NTP is only suitable when there is a single standard of time. That means that one of these servers must use the other as its timing source; they can't free run individually, unless they are both synchronised from some common time source, outside of NTP. Also, ntpd doesn't synchronise to just one of the available servers; it synchronises to a weighted average of the time from all the valid servers (see clock_combine in ntp_proto.c), so normal clients will synchronize to a mix of the times on the two servers, assuming they are both up and have compatible times. If the times are not compatible, there is a risk that both will get rejected - I'm not sure whether ntpd will throw out its last server as a falseticker, or not. What you probably need to do is to use orphan mode between server A and B and accept that the clients will use a mixed time from both servers. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
