So we did receive an Announce message (I guess on the general port). > ptp4l: [7770.221] recvmsg failed: No such file or directory But here recvmsg() returns ENOENT. 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.
