Free bridge card game software for linux

Online Cardgame System project is a client-server system for playing card games over the net.
OCS is a client-server cardgame system, similar to those found at Yahoo! Games and elsewhere. The server is portable and has been tested under Linux, Win32, and several unix systems. We currently have Win32 and Java clients available, and a Qt client for Linux is in development.
Games are implemented as plugin modules, so new games can be added without recompiling the server. In addition, the client is written to be unaware of the mechanics of gameplay, so it can theoretically play any games the server supports without having to know how to play them specifically.
We currently have Euchre and Spades implemented, with bot support for both games, meaning you dont need a full 4 people to play a game. We plan on implementing more games in the future.
On a side note, development of this project tends to wax and wane with our motivation and amount of schoolwork.
Enhancements:
- Massive restructure of code into more object orientated patterns
- Added daemon capability to server
- Got rid of checksumming in the protocol since TCP/IP does it internally
- Padded STRINGS in the protocol on DWORD boundaries
- Added support for loadable account managers
- Removed crypting of the password by ocsd (account managers may do it)
- Added ODBC (for windows) and mySQL (for unix) account managers (database connectivity!!)
- Modified packet classes to throw exceptions instead of returning true-false
- Created packet manager classes to queue client packets, reduces total send calls
- Implemented bots when there arent enough people to play games
- Added new command line processing capabilities as well as configuration file support
- Fixed bug that allowed a person to overwrite an account when creating that same account
- Win32 - Made server link with DLL runtime library to reduce executable size and ease DLL dependencies
- Updated messages to be sent in HTML since the main clients support it
- Created Java client which can be run as an application or as an applet
- After a client is booted from a game, they cannot join the game again until they receive an invitation
- Fixed libtidy bug which caused it to erroneously format HTML
- Euchre supports intelligent bots
- Spades supports moronic bots (the AI is horrible but allows for gameplay)
- Fixed Spades textual problem when a round was over.
- Fixed Spades score calculation that resulted in no loss of points
- Win32 client now supports HTML (IE4+ required)
- Win32 client can now join games by right-clicking on an empty game slot in the game view.
- Fixed major bug in Win32 client that would cause it to crash when sending private messages
- Win32 client can now use /msg to send private messages

PyBridge is a free online bridge game.
PyBridge is software which lets you play the card game of (contract) bridge, with human players, over the Internet or a local network.
Main features:
- Complete bridge game logic: support for bidding, trick playing and duplicate scoring.
- A PyGTK graphical front-end - see the screenshots!
- A standalone server, capable of managing an arbitary number of tables and games.

UDP-Bridge is a transparent proxy for UDP traffic, designed for use with Linux 2.2.x kernels. It provides two-way proxying of UDP packets, to avoid the port number mangling that occurs with Linux IP masquerading. This mangle rule causes problems for some online games.

This program was actually developed to solve a problem with handling Playstation 2 network traffic through a Linux firewall. According to testimonials, most games worked fine with this kind of configuration, but the one that I had tried (ATV Offroad Fury 2) would not work. The problem was apparently the UDP port mangling done by Linux IP masquerading, hence the need for this proxy.

To build the proxy, simply run make from within the source directory:

make

To install the proxy, run the following command as root:

make install

This will install the proxy executable (udpbridge) into /usr/local/sbin, and the man page into /usr/local/man/man8.

The last step is to create and install a configuration file. The included example.conf file is a good template for this. The default location for the configuration file is /etc/udpbridge.conf.

Penguin Cards project is a card game.
PenguinCards is a two-player card game. The aim is to find the pairs of cards on the board. The one who finds out more card pairs is the winner.
PenguinCards is a java-based game.
If you are unhappy with images on the cards, then simply copy your cards into images/pictures/penguins directory. That is it!
Enhancements:
- Initial release

KPicFramer is a small (but slightly maddening) card game for the K Desktop Enviroment.
KPicFramer 0.5 and above require KDE 3.2 including the kdegames module.
Enhancements:
- port to KDE 3.2 (KDE 3.1 might work as well)
- resizable window
- configureable shortcuts, toolbar
- config dialog with more config options
- complete rewrite

The Linux Memory Game project is a childrens (and adults) game based on the card game.
The Linux Memory Game is an X11 game using GTK+ library for children ages 3 and up. It is a lot more than the card game "Memory".
It has five skill levels, the higher ones are challenging to adults as well. Additionally, one can choose from the menu to match 2 cards or 3 cards, or match different cards.
This last "different card" mode can be a very good teaching tool for teaching languages, concepts, or association.
Main features:
- Extensible - add new images yourself without having to make changes to the program.
- Five skill levels appropriate for the youngest and the ones with the best brains.
- Can play two card matching or three card matching (more challenging!)
- Can set to match different cards. This can be used with apropriately designed pictures to teach children (or adults) words, concepts, or another language.
Enhancements:
- Fixed overflow bug in pixmaps_jump.

Linux Bridge Utilities is a bridge is a way to connect two Ethernet segments together in a protocol independent way. Packets are forwarded based on Ethernet address, rather than IP address (like a router). Since forwarding is done at Layer 2, all protocols can go transparently through a bridge.

The Linux bridge code implements a subset of the ANSI/IEEE 802.1d standard. [1]. The original Linux bridging was first done in Linux 2.2, then rewritten by Lennert Buytenhek. The code for bridging has been integrated into 2.4 and 2.6 kernel series.

Manual Configuration

Network cards

Before you start make sure both network cards are set up and working properly. Dont set the IP address, and dont let the startup scripts run DHCP on the ethernet interfaces either. The IP address needs to be set after the bridge has been configured.

The command ifconfig should show both network cards, and they should have be DOWN.

Module loading

In most cases, the bridge code is built as a module. If the module is configured and installed correctly, it will get automatically loaded on the first brctl command.
If your bridge-utilities have been correctly built and your kernel and bridge-module are OK, then issuing a brctl should show a small command synopsis.
