you should get an ICMP port unreachable if there is no UDP service listening.
i haven't looked at nagios, but i wonder if it's not trying to use NTP
"mode 6" control messages to get more status information out of the
daemon. openntpd doesn't support these queries...

or "rdate -pnv <host>". quite some time ago i added a check to make
rdate bail out if the server is unsync'd.

if ((data.status & STATUS_ALARM) == STATUS_ALARM) {
warnx("Ignoring NTP server with alarm flag set");
return (-1);
}
