Yeah, with an offset of 54 seconds, it's a bad system. :-)
Try this (assuming 10.101.32.104 is your preferred local NTP server):
service ntpd stop
echo "10.101.32.104" > /etc/ntp/step-tickers
service ntpd start
Adding a server to the step-tickers file will tell the ntpd init
script to do an ntpdate sync against that host before starting ntpd.
In effect, that's what I did manually. When I found out that about
this problem, I did the following:
# service ntpd stop
# ntpdate ntp
# service ntpd start
(ntp is a CNAME record for our local NTP server). But after 24
hours, the system was off my more than 5 minutes. Why would it not
bind to the NTP server. Here is some output from tshark while ntpd
was running:
# tshark udp port 123
Running as user "root" and group "root". This could be dangerous.
