NTP 4.2.6p3 is packaged for Ubuntu "precise":


It is available for installation from the Ubuntu package repositories.

You should be able to see the whether or not the ntp package is
installed using the following command:

$ dpkg -l ntp

You may want to check and see if your system already has the ntp package
provided by your OS installed.

The NTP Reference Implementation source code releases, which are linked
from www.ntp.org/downloads.html and support.ntp.org/download, do not
install any initialization scripts as these are OS specific. In general
you are better off installing, and using, ntp from your OS package
management system.

'sudo ntpd' starts the NTP daemon (assuming that it in your search
path). The netstat output you included in your original article shows
that ntpd was running.
