Re: [gpsd-users] problem with Stratum-1-Microserver HOWTO

[Charles Muggen]

I don't know what happened...

on the new raspi 3, I ran some commands. as root.
(I still need help with this sudo vs su thing. I don't understand.)

I ran:
systemctl stop ntp
./gpsd/gpsd /dev/gpsd0
./ntpsec/build/main/ntpd/ntpd -g -c ntp.conf

then I ran:
ntpq -p

     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
 SHM(1)          .PPS.            0 l    -   64    0    0.000    0.000   0.002
*SHM(0)          .GPS.            0 l   40   64   37    0.000   43.706  52.221
 us.pool.ntp.org .POOL.          16 p    -  512    0    0.000    0.000   0.002

then I ran ntpshmmon:
it's ticking off lines.
I tried to copy the results to a text file.

I tried every combination of redirection.
ntpshmmon > file.txt
ntpshmmon 2> file.txt
ntpshmmon &> file.txt
ntpshmmon | tee file.txt
ntpshmmon |& file.txt
nothing works.


I ran ppstest;
ppstest /dev/pps0
that's showing positive results.

what else can I check?
is there a utility that shows the system time being micro-adjusted?
