Re: [Linuxptp-users] question about uds_address in phc2sys, ptp4l

[Ed Branch]

With the -w argument, phc2sys uses this port to communicate with ptp4l to wait until ptp4l is tracking and to get the UTC offset propagated from PTP protocol.

Hi,


That is the uds_address that I give to 'pmc' and I get the correct response.

I was wondering, is uds_address only used for communication with 'pmc'?


Thank you!

I am running two instances of ptp4l on separate interfaces, one is master and one is slave. I have changed their uds_address to be different per iface (/var/run/ptp4leth0 and /var/run/ptp4leth1). If I have 'phc2sys' instance tied to eth0 interface, it's uds_address can be random? Does phc2sys communicate with anyone or is it there just in case I want to grab it's status with 'pmc'?
