Linux disable local ctrl+alt+delete

I have a linux box on a KVM – a few times I’ve switched over to it and done the ctrl+alt+del by accident (expecting an NT login) – and Unfortunately on fedora out of the box this shuts the machine down – not very good in office hours!

So I found this useful

In /etc/inittab

# Trap CTRL-ALT-DELETE
#ca::ctrlaltdel:/sbin/shutdown -t3 -r now
ca::ctrlaltdel:/bin/echo “ctrl+alt+del disabled”

No more accidental reboots….
