That works great, except for two things:

1) If I'm behind a firewall (which the machine in question is), all 
external machines will see the firewall's IP address.

2) I need a way to determine the IP *without* using the network... in 
other words, without pinging or accessing another machine.

Surely there's something on each Linux box that says what the IP is?

Thanks anyway,
Jeff
