quoth the Dave Jones:
 TARPIT

Just a caveat: Keep in mind that if a bad guy figures out you are using 
TARPIT, the very nature of it (ie: persistant connections) opens your box to 
a severe DOS vulnerability, especially if said bad guy has a bot-net at his 
disposal.

If you know what you are doing, fair enough, but do keep this in mind if you 
intend to use TARPIT on an outward facing box.

Hi Andrew,

Thank you for the tip about TARPIT, the problem is now solved.

To complete the fix I downloaded patch-o-matic-ng and the iptables
source from netfilter.org:

cd /usr/src
svn co https://svn.netfilter.org/netfilter/trunk/patch-o-matic-ng
svn co https://svn.netfilter.org/netfilter/trunk/iptables

The documentation on using cvs on netfilter.org is outdated, they've
converted to subversion and cvs is no longer available there.

cd /usr/src/patch-o-matic-ng
./runme extra

Allowed me to select the new iptables targets I wanted.

cd /usr/src/linux
make menuconfig  make  make modules_install  make install

I added the extensions USE flag to my /etc/make.conf, then reran the
iptables emerge.

It's all working fine now.

Thanks to both you and Bryce for the help you gave!

Cheers, Dave

 I was reading about the TARPIT target in the man iptables documentation,
 and thought I'd like to give it a try.  Unfortunately though, it seems
 not to be supported in the 2.6.15-1 Gentoo kernel.

 Has anyone used the TARPIT target, or know of a way to get it into the
 current kernel?  Any experience with this target or 'gotchas' about it?

[gentoo-user] TARPIT iptables target

Hi,

I was reading about the TARPIT target in the man iptables documentation,
and thought I'd like to give it a try.  Unfortunately though, it seems
not to be supported in the 2.6.15-1 Gentoo kernel.

Has anyone used the TARPIT target, or know of a way to get it into the
current kernel?  Any experience with this target or 'gotchas' about it?

Cheers, Dave
