Ubuntu root user access

Ubuntu by default has only root access which can be gained using sudo instead of an actual root user. Root is created without a password and can not be logged in.

One way to gain root prompt is to launch a shell as root. Type "sudo sh" at the prompt. You can also set a root password using the "passwd" command. Just type "sudo passwd" at the prompt and create a new root password.
