[ntp:questions] Problem with xntp after reinstall on openSUSE 10.3

[Marc Muehlfeld]

Hello,

I run a xntp server on Suse 10.0 for the last 2 years. Last week I reinstalled 
the server using openSUSE 10.3. I setup the server to run chroot (in 
/etc/sysconfig/ntp) like before and use the same ntp.conf. But now the time is 
allways wrong after some hours.

Meanwhile I took all restrict rules out of the file (but I had them in before 
too and it worked for a long time), but still have this problem. This is the 
current ntp.conf I use:


server 127.127.1.0              # Local clock
fudge  127.127.1.0 stratum 10   # Local clock is unsynchronized (stratum 10)

server 0.de.pool.ntp.org        iburst prefer
server 1.de.pool.ntp.org        iburst
server 2.de.pool.ntp.org        iburst

driftfile /var/lib/ntp/drift/ntp.drift
logfile   /var/log/ntp


About two minutes after starting xntpd:
# ntpq -p
      remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
  LOCAL(0)        .LOCL.          10 l   21   64    1    0.000    0.000   3.906

About 5 minutes after startup it fall back to local and ntpd shows:
# ntpq -p
      remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================

The ntp logfile just says:
# cat /var/log/ntp
15 Oct 17:31:09 ntpd[6534]: synchronized to 62.52.175.213, stratum 2
15 Oct 17:31:09 ntpd[6534]: kernel time sync status change 0001
15 Oct 17:35:11 ntpd[6534]: synchronized to 85.25.132.119, stratum 2
15 Oct 17:35:15 ntpd[6534]: synchronized to LOCAL(0), stratum 10


After 2 days my ntp server has allready a delay to the real time of about 20 
minutes. Any idea why it allways fall back to local? The internet connection 
is allways available.
