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

Unfortunately, this wasn't caught as a problem until it was too late too fix it. In 3.3, we still use the new features added in 3.2, but we fall back to the 'standard' rmt protocol if we don't see an indication that the remote understands the new protocol. So, about all you can do until you upgrade is to fall back on something like: bru -cvfb 32 - files | rsh host dd bs=32 of=/dev/rmt0 (I'm a bit hazy on this, since it has been a while, so I may have erred on the finer points.) -- Dave Olson Life would be so much easier if we could just look at the source code.
