It is not good practice to use "pool" on 100-1000 internal systems, presumably via NAT, to poll time from internet. Simple advice is: setup 1 NTP server when you are always monitoring, or 2 servers when you cannot always be on watch to fix the one server, and keep them mutually synchronized. That will work OK in a company. Maybe not in the head of a thought experimenter, but that is normally not what companies are after. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
