Unpack the package: tar -zxvf knocker-X.X.X.tar.gz 2. cd knocker-X.X.X 3. type: ./configure 4. make 5. (Become root if you want to install knocker system wide) type: make install -[ You want to start to pollute hosts logfile scanning'em but you don't have a clue ? :) ]- -------------------------------------------------------------- 1. If you have installed knocker with make install you should be able to execute it just by typing: knocker otherwise cd into the src directory under the unpacked source tree and type: ./knocker or better: knocker --help 2. Now to perform a simple port scan to a host (let's use your host as target...) type: knocker --host localhost 3. Let's say you have to perform a long scan and you want the program to run in background so you can continue your work... just type: knocker --host thehost --start-port 1 --end-port 4000 --quiet & or in a shorter form: knocker -H thehost -SP 1 -EP 4000 -q & you won't see any output this way... just do: cat ./knocker_scan.log to see the scan results. Or if you want to log to a particular file: knocker -H thehost -l logfile.txt If you want to scan only one port: knocker -H thehost --port 21 Hope that's enought.... ChEeRs.......

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 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 Library General Public License instead of this License. knocker-0.7.1/ChangeLog0000644000175000001440000002034607473300016010407 -- $Id: ChangeLog file for knocker version 0.7.1 - released on 24 May 2002 ------------------------------------------------------------------------------- 24 May 2002 - Modified knocker_led.c and knocker_led.h to let knocker build on non-linux OS as well. (if linux/kd.h include is found NO_LED will be defined). 19 May 2002 - A --configure option was added. If knocker is executed with this option it will ask a few questions so the user can configure it to its need. It is currently possible to choose if or not to use colors, and actually choose what color to use for a particular output. These settings are stored int the ~/.knocker/knocker.conf file and can be manually changed by the user. - Fixed the wrong results output in the logfile. The total number of scanned ports was reported as the total of the found open ports. 18 May 2002 - Unit knocker_conf was added. The code in this module will handle all the stuffs relative to the kncoker's configuration file. This file (knocker.conf) is automatically created everytime knocker is executed and it can't find its .conf in the user ~/.knocker subdirectory. 13 May 2002 - --no-fency (-nf for short) option added. This switch tells knocker to show the output in a "polite" way. All the lines and stuffs shown in the default mode, will not be displayed using this option. - Function knocker_term_set_color modified no to alter the console background color. This makes knocker to work properly under X11 terminals. It doesn't screw up colors anymore. (Works with transparent background terminals too). 25 April 2002 - Unit knocker_led added. The code in this unit will handle the keyboard leds. The idea is to get the leds blinking while portscanning ... The code is there and it works, but it is not active yet. 7 April 2002 - --last-host option added. This gets the last host name that was scanned. 28 March 2002 - Added the --last-scan option. This option tells knocker to perform again the last port scan. - The unit knocker_user was added. In this module goes all the code that has to do with user relative functions and the knocker user dir.(ex ~/.knocker) 26 March 2002 - Changed the --quiet-mode option in --quiet and the corrispondent short option -qm in -q 9 March 2002 - Fixed a serious bug that was preventing knocker to scan a number of ports greater than 1023, all ports scanned after 1023 ports already scanned were reported as CLOSED ! (Basically I was not closing the socket in the knocker_core_portscan_tcp_connnect (...) function, so that after 1023 open sockets the system was unable to open more of them). - Fixed another bug that was causing knocker to segfault before exiting if a hostname couldn't be resolved. Thanks to Emmanuel Seyman for having reported these bugs. 8 March 2002 - Changed the --enable-logfile option in --logfile. This option now requires a file name to be specified. Ex: knocker -H thehost --logfile log.txt - Added code to manage the list of services (generated from the /etc/services file) in the unit knocker_services to get the correct service name under Win32 platfroms. The getservbyport function in the Winsock lib seems not to work correctly. - Added the --win32-frontend option and the relative code to work with the knocker win32 frontend. 1 March 2002 - Added Win32 Winsock code to work natively on Windows platforms. Knocker can now be builded natively on Win32 platforms. - Added code to handle colored output under Win32 platforms in the unit knocker_term. (using conio.h). - Added a function (knocker_term_reset) to *Fix* the bug that caused knocker not to reset to the console default colors at exit. - Added a function (knocker_term_clear) to clear the screen when knocker is started. - Added a DevC++4 project file to build knocker under Win32s platforms using the IDE/Compiler available at www.bloodshed.net Information on how to build knocker with this IDE can be found in the file README.Win32 - knocker.ico file added in the source distribution. 23 February 2002: - Fixed the segmentation fault that was caused by starting knocker without the --host or -H option. Now the program exits properly and prints an error message to inform the user. - Unit knocker_timer added. This module handles timing stuffs. - The elapsed time is now counted in milliseconds rather than in seconds. - If a wrong option is given as a knocker command line argument, the error message now prints its name. Ex: knocker --hast localhost knocker: invalid argument given: '--hast' 17 February 2002: - Knocker's output style & colors changed. I like it, but you might not, if that's the case, please, let me know. - Elapsed time since the begin of the port scan is now shown in the results. - Module knocker_output added. All the boring fprintf(...) stuffs are now in this unit. This makes the main knocker unit a bit cleaner. - Code to output debug messages was added. 15 February 2002: - Big portions of code rewritten from scratch. - The TCP connect port scan code has been improved. The scan should be faster now. (In the old code the host name was resolved for each port to be scanned!) Damn it. - knocker_core totally redesigned (and rewritten) to be more flexible and versatile. Plans are to make it available as a library/DLL . 13 February 2002: - Fixed a bug in the version 0.5.1 that made impossible to scan a host starting knocker in the default mode Ex: knocker --host thehost This caused knocker to quit without performing the port scan. - Added header file definitions to prevent multiple file inclusion. 09 February 2002: - An option to perform a portscan on a single port was added. The option is --port or -P - threads code removed (since it was quite buggie) Threads support will be redesigned and reimplemented in the future. - Fixed the total scanned ports result counting bug: knocker was not displaying the correct number of the scanned ports. Ex: for a scan from port 1 to port 1000 it was displaying 998 as total resoult insted of 1000. That's now fixed. Thanks to Cristian Ionescu-Idbohrn for reporting that. - Fixed the bug that caused knocker to segfault when the log file couldn't be open. The program now quits gracefully telling the user what's going on. - Compilation is now done with the following flags -Wall -ansi -pedantic - Module terminal.c renamed to knocker_term.c 06 January 2002: - Added the following options: 1. --quiet-mode With this option the program can be started in background so that no output to the console is generated and the scan's results are written to a log file. (knocker_scan.log) Ex: knocker --host 192.168.0.1 --quiet-mode & 2. --enable-logfile This option logs the scan results to a file (knocker_scan.log) Console output is not disabled by this option. 3. --no-threads If you experience problems running knocker with threads just pass this option. Ex: knocker --host 192.168.0.1 --no-threads - Added modules knocker_log.c, knocker_log.h to support the new file logging functions. 27 July 2001: - Added colored output ! - Code to print colored output done. - Added a "--no-colors" option to disabled colored output - Man page updated with new the new option about colors. 26 July 2001: - Begun to add the code to print colored output. 20 July 2001: - Now knocker uses threads (linux pthreads) in the portscan loop. - The port scan process can now be cancelled by pressing the "c" key. - The number of total ports scanned is now correctly shown even if the scan is cancelled. - configure.in modified to use threads. - Three functions added to support the use of threads. 16 July 2001: - Now knocker attempts to resolve an host IP address before the port scan is started. It aborts the scan if the host IP can't be resolved. 15 July 2001: - Added a function in knocker_core.c to resolve hosts IP addresses. 08 July 2001: - Initial release. -- Gabriele Giorgetti knocker-0.7.1/INSTALL0000644000175000001440000001722707321734437007704 Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. knocker-0.7.1/Makefile.am0000644000175000001440000000121607471770741010702 # Makefile.am file for knocker # Edited by Gabriele Giorgetti # This file is processed by automake ## Any directories that are built and installed should go here.

A detailed list of changes can be found in the ChangeLog file. knocker-0.7.1 (24 May 2002): - Fixes a problem in the 0.7.0 version that was causing knocker not to build on non-Linux OS (FreeBSD, OpenBSD, HP-UX, and so on). knocker-0.7.0 (19 May 2002): - A new option to display the program output in a "no-fency" mode was added, and also the possibility to configure knocker with the also new --configure option was added. - The colored output code has been improved and it is not causing the background color to change anymore if knocker is executed in a X11 terminal. The text is now correctly displayed on transparent background terminals too. - Two new options were added, these are --last-scan, to perform again the last port scan, and --last-host, which puts the last scanned host as target. knocker-0.6.6 (9 March 2002): - Fixed a serious bug that was preventing knocker to scan a number of ports greater than 1023. - Fixed another bug that was causing knocker to segfault before exiting if a hostname couldn't be resolved. knocker-0.6.5 (8 March 2002): - knocker is now displaying service names correctly on Win32 platforms. - Added Win32 Winsock code to make knocker work and build natively on Win32 platforms. - Code added to work with a contributed knocker Windows frontend. - Console/terminal colors are now restored to default under Win32 platforms. - Elapsed time is now in milliseconds rather than seconds. - Fixed a bug that caused knocker to segfault if a host was not specified after the --host option. knocker-0.6.0 (17 February 2002): - Changed the knocker's output style & colors. - Big portions of code rewritten from scratch. - TCP connect port scan code has been improved, the port scan should be faster now. - Elapsed time since the port scan started is now shown in the results. knocker-0.5.2 (13 February 2002): - Fixed an important bug that prevented knocker version 0.5.1 to perform the port scan, if started in the default mode. knocker-0.5.1 (11 February 2002): - Added an option to perform a portscan on a single port. - Threads code removed. Knocker is no longer using threads. - Two important bugs fixed. (see ChangeLog for detailed infos). knocker-0.5.0 (06 January 2002): - Added an option to run the program in background and log results to a file. - Options added to log port scan results to a file. - Added an options to disable the use threads. knocker-0.4.0 (27 July 2001): - Added colored output ! - Now knocker is able to print its output using colors. - A option to disable colors ha been added: "--no-colors" knocker-0.3.0 (20 July 2001): - Now knocker uses threads (linux pthreads) in the portscan loop. - The port scan process can now be cancelled by pressing the "c" key. knocker-0.2.0 (16 July 2001): - Now knocker attempts to resolve an host IP address before the port scan is started.
