It would be also good to know what GPS receiver is it. Maybe it doesn't have PPS or it is not working? gpsd prints some useful messages in the debug mode. E.g. gpsd -n -N /dev/ttyS0 -D 9 2>&1 | grep PPS Anyway, there are several options when configuring chrony to use GPS with gpsd. I think the best options are: A) refclock SHM 1 B) refclock SOCK /var/run/chrony.ttyS0.sock C) refclock SHM 0 refid NMEA noselect refclock PPS /dev/pps0 lock NMEA Only one should be used at a time. B requires chronyd to be started before gpsd. C requires gpsd (or ldattach) to be started before chronyd. In A the order doesn't matter. -- Miroslav Lichvar -- To unsubscribe email chrony-users-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
