I understand that clients in one DC will use both the NTP servers in the same DC and in the other one. Is my understanding correct?

I believe you can mitigate this in two ways: 1) have three servers in each DC and have the clients in the remote offices connect to all the six of them -- if you lose connectivity to one DC you will still run on more than two servers 2) use the configuration you mentioned but have the clients in the remote offices "prefer" one of the servers from the DC that serves two. This way you'll make ntpd "trust" (so to say) more one of the two and partially mitigate the bad side effects of having two. my 0.02 Ciao! -- bronto _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
