All,
I am having great difficulty getting xntp (4.1.1-121) to work on a SuSE Linux 8 (2.4.19-64GB-SMP). The hardware clock seems to maintain the proper time but the system clock drifts upwards over the course of the day upwards of six seconds.
The drift file never updates and continually shows a 0.000. Never changing out of that.
This is the output from an ntpq -c rv -p.

The clock frequency, jitter, and stability never change. We have other servers that clock off of the same server we are running and they do not have problems.
Below is the ntp.conf for this system.
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
# Permit all access over the loopback interface. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.

# Specify the key identifier to use with the ntpdc utility.

I have ensured that the drift file was accessible and moved it to /tmp for testing. It has rw permissions across the board. I have tried both with and without the restrictions and with different flags on the restrictions with no luck.
Any assistance you can provide on this would be welcome.
