hello list,
I am attempting to ssh via a user account setup for amanda backups from the backup server to the test backup client. AFAIK everything is setup correctly yet when I ssh as the user to the client I have to type the password. the public key is in the authorized_keys file of the client and permissions all seem correct.
Here is a verbose output of the ssh session
