Hi List,

The host that is being attacked, there isn't much you can do about a dDos.

I wonder on the other side what can be done (by pf) to prevent the host
being used as a zombie spawning (spoofed) packets like mad. Anybody a clue?

 Have you read it and understand what it does? The tarball linked to
 contains a userland tool that does most of the work, but at a 
 very high
 price. I guess we could make a port out of that.

 A whole book is a lot of work :) There's probably not a large enough
 market for a traditionally published book (there aren't many paper books
 about OpenBSD in general, even) and for a non-commercial publication,
 time is the limit, as I can't afford that many weeks worth of unpaid
 work.
Writing the book would probarbly stall development.
If it wouldn't stall development newfeatures won't end up in the book.

 Let's put it this way: I can always work on improving the man
 pages and FAQ in smaller chunks,
I think thats sufficient, but I think the initial post was asking for a
step-to-step guide in Building PF firewalling rules.
