Hi,
One of my machines, the fileserver-with-zfs-to-be[1] has trouble
keeping correct time. Or rather, ntpd is struggling.
In /var/lkog/messages I see this:
Feb 7 12:05:54 kg-f2 ntpd[909]: ntpd 4.2.4p5-a (1)
Feb 7 12:11:16 kg-f2 ntpd[910]: time reset +1.020413 s
Feb 7 12:11:16 kg-f2 ntpd[910]: kernel time sync status change 2001
Feb 7 12:26:26 kg-f2 ntpd[910]: time reset +2.277793 s
Feb 7 12:41:29 kg-f2 ntpd[910]: time reset +2.260229 s
Feb 7 12:57:02 kg-f2 ntpd[910]: time reset +2.332972 s
Feb 7 13:21:24 kg-f2 ntpd[910]: time reset +3.659869 s
Feb 7 13:37:01 kg-f2 ntpd[910]: time reset +2.343230 s
Feb 7 13:52:24 kg-f2 ntpd[910]: time reset +2.310659 s
Feb 7 14:07:29 kg-f2 ntpd[910]: time reset +2.265705 s
Feb 7 14:23:03 kg-f2 ntpd[910]: time reset +2.335868 s
Feb 7 14:39:06 kg-f2 ntpd[910]: time reset +2.411116 s
Feb 7 14:54:32 kg-f2 ntpd[910]: time reset +2.318222 s
Feb 7 15:09:55 kg-f2 ntpd[910]: time reset +2.308120 s
Feb 7 15:25:49 kg-f2 ntpd[910]: time reset +2.388391 s
Feb 7 15:40:54 kg-f2 ntpd[910]: time reset +2.265464 s
Feb 7 15:55:57 kg-f2 ntpd[910]: time reset +2.257952 s
Feb 7 16:11:45 kg-f2 ntpd[910]: time reset +2.373325 s
and this goes on an on, forever. At any give time, no matter how long the machine has been up, ntpq ca report this:
root@kg-f2# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
kg-omni1.kg4.no 129.240.64.3 3 u 13 64 37 0.162 703.094 444.681
Note: all machines on my LAN use my firewall as the ntp server.
The ntp server runs FreeBSD, none of the other machines have any trouble keeping time.
My workstation for example:
tingo@kg-v2$ ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
*kg-omni1.kg4.no 129.240.64.3 3 u 44 64 377 0.138 4.018 0.338
(my workstatuion also runs FreeBSD 8.0-stable / amd64)
The machine runs FreeBSD 8.0-stable / amd64:
root@kg-f2# uname -a
FreeBSD kg-f2.kg4.no 8.0-STABLE FreeBSD 8.0-STABLE #2: Sun Jan 31 18:39:17 CET 2010 root@kg-f2.kg4.no:/usr/obj/usr/src/sys/GENERIC amd64
So, how can I get the machine to keep time / get ntpd synchronised?
