Find which process is listening on a port

October 17, 2007 on 6:20 pm | In Unix |

To find which process is listening on port 22:

lsof -i:22

 

Find out which port a process is listening on e.g. httpd:

lsof -P -c httpd -a -i

 

Or by PID:

lsof -P -p 267 -a -i

 

lsof can also be used to find the files a process has open. To look for where httpd writes it’s log files:

lsof -c httpd | grep log
