[Linuxptp-users] ptp4l sync and connection

[Bassam A. <als...@gm...>]

Hi everyone, 

I have two Linux machine that are directly connected via Ethernet cable 
and both machines have i210 NIC. Both sides run ptp4l.

I tried linuxptp 1.6 and 1.5 with the same result (as it seem something 
wrong on my end). Attached the result I see from both machines. They 
seem to be synced but there is no offset updates as the slave stuck on 
the state "LISTENING to UNCALIBRATED on RS_SLAVE". Thoughts??

Looks like packets are not getting through.  Disable your firewall
rules and then confirm the PTP traffic with wireshark or tcpdump.

Thanks,
