So I'm running into a similar issue as (https://www.digitalocean.com/community/questions/can-t-connect-via-ssh) except SSH is already running. Essentially, I used 'sudo poweroff' to shut down my droplet so I could create an image and now I can only access it through Console Access. The difference from that question is that SSH is already running.
MobaXterm is showing "This service allows sftp connections only." when I try to SSH. The /var/log/auth.log file is showing "authentication failure". Also, and I suspect this will resolve itself, but I accidentally entered "sudo tail -0 tail /var/log/auth.log" and it appears stuck on this command - I may have to hard reboot. Any tips?
It's running Ubuntu 13.10 x64 and it's my Droplet with IP address ending with 223.
