In any case there is no value in having a local clock configured on a leaf node and it may also cause problems by excluding a true chimer. > 15 Jul 16:39:25 ntpd[15930]: frequency error -512 PPM exceeds tolerance 500 > PPM This is end stop, probably because it tried to track the lost interrupts on lovejoy. > 15 Jul 16:43:42 ntpd[15930]: synchronized to LOCAL(0), stratum=5 It's abandonded lovejoy. Because you have the fudge command in the wrong place, it is ineffective, so the local clock is at its default stratum. > So it looks like it's synching to lovejoy [ 192.168.1.14 ] but at a > very low strat. And those PPM errors go away afer a nice ntpdate on > lovejoy. That's because lovejoy is currently synchronised to its local clock. If you don't want this to happen, don't configure a local clock on lovejoy. > The windows boxes, forget it, they dont want to synch at all. Most of the time, lovejoy isn't synchronised. You need to: - fix your lost interrupt problem. - remove the local server from the leaf nodes. - seriously consider removing it from the LAN server (it is often not needed) or increase the number of servers with true time to be enough to outvote it. (Note that having just one server will work, but you shouldn't configure a local clock at the same time. It will give no protection against a mis-operating server.) _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
