Hello all,
I'm a "brand new" if about amanda and mtx so please don't laugh too hard at
me. I'm trying to use our old, retired HP C1553A (it was running under Novell
with Arcserve as a backup software for a few years without any major
problems) under Linux and Amanda. I have my homework done before posting to
the list - I've read a lot, I've tried a lot of different configurations but
somehow I'm missing something and can't get amanda working for me. Any
advice, suggestions would be greatly appreciated. It's not a "Houston, we
have a problem" situation - I just hate something lying around and doing
nothing.
Sorry for the long post and many thanks in advance.
Greg Wardawy
OK, first some infos:
OS - Redhat 7.2 with 2.4.7-10smp kernel,
Amanda 2.4.2p2-4,
mtx 1.2.13-1
and some entries from my amanda.conf file:

so far so good but here is the problem:
[root@linver sbin]# su amanda -c "/usr/sbin/amcheck DailySet1"
Amanda Tape Server Host Check
-----------------------------
Holding disk /var/tmp: 15457424 KB disk space available, that's plenty
amcheck-server: could not get changer info: badly formed result from changer:
"/usr/lib/amanda/chg-zd-mtx: [: -eq:
unary operator expected"
Amanda Backup Client Hosts Check
--------------------------------
ERROR: localhost: [access as amanda not allowed from amanda@linver]
amandahostsauth failed
Client check: 1 host checked in 0.020 seconds, 1 problem found
(brought to you by Amanda 2.4.2p2)

And the standard newbie question:
What am I missing here?
Again many, many thanks. I promise to try all (not just the first working) of
your sugeststions.
