My Ubuntu 10.04 server has ntpd running with default configuration.
Problem is it doesn't sync. Syslog shows:
kernel time sync status 2040
When I try stopping ntpd and running ntpd -q it does work.
So I'm guessing the difference lies in the way ntpd is configured to run as a service.
This is how ntpd is running as a service:
/usr/sbin/ntpd -p /var/run/ntpd.pid -g -u 102:104
Other things I've tried is running ntpdate, which worked, but afterwards restarting ntpd again fails to sync. Also tried adding more servers, which didn't help:
ntpq -p shows:
remote refid st t when poll reach delay offset jitter

How can I tell why ntpd is failing to sync when running as a daemon as opposed to when running with -q?
Update
Inside ntp.conf I have the following servers:
server ntp.ubuntu.com
server pool.ntp.org
I also tried adding:
server 0.fedora.pool.ntp.org iburst
server 1.fedora.pool.ntp.org iburst
server 2.fedora.pool.ntp.org iburst
server 3.fedora.pool.ntp.org iburst

Turns out that simply restarting the NTP service doesn't in fact try to sync the clock. That error message is still unclear to me, but nevertheless about 15 minutes after restarting the service the clock is synced properly.
