Yubico Forum

I set up 2 factor authentication for remote SSH logins on my SUSE machine, using the yubico-pam module. It was working fine until I rebooted the machine. Now when I attempt a remote login I get the error:

Disconnected: No supported authentication methods available (server sent: publickey)

I think something must not be starting up properly. What am I doing wrong?

Verbose output of an ssh attempt:

I had to change ChallengeResponseAuthentication to yes in /etc/ssh/sshd_config
