Thank you both for responding so quickly! David, I tried the patch you recommended and but ended up getting this result: ptp4l[4756130.278]: port 1: INITIALIZING to LISTENING on INITIALIZE ptp4l[4756130.278]: port 0: INITIALIZING to LISTENING on INITIALIZE ptp4l[4756130.278]: port 1: link up ptp4l[4756130.952]: port 1: bad message ptp4l[4756131.951]: port 1: new foreign master 000cec.fffe.0d013a-1 ptp4l[4756131.952]: port 1: bad message ptp4l[4756132.952]: port 1: bad message ptp4l[4756133.952]: port 1: bad message ptp4l[4756134.952]: port 1: bad message ptp4l[4756135.951]: selected best master clock 000cec.fffe.0d013a ptp4l[4756135.951]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE ptp4l[4756135.952]: port 1: bad message
Followed by continuous bad messages after that. I checked the tcpdump and none of the UDP messages I saw had a zero payload, so I'm not sure what the bad messages are. I also tried running ptp4l v2.0 and I got a slightly different error message: ptp4l: [8549.759] selected /dev/ptp0 as PTP clock ptp4l: [8549.761] port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l: [8549.761] port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l: [8550.221] port 1: new foreign master 000cec.fffe.0d013a-1 ptp4l: [8550.221] recvmsg failed: No such device or address ptp4l: [8550.222] port 1: recv message failed ptp4l: [8550.222] port 1: LISTENING to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED) ... I'm not sure if it's relevant but I have been able to use ptpd2 with both slave systems and the Versasync clock with the same network setup.

Strange. That error isn't listed on the man page. I briefly scanned the kernel stack, and there are indeed a few cases where ENOENT can be returned, but I didn't see anything that could apply in this case. Could this possibly be due to a firewall? > I know the recvmsg failed error has something to do with the ptp4l > socket but I'm not sure how to go about fixing it.
