Hi Richard,
When I tried to implement ptp4l service, I got error massage as below. Oct 7 04:20:27 localhost ptp4l[17885]: [242799.030] port 1: FAULTY to LISTENING on INIT_COMPLETE Oct 7 04:20:34 localhost ptp4l[17885]: [242806.924] port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES Oct 7 04:20:34 localhost ptp4l[17885]: [242806.925] selected local clock 1402ec.fffe.04f911 as best master Oct 7 04:20:34 localhost ptp4l[17885]: [242806.925] assuming the grand master role Oct 7 04:20:34 localhost ptp4l[17885]: [242806.926] send failed: 13 Permission denied Oct 7 04:20:34 localhost ptp4l[17885]: [242806.926] port 1: send announce failed Oct 7 04:20:34 localhost ptp4l[17885]: [242806.926] port 1: MASTER to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED) I have no idea what is really going on. How to debug this. I have given all the permission to relevant files. Or is this hardware fault of my network card ? ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ [root@localhost ~]# systemctl status ptp4l ● ptp4l.service - Precision Time Protocol (PTP) service Loaded: loaded (/usr/lib/systemd/system/ptp4l.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2019-10-07 04:42:12 UTC; 14s ago Main PID: 2342 (ptp4l) Tasks: 1 (limit: 26213) Memory: 492.0K CGroup: /system.slice/ptp4l.service └─2342 /usr/sbin/ptp4l -f /etc/ptp4l.conf -i eno2 Best Regards, Ganganath
