Vicky’s server guides

If you are on cpanel (or any other centos server) and need the security feature that root cannot log in via ssh (I will cover this elsewhere) you can do it by adding new user by using these commands:

# adduser testuser
# passwd testuser

that will create the user “testuser” and prompts you to enter his password

With this you would not be able to su to root, therefore you need to add this user to wheel group by using command:

# usermod -f wheel testuser

Voila, now user “testuser” will be able to su – to root and you can disable direct root login in your ssh configuration.
