sudo allows privilege escalation for non root users to perform restricted actions while in a locked down user environment.

Emerge

root # emerge sudo

Configuration

Passwordless

The sudo configuration file is located @ /etc/sudoers.

user $su -c 'nano /etc/sudoers'

Remove the # in the line....

%wheel ALL=(ALL) NOPASSWD: ALL

Add your user to the wheel group to enable sudo:

user $ su -c 'gpasswd -a $USER wheel'

Either log out, and in again or restart:

user $ su -c 'shutdown -r now'
Disabling Root Access By Password

To better secure a system, one may desire to disable root logins by password.

root # passwd --lock root

to access root:

user $ sudo su

Root can also be accessed by logging in via ssh keys, or as a restricted user then sudo su as above.

Bash Completion

Users that want bash completion with sudo need to run this once.

user $ echo "complete -cf sudo" >> $HOME/.bashrc
