Hi Berthold,

You can with lsof.

example
# lsof -i tcp:513
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
inetd 982 root 9u inet 0x41e6a068 0t0 TCP *:login (LISTEN)
rlogind 9229 root 0u inet 0x4201e868 0t2665 TCP db001:login->daf68.pg)

Hi,

You can do with "lsof". Download and install from,

After installing, do a "man lsof" for more details.
