FireHOL a simple yet powerful way to configure stateful iptables firewalls. It can be used for almost any purpose, including control of any number of internal/external/virtual interfaces, control of any combination of routed traffic, setting up DMZ routers and servers, and all kinds of NAT. It provides strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, whitelists, and more. Its goal is to be completely abstracted and powerful but also easy to use, audit, and understand.

LinuxConsole is a live and modular Linux distribution that can be started from CD/DVD, hard disk, floppy disk, USB disk, or network card (PXE). The use of "console" in the title doesn't mean that it is started in "console" mode, but is meant to symbolize the simplicity of using it. This distribution is as simple to use as a game console: you can start applications without installing them. It is modular: there is a common base (device detection, GUI) and optional modules for multimedia, communication, and servers. The goal is having a very fast startup (less than 20 seconds), very good hardware detection, and many applications available (not just games).
GFSGL is a program that makes running and installing games (and other programs) easy under Linux and other Unix-like operating systems. It can autodetect installers in your CD-ROM drives (both native to Linux and those run through Wine/Cedega). GFSGL can launch many different games including native, Wine, and ScummVM games. It has both a console and a graphical interface.
