I am trying, without success, to setup rsync-based backups over SSH in MIAB web management.
The destination machine has:
- ssh/rsync enabled
- host name is FQDN
- the destination sub-directory is created and is writable by user
- MIAB ssh public key of the user is in the authorized_keys file of the destination user home directory (.ssh/authorized_keys)
However, when setting up the MIAB I get the following error:
Connection to rsync host failed: The hostname xxx.yyy.tld cannot be resolved.
I can do key-based login to the SSH to the destination machine over internet also with other user/key. I can even see the destination machine from terminal and the MIAB is resolving the FQDN (xxx.yyy.tld) to the correct IP via nslookup in terminal without problems.
Alternatively, I tried using the public IP of the destination machine instead of the FQDN with no success, the same error message appears.
Many thanks for any help.
