ntpd connect gpsd shared memory driver
|
| |
Based on poor luck with ntpd/pps, I'm trying to have ntpd use the shared
memory driver provided by gpsd. Do I need to give a special flag to
configure for ntp to tell it to build in support for the shared memory
driver?
Using this for my ntp.conf

ntp-b.boulder.nist.gov not synchronized
|
| |
Since about 1800 Eastern time (US) on 10Jun, ntp-a.boulder.nist.gov is sending "clock unsynchronized". This is one of two NIST-supported, _authenticated_, timeservers (the other is ntp-b.nist.gov).
We are regulatorily required to confirm twice daily that our system's time (derived from GPS) is within 1 second of "official" US Gov't time... more »

Hello
I would like to get some points of view before starting to write some code.
I am trying run an electronic board I designed.
A super stable OXCO generates pulse per second.
I don't have any absolute reference time. The pulse has a constant but unpredictable phase due to the state of the electronics a power up.... more »

NTP Server Synchronizing with the incorrect NTP server
|
| |
Problem:
I configured my NTP server in Linux to use the US Pool of NTP Servers in /etc/ntp.conf. I restarted the NTP service many times and the actual server many times, but it was not using the pool. I was verifying this by using the ntpq -p command. It was using a time server it picked up via DHCP when it was plugged into a completely different network. I had no idea where it was getting this information.... more »

Behaved ... Limited ... KODed
|

Hello,
I thought I understood how a client's rate control indicator goes from being
well behaved (.) to limited (L) to KoD (K) but after trying to explain this to
someone today it is obvious that I do not. A server running the most recent dev
release (or post whatever version changed minimum to seconds instead of 2**n)... more »
