Hi all - a quick top post with a working solution ...
Behemoth (Fbsd dialup) uses ntpdate on initial boot (due to ancient non
Y2K bios)
uses ntpdate once every 24 hours
(crontab call)
runs xntpd with the following
/etc/ntp.conf file
Win 95 etc networked laptop/desktops
use NetTime from sourceforge
The Windoze machines are within milliseconds of the Fbsd box at all times
--------- start of /etc/ntp.conf --------------
#
# Behemoth as a ntp timeserver
# that gets itself set by ntpdate
# actions on boot and crontab
#
# do NOT define a server to listen to
## server NONE
driftfile /etc/ntp.drift
# stop xntpd from tweeking the clock as ntpdate
# does that
disable pll
------- end of /etc/ntp.conf ---------
NetTime URL
sourceforge.net/project/showfiles.php?group_id=10109
cheers
mjt
