Hello, Tony:<br>

&nbsp;&nbsp; Thanks, my TN computer get 3745, I think my TN should be correct the

clock drift.<br>

my NUT is RHEL5.2, and TN freebsd 6.2<br>

Thanks<br>

  <pre wrap="">Wang,

It could be your clock or a defect in your ipv6 stack.

I use the following utility to measure sleep drift for tahi machines.  I have a HP box with 2 Xeons that drifts 10 seconds in 5 minutes with speedstep off.

If you are not seeing a material drift, you should probably take this up with your developers as the stack may not be handling RA addresses correctly.

===============

#!/usr/bin/perl

$tm=$ARGV[0];

print "tm=$tm\n";

$tm0=time();

sleep($tm);

$tm1=time();

$tmx=$tm1-$tm0;

print "clock delta: $tmx\n";

=================

Run this for an hour,  for example:

./drift.pl 3600

If it returns a delta materially different than 3600, you probably have a clock problem, else you may have a software defect in your stack... or both ;-)

BTW, is the NUT RHEL5.2 and TN freebsd 7.0?

HIH,

Tony

Hello, all:

very strange, I close the speedstep in Freebsd computer, but it is still

failure,

could you support me finding where problem is?

Any chance that you are running on Intel chips with speedstep?  See
