display processes listening on the ports

[Victor Lin Qiang]

Hello everyone,

Does anyone know a trick to find out which processes are listening on certain ports?

Regular netstat lists many listening ports as
tcp 0 0 localhost. *.* LISTEN
or
tcp 0 0 *. *.* LISTEN
But the processes info is not available.

On Linux, I could use 'netstat -p' (or command lsof). On Windows, I could use 'netstat -a -b'. Is there a way to display the process info on HP-UX? Or is there another command to retrieve similar information? Thank you in advance!

Best regards,
Victor

Hi Victor:

Download 'lsof' :

If you already know about lsof, why not using it?

Have a look at 'lsof'. If you don't have it, download and install it.

Say you want to look for something on TCP port 1234.

# lsof -i tcp:1234
