I have a few computers one acts as a server and the rest are clients. They are all on the same LAN. I need to write a program that when I enter data into one of the clients it sends it back to the server which is constantly listening. The server then sends this data out to all the clients that are constantly listening. What are good ways to do this? Is there a good tutorial that any of you know of that explains this concept well? Thanks a lot.

thanks a lot. that tutorial looks great.
