If you run a Linux 2.5 kernel there is Amanda support built in to the kernel
(actually its an option in the netfilter section of the kernel config, you
have to enable it).  On older kernels, your best bet is to rebuild your
Amanda server and clients using the 'portrange' options to limit Amanda
to a narrow range of ports and have your firewall rules allow traffic on
those ports between the client and server.
 Another option is to rsync the desired directories on the remote server
to somewhere local that you could then back up.

All the other systems in this set backup just fine.

What am I missing here.
