NTP issue


Hi Folks,

Today morning i noticed a variation in the server time about 6 mins delay. After a while it is corrected by itself. NTP is configured in the machine, i would like to know why there was a delay at that point of time.

Any help would be appreciated.

Regards,
Mani

Check your /var/log/message file for ntp errors or warnings.

If the clock gets too far out of sync, NTP will refuse to adjust it. Is it possible your machine lost its connection with the NTP upstream servers, causing it to drift for a bit? I've seen cases of this happening before. Unfortunately, in my experience NTP is none too great about logging stuff, so it might be a bit tough to track down.

Yes I have a laptop with a clock that runs too fast. After the initial sync up to current time at boot, the ntpd eventually gives up after several days; not a problem with a laptop. It will say so in the messages log.
