I have seen a similar description in many website and even a couple books. The text in this question was taken from "http:// networking.ringofsaturn.com/Protocols/ntp.php".
While I'm at it I'll describe my setup as well. I have two equivalent machines (A & B) which I want to be tightly time synchronized with each other. Both machines will have the same reliable external servers configured in the NTP config file. But I want to be covered in the case that the machines lose connectivity to the external NTP servers. This is what I understand after looking at all the responses: - My assumption that setting Machines A & B as NTP peers still seems to be a good setup. - Losing connectivity to the reliable time sources from all peers is called Orphan Mode - I'll call the case when the time sources are available as Normal Mode - In Normal Mode the machines will set their time based on a logical weighted average of its external source and its peer. - In orphaned mode the two machines will pick one of the machines as server based on some mysterious NTP random number. Do the assumptions above sound correct? In orphan mode say if machine A is chosen as the NTP master would A sync to itself and not B? Or do both A and B become Master and Slave of each other and use a weighted average of the local machine an peer? Is peering the best option in my case? Thanks for all your help! _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
