Starting on about 6/14/16 at around 0400 local time (Central Daylight Time US UTC-6) all 5 of our time servers here can't be reached by the Status polling servers apparently. Yes if I put up tcpdump on the Linux hosts and do a packet capture on port 123 I can see traffic from many other hosts coming into all 5 of the systems here and no one is reporting any outages (including where I'm employed that used them and monitors them - they were unreachable we'd have pages going off within 5-10 minutes).
There is no firewalling that would block by IP or port for port 123 and nothing has changed here for set up at that time to cause them to suddenly drop out. Is there some way I can see what the Pool Status polling is looking like from the NTP Pool end to get more of a clue as to why this has suddenly started to fail? I've sent email to Ask but haven't yet received a reply. George _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
