Finding the process that is using a certain port in Linux

How may I find out which process(daemon) is listening on a given port if I do not have a service that would specifically listen on that port? For example if port 10101 is open how can I close the respective process?

You can do netstat -tulpn and grep for the name of the port.

For instance, using your example port, the command would be netstat -tulpn | grep 10101

You can use lsof (list open files) to get the Process ID.

E.g. lsof | grep 10101

Then use can get the process name from /proc (cd /proc/processIDnumber).

Yes. A more specific way would be lsof -i :10101 – Sebi Jan 08 '13 at 18:07
Thank. I was struggling with the man page which is somehow messed up on my system. – Hennes Jan 08 '13 at 18:09
