Has anyone been successful at using the TARPIT target in iptables under

I don't have any CentOS4 box handy to check it out, but it seems like the
kernel module is missing. Netfilter has two component, userspace (in
/lib/iptables) and kernel (in your kernel's directory under /lib/modules).
The userspace as packaged by Red Hat often has many more modules than
actually supported by kernel.
What Alex has described seems to be the case. I exploded the source from
the centosplus kernel rpm and discovered that the source for the TARPIT
target does not exist. Does anyone know why Red Hat includes iptables
userspace modules without the corresponding kernel modules? Is this an
indication of future inclusion? It appears that building support for
iptables modules is a bit trickier that building standard kernel modules.
The best writeup I have found thus far is at:
<http://www.centos.org/modules/newbb/viewtopic.php?topic_id=4053>
It seems to me that it would be quite powerful to have iptables string
match and TARPIT target support. Are there any plans to include any of
the extra iptables functionality in the centosplus kernel?
If anyone has any information on building iptables kernel modules,
particularly those included in patch-o-matic-ng to work with the
centosplus (or any other) kernel without compiling an entire kernel,
please let me know.
Thanks,
Barry
