How do I fix this? It seems to be timing out when it shouldn't. I'm guessing that have somehow screwed up the tape setup or networking.

I am trying to backup my Mac OSX server to a tape on my tapehost - an old Sun SparcStation. amcheck runs without errror and everything looks like it will work. It looks to me like sendsize completes OK. Then somehow the Xserver can't seem to communicate.

Total bytes written: 12902594560 (12GB, 8.5MB/s)

sendsize: pid 17804 finish time Tue Dec  6 13:30:40 2005


Then amandad seems to be waiting for an ack.

amandad: sending REP packet:

Seems like a etimeout parameter in amanda.conf that should be
increased.  you omitted the start line with the timemark, but
12GB / 8.5MB/sec ~ 1400 sec. So etimeout should be at least that large.

It could also be a firewall inbetween (or on one amanda server itself)
that does not accept the reply UDP packet after that long time.
