This will show only processes owned by user. So, unless you're logged in as root, prepend sudo. –  xyz Aug 3 '09 at 12:57

Assuming that you are root.

netstat -lnp

The 4th and 7th fields are what you want.

Alternatively you can get much more detailed information with lsof(1).

This works pretty well for me on linux only:
netstat -anp|egrep -i 'PID/Program|LISTEN'

-a = All sockets -n = doNt resolve IPs -p = show Pids/Programs associated with each
