For Years ntpd has taken the approach that if we do not "use" a
particular IP address we open-read-drop the packets.
More recently, people have asked for the ability to simply not-open
(ignore) certain IPs and/or interfaces.
To date, I have taken the position that since we have chosen "listen"
and "open-read-drop" as the original behaviors, we should maintain
backward compatibility now that we are allowing "ignore" (as in
There is some Ugliness if we maintain:
"the default if we do not 'listen' is 'drop'"
instead of saying:
"the default if we do not 'listen' is'ignore'".
I have 2 questions for you:
- Do you care?
- If so, how much?
Anybody else have input?
