What am I failing to understand here? The poll values reported in >ntpq -p are 64, 64 and 1024 - as expected. You are forgetting that ntp throws away 7/8 of the stuff it collects. (This is in an attempt to counter round trip biases). Thus you would expect to have 8 times the max poll interval between loopstats. (it is random so it is not always exactly 8 times sometimes less, but never more, but it averages out to pretty close to 8 times.) >Thanks, >David _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
