NTP test runtime increase after OS upgrade
list Johan Sjöberg
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? /Johan

Sounds like a dns issue. Would your resolv.conf file be messed up? Paul Root Lead Internet Systems Eng Qwest Network Services

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. /Johan

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. -Marijn

It's no real problem since we are only testing ntp on two hosts. /Johan
