Hi,
I have a system running Debian oldstable with Nagios-Plugins 1.4.15. A
few weeks ago, my check_ntp_peer checks have started acting up:
$ /usr/lib/nagios/plugins/check_ntp_peer --hostname=2001:1b18:f:4::2 --warning
3 --critical 5 --jwarn 10 --jcrit 20 --twarn 2: --tcrit 3: --swarn 2 --scrit 2
-v
3 candidate peers available
synchronization source found
Getting offset, jitter and stratum for peer e20a
parsing offset from peer e20a: error: unable to read server offset response.
parsing jitter from peer e20a: error: unable to read server jitter/dispersion
response.
parsing stratum from peer e20a: error: unable to read server stratum response.
NTP CRITICAL: Offset unknown, jitter=-1,00, stratum=-1, truechimers=6|
jitter=-1,00;10,00;20,00;0,00 stratum=-1;2;2;0;16
truechimers=6;0;0;0
The server itself is reachable and gives plausible answers:
$ ntpq -c pe 2001:1b18:f:4::2
remote refid st t when poll reach delay offset jitter

This behavior does not happen with all of my check_ntp_peer checks. I
have not yet found out under which circumstances this behavior happens.
For your reference, I have currently opened the ntp server on the IPv6
address listed above for in-depth queries from anywhere.
What is going wrong? Is this a bug with check_ntp_peer?
Greetings
Marc
