Re: [Linuxptp-users] Should Linux PTP syn the clock used by date between PCs?

[Gil G. <Gil...@ha...>]

So if it is not best practice, how else can I sync the system clock on the master and the slaves?
I would like all system clocks  on the Lan to be synced to the master hardware clock on the master NIC.

It is not best practice to use the system for a PTP master.  However, you *can* do this if you really, truly want to.  On the master, you need to repeat the '-r' phc2sys option in order to confirm the unusual configuration.

Master:
	ptp4l -i eth0
	phc2sys -a -r -r

Slave:
	ptp4l -i eth0 -s
	phc2sys -a -r

That should work better for you.

Thanks,
Richard
