Yeah, that's understood, it was just an example config I used above. I am fairly sure my problem exists regardless of how many external servers are configured (I've reproduced it with two and three). Speaking of magic numbers: aren't even numbers disadvantageous because they can be split by the NTP algorithm into two groups, and then it becomes a gamble to pick which groups to believe? I've heard it said because of that one should pick an odd number of servers, and always wondered if there was some truth to that. On the possibility of my problem being an NTP bug, I presume I have to do some triaging with different NTP versions, to see if maybe newer NTP releases fix this magically (haven't seen a bugfix in the ChangeLog which I could correlate to it). So, unless I get input from someone who can certainly contradict my expectations, I'll assume it's a bug. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
