Yes, but WHY???

You can configure a computer so that NO-ONE can log in. But anyone with physical access to the machine can change it back.

What problem are you trying to solve?

I'll link you to the documentation instead.

That way, you will have a better understanding of what you're doing.

Make sure you set up sudo first. Then, just lock the root password:

Code:

passwd -l root

I'm not sure whether completely denying login access for root is a good idea. Depending on your circumstances in terms of the physical access to the system, maybe the following is appropriate:

- Restrict root access to the physical console attached to the system by having

Quote:

console

in /etc/securetty

- Disable root login via ssh by setting

Quote:

PermitRootLogin no

in /etc/ssh/sshd_config

Hope this helps.
