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


# emerge sudo



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

$ su -c 'nano /etc/sudoers'

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.

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