I guess I was under the impression that ntpdate snagged it's info from
ntp servers generally running on port 123. I just assumed it would
return on the same port. Guess that is a wrong assumption.
There is the "-u" option for ntpdate which might be useful -
-u Direct ntpdate to use an unprivileged port or outÂ
going packets. This is most useful when behind a
firewall that blocks incoming traffic to privileged
ports, and you want to synchronise with hosts
beyond the firewall. Note that the -d option always
uses unprivileged ports.
