bru

[Patricia Monger]

I have tried and failed to use bru to back up files from an Iris running
Irix 3.2.1 to any device attached to a sun 3/260 (1/4" 60 mbyte cartridge
tape drive, 1/2" reel tape drive, exabyte tape drive).  The iris is named
in the /.rhosts and /etc/hosts.equiv file on the sun.  I can do a remote
tar, using rsh, so I don't believe access to the remote host is the problem.
the error I get from bru is

bru: "<host>:/dev/rmt0": can't open archive: I/O error

Is this one of those things that everybody but me already knows doesn't work?
or already knows how to make work?
thanks, patricia monger
