Not really. A second best solution might be to use a separate password less key, with restrictions imposed on it in ~/.ssh/authorized_keys. On cheddar.halon.org.uk you could put something like this in your authorized_keys file. command="/usr/bin/python /usr/bin/rdiff-backup --server --restrict /home/chris/backups/isbd",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa AAAAB3NzaC1yc2EAAAA... That way there will be less of an issue if the ssh key is "stolen". Example on running rdiff-backup with an explicit ssh-key: rdiff-backup --remote-schema 'ssh -i /home/foo/.ssh/backup2cheddar %s rdiff-backup --server' /home/isbd ch...@cheddar.halon.org.uk::/home/chris/backups/isbd Good luck! // Andreas
