Hello!
I have all my pictures in a RAID 1 array, but I also wanna back them up with Rsync to another NAS, a Netgear ReadyNAS 1100 to be precise.
Since the destination is a bit old, the only SSH cipher they offer are diffie-hellman-group-exchange-sha1, diffie-hellman-group14-sha1, and diffie-hellman-group1-sha1.
I did a SSH config file on the OMV machine for both the Backup, and root user, but, as you can see in the error, it refuses to connect because by default SSH doesn't accept the remote cipher's.
Here's my scheduled task command, run by the Backup user: rsync -av --relative --progress --stats --no-relative -e ssh -F /home/Backup/.ssh/config /srv/dev-disk-by-uuid-000c0481-55dd-4e44-b0ac-9bb3d7ed0513/ root@192.168.70.200:/c/photos/
The SSh config file both for the Backup user, and root user:
cat .ssh/config
Host 192.168.70.200
KexAlgorithms +diffie-hellman-group1-sha1
