Thanks for all the suggestions. lsof is a very interesting command I
didn't know about.

On a hunch, I tried running netcat on the server to open/listen on port
21--and it worked.

When I try this on ports that I know are already open (like 80), netcat
fails (as expected) because the port is alreaady taken--so I'm guessing
that port 21 on the server isn't actually open because netcat works.

Is this a bad assumption? I don't know enough about *nix to judge this
assumption.
