"The Internet today is a jungle full of predators. Some of these predators are trying to crack your machine others are just looking for a machine to crack. By using the firewalling tools built into the Linux kernel it is possible to make a desktop machine virtually disappear from the crackers view."
"In this article I will describe how to hide a machine running Linux that uses PPP over a modem to connect to the Internet. I will use ipchains and the firewalling built into the Linux kernel to protect the services that are running on this machine from connections across the PPP interface."
"For this example, I will use a Debian system with a 2.2.15 Linux kernel on a Debian system. You should note that the firewalling code in the 2.4 Kernel has undergone a rewrite, but that the examples in this article will still work by loading the ipchains compatibility module."
