Jim, I'm on a completely switched network, so a lot of the MAC addresses
I have already that I've pulled from the switches never get added to the arp
table in the linux box.  Broadcast pings are out of the question because many
tcp-ip stacks won't reply to a broadcast ping.  If I can't do this sanely in
linux I might be forced to make a port on our core switch mirrored with every
other port on the switch.  Very Ugly!
