userspace tarpit

...

Hello!

I completed a simple userspace tarpit script:

http://www.radlinux.org/connexion/browser/branches/0.4.4/lib/cxnet

It is not a production solution, but an example of cxnet usage. Whilst not as 
fast as libnfnetlink and kernel netfilter, cxnet is extremely simple and can 
be used for rapid net-apps development or in GNU/Linux network studies (e.g., 
for educational purposes).

Cxnet isn't a complete implementation of netlink and tcp/ip :) Only some 
features are implemented: full rtnetlink and netfilter support, as well as 
udp and icmp primitives, are in the todo.
