That's not always the case, e.g., on one machine it is currently a candidate: > remote refid st t when poll reach delay offset jitter > ============================================================================== > +s51 69.25.96.13 2 m 283 1024 377 0.276 4.844 0.011 > +s11 128.9.176.30 2 m 41 64 377 0.203 -1.618 0.061 > *s12 204.123.2.5 2 m 56 64 376 0.001 -2.596 0.047 > -s52 204.9.54.119 2 m 22 64 376 0.001 -12.454 0.058 > > ind assID status conf reach auth condition last_event cnt > =========================================================== > 1 36023 7424 no yes ok candidat reachable 2 > 2 36024 7434 no yes ok candidat reachable 3 > 3 36027 7634 no yes ok sys.peer reachable 3 > 4 36028 7314 no yes ok outlyer reachable 1 and sometimes is even a peer: > Aug 30 07:23:01 XXX ntpd[3989]: synchronized to <s51's address>, stratum 2 What you can notice, anyway, is that on those machines that show the problem, the peer is "flapping" a lot: > Aug 30 05:04:43 XXX ntpd[3989]: synchronized to <s51's address>, stratum 2 > Aug 30 05:10:39 XXX ntpd[3989]: synchronized to <s12's address>, stratum 2 > Aug 30 05:56:12 XXX ntpd[3989]: synchronized to <s51's address>, stratum 2 > Aug 30 06:05:21 XXX ntpd[3989]: synchronized to <s12's address>, stratum 2 > Aug 30 07:23:01 XXX ntpd[3989]: synchronized to <s51's address>, stratum 2 > Aug 30 07:44:32 XXX ntpd[3989]: synchronized to <s12's address>, stratum 2 Does this add any useful information?
