Allow root SSH on Ubuntu

By default, root SSH access in Ubuntu server is not set. If you are trying to ssh to your server with your root account and password, you will receive an access denied error. In order to overcome this limitation, you will need to edit the file /etc/ssh/sshd_config to allow root password logins through ssh. As shown below, comment out #PermitRootLogin without-password and add PermitRootLogin yes.

# Authentication: LoginGraceTime 30 #PermitRootLogin without-password PermitRootLogin yes StrictModes yes

Once the file is saved, you will need to restart the ssh daemon in order for the changes to take affect using the command below.

service ssh restart

After the ssh service is restarted, you should now be able to login through ssh using your root account and password.
