Try this: dpkg -l ntp ntp-simple

You should see something like this (though the versions may be

The Debian package manager will automatically start ntpd after the
package in installed. Assuming, of course, that the installation
succeeded. You should not have to do anything other than install the
package and provide the names of the time-servers that you want to use
when prompted during the installation process.

Does 'ps ax | grep ntpd' show anything? (I don't recall if you mentioned
this earlier)

ntpd != your desktop clock

>>># man ntp

There is no ntp man page, but 'man ntp' should display the ntptime man page.

Man pages, at least in category 1 and 8, usually have the same name as
the piece of software that they are documenting. So for ntpd try: 'man

BTW: You can see the list of man pages in any installed package with the
following command:

	dpkg -L package-name | grep man

The ntpd man page should be available if you have installed one of the
ntp daemon packages.

BTW: The NTP Project releases all of the NTP documentation in HTML
format. You may find a link to the Official NTP Documentation at

On a properly configured Debian system you _will_ be prompted for
the time servers to use when you install the ntp package and one of
the supporting ntp daemon packages (e.g. ntp-simple). And a suitable
ntp.conf is generated during the installation process. In my experience
this just works.

You may reconfigure ntp-simple (as root) with the following command:

	dpkg-reconfigure -p low ntp-simple

If you feel that your ntp package installation failed you may re-install
them with the following command:

	apt-get --reinstall install ntp ntp-simple

If this does not work there may be some other issues with your Debian
installation that need to be addressed.

Please feel free to stop by the NTP IRC channel (#ntp on
irc.freenode.net) for assistance.
