I set up NTP about 2 years ago on my 2 machines, with help from the ntp questions mailing list. The default /etc/ntp.conf has a lot of uncommented lines, and I was told that in most cases all you really need are the server lines, and the driftfile one. I commented out all the other lines, and just left the server lines that I'd set up, and the driftfile line. Started the ntp daemon, ran ntpq> pe from time to time, and eventually the servers synched up. It does take a bit of time to synch, and many hours before the driftfile "stabilises", for want of a better word. As a matter of consideration for the Internet time servers it is also suggested, if you have a few machines on a LAN, to set one machine up to access Internet time servers, and set up the other machines to get their time rom that machine, which is what I did. I only have 2 machines on the LAN, but with a bunch of distros that run on each of them, so I set up /etc/ntp.conf for all the distros on machine "A" with just the Internet timeserver lines, and the driftfile one. All my distros have static IP addresses, so for the distros on machine "B" the only lines uncommented are the server lines, and the driftfile one. As an example for Fedora 7 on machine "B", and as I havn't got around to adding the lines for the other distros that run on machine "A", there is just one server line. server 192.168.0.230 plus the driftfile one of course. Both machines access the Internet by means of a Smoothwall Express2 firewall, and serial modem. The Smoothwall sorts out it's own time, and checks every 3hrs from a range of Internet time servers. By the way for the 1st time with the Fedora 7 install, I've left Selinux enabled (enforcing), and am having no problems with ntp on it. Just some comments on my setup, that may or may not be helpfull. Nigel.
