Hi, I have a stratum one server running ntpd [EMAIL PROTECTED] with a Garmin GPS 18 LVC as a refclock. I use the shmpps driver from http://time.qnan.org/ . Since this driver only provides the PPS signal, I need to have a few other servers defined in my ntp.conf so that my ntpd knows what time it is.
Here's my concern: the poll interval on those servers is always stuck at the default minpoll (64sec), even though I have not specified so. I would rather not poll those servers at such a rapid rate, but ntpd seems to be doing this on its own, as far as I know. It's been this way since I set up the server, about two months ago. I haven't messed with it, as I assume ntpd knows what it's doing. However, my concern has finally prompted me to ask someone. Here is my ntp.conf (comments removed): restrict default kod nopeer nomodify notrap restrict 127.0.0.1 server 127.127.28.0 minpoll 4 maxpoll 4 prefer fudge 127.127.28.0 refid PPS flag3 1 server tick.ucla.edu iburst server clock.via.net iburst server t1.timegps.net iburst server bigben.cac.washington.edu iburst server clepsydra.dec.com iburst driftfile /var/lib/ntp.drift logfile /var/log/ntp/ntp.log statsdir /var/log/ntp/ statistics loopstats peerstats clockstats filegen loopstats file loopstats type day enable filegen peerstats file peerstats type day enable filegen clockstats file clockstats type day enable keys /etc/ntp/keys trustedkey 1 requestkey 1 controlkey 1 And here is a 'ntpq -p' and 'ntpq -crv' output: saturn:# ntpq -p remote refid st t when poll reach delay offset jitter ========================================================================= *SHM(0) .PPS. 0 l 14 16 377 0.000 0.000 0.001 -tick.ucla.edu .GPS. 1 u 37 64 377 38.910 2.332 1.286 -clock.via.net .GPS. 1 u 51 64 377 34.722 2.470 3.509 +cpe-76-87-109-2 .GPS. 1 u 44 64 377 53.460 0.611 5.654 -bigben.cac.wash .USNO. 1 u 36 64 377 13.590 2.795 2.597 +clepsydra.dec.c .GPS. 1 u 29 64 377 30.161 1.618 1.432 saturn:# ntpq -crv assID=0 status=0964 leap_none, sync_telephone, 6 events, event_peer/strat_chg, version="ntpd [EMAIL PROTECTED] Wed Aug 22 18:27:01 UTC 2007 (1)", processor="i686", system="Linux/2.6.17-5mdv", leap=00, stratum=1, precision=-20, rootdelay=0.000, rootdispersion=0.343, peer=22004, refid=PPS, reftime=cab1a338.1c12986c Fri, Oct 5 2007 23:01:28.109, poll=4, clock=cab1a33e.4d9c88ab Fri, Oct 5 2007 23:01:34.303, state=4, offset=0.000, frequency=-22.221, jitter=0.001, noise=0.001, stability=0.000 Thanks for any help.
