How do I actually use rmt? I want to backup a guest domain on a T2000 using a tape drive on the primary domain. Both domains run OpenBSD 6.0.
The way I read the mt manual page, I should be able to do (from the guest, as root) > mt primary:/dev/rst0 status and this should deliver the command to rmt on the primary, execute the command and return the results, identical to if I did > mt -f /dev/rst0 status on the primary. Instead, it just hangs. Are there some preconditions, somewhere? Like - do I need to start rmt on the primary, somehow, or hack around with inetd.conf? or is it all about hosts.allow? Is there a magic FAQ for this stuff? Or am I the only person that has used magtape since it was 556 bpi? Help! Thanks.
