FW1-Loggrabber is a simple LEA (Log Export API) client for Checkpoint Firewall-1. It was developed to access Firewall-1 Logfiles from commandline from any host in the network. Without an LEA client you can only access logs with graphical Checkpoint Tools or via commandline directly on the Firewall-1 machine. The primary goal was to automate reports of FW-1 logs with LIRE.
Fair NAT is a script for configuring NAT on dedicated Linux routers. It's designed to be highly customizable and therefore well documented. A configuration file lets you specify which clients on your LAN should be allowed to use the router, which ports are to be forwarded to which client, and much more. It uses the kernel's Traffic Shaping capabilities to share bandwidth in a fair manner among users. Some kernel patches are recommended for better performance. Experimental support for peer-to-peer traffic detection is available.
The Falcon Project (Free Application-Level CONnection kit) is an open firewall project with the intention of developing a free, secure and OS-independent firewall system. Falcon consists of three major modules: Falcons's own proxies (written in Perl); 3rd-party proxies (squid / qmail / BIND8), each modified for chroot environment; and general concepts for OS hardening, chrooting etc.
Fd Linux is a mini floppy distribution of Linux set to fit on 1 floppy disk (kernel and root fs are combined). The sole purpose of this floppy distribution is to provide new Linux users with low-end machines (such as a 386) a very useful set of networking related binaries that can be easily accessed at any time, and which can be used in almost any networked environment (libraries, colleges, offices, small home LANs, dorm rooms, etc.).
