Hi, > Is it possible to tell which proccess is using a tcp port of the box?
Sure, although probably not in the way you had in mind. AFAIK there is currently no tool that lists open connections along with a list of processes that created them. What you can do is use netstat to list active connections, and then look up the well-known ports in /etc/services to get an idea what's going on. I.e. on my box I had the problem that some background task always opened an IP connection which caused a dialout. By this method I saw it was an NNTP connection. The only thing active at that time that was remotely concerned with NNTP was innd. So I stopped innd, and the problem went away. Turned out there was a configuration problem on my side: I changed providers a while back, but inn was configured to use the old machine as local server... Apart from that you can also use strace to find out which ports are opened by a particular program.
