Title:
ntpdate shouldn't be run by ifup on desktops (conflict with time-
admin's NTP options)
Status in ntp package in Ubuntu:
Triaged
Bug description:
Binary package hint: gnome-system-tools
$ lsb_release -rd
Description: Ubuntu 10.04 LTS
Release: 10.04
$ uname -a
Linux U-001 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010
x86_64 GNU/Linux
$ apt-cache policy gnome-system-tools
gnome-system-tools:
Installed: 2.30.0-0ubuntu2
Candidate: 2.30.0-0ubuntu2
It would be logical to expect, that when the time setting is set to
"Manual" in the time-admin, then time is really set manually, and
there is no synchronisation over the network
However even then there are lines like this in the system log:
ntpdate[1364]: adjust time server 91.189.94.4 offset 0.099757 sec
It is like that even after the clean install, when this setting was on
manual and clicking caused the message about the need to install NTP
support to pop out. Interesting... ntp is not installed, but something
is still trying to adjust the time with the server, on this IP, which
happens to be ntp.ubuntu.com.
Even more interesting was to observe, that after installing the NTP
support and changing the time-admin setting to "Keep synchronised with
internet servers" and even after the selecting totally different
servers, there is still this same line on the system log every time
after establishing the network connection. Of course then I discovered
that this is doings of ntpdate, which is installed by default as
dependancy of ubuntu-minimal and has this same ntp.ubuntu.com in its
configuration - and there is no way to see or change it from the user
interface. Other solution could be of course dropping the dependancy
in a way, that ntpdate would not be installed by default on standard
desktop installation, but I am not sure, if this could brake something
else and would therefore be impossible.
The server(s) defined in /etc/default/ntpdate are not visible from the
user interface and there no way to configure them.
I really do not want to describe it as "calling home" (as the setting
with ntp.ubuntu.com has no connection to user interface), but there is
possibility, that someone else would.
In some places it could be even seen as security risk, when the system
is connecting somewhere without any according configuration or the way
to configure this...
