Did you mean to say "replies on the same socket?" To a networking guy "socket" is distinct from interface (eg NIC) and from the first hop routing decision to be made by the stack. Soooo, if NTP is replying on the same socket, and it _isn't_ the/a wildcard socket, then the source IP's should already be correct and the mystery would seem to deepen. Might be a good idea for the OP to get a system call trace of NTP, preferably including the creation and binding of the sockets and then the receipt and sending of a response. rick jones -- oxymoron n, Hummer H2 with California Save Our Coasts and Oceans plates these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
