Amanda and tape, but hopefully useful with other programs

Amanda's hard core pull -- there's a server on the LAN that does all
the LAN and DMZ backing up. Part of Amanda's configuration is a list
of things around the network to back up. To deal with wandering
laptops, I have a shell script that looks around to find out what's
there and creates a modified version of that list just before Amanda
runs. Anything that doesn't respond to a ping doesn't get backed up.
