Free runs on software for linux

Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method.

This projetc comes with a GTK+ Graphical User Interface and runs on ,Linux Mac OS X (Intel CPU) as well as on Windows.

XTux is a multiplayer Gauntlet-style arcade game for X-windows featuring open-source mascots.
XTux runs on Linux, FreeBSD, Solaris, AIX, Irix and other unix-like systems, so players can come together from different platforms to compete in network Holywar deathmatches or work together to take on the evil Microsoft empire. Read the single player story to understand why we must fight!
Enhancements:

Its a free software media manager written in C#, using GTK#. MediaNET runs on both Linux and Windows via the Mono effort ( Portable.Net should work too ), and could handle any type you want, as long as you have the right plugin.

Media types could be wide-known mp3, jpg, and avi, but also virtual types: the best example is the odb file handling ( odb for object database it implements ), which represents a collection.

SDL_sound is a library that handles the decoding of several popular sound file formats, such as .WAV and .MP3. It is meant to make the programmers sound playback tasks simpler. The programmer gives SDL_sound a filename, or feeds it data directly from one of many sources, and then reads the decoded waveform data back at her leisure.
If resource constraints are a concern, SDL_sound can process sound data in programmer-specified blocks. Alternately, SDL_sound can decode a whole sound file and hand back a single pointer to the whole waveform. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly and behind-the-scenes, if the programmer desires.
As the name implies, SDL_sound is an add-on to Simple Directmedia Layer, and as such, youll need it to build and use SDL_sound. SDL gives us lots of convenience for porting and implementing some elements of the library, not to mention that it is a powerful, cross platform answer to DirectX. You should definitely look into it, whether you use SDL_sound or not.
Places SDL_sound is known to be used:
- The Ambient Music System uses SDL_sound in its player module.
- The popular game glTron uses SDL_sound for sound playback.
- Dominik Haumann wrote in to mention C++ wrappers for SDL_sound, which can be found here.
- MusicBox, a GNUstep music manager, uses SDL_sound to decode various audio formats.
- The SuSE Linux distribution has been know to package SDL_sound (at least version 0.1.5 has been spotted in the wild).
- Gentoo Linux distributes SDL_sound via their "portage" system. Just "emerge sdl-sound".
- FreeBSD has SDL_sound in their Ports tree: herere the details.
- NetBSD Appears to have packaged SDL_sound, too: details.
- Debian has packaged SDL_sound, too: details.
- ROCK Linux has an SDL_sound package: details.
- Probably other places. Email me if you want to be listed here.

- Support for decoding through MikMod. (.MOD, .IT, .XM, .S3M, .MTM, .669, .STM, .ULT, .FAR, .MED, .AMF, .DSM, .IMF, .GDM, .STX, .OKT).
- Support for decoding through ModPlug. (.669, .AMF, .AMS, .DBM, .DMF, .DSM, .FAR, .IT, .MDL, .MED, .MOD, .MT2, .MTM, .OKT, .PTM, .PSM, .S3M, .STM, .ULT, .UMX, .XM)
- Experimental support for decoding through Apple Quicktime (MacOS only).
- Compiles/runs on Linux (x86 tested).
- Compiles/runs on Linux (x86-64 tested).
- Compiles/runs on Linux (PowerPC tested).
- Compiles/runs on FreeBSD (x86 tested).
- Compiles/runs on Win32 (x86 tested).
- Compiles/runs on MacOS Classic (PowerPC tested).
- Compiles/runs on MacOS X (PowerPC tested).
- Compiles/runs on BeOS (x86 tested).
- Compiles/runs on WinCE/PocketPC (StrongARM tested).
- May compile and run elsewhere with little to no modification. Success stories and patches are welcome.
What doesnt work:
- Support for more forms of compressed .WAV files is planned, but not yet implemented.
- Support for various forms of compressed .AIFF files is planned, but not yet implemented.
- Contributions of other ports are, of course, welcome.

Shaaft is an OpenGL 3D falling block game similar to Blockout. It currently runs on Linux and Windows.

There is still a lot missing. No menu system, forgets highscore, some of the sound effects need work (Clearing a single plane sounds like a f*rt. Try clearing >1 plane, though...), etc. That said, I find it is very playable. Enjoy!

You control the rotation via q,a,w,s,e,d. Space will drop the block.

C_COUNT counts C-language source statements, and summarizes statistics about
the relative amount of commentary, whitespace, etc.
It provides options to extend its usefulness, accommodating C-preprocessor
definitions that would confuse a simpler line-counter, and for displaying
non-graphic characters, etc.
C_COUNT project runs on a variety of UNIX systems, VMS and MSDOS.
Enhancements:
- correct bookkeeping for unterminated blocks (report by Lester Ingber).

NathanCheckers project is a mouse-driven, graphical implementation of Checkers. American Standard Checkers rules are enforced.
Known Bugs/Issues
- All versions: It appears that sound support currently requires the game to be run from a writable drive (not a disk image or CD).
- Windows: An extra command prompt window stays open. Runs on Windows 2000, but reportedly you need to minimize and maximize it before you can see the gameboard.
- Linux: Requires PyGame 1.6 or above.
- OS X: No quit menu-item (just close the window). How do you add menu items in PyGame anyway?

Prodder is a command-line based Podcast client written in Perl that runs on just about any *n*x system. Prodder implements a few very useful features that are lacking in many of the existing tools, while remaining simple and light-weight.
Main features:
- Interactive and autonomous (cronjob) modes.
- Selective downloading (great for dialupers and low-volume users).
- Extended item information (date, enclosure url/size, description).
- User-defined download directory structure (based on title, category, date).
- Playlist generation.
Prodder is released under the GNU General Pulic Licence.
