If you add this option to the kernel config file and recompile, it will make CTRL+ALT+DEL a gone case, so noone, even you as root, will ever reset the system with those keys. options SC_DISABLE_REBOOT #Disable reboot by CTRL+ALT+DEL For the shutdown, it should not work for any user, unless you have given them that ability to do that in 'sudo' - please think about sudo, it is in the ports tree -- /usr/ports/security/sudo=20 /usr/local/etc/sudoers is the file to grant such privileges but you just don't edit it using any other text editor. You must use the command 'visudo' as root to edit.
