I don't think you want to both broadcast AND have the clients poll. One or the other but not both! When a client is using broadcast mode, it initializes by exchanging packets with the broadcast server to determine the typical value of delay. It then uses this figure to correct subequent broadcast packets. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
