[gpsd-users] Feeding chrony from GPSD

[Yakov Shmulevich]

Hi,

I am trying to use chronyd with gpsd for NTP services.

It works perfect then I use the follow definitions in chrony.conf:

# set larger delay to allow the NMEA source to overlap with

# the other sources and avoid the falseticker status

refclock SHM 0 offset 0.183 delay 0.2 refid GPS

refclock SHM 1 refid PPS

So, in this case chronyd synchronized with PPS signal:

address@hidden ~]# /usr/local/bin/chronyc sources

210 Number of sources = 3

MS Name/IP address         Stratum Poll Reach LastRx Last sample

===============================================================================

#- GPS                           0   4   377     3    -73ms[  -73ms] +/-  101ms

#* PPS                           0   4   322    23    +67us[  +45ms] +/-   25us

^? mivzakim.net                  2   6    37    56  -2541us[  +69ms] +/-  248ms

But if, I try to use socket method by follow definitions in chrony.conf:

# set larger delay to allow the NMEA source to overlap with

# the other sources and avoid the falseticker status

refclock SHM 0 offset 0.183 delay 0.2 refid GPS

refclock SOCK /var/run/chrony.ttyUSB1.sock refid PPS

it not synchronized with PPS at all.

What I am doing wrong?

Should I add any definition of the socket path in gpsd running parameters?

Thanks,

Yakov
