How do I make sure the local clocks can be outvoted by real clocks? Also, here is the result from debug: [16:53:13] ind assid status conf reach auth condition last_event cnt [16:53:13] =========================================================== [16:53:13] 1 58883 9424 yes yes none candidate reachable 2 [16:53:13] 2 58884 963a yes yes none sys.peer sys_peer Remote Server: [16:53:32] associd=58883 status=9424 conf, reach, sel_candidate, 2 events, reachable, [16:53:32] srcadr=144.190.31.2, srcport=123, dstadr=144.190.0.2, dstport=123, [16:53:32] leap=00, stratum=2, precision=-18, rootdelay=0.519, rootdisp=2.289, [16:53:32] refid=40.14.0.254, [16:53:32] reftime=d054ca24.51858b5a Mon, Oct 4 2010 21:48:20.318, [16:53:32] rec=d054ca2f.09647cd3 Mon, Oct 4 2010 21:48:31.036, reach=377, [16:53:32] unreach=0, hmode=3, pmode=4, hpoll=4, ppoll=4, headway=3, flash=00 ok, [16:53:32] keyid=0, offset=0.349, delay=0.353, dispersion=1.318, jitter=0.020, [16:53:32] xleave=0.086, [16:53:32] filtdelay= 0.41 0.40 0.37 0.37 0.38 0.35 0.36 0.37, [16:53:32] filtoffset= 0.38 0.36 0.36 0.35 0.34 0.35 0.34 0.31, [16:53:32] filtdisp= 0.01 0.28 0.55 0.82 1.09 1.36 1.63 1.90 Local Clock [16:53:38] associd=58884 status=963a conf, reach, sel_sys.peer, 3 events, sys_peer, [16:53:38] srcadr=LOCAL(1), srcport=123, dstadr=127.0.0.1, dstport=123, leap=00, [16:53:38] stratum=14, precision=-18, rootdelay=0.000, rootdisp=10.000, refid=LCL, [16:53:38] reftime=00000000.00000000 Thu, Feb 7 2036 6:28:16.000, [16:53:38] rec=d054ca42.09448a3a Mon, Oct 4 2010 21:48:50.036, reach=377, [16:53:38] unreach=0, hmode=3, pmode=4, hpoll=4, ppoll=4, headway=0, flash=00 ok, [16:53:38] keyid=0, offset=0.000, delay=0.000, dispersion=0.027, jitter=0.004, [16:53:38] filtdelay= 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00, [16:53:38] filtoffset= 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00, [16:53:38] filtdisp= 0.00 0.02 0.03 0.05 0.21 0.23 0.24 0.26 Thanks, Steve _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
