Free bridge software for linux

mbridge provides a multicast DNS services bridge.

mbridge provides a bridge between LANs for multicast-announced services. As an example, you can use it to share iTunes libraries outside of your LAN with your peers.

It works by querying for and listening to announcements for instances of the desired service using the multicast DNS (mDNS) service discovery protocol.

Upon discovery of a new instance, it announces itself as the provider for that service on all the other LANs.

It then acts as a proxy between the clients and the real server.

How It Works

mbridge queries for and listens to announcements for instances of the desired service using the multicast DNS (mDNS) service discovery protocol.

Upon discovery of a new instance, mbridge announces itself as the provider for that service on all the other LANs. It then acts as a proxy between the clients and the real server.

bridged is a user-space alternative to the in-kernel bridge code in Linux. It uses AVL trees to speed lookups. Currently it only offers basic functionality, but if theres interest, I plan to add some more advanced features like access-lists (filtering), SNMP management, telnet console etc.
Bridged doesnt use autoconf/automake yet. If you want to change paths it installs itself to you need to edit Makefile directly. To compile bridged you need flex and GNU avl library (you can download it from http://www.msu.edu/user/pfaffben/avl/) Perfom make and then make install.
By default, bridged looks for its configuration in /etc/bridged.conf, but you can override this by -c argument on command-line. Typical configuration file for making a bridge between two interfaces looks like this:
bridge-group 0
interface eth0
interface eth1
Youll need GNU avl library. For compiling from source RPM, you also need the devel RPM.
Enhancements:
- Aging MAC address table entries implemented.
- Purging MAC address table implemented.
- mac-address-table "aging ", "entries " and "purge-batch " recognized in config file, but no functionality implemented yet.

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.

SIB (Simple IPX Bridge) is able to tunnel IPX and IP frames received by your Ethernet device via UDP over the Internet. It is able to put the interface it listens on to promiscous mode, so all frames (not only broadcasts, and frames for the tunneling server) can be received.
Actually every 802.3 frame can be tunneled, but SIB only tunnels IPX frames per default (this can be changed via command line). SIB also filters SMB over IPX, to reduce network traffic (this can be disabled too).
Additionally SIB takes care which frames belong to local MAC addresses and sends only broadcasts and frame to non-local MACs to the remote host.
A non-plus-ultra is, that SIB can compress every frame it tunnels via LZO, but you must have LZO library installed.
You may ask yourself: "Why should I need this?" Well, there are lot of answers, but the main reason is: FOR GAMES. Even with KALI for Windows ($14.99) and KALI cracked 1.2 ($0 - but bugs bugs bugs) there is no real WHOLE NETWORK to WHOLE NETWORK connection program which can tunnel IPX, filter SMB, compress it, and works with 2.4.0. And EVERY new game (for Windows) uses IPX for "network" (or should I say Internet ;-) games. (RA2, Q3, HL...)
Enhancements:
- fix for "divide by zero" bug on alpha
- fixed hostname resolver
- added option to set local UDP port
- added option to bind to an specific local IP
- MAC lists flushed on SIGHUP

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.

XOscript is a transparent communication bridge between objects running in an application server and the browser. JavaScript programmers have access to the methods supported by server side objects. No additional coding techniques are required to call the method of a server side object. Java programmers are free to build an application using any coding style they choose.

The xoscript framework fully supports Java security. During the invocation of any method the Java programmer may have access to the session metadata as well as cookies, params and attributes passed at method call time. No additional argument signatures are required. The framework supports any method return type including object, primitive or client supported Map and Collection interfaces and may pass an array of the aforementioned.

The JavaScript programmer can take advantage of client side support for all of the Map and Collection interfaces used by Java programmers. Supports for 33 of the most useful classes found in the java.util package have been written in JavaScript.

The goal of this project is to let you code the way you want. Providing a simple framework that stays out of the way yet opens the communication gap between the browser and server. Allowing applications to be written without regard to what the framework can or can not handle. A great deal of thought has gone into the most natural way to achieve this end. Using the default implementation of the framework allows for 90 percent of the code just the way it is written today. Under the covers xoscript is divided into 3 services, invocation, persistence and logging. Each of these services can be implemented through a factory class that understands how to create and use your implementation of the service.

Future goals include bringing a server to client event model into the framework enabling the browser and server to interact as if they were one program and building in support for client side custom tags that can be driven by server side logic. Hope you enjoy XOscript.

Reby stands for: "Ruby-Eggdrop Bridge Yes-this-letter-has-no-meaning-in-the-acronym". Reby allows you to write scripts for eggdrop in Ruby.
Usage
To use Reby with your eggdrop:
1. Move the "reby*" files to some appropriate location such as /path/to/your/eggdrop/scripts/reby . At the least, reby.rb and reby.conf should be together.
2. Enable the .tcl command in your eggdrops conf, if it isnt already. This is usually done by commenting out the following line:
unbind dcc n tcl *dcc:tcl
If you make this change, dont forget to rehash your eggdrop to have the change take effect.
3. Edit the reby.conf file. It is heavily commented and self-explanatory.
4. Run the reby.rb program. You can run it in the background, pipe stdout or stderr wherever you like--whatever you want. By default, it does not run as a daemon, and it writes status and error messages to stdout. It also looks for a configuration file called reby.conf in the same directory. You can pass the path to a specific configuration file as an argument to reby.rb.
And thats it! I hope you enjoy using Reby!
Enhancements:
- Several minor bugs were fixed.
- Many scripts were updated.
