Hello All gurus of the SSH authentication.
I have been fine in the past with authentication. I am longer been able to authenticate when I ssh to the TN box or authenticate my RSYNC via my key. There were 2 changes that I have made. Change 1) upgraded from to 13.0-U5.1 from I believe was U2. 2) I stopped using SMB and CIFS and moved to just NFS as I want to retain my file structure. I suspect the later as I had made several changes to permissions. Access is from the LAN and not remote.
I had read several good suggestions of what to try, but I still have an issues (ha, don't we all :) ).
In the auth.logs I can see:
Authentication refused: bad ownership or modes for file /mnt/NAS_Drive_01/Backup/Familyroom/.ssh/
authorized_keys.
I can confirm that if I 'cat' that folder, the key does match what is in the GUI as well as the client machine's public key.
My dir's permissions settings:
drwxr-xr-x. Via CLI ls -l, he Gui seemed to not match.
I have stripped ACLs from the pool, set the Access mode to 755, and reset the user and the group and applied excursively. Under SSH settings I have removed password authentication and restarted the service ( and the VM as well )
I can view all dirs/files that are shared via NFS in the pool, I just cant authenticate via SSH or RSYNC.
Any additional check to try is much appreciated
Regards and thank you for your time
