The "noselect" explains why your NMEA clock isn't being used. Remove that and see how it goes. Also I notice you're not using fudge flag1 1 to enable PPSAPI -- if you aren't using serialpps.sys, that's appropriate, but the highest quality PPS timestamps require that driver and flag1 1. > > # GPS PPS > #server 127.127.22.0 minpoll 4 maxpoll 4 prefer > #fudge 127.127.22.0 flag3 1 > > #Inhouse reference > server 192.168.5.8 iburst maxpoll 9 > > logconfig =all I'd have used =allall, but I can't swear =all won't do the same. You might check for any warnings at startup suggesting it's not. > driftfile /etc/ntp/drift > enable stats > statsdir /var/ntp/stats > statistics loopstats peerstats clockstats Cheers, Dave Hart _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
