Built them and configured them since I had a severe auto crash and the resulting concussion limited how long I could stare at a screen - anyway my question is what are the meanings and acceptable values for the server 127.x.y.z and the various commands. I’ve looked all over NTP docs and searches and I’m unable to find any good info. A pointer to the info is fine or a description of what can go there. The pseudo IP addresses 127.127.y.z are used by ntpd to configure a hardware reference clock. There are quite a few drivers numbered from 0 to n, and the driver number is used for "y".
Each driver may support several clocks with different protocols, and "z" refers to an instance number (usually 0..3) to distinguish between several hardware devices that use the same driver type. For example, 127.127.8.z refers to the generic parse driver which supports a couple of different hardware devices, and is described here: http://doc.ntp.org/current-stable/drivers/driver8.html Note the number "8" in the page URL refers to the "8" in 127.127.8.z.
