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

Emerge

# emerge sudo


Configuration

Passwordless

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

$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:

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


Either log out, and in again or restart:

$ su -c 'shutdown -r now'


Disabling Root Access By Password

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

# passwd --lock root


to access root:

$ 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.

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