NTP on a private network?

[jgbishop]

I have a number of systems, none of which can see the internet (i.e. they are on a private network). I would like to set up one of the systems as a "master" system, so that I can sync the time between all of the machines. In essence, I set the time on the master system, and all the "slave" systems update to match that time.

I assume this can be done with NTP, but I'm a little unsure as to how I would do it. Has anyone here done this kind of thing before? If so, what do I need to do to get things set up for this?

Thanks in advance!

What are the OS' on all the computers including the server?

Running ntpd on any Linux machine makes it a NTP server, so install it on all of them and just point the slaves to the master in /etc/ntp.conf.

Just to clarify, ntpd is the ntp client and server. It just depends on the settings in ntp.conf as to whether or not it allows being queried as a server. Install ntpd and then look over the ntp.conf and it should be well documented right in the conf file.

Yeah should work fine... get a GPS time receiver if you want good quality time for the master NTP server.
