Most of our servers are accessible only via ssh with a root key. Does
amanda work in such a setup or does the amanda user have to have regular

accept logins via ssh and now amanda doesn't seem to be able to get
there and we get the following message:
WARNING: /host/: selfcheck request timed out. Host down?
Actually, the amanda user doesn't ever need to log in; all communication
between the server and its clients goes over amanda's own protocol.
What amanda needs are a few open TCP and UDP ports between client and
server, and a simple host-based authentication in the amanda user's
homedirectory, in a file .amandahosts.
Since I gather your backup worked before, I wonder whether your collegue
mightn't have installed a firewall at the same time. A quick search in
this mailing list's archives will give you a complete solution with
iptables, or else just open TCP and UDP between your amanda server and
the amanda client in question.
