A while now I'm having some problems with my ntp setup.
I have simple comfig file:
$ cat /etc/ntp.conf
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp.log
server 0.nl.pool.ntp.org
but the offset is usually around 2000 and the jitter hovers around 700:
$ ntpq -np
remote refid st t when poll reach delay offset
jitter

*217.67.231.25 193.67.79.202 2 u 43 64 377 23.005 2073.00
719.806
In ntp.log I continuously see lines like this:
23 Feb 19:09:51 ntpd[27664]: time reset +2.393091 s
23 Feb 19:21:52 ntpd[27664]: synchronized to 217.67.231.25, stratum 2

23 Feb 21:04:48 ntpd[27664]: synchronized to 217.67.231.25, stratum 2
23 Feb 21:14:26 ntpd[27664]: time reset +2.400477 s
This goes on and on and on. And regularly ntp stops having connection,
reach goes to 1 and builds up again. Never that it is a poll that's been
missed, it is always back to 1 as if ntpd has started itself up again.
I'm using ntp 4.2.4p4 on a Ubuntu box. Linux kernel 2.6.24.
What's wrong in this setup?

Maarten
