Today drift is 60 and offsets are around 8. Looks good.
You know what's good?
from: ntp3.lordynet.org NetBSD-6.1, i386, ntpd 4.2.6p5:
$ cat /var/db/ntp/ntpd.drift
-9.722
from ntpq -crv
offset=-0.061
Your ntpd 4.2.4 is from 2008 through 2009 and offsets with
that version might not have been much worse than from 4.2.6p5
but correction of drift above 50 ppm was not good or even
impossible. Ntpd 4.2.6p5 also converges to a reasonable low
offset much faster after ntpd is restarted. I have an idea
that ntpd 4.2.8 is very near to release.
That's great to know, thanks.
I will speak with the manufacturer and see if a newer version can be
adopted. It's good to know that it may well be a limitation of the NTP
version being used.
Today I've been told that on newer machines I can enable the HPET (high
precision event time) in the BIOS if available and that should give a
better clock to begin with.
Your problem may not be with the setup of ntpd and you really
need to know what cpu optimisations, if any, are enabled. Some
optimisations for energy consumption are incompatible with
running an ntpd service. I can't help you with bios settings
or diagnostics for your motherboard settings. You might find
some information in dmesg but again that requires familiarity
with your hardware.
I will check the CPU optimisation as soon as I'm in front of one of
these servers.
Thanks for your help David
Antonio
