find process associated with a port

e.g.

fuser 25/tcp (see which pid is listening on smtp)

There are 2 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

lsof -i tcp:25

gives a little more info; *both* fuser and lsof need root privileges to report processes other than the ones they run as, though (whereas

netstat -ap

will at least show you the port is open, though it won't find the pid without privileges...

For some reason fuser doesn't work sometimes, but lsof does. I will look into that later.
