Hi.
Today I updated our xymon server from Debian Lenny to Squeeze. After the upgrade, the NTP tests take a lot more time. We have two hosts that we test NTP on, and before the upgrade it took 0.2 seconds. Now it takes 8 seconds. This must have been caused by an upgrade of some of the OS packages/libs. Does the NTP test use ntpdate or some other application from the OS? Should I recompile Xymon after doing an upgrade like this, to link it to new versions of the libraries?

Sounds like a dns issue.
Would your resolv.conf file be messed up?

Hi
It looks correct, and the DNS lookups in xymonnet don't take longer than before. I can resolve correctly from the prompt as well.

According to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=599542 it's a bug in the Squeeze version of ntpdate. Looks like you'll have to sit it out or manually install an older version of ntpdate. I noticed because I have other issues with ntpdate no longer working when querying our 2003 DC's.

Ah, ok. Thanks for the info. I think I will just wait. It's no real problem since we are only testing ntp on two hosts.
