I would like to setup a high-precision system time synchronization between two machines using linuxptp.
On the first host:
- the system time is periodically synchronized using NTP using an interface connected to the Internet
- on a second interface (
eno2), I runptp4l -i eno2 -S -P -4 -m
On the second host:
- on the
enp0s31f6interface connected toeno2of the first host, I runptp4l -s -i enp0s31f6 -S -P -4 -m
But, on the second host, ptp4l won't synchronize the system time :

any idea?
