Enable Remote Root Login

As root, edit the sshd_config file in /etc/ssh/sshd_config:

nano /etc/ssh/sshd_config

Add a line in the Authentication section of the file that says PermitRootLogin yes. This line may already exist and be commented out with a “#”. In this case, remove the “#”.

# Authentication:
#LoginGraceTime 2m
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

Save the updated /etc/ssh/sshd_config file.

Restart the SSH server:

service sshd restart
