Try orphan mode with manycast instead? That way if the Corp LAN S1/S2 NTP servers go down, they should at least stick together as a time island, and pickup the LAN S1/S2(s) when they are accessible again. # Start ntpd with -g, the -g will prevent a panic stop if the time needs to be steped when started # ntp.conf for ALL (Clients and/or Servers) tos cohort 1 orphan 11 restrict default limited kod nomodify notrap restrict 127.0.0.1 restrict source nomodify keys "/etc/ntp.keys" # e.g. contains: 123 M LAN_MD5_KEY , 321 M Corp_MD5_KEY , ... trustedkey 123 321 manycastserver 224.0.1.1 manycastclient 224.0.1.1 key 123 preempt multicastclient 224.0.1.1 key 123 preempt broadcastclient # Corp LAN S1/S2(s) server tid.tanso.net key 123 iburst prefer preempt server klokke.tanso.net key 123 iburst prefer preempt # Add Below, to Corp LAN S1/S2 servers (e.g. tid.tanso.net & klokke.tanso.net) # Corp LAN S1/S2(s) peer tid.tanso.net key 123 iburst prefer preempt peer klokke.tanso.net key 123 iburst prefer preempt # Corp Remote S1(s) server clock.corp.example.com key 321 preempt server tick.sister.example.com key 321 preempt server tock.brother.example.com key 321 preempt # Other servers with permission, following access restrictions # <http://support.ntp.org/bin/view/Servers/RulesOfEngagement> server time.la4rha.net iburst preempt server ntp-public.uit.no iburst preempt server fartein.ifi.uio.no iburst preempt # <http://www.pool.ntp.org/vendors.html> (Your vendor zone, OS vendor, ...) pool 0.tanso.pool.ntp.org iburst preempt pool 0.rhel.pool.ntp.org iburst preempt pool 0.vmware.pool.ntp.org iburst preempt # <http://www.pool.ntp.org/zone/@> (Regional pool servers) pool no.pool.ntp.org iburst preempt pool europe.pool.ntp.org -- E-Mail Sent to this address <blackl...@anitech-systems.com> will be added to the BlackLists. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
