[KLUG Members] remote dump not working

[Jason Edward Durrett]

Hi All,

I recently upgraded the server(got a new machine - but migrated configs 
from the old machine) that handles my tape backup and I am having 
trouble with my backup scripts on other servers.

The remote script is rather simple:

#!/bin/sh
export RSH=/usr/bin/ssh
/sbin/dump -0uanL -f root at 10.3.1.3:/dev/nst0 /
(...)

When the script runs I get this:

 DUMP: Connection to 10.3.1.3 established.
  DUMP: Date of this level 0 dump: Mon Oct 29 23:12:58 2007
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping snapshot of /dev/ar0s1a (/) to /dev/nst0 on host 
root at 10.3.1.3
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 41180 tape blocks.
  DUMP: /dev/nst0: Input/output error
  DUMP: Cannot open output "/dev/nst0".

/dev/nst0 does exist on the machine that is attached to the tape drive 
and that machine executes the dump just fine.

The machine attached to the tape drive is running Debian Etch as was the 
machine before - perhaps in the migration I missed something.

It has been years since I had to worry about this script running right 
and I think I might be overlooking something really basic . . . any ideas?

Thanks,

Jason
