I'm not quite sure how. Calling simplesnapwrap from backuphost directly seems to succeed (though I can't see the output anywhere):
backuphost:~$ ssh -i /home/ivan/.ssh/id_rsa_simplesnap -l ivan activehost sudo simplesnapwrap listfs Calling simplesnapwrap from backuphost via simplesnap using wrapcmd seems to fail: backuphost:~$ sudo simplesnap --host activehost --setname mainset --store backup/simplesnap --sshcmd "ssh -i /home/ivan/.ssh/id_rsa_simplesnap -l simplesnapuser" --wrapcmd "sudo simplesnapwrap" Here's the log from backuphost: Invoked as: /usr/sbin/simplesnap --host activehost --setname mainset --store backup/simplesnap --sshcmd ssh -i /home/ivan/.ssh/id_rsa_simplesnap -l simplesnapuser --wrapcmd sudo simplesnapwrap Store backup/simplesnap is mounted at /backup/simplesnap Lock obtained at /backup/simplesnap/activehost/.lock with dotlockfile Finding remote datasets to back up Running ssh -i /home/ivan/.ssh/id_rsa_simplesnap -l simplesnapuser activehost sudo simplesnapwrap listfs ssh exited with error 10 Logging ssh with -vvv shows that "sudo simplesnapwrap listfs" is run but no other useful info apart from exit code 10. I'm not sure if I found the correct ssh exit code definitions (why the minus sign?) but interpreting it as "invalid argument" leaves me none the wiser. https://github.com/openssh/openssh-portable/blob/master/ssherr.h#L34 Regards, ~~helix84
