IP Space Migration ContinuesAll Funtoo user containers in the 8.28 IP space will be moving into our new IP space (172.97) over the next few days. If you have DNS set up -- be sure to watch your container and update to the new IP! container.host.funtoo.org DNS will be updated after the move.
Funtoo Hosting IP MoveFuntoo user containers with IPs in the 72.18.x.x range will be gradually migrating to new IP addresses this week. If you have DNS entries for your containers, please be aware that your DNS will need to be updated.
New ARM StagesNew ARM Stages, built with a new toolchain, are now hitting mirrors. Existing ARM users should re-install using these stages (dated Aug 3, 2015 or later,) rather than upgrade using emerge.
sudo allows privilege escalation for non root users to perform restricted actions while in a locked down user environment.
# emerge sudo
Instead of editing
/etc/sudoers, you may drop individual configuration files into the
The sudo configuration file is located @
/etc/sudoers. When editing this file be very careful to not introduce syntax errors. Several other linux distributions use
visudo to edit
$ su -c 'nano /etc/sudoers'
%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.
$ sudo passwd -ld 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.
Users that want bash completion with sudo need to run this once.
$ echo "complete -cf sudo" >> $HOME/.bashrc
Passing Environment Variables
To pass environment variables to the temporary root use the -E flag.
$ sudo -E echo 'hello world'
If your user has aliases you wish to use under sudo you must alias sudo with a space first:
$ echo "alias sudo='sudo '" >> $HOME/.bashrc
