As root, do:
netstat -anp
Parameters as follows:
-a : show me all connections
-n : don't bother looking up DNS records (I don't wanna wait for
DNS to time out multiple times)
-p : show me the process ID that is connected to port in question
Why you need to be root: netstat considers it a security violation to
know about anybody else's [different UID] port / process connections.
I agree with this, although it can be a royal PITA at times.
BTW: netstat vs. lsof:
netstat is more likely to be installed than lsof, and only shows relevant
items when you are wondering about net connections to process IDs.
If you do want to use lsof in this instance, grep Is Your Friend.
However, lsof is a handy util that I recommend that anybody install
and gain familiarity with. As mentioned recently here, lsof +L1 is
a wonderous command -- it shows you open files that have been deleted.
Very useful after you've done an apt-get upgrade. And that's just
one of its myriad of useful applications.
