time syncronisation

Dave Elliott — Tue, 10 Dec 2002 12:34:02 GMT

Hi guys
I need to syncronise all my unix boxes to one machine, i know that this is possible but have never done it, so i have two questions.
How do i make one unix machine the central time server.
or idaelly is it possible to get the unix boxes to talk to an existing NT time server and if so how.
regards

Andrew,

You can use SAM to walk you through NTP setup, both server and client. Also take a look at man xntpd.

Oh, and "Installing and Administering Internet Services" has a section on NTP, as well. You should be able to find it on docs.hp.com.

'ntpdate' is the command to do this.

look at the man pages of ntpdate

If you are lucky, you can open up port 123, I think it is and get your time information from a true Internet source. Of course most firewall people think this is a huge risk.

If you need to rely on another Unix box, it will work okay.

If you need to work with a Microsoft Windows/NT/2000/XP time server, you may have an issue.

HP-UX 11.00 would not time synch properly against Microsoft's time server for NT/Server. It seems Microsoft didn't properly follow NTP protocols.

The good news is Doctor David Mills from the University of Delaware has links to a better program that works according to standards.

This web site is worth the look.

Go for a close NTP server as well. There is no need to pick on the armed forces for time. A close university, the Universtity of Chicago in my case works quite well for my Linux boxes at home.
