º[+*d¹zˆŠR®²rUȇô ýƒ®m°D¨ãZêEÈT9üy6_¢¯µ,žP¾EÕÓƒDð ÉôÙ./+™U:úQÌ.8v±¯#[~™_]/Ï—&¾ ‰O_a–’,NëDo£Â¦KK–x÷Î`­-]L“[ \££KƒtlêcB<ßRáßYqž•ª³2¹ÏäÅ»¨@'M°”´e<ì°¶>ÑÚfĪ·ú⯆¾ëaáÚþ*é áaÏ'Äoiïƒbîíq”Êì ° •Z»êpÊ $@…¥áé =Žñ7Õaªn ã0ĸ8ŽÛb‹Ã¾ùìÑ‚j˜: H#ü!7ÚËJå¨^àì‰oÒnРxát¼É6c^u'xÆ«P.Útï5_Ae¨0œ¼ã,hD£~<‡9zxÑܹ…l4—B­Ôªí©P}B…¢‡z\§JJTVy]˜d(JÓ<Ž*ø°—ûª™A¥´RæãÀla&ãó!‡ŠÊBU;©zkðQ¹´™ŠÀ< ]­S‰Ìýº¿~w=#Ð/Þ¨a„q6¬>dÂÅ7jϱï:]ÃI”A•KYáp(øRñ +u˲ÜÖ)¬, }äT[êÐÖgïm¦¬8ö<¸¡õ}Î÷QºÍ‹}TUÿáµq:¿:kD8Ðh»jçkÑœRl4ø4Dý’7਱Z#ŽWº£à6É(XiuŽ”Ôªïò`dSµ‘“¶+K¸õ}!_Î._.Ì¥‘ð#T¤Þ'•ƒ¿vQ]Ž°éVJ‡Kâl†N/–W//‰Çœ7‰×̹t ×½ùê›PÏÞc“Ï”a°Üö©ƒHô«”^ÞMA êg»;LLµ]0½nïÌåí ¹Z<›ÞwyÀïE<Ë`œ¡Ïi´AgIV§²Œkôö>ãMûùçÈVJ®Úñ1)"çûw¯lOk¹ª‘} R#¬Ïç‹Sôi¿Þ¡]U=¼yýúp89,Á>bþ#h 4‹8Ãj8óæô£\u `œÖרɊª'³pò|ý A€{endstream endobj 6 0 obj 1477 endobj 4 0 obj <> /Contents 5 0 R >> endobj 3 0 obj << /Type /Pages /Kids [ 4 0 R ] /Count 1 >> endobj 1 0 obj <> endobj 7 0 obj <>endobj 11 0 obj <> endobj 12 0 obj <> endobj 8 0 obj <> endobj 13 0 obj <> endobj 10 0 obj <> endobj 9 0 obj <> endobj 14 0 obj <>stream 2011-08-15T18:43:21+02:00 2011-08-15T18:43:21+02:00 groff version 1.20.1 Untitled endstream endobj 2 0 obj <>endobj xref 0 15 0000000000 65535 f 0000001801 00000 n 0000003666 00000 n 0000001742 00000 n 0000001582 00000 n 0000000015 00000 n 0000001562 00000 n 0000001866 00000 n 0000001987 00000 n 0000002203 00000 n 0000002135 00000 n 0000001907 00000 n 0000001937 00000 n 0000002069 00000 n 0000002268 00000 n trailer << /Size 15 /Root 1 0 R /Info 2 0 R /ID [<7479F4C21C871FD5482D4AFA849C16A5><7479F4C21C871FD5482D4AFA849C16A5>] >> startxref 3820 %%EOF sbnc-1.3.9/third-party/c-ares/ares__timeval.c0000644000175000017500000000602511440771457016006 00000000000000 /* Copyright (C) 2008 by Daniel Stenberg et al * * Permission to use, copy, modify, and distribute this software and its * documentation for any purpose and without fee is hereby granted, provided * that the above copyright notice appear in all copies and that both that * copyright notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in advertising or * publicity pertaining to distribution of the software without specific, * written prior permission.

The parameters .I abuf and .I alen give the contents of the response. The result is stored in allocated memory and a pointer to it stored into the variable pointed to by .IR host , if host is nonnull. It is the caller's responsibility to free the resulting host structure using .BR ares_free_hostent (3) when it is no longer needed. .PP If .IR addrttls and .IR naddrttls are both nonnull, then up to *naddrttls .BR "struct ares_addr6ttl" records are stored in the array pointed to by addrttls, and then *naddrttls is set to the number of records so stored. Note that the memory for these records is supplied by the caller. .SH RETURN VALUES .B ares_parse_aaaa_reply can return any of the following values: .TP 15 .B ARES_SUCCESS The response was successfully parsed. .TP 15 .B ARES_EBADRESP The response was malformatted. .TP 15 .B ARES_ENODATA The response did not contain an answer to the query. .TP 15 .B ARES_ENOMEM Memory was exhausted. .SH SEE ALSO .BR ares_gethostbyname (3), .BR ares_free_hostent (3) .SH AUTHOR Dominick Meglio .br Copyright 2005 by Dominick Meglio. sbnc-1.3.9/third-party/c-ares/Makefile.am0000644000175000017500000001306711440771457015070 00000000000000AUTOMAKE_OPTIONS = foreign nostdinc ACLOCAL_AMFLAGS = -I m4 # Specify our include paths here, and do it relative to $(top_srcdir) and # $(top_builddir), to ensure that these paths which belong to the library # being currently built and tested are searched before the library which # might possibly already be installed in the system. # # When using the low-level hard-hacking memory leak tracking code from # libcurl the generated curl/curlbuild.h file must also be reachable. # Using the libcurl lowlevel code from within c-ares library is ugly and # only works when c-ares is built and linked with a similarly debug-build # libcurl, but we do this anyway for convenience. # # $(top_builddir)/../include/curl for generated curlbuild.h included from curl.h # $(top_builddir)/../include is for libcurl's generated curl/curlbuild.h file # $(top_srcdir)/../include is for libcurl's external include files # $(top_builddir)/../lib is for libcurl's generated lib/curl_config.h file # $(top_srcdir)/../lib is for libcurl's lib/setup.h and other "private" files # $(top_builddir) is for c-ares's generated ares_config.h file # $(top_srcdir) is for c-ares's ares_setup.h and other "c-ares-private" files if CURLDEBUG INCLUDES = -I$(top_builddir)/../include/curl \ -I$(top_builddir)/../include \ -I$(top_srcdir)/../include \ -I$(top_builddir)/../lib \ -I$(top_srcdir)/../lib \ -I$(top_builddir) \ -I$(top_srcdir) else INCLUDES = -I$(top_builddir) \ -I$(top_srcdir) endif lib_LTLIBRARIES = libcares.la man_MANS = $(MANPAGES) MSVCFILES = vc/vc6aws.dsw vc/acountry/vc6acountry.dsp vc/adig/vc6adig.dsp \ vc/ahost/vc6ahost.dsp vc/cares/vc6cares.dsp vc/cares/vc6cares.dsw if CURLDEBUG PROGS = else PROGS = ahost adig acountry endif noinst_PROGRAMS =$(PROGS) # adig and ahost are just sample programs and thus not mentioned with the # regular sources and headers EXTRA_DIST = AUTHORS CHANGES README.cares Makefile.inc Makefile.dj \ Makefile.m32 Makefile.netware Makefile.msvc $(man_MANS) $(MSVCFILES) \ config-win32.h RELEASE-NOTES libcares.pc.in buildconf get_ver.awk maketgz \ TODO ares_build.h.in $(PDFPAGES) cares.rc README.msvc $(CSOURCES) $(HHEADERS) CLEANFILES = $(PDFPAGES) $(HTMLPAGES) DISTCLEANFILES = ares_build.h pkgconfigdir = $(libdir)/pkgconfig pkgconfig_DATA = libcares.pc VER=-version-info 2:0:0 # This flag accepts an argument of the form current[:revision[:age]].

The parameter .I tv must point to a writable buffer of type .BR "struct timeval" . It is valid for .I maxtv and .I tv to have the same value. .PP If no queries have timeouts pending sooner than the given maximum timeout, .B ares_timeout returns the value of .IR maxtv; otherwise .B ares_timeout stores the appropriate timeout value into the buffer pointed to by .I tv and returns the value of .IR tv . .SH SEE ALSO .BR ares_fds (3), .BR ares_process (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_build.h.in0000644000175000017500000000777611440771457015735 00000000000000#ifndef __CARES_BUILD_H #define __CARES_BUILD_H /* Copyright (C) 2009 by Daniel Stenberg et al * * Permission to use, copy, modify, and distribute this software and its * documentation for any purpose and without fee is hereby granted, provided * that the above copyright notice appear in all copies and that both that * copyright notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in advertising or * publicity pertaining to distribution of the software without specific, * written prior permission.

The name server linked list pointer argument may be the result of a previous call to \fBares_get_servers(3)\fP or a linked list of ares_addr_node structs setup by other means. This function replaces any potentially previously configured name servers with the ones given in the linked list. So, in order to configure a channel with more than one name server all the desired ones must be specified in a single list. \fBares_set_servers(3)\fP does not take ownership of the linked list argument. The caller is responsible for freeing the linked list when no longer needed. This function is capable of handling IPv4 and IPv6 name server addresses simultaneously, rendering \fBares_init_options(3)\fP with optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for IPv4-only name server usage. .SH RETURN VALUES .B ares_set_servers(3) may return any of the following values: .TP 15 .B ARES_SUCCESS The name servers configuration was successfuly initialized. .TP 15 .B ARES_ENOMEM The process's available memory was exhausted. .TP 15 .B ARES_ENODATA The channel data identified by .IR channel was invalid. .TP 15 .B ARES_ENOTINITIALIZED c-ares library initialization not yet performed. .SH SEE ALSO .BR ares_get_servers (3), .BR ares_init_options (3), .BR ares_dup(3) .SH AVAILABILITY ares_set_servers(3) was added in c-ares 1.7.1 .SH AUTHOR Implementation of this function and associated library internals are based on code, comments and feedback provided in November and December of 2008 by Daniel Stenberg, Gregor Jasny, Phil Blundell and Yang Tse, December 2009 by Cedric Bail, February 2010 by Jakub Hrozek.

The function is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will translate the address either by executing a host query on the name service channel identified by .IR channel or it will attempt to resolve it locally if possible. The parameters .I sa and .I len give the address as a sockaddr structure, and .I flags gives the options that the function will use. Valid flags are listed below: .TP 19 .B ARES_NI_NOFQDN Only the nodename portion of the FQDN is returned for local hosts. .TP 19 .B ARES_NI_NUMERICHOST The numeric form of the hostname is returned rather than the name. .TP 19 .B ARES_NI_NAMEREQD An error is returned if the hostname cannot be found in the DNS. .TP 19 .B ARES_NI_NUMERICSERV The numeric form of the service is returned rather than the name. .TP 19 .B ARES_NI_TCP The service name is to be looked up for the TCP protocol. .TP 19 .B ARES_NI_UDP The service name is to be looked up for the UDP protocol. .TP 19 .B ARES_NI_SCTP The service name is to be looked up for the SCTP protocol. .TP 19 .B ARES_NI_DCCP The service name is to be looked up for the DCCP protocol. .TP 19 .B ARES_NI_NUMERICSCOPE The numeric form of the scope ID is returned rather than the name. .TP 19 .B ARES_NI_LOOKUPHOST A hostname lookup is being requested. .TP 19 .B ARES_NI_LOOKUPSERVICE A service name lookup is being requested. .PP When the query is complete or has failed, the ares library will invoke \fIcallback\fP. Completion or failure of the query may happen immediately, or may happen during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP. .PP The callback argument .I arg is copied from the .B ares_getnameinfo argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The host lookup completed successfully. .TP 19 .B ARES_ENOTIMP The ares library does not know how to look up addresses of type .IR family . .TP 19 .B ARES_ENOTFOUND The address .I addr was not found. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .TP 19 .B ARES_EBADFLAGS The .I flags parameter contains an illegal value. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP On successful completion of the query, the callback argument .I node contains a string representing the hostname (assuming .B ARES_NI_LOOKUPHOST was specified). Additionally, .I service contains a string representing the service name (assuming .B ARES_NI_LOOKUPSERVICE was specified). If the query did not complete successfully, or one of the values was not requested, .I node or .I service will be .BR NULL . .SH SEE ALSO .BR ares_process (3), .BR ares_getaddrinfo (3) .SH AUTHOR Dominick Meglio .br Copyright 2005 by Dominick Meglio. sbnc-1.3.9/third-party/c-ares/ltmain.sh0000644000175000017500000105204012216630752014641 00000000000000 # libtool (GNU libtool) 2.4.2 # Written by Gordon Matzigkeit , 1996 # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2003, 2004, 2005, 2006, # 2007, 2008, 2009, 2010, 2011 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.

The argument .I encoded gives the beginning of the encoded domain name, and the arguments .I abuf and .I alen give the containing message buffer (necessary for the processing of indirection pointers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the variable pointed to by .IR s .

See http://github.com/bagder/c-ares * March 5, 2010 (Daniel Stenberg) - Daniel Johnson provided fixes for building with the clang compiler. * March 5, 2010 (Yang Tse) - Added IPv6 name servers support. Implementation has been based on code, comments and feedback provided November and December of 2008 by Daniel Stenberg, Gregor Jasny, Phil Blundell and myself, December 2009 by Cedric Bail, and February 2010 by Jakub Hrozek on the c-ares mailing list. On March I reviewed all that, selected the best of each, and adjusted or extended parts of it to make the best fit. The external and visible result of all this is that two new functions are added to the external API, ares_get_servers() and ares_set_servers(), which becomes now the preferred way of getting and setting name servers for any ares channel as these support both IPv4 and IPv6 name servers. In order to not break ABI compatibility, ares_init_options() with option mask ARES_OPT_SERVERS and ares_save_options() may still be used in code which is intended to run on IPv4-only stacks. But remember that these functions do not support IPv6 name servers. This implies that if the user is capable of defining or providing an IPv6 name server, and the app is using ares_init_options() or ares_save_options() at some point to handle the name servers, the app will likely lose IPv6 name servers. * January 28, 2010 (Daniel Stenberg) - Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't check for broken connections like ares_process() did. Based on that, I merged the two functions into a single generic one with two front-ends. * December 29, 2009 (Yang Tse) - Laszlo Tamas Szabo adjusted Makefile.msvc compiler options so that where run-time error checks enabling compiler option /GZ was used it is replaced with equivalent /RTCsu for Visual Studio 2003 and newer versions. Option /GX is replaced with equivalent /EHsc for all versions. Also fixed socket data type for internal configure_socket function. * December 21, 2009 (Yang Tse) - Ingmar Runge noticed that Windows config-win32.h configuration file did not include a definition for HAVE_CLOSESOCKET which resulted in function close() being inappropriately used to close sockets. Version 1.7.0 (Nov 30, 2009) * November 26, 2009 (Yang Tse) - Larry Lansing fixed ares_parse_srv_reply to properly parse replies which might contain non-SRV answers, skipping over potential non-SRV ones such as CNAMEs. * November 23, 2009 (Yang Tse) - Changed naming convention for c-ares libraries built with MSVC, details and build instructions provided in README.msvc file. * November 22, 2009 (Yang Tse) - Jakub Hrozek fixed more function prototypes in man pages to sync them with the ones declared in ares.h - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and ares_addr6ttl in order to prevent name space pollution, along with necessary changes to code base and man pages.This change does not break ABI, there is no need to recompile existing applications. But existing applications using these structs with the old name will need source code adjustments when recompiled using c-ares 1.7.0. * November 21, 2009 (Yang Tse) - Added manifest stuff to Makefile.msvc. * November 20, 2009 (Yang Tse) - Fixed several function prototypes in man pages that were out of sync with the ones declared in ares.h. Added ares_free_data() along with man page. Updated ares_parse_srv_reply() and ares_parse_txt_reply() with changes from Jakub Hrozek making these now return linked lists instead of arrays, and merging the ares_free_data() adjustments. * November 10, 2009 (Yang Tse) - Updated MSVC 6.0 project files to match settings from Makefile.msvc. * November 9, 2009 (Yang Tse) - Makefile.msvc is now the reference method to build c-ares and sample programs with any MSVC compiler or MS Visual Studio version. If no option or target are specified it builds dynamic and static c-ares libraries in debug and release flavours and also builds all sample programs using each of the different c-ares libraries. * November 2, 2009 (Yang Tse) - Renamed c-ares setup.h to ares_setup.h * October 31, 2009 (Yang Tse) - Symbol hiding configure options are named now --enable-symbol-hiding and --disable-symbol-hiding in an attempt to make them less ambiguous. * October 30, 2009 (Yang Tse) - Many fixes for ares_parse_txt_reply() * October 29, 2009 (Daniel Stenberg) - Jakub Hrozek added ares_parse_txt_reply() for TXT parsing * October 29, 2009 (Yang Tse) - Updated MSVC 6.0 workspace and project files that allows building dynamic and static c-ares libraries in debug and release flavours. Additionally each of the three sample programs is built against each of the four possible c-ares libraries, generating all this a total number of 12 executables and 4 libraries. * October 28, 2009 (Yang Tse) - Initial step towards the ability to reduce c-ares exported symbols when built as a shared library based on the 'visibility' attribute for GNUC and Intel compilers and based on __global for Sun compilers, taking also in account __declspec function decoration for Win32 and Symbian DLL's. * October 27, 2009 (Yang Tse) - Fixed Pelles C Win32 target compilation issues. * October 23, 2009 (Yang Tse) - John Engelhart noticed an unreleased problem relative to a duplicate ARES_ECANCELLED error code value and missing error code description. * October 7, 2009 (Yang Tse) - Overhauled ares__get_hostent() Fixing out of bounds memory overwrite triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts file. Validating requested address family. Ensuring that failures always return a NULL pointer. Adjusting header inclusions. * October 6, 2009 (Yang Tse) - Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak. * September 29, 2009 (Yang Tse) - Make configure script also check if _REENTRANT definition is required to make errno available as a preprocessor macro. * September 7, 2009 (Yang Tse) - Add T_SRV portability check to ares_parse_srv_reply.c * 4 Sep 2009 (Daniel Stenberg) - Jakub Hrozek added ares_parse_srv_reply() for SRV parsing * 3 Aug 2009 (Daniel Stenberg) - Joshua Kwan fixed the init routine to fill in the defaults for stuff that fails to get inited by other means. This fixes a case of when the c-ares init fails when internet access is fone. - Timo Teras changed the reason code used in the resolve callback done when ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to better allow the callback to know what's happening. * 14 Jul 2009 (Guenter Knauf) - renamed generated config.h to ares_config.h to avoid any future clashes with config.h from other projects. * June 20 2009 (Yang Tse) - Refactor how libraries are checked for connect() function in configure script and check for connect() as it is done for other functions. * June 19 2009 (Yang Tse) - Make sclose() function-like macro definition used to close a socket, now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL config file preprocessor definitions * June 18 2009 (Yang Tse) - Add CloseSocket camel case function check for configure script. * June 17 2009 (Yang Tse) - Check for socket() and closesocket() as it is done for other functions in configure script. * June 11 2009 (Yang Tse) - Modified buildconf so that when automake runs it copies missing files instead of symlinking them. * June 8 2009 (Yang Tse) - Removed buildconf.bat from release and daily snapshot archives. This file is only for CVS tree checkout builds. * May 26 2009 (Yang Tse) - Added --enable-curldebug configure option to enable and disable building with the low-level curl debug memory tracking 'feature' to allow decoupled setting from --enable-debug, allowing again to build c-ares independently out of the CVS tree. For the c-ares library option --enable-debug enables debug build features which are _not_ related with memory tracking. For the c-ares library when --enable-debug is given it does not enable the memory tracking feature. If you wish to enable the curl debug memory tracking you must use configure option --enable-curldebug explicitily to do so. Internally, definition of preprocessor symbol DEBUGBUILD restricts code which is only compiled for debug enabled builds. And symbol CURLDEBUG is used to differentiate code which is _only_ used for memory tracking. Make ares_init(), ares_dup() and ares_init_options() fail returning ARES_ENOTINITIALIZED if library initialization has not been performed calling ares_library_init(). * May 20 2009 (Yang Tse) - Added ares_library_init() and ares_library_cleanup() man pages. * May 19 2009 (Yang Tse) - Introduced ares_library_init() and ares_library_cleanup() functions. This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets using c-ares 1.7.0 can still survive without calling these functions. Read all the details on ares_library_init(3) and ares_library_cleanup(3) man pages that are included. curl/libcurl 7.19.5 is fully compatible with c-ares 1.7.0 on all systems. In order to use c-ares 1.7.0 with curl/libcurl on Win32/64 systems it is required that curl/libcurl is 7.19.5 or newer. In other words, it is not possible on Win32/64 to use c-ares 1.7.0 with a curl/libcurl version less than 7.19.5 * May 11 2009 (Daniel Stenberg) - Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to only expose functions starting with ares_. * May 7 2009 (Yang Tse) - Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition attempt in generated config.h * May 2 2009 (Yang Tse) - Use a build-time configured ares_socklen_t data type instead of socklen_t. * April 21 2009 (Yang Tse) - Moved potential inclusion of system's malloc.h and memory.h header files to setup_once.h. Inclusion of each header file is based on the definition of NEED_MALLOC_H and NEED_MEMORY_H respectively. * March 11 2009 (Yang Tse) - Japheth Cleaver fixed acountry.c replacing u_long with unsigned long. * February 20 2009 (Yang Tse) - Do not halt compilation when using VS2008 to build a Windows 2000 target. * February 3 2009 (Phil Blundell) - If the server returns garbage or nothing at all in response to an AAAA query, go on and ask for A records anyway. * January 31 2009 (Daniel Stenberg) - ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving either AF_INET6 or AF_INET. It works by accepting any of the looksups in the hosts file, and it resolves the AAAA field with a fallback to A. * January 14 2009 (Daniel Stenberg) - ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it now declares the private struct ares_in6_addr for all systems instead of relying on one possibly not present in the system. * January 13 2009 (Phil Blundell) - ares__send_query() now varies the retry timeout pseudo-randomly to avoid packet storms when several queries were started at the same time. * January 11 2009 (Daniel Stenberg) - Phil Blundell added the internal function ares__expand_name_for_response() that is now used by the ares_parse_*_reply() functions instead of the ares_expand_name() simply to easier return ARES_EBADRESP for the cases where the name expansion fails as in responses that really isn't expected. Version 1.6.0 (Dec 9, 2008) * December 9 2008 (Gisle Vanem) Fixes for Win32 targets using the Watt-32 tcp/ip stack. * Dec 4 2008 (Daniel Stenberg) Gregor Jasny provided the patch that introduces ares_set_socket_callback(), and I edited it to also get duped by ares_dup(). * Dec 3 2008 (Daniel Stenberg) API changes: I made sure the public ares_config struct looks like before and yet it supports the ROTATE option thanks to c-ares now storing the "optmask" internally. Thus we should be ABI compatible with the past release(s) now. My efforts mentioned below should not break backwards ABI compliance. Here's how I suggest we proceed with the API: ares_init() will be primary "channel creator" function. ares_init_options() will continue to work exactly like now and before. For starters, it will be the (only) way to set the existing options. ares_save_options() will continue to work like today, but will ONLY save options that you can set today (including ARES_OPT_ROTATE actually) but new options that we add may not be saved with this. Instead we introduce: ares_dup() that instead can make a new channel and clone the config used from an existing channel. It will then clone all config options, including future new things we add. ares_set_*() style functions that set (new) config options. As a start we simply add these for new functionality, but over time we can also introduce them for existing "struct ares_options" so that we can eventually deprecate the two ares_*_options() functions. ares_get_*() style functions for extracting info from a channel handle that should be used instead of ares_save_options(). * Nov 26 2008 (Yang Tse) - Brad Spencer provided changes to allow buildconf to work on OS X. - Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a buffer to shrink instead of expand if a reply contained 8 or more records. * Nov 25 2008 (Yang Tse) - In preparation for the upcomming IPv6 nameservers patch, the internal ares_addr union is now changed into an internal struct which also holds the address family. * Nov 19 2008 (Daniel Stenberg) - Brad Spencer brought the new function ares_gethostbyname_file() which simply resolves a host name from the given file, using the regular hosts syntax. * Nov 1 2008 (Daniel Stenberg) - Carlo Contavalli added support for the glibc "rotate" option, as documented in man resolv.conf: causes round robin selection of nameservers from among those listed. This has the effect of spreading the query load among all listed servers, rather than having all clients try the first listed server first every time. You can enable it with ARES_OPT_ROTATE * Oct 21 2008 (Yang Tse) Charles Hardin added handling of EINPROGRESS for UDP connects. * Oct 18 2008 (Daniel Stenberg) Charles Hardin made adig support a regular numerical dotted IP address for the -s option as well. * Oct 7 2008 (Yang Tse) - Added --enable-optimize configure option to enable and disable compiler optimizations to allow decoupled setting from --enable-debug. * Oct 2 2008 (Yang Tse) - Added --enable-warnings configure option to enable and disable strict compiler warnings to allow decoupled setting from --enable-debug. * Sep 17 2008 (Yang Tse) - Code reorganization to allow internal/private use of "nameser.h" to any system that lacks arpa/nameser.h or arpa/nameser_compat.h header files. * Sep 16 2008 (Yang Tse) - Code reorganization to allow internal/private use of ares_writev to any system that lacks the writev function. * Sep 15 2008 (Yang Tse) - Code reorganization to allow internal/private use of ares_strcasecmp to any system that lacks the strcasecmp function. - Improve configure detection of some string functions. * Sep 11 2008 (Yang Tse) - Code reorganization to allow internal/private use of ares_strdup to any system that lacks the strdup function. Version 1.5.3 (Aug 29, 2008) * Aug 25 2008 (Yang Tse) - Improvement by Brad House: This patch addresses an issue in which a response could be sent back to the source port of a client from a different address than the request was made to. This is one form of a DNS cache poisoning attack. The patch simply uses recvfrom() rather than recv() and validates that the address returned from recvfrom() matches the address of the server we have connected to. Only necessary on UDP sockets as they are connection-less, TCP is unaffected. - Fix by George Neill: Fixed compilation of acountry sample application failure on some systems. * Aug 4 2008 (Daniel Stenberg) - Fix by Tofu Linden: The symptom: * Users (usually, but not always) on 2-Wire routers and the Comcast service and a wired connection to their router would find that the second and subsequent DNS lookups from fresh processes using c-ares to resolve the same address would cause the process to never see a reply (it keeps polling for around 1m15s before giving up). The repro: * On such a machine (and yeah, it took us a lot of QA to find the systems that reproduce such a specific problem!), do 'ahost www.secondlife.com', then do it again. The first process's lookup will work, subsequent lookups will time-out and fail. The cause: * init_id_key() was calling randomize_key() *before* it initialized key->state, meaning that the randomness generated by randomize_key() is immediately overwritten with deterministic values. (/dev/urandom was also being read incorrectly in the c-ares version we were using, but this was fixed in a later version.) * This makes the stream of generated query-IDs from any new c-ares process be an identical and predictable sequence of IDs. * This makes the 2-Wire's default built-in DNS server detect these queries as probable-duplicates and (erroneously) not respond at all. * Aug 4 2008 (Yang Tse) - Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use. Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62 version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols no matter if the system is AIX or not. To keep the traditional behaviour, and an uniform one across autoconf versions AC_AIX is replaced with our own internal macro CARES_CHECK_AIX_ALL_SOURCE. * Aug 1 2008 (Yang Tse) - Configure process now checks if the preprocessor _REENTRANT symbol is already defined. If it isn't currently defined a set of checks are performed to test if its definition is required to make visible to the compiler a set of *_r functions. Finally, if _REENTRANT is already defined or needed it takes care of making adjustments necessary to ensure that it is defined equally for the configure process tests and generated config file. * Jul 20 2008 (Yang Tse) - When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID, RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID. * Jul 17 2008 (Yang Tse) - RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined to the data type pointed by its respective argument and not the pointer type. * Jul 16 2008 (Yang Tse) - Improved configure detection of number of arguments for getservbyport_r. Detection is now based on compilation checks instead of linker ones. - Configure process now checks availability of recvfrom() socket function and finds out its return type and the types of its arguments. Added definitions for non-configure systems config files, and introduced macro sreadfrom which will be used on udp sockets as a recvfrom() wrapper in the future. * Jul 15 2008 (Yang Tse) - Introduce definition of _REENTRANT symbol in setup.h to improve library usability. Previously the configure process only used the AC_SYS_LARGEFILE macro for debug builds, now it is also used for non-debug ones enabling the use of configure options --enable-largefile and --disable-largefile which might be needed for library compatibility. Remove checking the size of curl_off_t, it is no longer needed. * Jul 3 2008 (Daniel Stenberg) - Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and the target host has only A records, it automatically falls back to an AF_INET lookup and gives you the A results. However, if the target host has a CNAME record, this behaviour is defeated since the original query does return some data even though ares_parse_aaa_reply() doesn't consider it relevant. Here's a small patch to make it behave the same with and without the CNAME. * Jul 2 2008 (Yang Tse) - Fallback to gettimeofday when monotonic clock is unavailable at run-time. * Jun 30 2008 (Daniel Stenberg) - As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is not posix or anything and thus c-ares failed to build on hurd (and possibly elsewhere). The define was also somewhat artificially used in the windows port. Now, I instead rewrote the use of gethostbyname to enlarge the host name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN define. I thus also removed the defien from the namser.h file where it was once added for the windows build. I also fixed init_by_defaults() function to not leak memory in case if error. * Jun 9 2008 (Yang Tse) - Make libcares.pc generated file for pkg-config include information relative to the libraries needed for the static linking of c-ares. * May 30 2008 (Yang Tse) - Brad House fixed a missing header file inclusion in adig sample program. Version 1.5.2 (May 29, 2008) * May 13 2008 (Daniel Stenberg) - Introducing millisecond resolution support for the timeout option. See ares_init_options()'s ARES_OPT_TIMEOUTMS. * May 9 2008 (Yang Tse) - Use monotonic time source if available, for private function ares__tvnow() * May 7 2008 (Daniel Stenberg) - Sebastian made c-ares able to return all PTR-records when doing reverse lookups. It is not common practice to have multiple PTR-Records for a single IP, but its perfectly legal and some sites have those. - Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to autoconf 2.57 usage (which is the version you have specified as the minimum version). It's a minor change but it does clean up some warnings with newer autoconf (specifically 2.62). * May 5 2008 (Yang Tse) - Improved parsing of resolver configuration files. * April 4 2008 (Daniel Stenberg) - Eino Tuominen improved the code when a file is used to seed the randomizer. - Alexey Simak made adig support NAPTR records - Alexey Simak fixed the VC dsp file by adding the missing source file ares_expand_string.c * December 11 2007 (Gisle Vanem) - Added another sample application; acountry.c which converts an IPv4-address(es) and/or host-name(s) to country-name and country-code. This uses the service of the DNSBL at countries.nerd.dk. * December 3 2007 (Daniel Stenberg) - Brad Spencer fixed the configure script to assume that there's no /dev/urandom when built cross-compiled as then the script cannot check for it. - Erik Kline cleaned up ares_gethostbyaddr.c:next_lookup() somewhat Version 1.5.1 (Nov 21, 2007) * November 21 2007 (Daniel Stenberg) - Robin Cornelius pointed out that ares_llist.h was missing in the release archive for 1.5.0 Version 1.5.0 (Nov 21, 2007) * October 2 2007 (Daniel Stenberg) - ares_strerror() segfaulted if the input error number was out of the currently supported range. - Yang Tse: Avoid a segfault when generating a DNS "Transaction ID" in internal function init_id_key() under low memory conditions. * September 28 2007 (Daniel Stenberg) - Bumped version to 1.5.0 for next release and soname bumped to 2 due to ABI and API changes in the progress callback (and possibly more coming up from Steinar) * September 28 2007 (Steinar H. Gunderson) - Don't skip a server if it's the only one. (Bugfix from the Google tree.) - Made the query callbacks receive the number of timeouts that happened during the execution of a query, and updated documentation accordingly. (Patch from the Google tree.) - Support a few more socket options: ARES_OPT_SOCK_SNDBUF and ARES_OPT_SOCK_RCVBUF - Always register for TCP events even if there are no outstanding queries, as the other side could always close the connection, which is a valid event which should be responded to. * September 22 2007 (Daniel Stenberg) - Steinar H. Gunderson fixed: Correctly clear sockets from the fd_set on in several functions (write_tcp_data, read_tcp_data, read_udp_packets) so that if it fails and the socket is closed the following code doesn't try to use the file descriptor. - Steinar H. Gunderson modified c-ares to now also do to DNS retries even when TCP is used since there are several edge cases where it still makes sense. - Brad House provided a fix for ares_save_options(): Apparently I overlooked something with the ares_save_options() where it would try to do a malloc(0) when no options of that type needed to be saved. On most platforms, this was fine because malloc(0) doesn't actually return NULL, but on AIX it does, so ares_save_options would return ARES_ENOMEM. * July 14 2007 (Daniel Stenberg) - Vlad Dinulescu fixed two outstanding valgrind reports: 1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short int variable) with qid, which is declared as an int variable. Moreover, DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID sets only the first two bytes of qid. I think that qid should be declared as "unsigned short" in this function. 2. The same problem occurs in ares_process.c, process_answer() . query->qid (an unsigned short integer variable) is compared with id, which is an integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets only the first two bytes of id. I think that the id variable should be declared as "unsigned short" in this function. Even after declaring these variables as "unsigned short", the valgrind errors are still there. Which brings us to the third problem. 3. The third problem is that Valgrind assumes that query->qid is not initialised correctly. And it does that because query->qid is set from DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And qbuf has uninitialised bytes because of channel->next_id . And next_id is set by ares_init.c:ares__generate_new_id() . I found that putting short r=0 in this function (instead of short r) makes all Valgrind warnings go away. I have studied ares__rc4() too, and this is the offending line: buffer_ptr[counter] ^= state[xorIndex]; (ares_query.c:62) This is what triggers Valgrind.. buffer_ptr is unitialised in this function, and by applying ^= on it, it remains unitialised. Version 1.4.0 (June 8, 2007) * June 4 2007 (Daniel Stenberg) - James Bursa reported a major memory problem when resolving multi-IP names and I found and fixed the problem. It was added by Ashish Sharma's patch two days ago. When I then tried to verify multiple entries in /etc/hosts after my fix, I got another segfault and decided this code was not ripe for inclusion and I reverted the patch. * June 2 2007 - Brad Spencer found and fixed three flaws in the code, found with the new gcc 4.2.0 warning: -Waddress - Brad House fixed VS2005 compiler warnings due to time_t being 64bit. He also made recent Microsoft compilers use _strdup() instead of strdup(). - Brad House's man pages for ares_save_options() and ares_destroy_options() were added. - Ashish Sharma provided a patch for supporting multiple entries in the /etc/hosts file. Patch edited for coding style and functionality by me (Daniel). * May 30 2007 - Shmulik Regev brought cryptographically secure transaction IDs: The c-ares library implementation uses a DNS "Transaction ID" field that is seeded with a pseudo random number (based on gettimeofday) which is incremented (++) between consecutive calls and is therefore rather predictable. In general, predictability of DNS Transaction ID is a well known security problem (e.g. http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based implementation vulnerable to DNS poisoning. Credit goes to Amit Klein (Trusteer) for identifying this problem. The patch I wrote changes the implementation to use a more secure way of generating unique IDs. It starts by obtaining a key with reasonable entropy which is used with an RC4 stream to generate the cryptographically secure transaction IDs. Note that the key generation code (in ares_init:randomize_key) has two versions, the Windows specific one uses a cryptographically safe function provided (but undocumented :) by the operating system (described at http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx). The default implementation is a bit naive and uses the standard 'rand' function. Surely a better way to generate random keys exists for other platforms. The patch can be tested by using the adig utility and using the '-s' option. - Brad House added ares_save_options() and ares_destroy_options() that can be used to keep options for later re-usal when ares_init_options() is used. Problem: Calling ares_init() for each lookup can be unnecessarily resource intensive. On windows, it must LoadLibrary() or search the registry on each call to ares_init(). On unix, it must read and parse multiple files to obtain the necessary configuration information. In a single-threaded environment, it would make sense to only ares_init() once, but in a heavily multi-threaded environment, it is undesirable to ares_init() and ares_destroy() for each thread created and track that. Solution: Create ares_save_options() and ares_destroy_options() functions to retrieve and free options obtained from an initialized channel. The options populated can be used to pass back into ares_init_options(), it should populate all needed fields and not retrieve any information from the system. Probably wise to destroy the cache every minute or so to prevent the data from becoming stale. - Daniel S added ares_process_fd() to allow applications to ask for processing on specific sockets and thus avoiding select() and associated functions/macros. This function will be used by upcoming libcurl releases for this very reason. It also made me export the ares_socket_t type in the public ares.h header file, since ares_process_fd() uses that type for two of the arguments. * May 25 2007 - Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows that could cause it to return a bad return code. * April 16 2007 - Yang Tse: Provide ares_getopt() command-line parser function as a source code helper function, not belonging to the actual c-ares library. * February 19 2007 - Vlad Dinulescu added ares_parse_ns_reply(). * February 13 2007 - Yang Tse: Fix failure to get the search sequence of /etc/hosts and DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when /etc/resolv.conf did not exist or was unable to read it. * November 22 2006 - Install ares_dns.h too - Michael Wallner fixed this problem: When I set domains in the options struct, and there are domain/search entries in /etc/resolv.conf, the domains of the options struct will be overridden. * November 6 2006 - Yang Tse removed a couple of potential zero size memory allocations. - Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel) broke in the 1.3.2 release. We should switch to a system where that file is auto-generated. We could rip some code for that from curl... Version 1.3.2 (November 3, 2006) * October 12 2006 - Prevent ares_getsock() to overflow if more than 16 sockets are used. * September 11 2006 - Guilherme Balena Versiani: I noted a strange BUG in Win32 port (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network by hand or disconnect the network cable in Windows 2000 or Windows XP, my application gets 127.0.0.1 as the only name server. The problem comes from 'GetNetworkParams' function, that returns the empty string "" as the only name server in that case. Moreover, the Windows implementation of inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE. * August 29 2006 - Brad Spencer did o made ares_version.h use extern "C" for c++ compilers o fixed compiler warnings in ares_getnameinfo.c o fixed a buffer position init for TCP reads * August 3 2006 - Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and not always zero! Version 1.3.1 (June 24, 2006) * July 23, 2006 - Gisle Vanem added getopt() to the ahost program. Currently accepts only [-t {a|aaaa}] to specify address family in ares_gethostbyname(). * June 19, 2006 - (wahern) Removed "big endian" DNS section and RR data integer parser macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise operations in C operate on logical values. And in any event the octets are already in big-endian (aka network) byte order so they're being reversed (thus the source of the breakage). * June 18, 2006 - William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls from area_process.c. TODO: Handle one last EAGAIN for a UDP socket send(2) in ares__send_query(). * May 10, 2006 - Bram Matthys brought my attention to a libtool peculiarity where detecting things such as C++ compiler actually is a bad thing and since we don't need that detection I added a work-around, much inspired by a previous patch by Paolo Bonzini. This also shortens the configure script quite a lot. * May 3, 2006 - Nick Mathewson added the ARES_OPT_SOCK_STATE_CB option that when set makes c-ares call a callback on socket state changes. A better way than the ares_getsock() to get full control over the socket state. * January 9, 2006 - Alexander Lazic improved the getservbyport_r() configure check. * January 6, 2006 - Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS variable for easier controlling what it does and how it runs. * January 5, 2006 - James Bursa fixed c-ares to find the hosts file on RISC OS, and made it build with newer gcc versions that no longer defines "riscos". * December 22 - Daniel Stenberg added ares_getsock() that extracts the set of sockets to wait for action on. Similar to ares_fds() but not restricted to using select() for the waiting. * November 25 - Yang Tse fixed some send() / recv() compiler warnings * September 18 - Added constants that will be used by ares_getaddrinfo - Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it is available to ensure it works properly in a threaded environment. * September 10 - configure fix for detecting a member in the sockaddr_in6 struct which failed on ipv6-enabled HP-UX 11.00 Version 1.3.0 (August 29, 2005) * August 21 - Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info() when getting the DNS server etc. * June 19 - Added some checks for the addrinfo structure. * June 2 - William Ahern: Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a read event can come back from poll() on a valid SOCK_DGRAM socket but recv(2) will still block. This patch doesn't ignore EAGAIN in read_udp_packets(), though maybe it should. (This patch was edited by Daniel Stenberg and a new configure test was added (imported from curl's configure) to properly detect what non-blocking socket approach to use.) I'm not quite sure how this was happening, but I've been seeing PTR queries which seem to return empty responses. At least, they were empty when calling ares_expand_name() on the record. Here's a patch which guarantees to NUL-terminate the expanded name. The old behavior failed to NUL-terminate if len was 0, and this was causing strlen() to run past the end of the buffer after calling ares_expand_name() and getting ARES_SUCCESS as the return value. If q is not greater than *s then it's equal and *s is always allocated with at least one byte. * May 16 - Added ares_getnameinfo which mimics the getnameinfo API (another feature that could use testing). * May 14 - Added an inet_ntop function from BIND for systems that do not have it. * April 9 - Made sortlist support IPv6 (this can probably use some testing). - Made sortlist support CIDR matching for IPv4. * April 8 - Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist does not work with IPv6. Also provided an implementation of bitncmp from BIND for systems that do not supply this function. This will be used to add IPv6 support to sortlist. - Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family. The function can lookup IPv6 addresses both from files (/etc/hosts) and DNS lookups. * April 7 - Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac OS X. * April 5 - Dominick Meglio: Provided implementations of inet_net_pton and inet_pton from BIND for systems that do not include these functions. * March 11, 2005 - Dominick Meglio added ares_parse_aaaa_reply.c and did various adjustments. The first little steps towards IPv6 support! * November 7 - Fixed the VC project and makefile to use ares_cancel and ares_version * October 24 - The released ares_version.h from 1.2.1 says 1.2.0 due to a maketgz flaw. This is now fixed. Version 1.2.1 (October 20, 2004) * September 29 - Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for other OSes. He made c-ares check for and understand it if present. - Now c-ares will use local host name lookup _before_ DNS resolving by default if nothing else is told. * September 26 - Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf file to determine the sequence in which to search /etc/hosts and DNS. So on systems where this order is defined by /etc/host.conf instead of a "lookup" entry in /etc/resolv.conf, c-ares will always default to looking in DNS first, and /etc/hosts second. c-ares now looks at 1) resolv.conf (for the "lookup" line); 2) nsswitch.fon (for the "hosts:" line); 3) host.conf (for the "order" line). First match wins. - Dominick Meglio patched: C-ares on Windows assumed that the HOSTS file is located in a static location. It assumed C:\Windows\System32\Drivers\Etc. This is a poor assumption to make. In fact, the location of the HOSTS file can be changed via a registry setting. There is a key called DatabasePath which specifies the path to the HOSTS file: http://www.microsoft.com/technet/itsolutions/network/deploy/depovg/tcpip2k.mspx The patch will make c-ares correctly consult the registry for the location of this file. * August 29 - Gisle Vanem fixed the MSVC build files. * August 20 - Gisle Vanem made c-ares build and work with his Watt-32 TCP/IP stack. * August 13 - Harshal Pradhan made a minor syntax change in ares_init.c to make it build fine with MSVC 7.1 * July 24 - Made the lib get built static only if --enable-debug is used. - Gisle Vanem fixed: Basically in loops like handle_errors(), 'query->next' was assigned a local variable and then query was referenced after the memory was freed by next_server(). I've changed that so next_server() and end_query() returns the next query. So callers should use this ret-value. The next problem was that 'server->tcp_buffer_pos' had a random value at entry to 1st recv() (luckily causing Winsock to return ENOBUFS). I've also added a ares_writev() for Windows to streamline the code a bit more. * July 20 - Fixed a few variable return types for some system calls. Made configure check for ssize_t to make it possible to use that when receiving the send() error code. This is necessary to prevent compiler warnings on some systems. - Made configure create config.h, and all source files now include setup.h that might include the proper config.h (or a handicrafted alternative). - Switched to 'ares_socket_t' type for sockets in ares, since Windows don't use 'int' for that. - automake-ified and libool-ified c-ares. Now it builds libcares as a shared lib on most platforms if wanted. (This bloated the size of the release archive with another 200K!) - Makefile.am now uses Makefile.inc for the c sources, h headers and man pages, to make it easier for other makefiles to use the exact same set of files. - Adjusted 'maketgz' to use the new automake magic when building distribution archives. - Anyone desires HTML and/or PDF versions of the man pages in the release archives? * July 3 - Günter Knauf made c-ares build and run on Novell Netware. * July 1 - Gisle Vanem provided Makefile.dj to build with djgpp, added a few more djgpp fixes and made ares not use 'errno' to provide further info on Windows. * June 30 - Gisle Vanem made it build with djgpp and run fine with the Watt-32 stack. * June 10 - Gisle Vanem's init patch for Windows: The init_by_resolv_conf() function fetches the DNS-server(s) from a series of registry branches. This can be wrong in the case where DHCP has assigned nameservers, but the user has overridden these servers with other prefered settings. Then it's wrong to use the DHCPNAMESERVER setting in registry. In the case of no global DHCP-assigned or fixed servers, but DNS server(s) per adapter, one has to query the adapter branches. But how can c-ares know which adapter is valid for use? AFAICS it can't. There could be one adapter that is down (e.g. a VPN adapter). So it's better to leave this to the IP Helper API (iphlapi) available in Win-98/2000 and later. My patch falls-back to the old way if not available. * June 8 - James Bursa fixed an init issue for RISC OS. * May 11 - Nico Stappenbelt reported that when processing domain and search lines in the resolv.conf file, the first entry encountered is processed and used as the search list. According to the manual pages for both Linux, Solaris and Tru64, the last entry of either a domain or a search field is used. This is now adjusted in the code Version 1.2.0 (April 13, 2004) * April 2, 2004 - Updated various man pages to look nicer when converted to HTML on the web site. * April 1, 2004 - Dirk Manske provided a new function that is now named ares_cancel(). It is used to cancel/cleanup a resolve/request made using ares functions on the given ares channel. It does not destroy/kill the ares channel itself. - Dominick Meglio cleaned up the formatting in several man pages. * March 30, 2004 - Dominick Meglio's new ares_expand_string. A helper function when decoding incoming DNS packages. - Daniel Stenberg modified the Makefile.in to use a for loop for the man page installation to improve overview and make it easier to add man pages. Version 1.1.0 (March 11, 2004) * March 9, 2004 - Gisle Vanem improved build on Windows. * February 25, 2004 - Dan Fandrich found a flaw in the Feb 22 fix. - Added better configure --enable-debug logic (taken from the curl configure script). Added acinclude.m4 to the tarball. * February 23, 2004 - Removed ares_free_errmem(), the function, the file and the man page. It was not used and it did nothing. - Fixed a lot of code that wasn't "64bit clean" and thus caused a lot of compiler warnings on picky compilers. * February 22, 2004 - Dominick Meglio made ares init support multiple name servers in the NameServer key on Windows. * February 16, 2004 - Modified ares_private.h to include libcurl's memory debug header if CURLDEBUG is set. This makes all the ares-functions supervised properly by the curl test suite. This also forced me to add inclusion of the ares_private.h header in a few more files that are using some kind of memory-related resources. - Made the makefile only build ahost and adig if 'make demos' is used. * February 10, 2004 - Dirk Manske made ares_version.h installed with 'make install' * February 4, 2004 - ares_free_errmem() is subject for removal, it is simply present for future purposes, and since we removed the extra parameter in strerror() it won't be used by c-ares! - configure --enable-debug now enables picky compiler options if gcc is used - fixed several compiler warnings --enable-debug showed and Joerg Mueller-Tolk reported Version 1.0.0 (February 3, 2004) * February 3, 2004 - now we produce the libcares.a library instead of the previous libares.a since we are no longer compatible * February 2, 2004 - ares_strerror() has one argument less. This is the first official modification of the existing provided ares API. * January 29, 2004 - Dirk Manske fixed how the socket is set non-blocking. * January 4, 2004 - Dominick Meglio made the private gettimeofday() become ares_gettimeofday() instead in order to not pollute the name space and risk colliding with other libraries' versions of this function. * October 24, 2003. Daniel Stenberg Added ares_version(). Version 1.0-pre1 (8 October 2003) - James Bursa made it run on RISC OS - Dominick Meglio made it run fine on NT4 - Duncan Wilcox made it work fine on Mac OS X - Daniel Stenberg adjusted the windows port - liren at vivisimo.com made the initial windows port * Imported the sources from ares 1.1.1 sbnc-1.3.9/third-party/c-ares/ares_fds.pdf0000644000175000017500000001005011622246124015270 00000000000000%PDF-1.4 %Çì¢ 5 0 obj <> stream xœVín£FýÏSŒÔ…UŸO÷ow6¿sÐè—þeMf4@a ñˆ‡W‡ä /-ûêÜùR€·ÔÅnÀá˜0±ìS½µO€,ˆ&”é×Äœ•ªº_&ú½U5úš)”¨*.Óm]”ª T©LÅ5*r´,J”GÊOi¬šèƒt&Ï„zXšã¿_]\Ìý²6å6[û»4³]¢ÐOQéP lUáõÏΟá{«‰ti…¯ní4¯Ñh‘NúÎÖ¤þ¯£Ë;˜>©¦™Rïa[±ª*ý2Ê=îÔ]¡­ÊÍv8Jï­iõ€ÒDåu:ÑyèÓ/ ŽÜœþU%èaÎqJ/œ`_xôÅŠq›°ñÐnö{Vá‹CʱàLö}e&Ÿôí4ËÐCÓŒ´)qÜýP(À °*¨æ9åyšÞÿQžìE+)£‡‚“#}…=—XcÂR z HfÈ "¨4‰Êb[¦Q­°3q%Ã<ðí‹c<¢LóeßâÑ9Ý“R©„„ù-¥BÓ™'þ£T‰)9¨ë™Z….®¹mšXªM„Ä„ÌçQ–~iDÜ®›˜0©Å;O§~gï´,Ž¬…ÛüÎY.ÞÜÿ1;P¡à.׬ƒ©2õ0?xê-ø^ê0€!¹Úô–†®>öeÇã[m03·E^¥i–Öû¶ã ªt\×Æ­‘ ”A‚ëôÖžOÛùúÍ¡\@k¨}~y3] ¶Ëø%aŒwº¢.k(>¹+ó |B¡p¨VÚb¢Ö5v›øÝÖ°NWkUÕ¨*â¿€"p)³o­U ‹Êg©Ç$Ñè}£ÊÜ c^ã›Câé¸ä$ñ\¨“Žû ã¬ËÏš à5kÆq–yoI£…á£`ÀGèûˆ÷½ E0†FÓÇý˜ÒNŸ¦y6¦®ûây胇>V–n-\JOŒlÓV ïcÓ):¿\\?'P§Uìê£$\pzt~g.¨GõP}UéVÝš ›mÇ&}uÛ¯+ä“›/”Å0 è ¾ó›¾.oíÀß]ÏŸÜ„}îñÃMåm©×>*°ä]½ëÊáým—TE~†>ÌB4ËaloG[ì«ZmªÆÒ€Õn {„_[j Äçö¾±ÕJ˜\F~¢ªŠâõäF7Ë«:­wµÒê ŸØ*^çEV¬öŽ'´ÒDk5Ôg˜zàš³MIàïwÙÞ„7µ¹ºªNT?š†Ö¯ðùf¿Iendstream endobj 6 0 obj 1340 endobj 4 0 obj <> /Contents 5 0 R >> endobj 3 0 obj << /Type /Pages /Kids [ 4 0 R ] /Count 1 >> endobj 1 0 obj <> endobj 7 0 obj <>endobj 11 0 obj <> endobj 12 0 obj <> endobj 8 0 obj <> endobj 13 0 obj <> endobj 10 0 obj <> endobj 9 0 obj <> endobj 14 0 obj <>stream 2011-08-15T18:41:56+02:00 2011-08-15T18:41:56+02:00 groff version 1.20.1 Untitled endstream endobj 2 0 obj <>endobj xref 0 15 0000000000 65535 f 0000001664 00000 n 0000003529 00000 n 0000001605 00000 n 0000001445 00000 n 0000000015 00000 n 0000001425 00000 n 0000001729 00000 n 0000001850 00000 n 0000002066 00000 n 0000001998 00000 n 0000001770 00000 n 0000001800 00000 n 0000001932 00000 n 0000002131 00000 n trailer << /Size 15 /Root 1 0 R /Info 2 0 R /ID [<2AE2EF5BC9F6D2AFF8FA6A0A1758D971><2AE2EF5BC9F6D2AFF8FA6A0A1758D971>] >> startxref 3683 %%EOF sbnc-1.3.9/third-party/c-ares/ares_fds.30000644000175000017500000000352111440771457014700 00000000000000.\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" .\" Permission to use, copy, modify, and distribute this .\" software and its documentation for any purpose and without .\" fee is hereby granted, provided that the above copyright .\" notice appear in all copies and that both that copyright .\" notice and this permission notice appear in supporting .\" documentation, and that the name of M.I.T. not be used in .\" advertising or publicity pertaining to distribution of the .\" software without specific, written prior permission. .\" M.I.T. makes no representations about the suitability of .\" this software for any purpose.

File descriptors will be set in the file descriptor sets pointed to by .I read_fds and .I write_fds as appropriate. File descriptors already set in .I read_fds and .I write_fds will remain set; initialization of the file descriptor sets (using .BR FD_ZERO ) is the responsibility of the caller. .SH RETURN VALUES .B ares_fds returns one greater than the number of the highest socket set in either .I read_fds or .IR write_fds . If no queries are active, .B ares_fds will return 0. .SH SEE ALSO .BR ares_timeout (3), .BR ares_process (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/setup_once.h0000644000175000017500000003304511440771457015347 00000000000000#ifndef __SETUP_ONCE_H #define __SETUP_ONCE_H /* Copyright (C) 2004 - 2010 by Daniel Stenberg et al * * Permission to use, copy, modify, and distribute this software and its * documentation for any purpose and without fee is hereby granted, provided * that the above copyright notice appear in all copies and that both that * copyright notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in advertising or * publicity pertaining to distribution of the software without specific, * written prior permission.

The parameters .I qbuf and .I qlen give the DNS query, which should already have been formatted according to the DNS protocol. When the query is complete or has failed, the ares library will invoke .IR callback . Completion or failure of the query may happen immediately, or may happen during a later call to .BR ares_process (3) or .BR ares_destroy (3). .PP The callback argument .I arg is copied from the .B ares_send argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The query completed. .TP 19 .B ARES_EBADQUERY The query buffer was poorly formed (was not long enough for a DNS header or was too long for TCP transmission). .TP 19 .B ARES_ETIMEOUT No name servers responded within the timeout period. .TP 19 .B ARES_ECONNREFUSED No name servers could be contacted. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP If the query completed, the callback argument .I abuf points to a result buffer of length .IR alen . If the query did not complete, .I abuf will be NULL and .I alen will be 0. .PP Unless the flag .B ARES_FLAG_NOCHECKRESP was set at channel initialization time, .B ares_send will normally ignore responses whose questions do not match the questions in .IR qbuf , as well as responses with reply codes of .BR SERVFAIL , .BR NOTIMP , and .BR REFUSED . Unlike other query functions in the ares library, however, .B ares_send does not inspect the header of the reply packet to determine the error status, so a callback status of .B ARES_SUCCESS does not reflect as much about the response as for other query functions. .SH SEE ALSO .BR ares_process (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/TODO0000644000175000017500000000132711440771457013520 00000000000000TODO ==== ares_reinit() -

The file descriptor sets pointed to by \fIread_fds\fP and \fIwrite_fds\fP should have file descriptors set in them according to whether the file descriptors specified by \fIares_fds(3)\fP are ready for reading and writing. (The easiest way to determine this information is to invoke .B select with a timeout no greater than the timeout given by \fIares_timeout(3)\fP ). .PP The .B ares_process function will invoke callbacks for pending queries if they complete successfully or fail. \fBares_process_fd(3)\fP works the same way but acts and operates only on the specific file descriptors (sockets) you pass in to the function. Use ARES_SOCKET_BAD for "no action". This function is of course provided to allow users of c-ares to void select() in their applications and within c-ares. .SS EXAMPLE The following code fragment waits for all pending queries on a channel to complete: .PP .RS .nf int nfds, count; fd_set readers, writers; struct timeval tv, *tvp; while (1) { FD_ZERO(&readers); FD_ZERO(&writers); nfds = ares_fds(channel, &readers, &writers); if (nfds == 0) break; tvp = ares_timeout(channel, NULL, &tv); count = select(nfds, &readers, &writers, NULL, tvp); ares_process(channel, &readers, &writers); } .fi .RE .SH SEE ALSO .BR ares_fds (3), .BR ares_timeout (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/inet_net_pton.c0000644000175000017500000002550611440771457016046 00000000000000 /* * Copyright (c) 2004 by Internet Systems Consortium, Inc.

Initializations done by this function remain effective until a call to \fIares_library_cleanup(3)\fP is performed. .PP Successive calls to this function do nothing, only the first call done when c-ares is in an uninitialized state is actually effective. .PP The .I flags parameter is a bit pattern that tells c-ares exactly which features should be initialized, as described below. Set the desired bits by ORing the values together. In normal operation you should specify \fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are familiar with it and trying to control some internal c-ares feature. .PP .B This function is not thread safe. You have to call it once the program has started, but this call must be done before the program starts any other thread. This is required to avoid potential race conditions in library initialization, and also due to the fact that \fIares_library_init(3)\fP might call functions from other libraries that are thread unsafe, and could conflict with any other thread that is already using these other libraries. .PP Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the DllMain function. Doing so will produce deadlocks and other problems. .SH FLAGS .TP 5 .B ARES_LIB_INIT_ALL Initialize everything possible. This sets all known bits. .TP .B ARES_LIB_INIT_WIN32 Initialize Win32/64 specific libraries. .TP .B ARES_LIB_INIT_NONE Initialize nothing extra. This sets no bit. .SH RETURN VALUE Upon successful completion, ares_library_init() will return 0. Otherwise, a non-zero error number will be returned to indicate the error. Except for \fIares_strerror(3)\fP, you shall not call any other c-ares function upon \fIares_library_init(3)\fP failure. .SH AVAILABILITY This function was first introduced in c-ares version 1.7.0 along with the definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an indication of the availability of this function. .PP Since the introduction of this function it is absolutely mandatory to call it for any Win32/64 program using c-ares. .PP Non-Win32/64 systems can still use c-ares version 1.7.0 without calling \fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly a do-nothing function on non-Win32/64 platforms at this point. .SH SEE ALSO .BR ares_library_cleanup(3), .BR ares_strerror(3) .SH AUTHOR Yang Tse .PP Copyright 1998 by the Massachusetts Institute of Technology. .br Copyright (C) 2004-2009 by Daniel Stenberg. sbnc-1.3.9/third-party/c-ares/ares_destroy.30000644000175000017500000000270111440771457015614 00000000000000.\" .\" Copyright 1998 by the Massachusetts Institute of Technology. .\" .\" Permission to use, copy, modify, and distribute this .\" software and its documentation for any purpose and without .\" fee is hereby granted, provided that the above copyright .\" notice appear in all copies and that both that copyright .\" notice and this permission notice appear in supporting .\" documentation, and that the name of M.I.T. not be used in .\" advertising or publicity pertaining to distribution of the .\" software without specific, written prior permission. .\" M.I.T. makes no representations about the suitability of .\" this software for any purpose.

So, # passing -version-info 3:12:1 sets current to 3, revision to 12, and age to # 1. # # If either revision or age are omitted, they default to 0. Also note that age # must be less than or equal to the current interface number. # # Here are a set of rules to help you update your library version information: # # 1.Start with version information of 0:0:0 for each libtool library. # # 2.Update the version information only immediately before a public release of # your software. More frequent updates are unnecessary, and only guarantee # that the current interface number gets larger faster. # # 3.If the library source code has changed at all since the last update, then # increment revision (c:r+1:a) # # 4.If any interfaces have been added, removed, or changed since the last # update, increment current, and set revision to 0. (c+1:r=0:a) # # 5.If any interfaces have been added since the last public release, then # increment age. (c:r:a+1) # # 6.If any interfaces have been removed since the last public release, then # set age to 0.

The parameter .I name gives the query name as a NUL-terminated C string of period-separated labels optionally ending with a period; periods and backslashes within a label must be escaped with a backslash. The parameters .I dnsclass and .I type give the class and type of the query using the values defined in .BR . When the query is complete or has failed, the ares library will invoke .IR callback . Completion or failure of the query may happen immediately, or may happen during a later call to .BR ares_process (3) or .BR ares_destroy (3). .PP The callback argument .I arg is copied from the .B ares_query argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The query completed successfully. .TP 19 .B ARES_ENODATA The query completed but contains no answers. .TP 19 .B ARES_EFORMERR The query completed but the server claims that the query was malformatted. .TP 19 .B ARES_ESERVFAIL The query completed but the server claims to have experienced a failure. (This code can only occur if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_ENOTFOUND The query completed but the queried-for domain name was not found. .TP 19 .B ARES_ENOTIMP The query completed but the server does not implement the operation requested by the query. (This code can only occur if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_EREFUSED The query completed but the server refused the query. (This code can only occur if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_EBADNAME The query name .I name could not be encoded as a domain name, either because it contained a zero-length label or because it contained a label of more than 63 characters. .TP 19 .B ARES_ETIMEOUT No name servers responded within the timeout period. .TP 19 .B ARES_ECONNREFUSED No name servers could be contacted. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP If the query completed (even if there was something wrong with it, as indicated by some of the above error codes), the callback argument .I abuf points to a result buffer of length .IR alen . If the query did not complete, .I abuf will be NULL and .I alen will be 0. .SH SEE ALSO .BR ares_process (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_version.pdf0000644000175000017500000000720711622246253016216 00000000000000%PDF-1.4 %Çì¢ 5 0 obj <> stream xœmUéŽÛ6þ¯§ ?B/b–—D( l#Ý`ãMl¥@alÓ¶RKrtd³ÕwìP¢|Ä…áÎð;fÆ_Q̽ü÷:~žiØÕƒ·øÞ_ÞÿµÎá·ÅîA² ú<Z€V ’<FQüñûÙdþùÏÉlþð4]¹ÁÍ“Qò%3*¸de –¥&t•eÉc@¦÷£Wˆ£<¤¡‘x[² Èû‰K=ãŒ*¦aÌ… 3wÿ‚¤•­?ñتÎÊþ…·¶foÁ=¥Œ«hm¾²”Û.|ÈVUZ½ŒþNÞ]£#¬1hÜ¡˜ÿ5}ú0˜÷XŒÇÒép,ÈOY±>´ ¿¤Õˆkj 7ÄÖtÿkW»¯ô$w ².‹ºõ>­àÎŽ)c:&ƒ‰"Š=Ø%ÉŠî<:Î/„¦:êZok0WC—tÁ¥ÌP)Mìåì¸fÊĶ8“}3™ÿ>{ø w×ÚŸù’do¯µ@"2fåEˆî·¼<Ä¡nQ)˜w›Dô®nÛbÝ8Ëv¶©/Ý‚K«ÓR¨›*+v(.'=^ºP(¡íš€™˜ìÐúº)+»Áç®æÚJÅiÈ/µ¬OwGÇ uâ':6(„ aßاy‰¨áLxÙ_§~x쎪ÐåƒÕλÖ)½ ½mn‹†ÂÃ^ÊŽiíØN?=>¾†¢ôÔ”ÓVwÔ2 7Í lJXY¨lÓV…ÝоTˆt,”»ƒSêþôó¢Z$‡j«.+ o®ËŠ»¹o³CíÑé,Ô*kül96’ê°§ª©â‚:<Ÿ¨rI•Ž‡@Öì!†ÚÓ*m,`±ÚIlË òô ~þOq®Qw ÅósqE™Ôf(^œÒ]‹tVÈHR‡ƒ‘œÝIAŽi³Þ_\†KÎEÖ®K¹Ô`š\2a±>õÌeËÓ\ËÇLiì´Ì¯!͇¶õ[·xꇢR ÏÙáp陋¸¾÷m*âˆFCs:ÄQ‡ø{º±ë,O¨Ç2 i¬Ã«EIØw†=‰“¶$CJ±/Gôv-\.À™>¤b’Læ?ŒïÕZ@ò§¹ÅßE‰›®ÌQÔlu°H}vÛšúyU|ó‡p½zï?…qÇHíHþxšÝü7hôõ¼”ߤEf0olátÖòίdå.«¸¯' ¼K‹ÖíÁ˜ê¦:”ù$Ü=™$ÁG|ý©â)endstream endobj 6 0 obj 931 endobj 4 0 obj <> /Contents 5 0 R >> endobj 3 0 obj << /Type /Pages /Kids [ 4 0 R ] /Count 1 >> endobj 1 0 obj <> endobj 7 0 obj <>endobj 11 0 obj <> endobj 12 0 obj <> endobj 8 0 obj <> endobj 13 0 obj <> endobj 10 0 obj <> endobj 9 0 obj <> endobj 14 0 obj <>stream 2011-08-15T18:43:23+02:00 2011-08-15T18:43:23+02:00 groff version 1.20.1 Untitled endstream endobj 2 0 obj <>endobj xref 0 15 0000000000 65535 f 0000001254 00000 n 0000003112 00000 n 0000001195 00000 n 0000001035 00000 n 0000000015 00000 n 0000001016 00000 n 0000001319 00000 n 0000001440 00000 n 0000001649 00000 n 0000001581 00000 n 0000001360 00000 n 0000001390 00000 n 0000001522 00000 n 0000001714 00000 n trailer << /Size 15 /Root 1 0 R /Info 2 0 R /ID [<8B180197057A36B16BEC93993F483BCD><8B180197057A36B16BEC93993F483BCD>] >> startxref 3266 %%EOF sbnc-1.3.9/third-party/c-ares/ares_llist.h0000644000175000017500000000250711440771457015343 00000000000000#ifndef __ARES_LLIST_H #define __ARES_LLIST_H /* Copyright 1998 by the Massachusetts Institute of Technology. * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

The parameter .I name gives the hostname as a NUL-terminated C string, and .I family gives the desired type of address for the resulting host entry. When the query is complete or has failed, the ares library will invoke \fIcallback\fP. Completion or failure of the query may happen immediately, or may happen during a later call to \fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP. .PP The callback argument .I arg is copied from the .B ares_gethostbyname argument .IR arg . The callback argument .I status indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS The host lookup completed successfully. .TP 19 .B ARES_ENOTIMP The ares library does not know how to find addresses of type .IR family . .TP 19 .B ARES_EBADNAME The hostname .B name is composed entirely of numbers and periods, but is not a valid representation of an Internet address. .TP 19 .B ARES_ENOTFOUND The address .I addr was not found. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP On successful completion of the query, the callback argument .I hostent points to a .B struct hostent containing the name of the host returned by the query. The callback need not and should not attempt to free the memory pointed to by .IR hostent ; the ares library will free it when the callback returns. If the query did not complete successfully, .I hostent will be .BR NULL . .SH SEE ALSO .BR ares_process (3), .BR ares_gethostbyaddr (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/nameser.h0000644000175000017500000001700711440771457014635 00000000000000 #ifndef ARES_NAMESER_H #define ARES_NAMESER_H /* header file provided by liren@vivisimo.com */ #ifndef HAVE_ARPA_NAMESER_H #define NS_PACKETSZ 512 /* maximum packet size */ #define NS_MAXDNAME 256 /* maximum domain name */ #define NS_MAXCDNAME 255 /* maximum compressed domain name */ #define NS_MAXLABEL 63 #define NS_HFIXEDSZ 12 /* #/bytes of fixed data in header */ #define NS_QFIXEDSZ 4 /* #/bytes of fixed data in query */ #define NS_RRFIXEDSZ 10 /* #/bytes of fixed data in r record */ #define NS_INT16SZ 2 #define NS_INADDRSZ 4 #define NS_IN6ADDRSZ 16 #define NS_CMPRSFLGS 0xc0 /* Flag bits indicating name compression. */ #define NS_DEFAULTPORT 53 /* For both TCP and UDP. */ typedef enum __ns_class { ns_c_invalid = 0, /* Cookie. */ ns_c_in = 1, /* Internet. */ ns_c_2 = 2, /* unallocated/unsupported. */ ns_c_chaos = 3, /* MIT Chaos-net. */ ns_c_hs = 4, /* MIT Hesiod. */ /* Query class values which do not appear in resource records */ ns_c_none = 254, /* for prereq. sections in update requests */ ns_c_any = 255, /* Wildcard match. */ ns_c_max = 65536 } ns_class;

The argument .I encoded gives the beginning of the encoded string, and the arguments .I abuf and .I alen give the containing message buffer (necessary for the processing of indirection pointers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the variable pointed to by .IR s . The length of the encoded string is stored in the variable pointed to by .I enclen so that the caller can advance past the encoded string to read further data in the message. .SH RETURN VALUES .B ares_expand_string can return any of the following values: .TP 15 .B ARES_SUCCESS Expansion of the encoded string succeeded. .TP 15 .B ARES_EBADSTR The encoded string was malformed and could not be expanded. .TP 15 .B ARES_ENOMEM Memory was exhausted. .SH SEE ALSO .BR ares_free_string (3) .SH AUTHOR Dominick Meglio sbnc-1.3.9/third-party/c-ares/Makefile.netware0000644000175000017500000003433611440771457016142 00000000000000################################################################# # ## Makefile for building libcares (NetWare version - gnu make) ## Use: make -f Makefile.netware ## ## Comments to: Guenter Knauf http://www.gknw.de/phpbb # ################################################################# # Edit the path below to point to the base of your Novell NDK. ifndef NDKBASE NDKBASE = c:/novell endif ifndef INSTDIR INSTDIR = ../ares-$(LIBCARES_VERSION_STR)-bin-nw endif # Edit the vars below to change NLM target settings.

The parameter .I name gives the alias name or the base of the query name as a NUL-terminated C string of period-separated labels; if it ends with a period, the channel's search domains will not be used. Periods and backslashes within a label must be escaped with a backslash. The parameters .I dnsclass and .I type give the class and type of the query using the values defined in .BR . When the query sequence is complete or has failed, the ares library will invoke .IR callback . Completion or failure of the query sequence may happen immediately, or may happen during a later call to .BR ares_process (3) or .BR ares_destroy (3). .PP The callback argument .I arg is copied from the .B ares_search argument .IR arg . The callback argument .I status indicates whether the query sequence ended with a successful query and, if not, how the query sequence failed. It may have any of the following values: .TP 19 .B ARES_SUCCESS A query completed successfully. .TP 19 .B ARES_ENODATA No query completed successfully; when the query was tried without a search domain appended, a response was returned with no answers. .TP 19 .B ARES_EFORMERR A query completed but the server claimed that the query was malformatted. .TP 19 .B ARES_ESERVFAIL No query completed successfully; when the query was tried without a search domain appended, the server claimed to have experienced a failure. (This code can only occur if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_ENOTFOUND No query completed successfully; when the query was tried without a search domain appended, the server reported that the queried-for domain name was not found. .TP 19 .B ARES_ENOTIMP A query completed but the server does not implement the operation requested by the query. (This code can only occur if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_EREFUSED A query completed but the server refused the query. (This code can only occur returned if the .B ARES_FLAG_NOCHECKRESP flag was specified at channel initialization time; otherwise, such responses are ignored at the .BR ares_send (3) level.) .TP 19 .B ARES_TIMEOUT No name servers responded to a query within the timeout period. .TP 19 .B ARES_ECONNREFUSED No name servers could be contacted. .TP 19 .B ARES_ENOMEM Memory was exhausted. .TP 19 .B ARES_EDESTRUCTION The name service channel .I channel is being destroyed; the query will not be completed. .PP The callback argument .I timeouts reports how many times a query timed out during the execution of the given request. .PP If a query completed successfully, the callback argument .I abuf points to a result buffer of length .IR alen . If the query did not complete successfully, .I abuf will usually be NULL and .I alen will usually be 0, but in some cases an unsuccessful query result may be placed in .IR abuf . .SH SEE ALSO .BR ares_process (3) .SH AUTHOR Greg Hudson, MIT Information Systems .br Copyright 1998 by the Massachusetts Institute of Technology. sbnc-1.3.9/third-party/c-ares/ares_strerror.c0000644000175000017500000000355311440771457016073 00000000000000 /* Copyright 1998 by the Massachusetts Institute of Technology. * * Permission to use, copy, modify, and distribute this * software and its documentation for any purpose and without * fee is hereby granted, provided that the above copyright * notice appear in all copies and that both that copyright * notice and this permission notice appear in supporting * documentation, and that the name of M.I.T. not be used in * advertising or publicity pertaining to distribution of the * software without specific, written prior permission. * M.I.T. makes no representations about the suitability of * this software for any purpose.

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 Lesser 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 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) 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General Public License instead of this License.sbnc-1.3.9/README.iface20000644000175000017500000000116511440771457011417 00000000000000Iface2 Security --------------- Iface2 has a new security feature called "trusted ip addresses". Usually an IP address will be blocked for 10 minutes after 3 bad login attempts (wrong username or wrong password). However, iface2 will not block IP addresses which are in the list of trusted IP addresses. You can view and modify the list using the following iface2 commands: addtrustedip removetrustedip gettrustedips Adding hostnames will NOT work. You can only use IP addresses. For the sake of simplicity IP addresses are compared using string comparison. So adding "127.000.000.001" as a trusted IP address will NOT work. sbnc-1.3.9/README.copyright0000644000175000017500000001322311442467507012274 00000000000000Third Party Software -------------------- autogen.sh: ~~~~~~~~~~~ Copyright (c) 2005-2009 United States Government as represented by the U.S. Army Research Laboratory.
