Sending data between 2 Arduino's over Ethernet

Hi, Im a complete novice when it comes to this but I need to send some data from push switches conntected to an Arduino Uno, to a separate Arduino Uno via Ethernet. I have the boards and the Ethernet shields and have spent ages trying to get them to communicate. Anyone know of any useful tutorials or good websites that may help me out?

Thanks a lot,

Not really a beginners project but if you must you must

If you are familiar with programming of network apps start here - http://arduino.cc/en/Reference/Ethernet
(one must be client, the other a server)

otherwise start here - http://arduino.cc/en/Tutorial/HomePage

Time spend at tutorial site is well spent.

interestiung thread as it has a sample prog - http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1293599816
