NTP issue for samba3 systems

UCS - Univention Corporate Server
#1

As part of the Samba4 UCS domain, I have two-* samba3 systems that are used for file shares.
In Nagios I am seeing the following error for both of these systems, and I am unsure of how to resolve this.
NTP CRITICAL: No response from NTP server

#2

Hello,

that sounds like the NTP daemon is not running on those systems (ps aux | grep ntp). You should have UCR ntp/autostart set to yes to start ntp at boot time.

#3

The NTP service is set to Autorun within UCR
However, the NTP service is not running - even after a reboot. See below:



#4

Hello,

as per default the NTP Server is only configured on systems with a Domain Controller role and not for example on a memberserver.
I would suggest, that you disable the Nagios NTP Check for this machine. This behaviour is documented as well in our Bug Tracker, [bug]25128[/bug](german only) and fixed in UCS 3.0-1.

#5

I guess not fixed if the system is upgraded from 3.0.0 to 3.0.2
Perhaps only for new installs?

#6

Yes, it was only fixed for new installed systems. You can install the ntp package on the member server:

univention-install ntp

Or you remove the Nagios ntp check for the member server in the Univention Management Console.

Best regards
Stefan

#7

It appears that by default in UCS, nagios is not configured to check external commands.
I guess I will have to tweak the default setup.
