fuser -n tcp 80 gives u the process id of the program running on port 80
on tcp protocol, here web
same way for udp. fuser -n udp *port*
Hi, I'm really sorry about the newbie question, but there it goes:

I have some programs that makes a conection on it server, and I must

I'm under linux, if anyone knows some tool or something like this I'd be
grateful.

Thanks
