How to crash a linux server

Easy!

You need to execute this as root.

First enable SysRq feature in the kernel
echo “1” > /proc/sys/kernel/sysrq

Then crash the kernel (makes a kernel dump)
echo c > /proc/sysrq-trigger

Reboot with no conditions (no disk unmount, just like pressing reset button)
echo b > /proc/sysrq-trigger

Shutdown all the processes gracefully except init
echo e > /proc/sysrq-trigger

Kill all the process brutally except init
echo i > /proc/sysrq-trigger
