Compare the above two client addresses in the output of
"ntpdc -nc monlist 132.246.168.2" :
remote address port local address count m ver drop last first
69.63.219.2 353 132.246.168.2 99 3 3 0 18 6354
69.156.105.192 2605 132.246.168.2 11 3 4 0 294 6309
Then examine this piece of code in ntp-4.1.0/ntpd/ntp_proto.c receive() :
if (!(SRCPORT(&rbufp->recv_srcadr) == NTP_PORT ||
SRCPORT(&rbufp->recv_srcadr) >= IPPORT_RESERVED)) {
sys_badlength++;
return; /* invalid port */
}
QED. Time to upgrade to a later version ...
