WARNING: THE NEXT KEY COMBINATION WILL CRASH YOUR COMPUTER

Ok, I get that this is an administrative tool and all, but I realized that any user can do ALT + SysRq + C. This link explains what I'm talking about.

But only as root I can do something like echo c > /proc/sysrq-trigger and have it actually crash the system.

If someone has physical access they can just plug in a keyboard and crash the computer (or server), but it would be even harder for them to get root privileges in a terminal, right? Is there a specific reason as to why it works as non-root from a keyboard but only as root from a console?

This is not what I'm looking for. It is talking about an issue with the Fn part on keyboards. It doesn't even allow you to do it with sudo. You have to first su root.

BTW:
sysrq won't reboot with a keystroke, but will with echo "b" > /proc/sysrq-trigger is not what im looking for; it is talking about an issue with the Fn part on keyboards

Side note:
it doesnt even allow you to do it with

sudo 

you have to do

su root 

first
