enable/disable ntp service on ubuntu 12.04
Solution 1
Coming in a couple years late, but hopefully it will help.
This will fix the unexpected interaction between ntpdate & ntp:
rm -f /etc/network/if-up.d/ntpdate
Then when you do a "update-rc.d ntp disable", ntp won't start on reboot.
Solution 2
The ntpdate command is a program that can be used to set the system time one off. There is nothing to enable or disable with ntpdate and nor does it control the ntp service.
The ntp service controls the action of the ntpd daemon. This can be disabled with the command
update-rc.d ntp disable
and then you can start and stop it using the service command
service ntp start
service ntp stop
On an Ubuntu system I have to hand with both ntp and ntpdate installed, this all works as expected. Disabling the ntp service and rebooting, the service remains off.

Our application runs on Ubuntu 12.04 Precise. On this server, we have both
ntpdate
andntp
.How to enable and disable the NTP service on-demand? I tried
# sudo update-rc.d -f ntp remove/default
and
# sudo update-rc.d ntp enable/disable
commands, but when I reboot server the
ntp
service starts running!I suspect
ntpdate
is startingntp
service on reboot. I removedntpdate
package from one of my experimental server, thenntp
didn't start on reboot after issuing:# update-rc.d ntp disable
Is there a way to control this? or is there way to permanently disable
ntpdate
?-
ntphelp almost 11 yearsI see ntpdate is starting ntp service on interface up. once I put
exit 0
on top of the script/etc/network/if-up.d/ntpdate
everything is working as intended. -

ntphelp almost 11 yearsI followed the same steps but not working for me! I also tried by freshly installing ntpdate and ntp but same result- ntp is stating on reboot. Is there a way to find in logs who is staring ntp? I see all the ntp rc files are in kill mode after issuing
update-rc.d ntp disable
command! -
