Free udp bridge 1.0 software for linux

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.

XQuark Bridge project extends relational databases with XQuery and XML-relational mapping.
XQuark Bridge expands existing relational database functionality with advanced XML import/export capabilities.
It supports flexible extraction and publishing of relational data into any target XML format using the XQuery language.
Using a mapping language, it can also perform efficient insertion of structured XML data into existing relational tables, while taking into account the database integrity constraints and transforming the implicit relations appearing in the XML document into explicit ones in the database.
It integrates smoothly with J2EE servers and currently supports MySQL 3.23.X and 4.0.x, Oracle 8i and 9i, MS SQLServer 2000, and Sybase 11.9.2.
Enhancements:
- This is a maintenance release of XQuare Bridge 1.1.
- It features numerous bug fixes capitalized during the past months.
- See the details in the release notes.

aBridge project is a multiplayer online cross-platform bridge game.
It allows you to play bridge online with other real people.
It is currently available for UNIX (including linux), Microsoft Windows and MacOS X.
On all platforms, aBridge supports speech synthesis, allowing you to choose to listen to the bids and chat conversation rather than simply gazing at the screen waiting for someone to play.
aBridge also has some rudimentary bots, for when other players arent online, but their AI is pretty pathetic, and they are in need of a complete rewrite.
Enhancements:
- Complete rewrite of card-displaying code. Cards are now scalable.
- Remember size of game window.
- Use flite instead of festival on sid, since speech-tools is broken on sid at the moment.

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.

PINT is a handy tool for debugging any TCP/IP (or UDP) software. It can be made to listen to a server socket or to connect to a remote host. The resulting connection is displayed, with separate display for the inbound and outbound traffic.
