Hello fellow amanda users,
I've had amanda up and running successfully for quite a while
with several flavours of RedHat linux, however I recently added
another RedHat 7.0 client to the mix, and I have an interesting problem.
If I have no entries in the clients /etc/dumpdates file, the amanda server will do a
level 0
backup of the client, as it well should. However, after an entry is written to
/etc/dumpdates
then the client consistently times out when "sendsize" is executed.

So the only way I can get a backup of this client is to empty the contents
of /etc/dumpdates. If I don't do that then amanda consistently fails,
and it always indicates a level 0 failure, even though it sucessfully did
a level 0 the previous day.
####
FAILURE AND STRANGE DUMP SUMMARY:
"client" /dev/hda6 lev 0 FAILED [Request to "client" timed out.]
####
It seems to definitely be a "dump" problem and not an "Amanda" problem
but I've not come across this before, has anyone else?
