[Courses] [courses][security] return RST

[Hamster]

Hello!

While reading through the article on the difference between drop and deny (http://logi.cc/linux/reject_or_deny.html), 
I saw a reference to a programme return-rst.

The return-rst page 
(http://www.bellamy.co.nz/section5.html)
says thats its for 2.2 (ipchains) kernels.

Is there such a thing available for 2.4 (iptables) kernels, and if so, I'd be interested in the hearing the advantages/disadvantages in disguising the fact that you've got a firewall.

Thanks!
