Re: NTP problem - Clock too fast for NTP to keep up?

Hi Gene,

I too had the fast clock problem, and by tickling the tick counter
with the 'tickadj' command, was able to stay well within 1 second
per hour.  The bare command will return the current tick value,

Ahhhh the light dawns. I didn't realise it was a program, I thought it was an option for NTP.


Lower.  Default is 10000.

Setup an ntpdate to hit the net for the time, say hourly.  Put
a tail on the log so you can see how far off it is.

Well I've reverted to the ntpdate every 2 mins so this should be pretty fast to see the difference.


Set tickadj to 9950 and see if it still gains time, if it does,
try 9925.  Here, that was enough to make it start running slow,
and I wound up in the 9926 to 9927 area for get the thing running
within range of the soft only, no step adjustment in ntpdate.

Once fine tuned, stick that tickadj in your /etc/rc.d/rc.local file.

Thanks for the suggestion :)

This is what I am currently seeing
Feb 10 16:04:04 krusty ntpdate[8692]: step time server 202.173.151.129 offset 2.372749 sec
Feb 10 16:05:38 krusty ntpdate[8748]: step time server 202.173.151.129 offset -22.546148 sec
Feb 10 16:05:59 krusty ntpdate[8754]: step time server 202.173.151.129 offset -2.965399 sec
Feb 10 16:07:44 krusty ntpdate[8770]: step time server 202.173.151.129 offset -16.632290 sec


As you can see it is a pretty rapid time gain :(
