In NTP/PPS mode,
sfptpd will get time-of-day from NTP, then use
the 1PPS signal to closely synchronize the adapter clock. All other clocks, including
the system clock, are synchronized to the adapter clock.
sfptpdto control the local NTP client.
For this mode, use the default pps_slave.cfg file:
- from the tarball package:
cd <install_dir> ./sfptpd -i <interface> -f config/pps_slave.cfg
- from the binary RPM package:
cd /usr/share/doc/packages/sfptpd/ sfptpd -i <interface> -f config/pps_slave.cfg
<interface> is the identifier of the timestamping port on the adapter.
