RE: see which programs are opening ports

Even better, with lsof to get the PIDs

lsof -I -n | egrep 'COMMAND|LISTEN'

This will give you the PIDs of all ports that are either in a listen or
command state.

You could use 'lsof' ... and pipe it through 'grep' to get the network
ports

$ lsof | grep 'IPv.'
