Akk.. and the one other bit of magic that makes it work Xntpd and ntpdate want to use the same port 123, which gets them knotted.. So the entry in crontab is NOT just ntpdate aaa.bbb.ccc.ddd but instead is /root/bin/ntpcron which is a script as follows #!/bin/sh kill `cat /var/run/xntpd.pid` sleep 1 ntpdate aaa.bbb.ccc.ddd sleep 1 xntpd -p /var/ruun/xntpd.oid Ie drop off the xntdp daemon while we tweek the systems clock cheers again mjt ----- Original Message ----- From: "MurrayTaylor" <mjtlx@ozemail.com.au> To: "Chris Dillon" <cdillon@wolves.k12.mo.us>; "Joe & Fhe Barbish" <barbish@a1poweruser.com> Cc: "FBSD Questions" <questions@FreeBSD.ORG> Sent: Monday, January 14, 2002 8:43 PM Subject: Re: ntpd as time server? > 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 > > ----- Original Message ----- > From: "Chris Dillon" <cdillon@wolves.k12.mo.us> > To: "Joe & Fhe Barbish" <barbish@a1poweruser.com> > Cc: "FBSD Questions" <questions@FreeBSD.ORG> > Sent: Monday, January 14, 2002 5:00 AM > Subject: Re: ntpd as time server? > > > > On Sun, 13 Jan 2002, Joe & Fhe Barbish wrote: > > > > > The final option is ntpd.
