At this point you cannot access the system remotely. From the ssh server direct root login is disabled. To access the system remotely you have to change the ssh configuration file.

noc:~# vim /etc/ssh/sshd_config

Look for the line 'PermitRootLogin' and replace 'no' with 'yes'. So finally it will look like

PermitRootLogin yes

Seve & exit the file.

Restart the ssh server with the following command.

noc:~# /etc/init.d/ssh restart

Note : Enabling root login through ssh is very dangerous. Don't enable unless it is really necessary. If you have to do so then make sure to impose maximum security. You can configure TCP Wrappers, DenyHosts etc. This is especially important if your router is in production environment.
