I am not sure what you are saying. Are you saying that 4 servers allow you to have a failed server and then outvote a falseticker. I don't think that is true. And it definitely takes three servers to outvote one falseticker in some cases. NTP deals in intervals, and it takes two servers to define one interval, and then one more to make that interval outvote all the others possible intervals. So, three servers will always outvote a single falseticker, but two will not always outvote a single falseticker. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
