Yes, of course, you're right.

I guess then that it doesn't belong to syslog(3). There is indeed an
API and it does its job pretty well.

I think it therefore belongs to ipfw to do this kind of rate-limiting,
and on a per-rule base, it would be fantastic.

I guess I'll need to take another look at ipfw's source, again. :)

The idea that Bill Gates has appeared like a knight in shining armour to
lead all customers out of a mire of technological chaos neatly ignores
the fact that it was he who, by peddling second-rate technology, led
them into it in the first place. - Douglas Adams (1952-2001)
