Hi,
i searched around in the archive without success for my wish:
i would like to backup data over unsecure network on an host with
secure user authentication using nbd with dmcrypt. from my point
of view, something like this would be nice:
# nbd-client ssh://myuser@backup.server/my/home/image /dev/nbd0
in the background i would expect something like:
socat TCP-LISTEN:1234 'EXEC:ssh myuser@backup.server nbd-server 0
/my/home/image -d'
nbd-client localhost 1234 /dev/nbd0
...(my local) crypt setup...mount filesystem...
unfortunately, nbd-server fails on the sshd-pipes with the getpeername() call
(for evaluating the IP-address to replace the %s in the filename). On the other
side it would be nice if nbd-client directly works on stdio handles without
wrapping communication through TCP.
Key issue for me:
i don't want to have open TCP ports (opening race conditions when connecting)
on the local as well as on the remote host
did i miss an already existent solution?
Best regards,
Olli
