Netfilter Module Help

Lloyd,

The "man libipq" example almost works, if you haven't seen 
that yet.  There is a sample program in "man libipq" help page.

http://www.prismnet.com/~aef 

Hogwash for IPTables is there.

Inside hogwash_iptables.tar.gz is "hogwash.c"

Hogwash.c is actually very simple relative to Netlink, if you 
go get that and look at it, and compare it to your own code,
you should get up and running quick.  It really is simple if 
you ignore all the extraneous code in there.

Search for ipq_set_verdict, see that loop.

I have bugged these guys here a bunch getting up and running right
so to return the favor I will help you get started.

Try that, and if you get stuck, send me what you have.

Also, check to make sure you got the source to, and BUILT 
iptables-1.2.2.   You need to do something like make install-devel.

Your build needs to linclude a library -lipq.

etc.,

I didn't start having success until I built kernel 2.4.7 - FYI
