You may be having trouble with your ssh known_hosts file. Clear out or rename temporarily the ~/.ssh/known_hosts and try the ssh login again. It should then ask about you connecting to the remote host for the first time (answer yes).

After entering root at the login: prompt, the console screen clears & it's back with the login prompt again without prompting for password. I would not want to reboot this box if possible as it's production. Haven't tried ssh into it yet but anyway, I only recall there's root login id in this box, there's no other login id & since it's a hardened box, I can't ssh into this box using root. any other idea? There's no alert from the monitoring tool (which usually we'll get if the filesystem or memory utilization or CPU exceeded the defined thresholds or ping fails to this box).
