Who's using my port? (AIX)

Sometimes is very useful know what process is using a specific port. In AIX, the netstat command show you this info using the following parameters:

netstat -Aan

So, you must use grep to filter the port you are looking for.

The first column shows a hexadecimal number. Using the rmsock command with the following parameters to see the PID:

rmsock (hexnumber) tcpcb

or udpcb
