I'd like to know how I can make a Multi user CHAT telnet server ( LINUX ). I know kinda how the commands socket(), accept(), bind(), and listen() work, but how would i be able to get multiple users to be able to connect at one time and send strings from one console to another. a very simple chat server would be VERY much appreciated.

It will get you rolling very fast. There is very little modification that needs to be made, and it is relatively well commented! There is a warning that the code is not fully functional. I compiled it and it ran the first time without modification (he's just protecting himself).

This should help alot, I hope so. If you need more info, let me know!

Once your server listens to a port , accept() returns a socket AND the port is STILL listening . That means that you can accept() as many connections as you want . But you will have to figure how the information and the messages you will receive will be forwarded to all connected users .

well WxW the OS often times limits the number of connections that can be opened. I think on most Lynix implementations it is 400 per socket. But that might be a little off.

Hmmm I am not sure but since Linux has more history as a UNIX platform , it would not allow less sockets to be created than WinSock .... Anyway you may have right
