I quicker way to take down a machine is this: # dd if=/dev/random of=/dev/port bs=1M count=2 Should take a little less than a second to kernel panic your machine. As Jim mentioned, have a look at limits.conf to help fix your fork bomb problem...just don't set it too low!! (if someone has root access, they have *several* ways to take down your machine, including 'reboot', and 'shutdown'...)
