Use the `lsof` command to find which process is listening on a given port.

For example, I saw that some process was already using port 69 (normally TFTP). I did not expect this port to be in use, so I ran the following command to find out which process what listening on port 69:

lsof -i :69

So to find which process is listening on port 80 (expect some http server):

lsof -i :80

You can also look for files opened by a given user or command:

lsof -u USER
lsof -c COMMAND
