So, two machines that want to talk to one another (e.g. amanda server and amanda client) need to
know how to address one another. If you don't have DNS within your private network, and you don't
have fixed IPs assigned (that you know) within the DHCP server, then it seems to me you are really
creating difficulties. Even on my home network, I set fixed IPs so that I can do things like ssh and
rsync from one Mac to another. Without that, you're dependent on network chatter and some vendor's
auto discovery mechanism. But that's not a protocol that's going to work with Amanda. You might
jerry-rig a complicated method for auto-discovery and transmitting information to the Amanda server
that gets put into /etc/hosts; but, then, why not just implement fixed IPs and/or DNS. It seems like
the more traditional and well documented solution.

Just for reference, if you are running in a private network without
dns lookup, then you should put all the machines you want to backup
into /etc/hosts. That's what I had to do when my Amanda server was
on our private net and had no public address.
Can /etc/hosts be automatically updated if clients get their
IP addresses dynamically with DHCP?

That doesn't mean you don't have other issues that have to be dealt
with. There is a general trouble shooting page for possible issues
that result in "selfcheck request failed" --
