Information on gaming servers

I want to know whether there is some sort of connect 4 server or something like that,
I think many people here knowFICS its a sort of free chess sever where many people play chess.
Even computer programs are written in such a way that they can play there.

So similar to that I want to know if there is some online server which is connect4 specific.
If there is, then I want to know on further things like how to connect online to that server automatically, start and accept challenges without human interference and other stuff...
