[Pool] ntp with monlist hidden in IPMI on server mainboard

I just found a server mainboard with built in IPMI (remote configuration 
tool running in the chipset), that includes an ntp server which allows 
monlist. None of this can be disabled: not the monlist command, not the 
ntp service, and not the whole IPMI feature of the mainboard. And it 
speaks through the same ethernet jack as the server that runs on this 
hardware.

Plea to all developers: the most important feature of every automatic 
thing is the switch to turn it off!
