- Setup ntp.conf. Try to find stratum 2 servers as close (ip-wise) as
possible.
- Refrain from using stratum1 servers.
- start the xntp daemon, view /var/log/messages
- use "ntpq -c peer" to show the sync status
- set the HW-clock from time to time

I saw the ntp daemon go nuts on some systems, in this case just run
ntpdate timeserver [timeserver ..]
from crontab every other hour or so. Less nice, but works too




/etc/ntp.conf
## Outside source of synchronized time
# European Stratum 1-2
server fartein.ifi.uio.no
server err.ee.ethz.ch
server ntp.exnet.com
server ntp2a.mcc.ac.uk
server ntp1.pipex.net
# Austrian Stratum 2
server ntp.austria.eu.net
server time.cso.net
##local nodes
peer other.server.inmydmz
## Miscellaneous stuff
driftfile /etc/ntp.drift # path for drift file
logfile /var/log/ntp # alternate log file




/etc/rc.config:
START_XNTPD=yes
XNTPD_INITIAL_NTPDATE="lemon.exnet.com"

crontab
0 0 1 * * root /sbin/hwclock -w

Hope that helps
Rainer
