How to accept on a certain port with linux network code

Question

I am in a situation where I must use a particular port for firewall reasons on one side to make a peer to peer connection. I was wondering if it's possible to open a connection with a client on a particular port. I know about the listen() and accept() functions.

Thanks

You need to use bind ( http://linux.die.net/man/2/bind ).

There are many examples of servers on the web.
