Our application runs on Ubuntu 12.04 precise. On this server, we have both ntpdate and ntp. How to enable and disable ntp service on-demand?

I tried

sudo update-rc.d -f ntp remove/default


sudo update-rc.d ntp enable/disable

, but when I reboot the server the ntp service starts running! I suspect ntpdate to start the ntp service on reboot. I removed the ntpdate package from one of my experimental server- then ntp didn't starts on reboot after issuing the command update-rc.d ntp disable.

Is there a way to control this or is there way to permanently disable ntpdate?
