Broadcast clients require authentication by default. So, yes, this is the expected behavior. If the client does not require an authenticated server, you can disable authentication. The reason is that ANYBODY with the proper software can broadcast NTP packets on your network. Those packets may have the correct time or they may not! If the time is not correct youf clients may be off by anything from seconds to years! _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
