On killing stuff -- with Elephants.

[Donn]

Hi all,
On the subject of killing stuff when a machine is too far gone and you begin 
to eye the power switch with a sad look, this recipe works a bomb!

I found this online somewhere and can't find the source:

SKINNY ELEPHANTS

Raising Skinny Elephants Is Utterly Boring
Or, I remember it as:
Really Stupid Elephants In Ugly Boxers (go figure :) )

Here is how you do it. It's like playing those really hard chords on a guitar, 
but it's not supposed to be easy!

Alt+SysRq+r  ( The LEFT Alt key ) ( SysRq is on the same button as print 
screen )
Alt+SysRq+s
Alt+SysRq+e
Alt+SysRq+i
Alt+SysRq+u
Alt+SysRq+b

Give a little time between keystrokes. Very NB!

The r stands for put keyboard in raw mode
The s for sync the disk
The e for terminate all processes
The i for kill all processes
The u for remount all filesystems read only
The b for reboot the system

If your filesystem is Ext3 or ReiserFS and on reboot it wants you to do a 
filesystem check, don't touch any key when it asks you to press "Y" and let 
it recover the journal automatically.

NOTE: For the skinny elephants to work you need to have the sysrq-key enabled 
in the kernel. (CONFIG_MAGIC_SYSRQ)
You can check if it is enabled by typing 'ls /proc/sys/kernel/sysrq' if it's 
there, it's enabled.
