If the orphan stratum is high enough, e.g. 10, between the ophan's stratum, the orphan's dispersion, the clients reach count for the orphan, and the clients checking other servers, they would ignore the orphan, till it got its act together. > How do you deal with is?

Have the clients look at more than server? e.g. # Start ntpd with -g, the -g will prevent a panic stop if the time needs to be stepped 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 YOUR_MD5_KEY trustedkey 123 manycastserver 224.0.1.1 manycastclient 224.0.1.1 key 123 preempt multicastclient 224.0.1.1 key 123 preempt broadcastclient # server ###.###.###.### iburst key 123 # server ntp.example.net iburst preempt # pool pool.ntp.org preempt # Won't hurt anything if the internet can't be reached > Switching off tos orphan doesn't fit my requirements.. -- 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
