To find out what is running on a port (as opposed to what a port is 
supposed to be for) (example uses port 2064)

As root run
  fuser -n tcp 2064

Which returns
2064/tcp:              222

That means PID 222 is bound to port 2064.

Then do a
  ps auxw | grep 222

Which returns
root       222  0.0  0.8  1608  532 ?        S    Jul20   1:33 
/usr/local/proxy/proxyper
root      1270  0.0  0.6  2220  436 ?        S    Jul30   0:57 
/usr/sbin/nmbd -D
root     22144  0.0  0.6  1112  440 pts/5    S    07:19   0:00 grep 222

^          ^
User      PID

As you can see, /usr/local/proxy/proxyper is PID 222, and therefor is using 
port 2064.
