I'm running Ubuntu in a VM. How do I disable ntpd?

share|improve this question
Out of curiosity, why would you want to? Does it do harm when running on a VM? – Snekse Dec 19 '12 at 19:04

To stop ntpd:

sudo /etc/init.d/ntp stop


sudo service ntp stop

To prevent it from starting at boot:

sudo update-rc.d -f ntp remove

Uninstall ntpd if it is installed. You will still have ntpdate installed. (It is difficult to remove.) Prevent it from executing by adding exit 0 to /etc/default/ntpdate.
