We have run into a time sync appliance (that uses GPS signals to set the time) that doesn’t speak (not willingly, at least) NTP v2. It will speak NTP v4. Alas, check_ntp_peer does not seem to speak NTP v4, but only v2. check_ntp (which claims that it is deprecated) does speak v4, as does check_ntp_time, but check_ntp_time is meant for comparing the local clock’s offset.
So … any plans to update check_ntp_peer to do its thing using NTP v4? Eric Stewart Network Engineer University of South Florida – Information Technology 4202 E.
