Point. Though not all DDOSes are created equal. The simple packet
flood is, as likely as not, from forged addresses. But I've also seen
DDOSes which make repeated HTTP GET requests. That's tough to do
without control of the source address.


Now it would be trivial to setup syslog and sshd to give only the sessions
that complete the handshake, however I'm also not sure how responsive some
of the abuse contacts may be. I'll keep my restrictive network settings for
the time being.

That's the main problem: you can generate the report but if it's about
some doofus in Dubai what are the odds of it doing any good?
