[Linuxptp-users] clock_servo ntpshm question

[Marco D. (SIDN) <mar...@si...>]

Hi,

So, I decided to configure 'clock_servo ntpshm' to use LinuxPTP as a 
'refclock' for an NTP-daemon on a server with software time stamping.

And it appeared to worked well, until I looked a bit closer.

I noticed that with 'ntpshm' the servo state remains 's0' and the port 
state remains UNCALIBRATED.

By choosing 'linreg' and enable the 'local' refclock in NTP I got it 
working as expected, but I find this a suboptimal solution.

So, I would like to understand why ptp4l won't move to 's2' / SLAVE 
status in servo_clock ntpshm mode.

Anyone?

Thanks!
