[Nolug] network terminology

The "loopback" interface is 127.0.0.1, usually. Even if you don't have any
network cards in your machine, you can still ping yourself, if you use the
loopback interface. This is needed, because many *nix programs are
network-aware and won't function right if there isn't some sort of network
available to it.

Pop open a shell (command prompt) and type "netstat -an " (or perhaps "netstat
-an | grep -i listen") and you'll see that at least some of the services that
are running on your box are listening on the loopback interface.

Hope this helps (although I'm not sure where Ron was going with that... I
haven't been following this thread).
