Nightwing allows the creation of quickly deployed wireless networks without the need to make complicated configurations. With the implementation of a Mesh technology called B.A.T.M.A.N, Nightwing allows the extension of wireless networks with a simple way of adding devices that works with minimal human intervention. It has public and private connection interfaces, and the ability to filter content using OpenDNS. It is designed with security in mind, and has low hardware requirements.
Gargoyle is an interface for small, widely available routers such as the Linksys WRT54G series and the La Fonera. It provides functionality above and beyond what the default software provides including sophisticated dynamic DNS, quality of service, and bandwidth monitoring tools. The primary goal is to provide a polished interface for these advanced tools that is at least as easy to configure as any existing firmware. This project is based on top of OpenWrt, but unlike other Web interfaces for OpenWrt it places a strong focus an usability and is meant for average users, not just power users.
ferm is a tool to maintain and setup complicated firewall rules. It allows one to reduce the tedious task of carefully inserting rules and chains, thus enabling the firewall administrator to spend more time on developing good rules, and less time on the proper implementation of those rules. These rules will be executed by the preferred kernel interface, such as ipchains and iptables, and in one pass. Firewall rules can also be split into different files and loaded at will.
m0n0wall is an all-in-one firewall software package that is based on FreeBSD. It is geared towards embedded PCs, but it also works on standard PCs. It includes an easy-to-use Web interface like commercial firewall boxes do. PHP is used instead of shell scripts, and the entire system configuration is stored in a single XML-formatted file. There is support for VPN, traffic shaping, captive portal, VLANs, and more.
LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls. More importantly, LFT implements numerous other features, including TCP, UDP, or ICMP-based traces, AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more. LFT also distinguishes between layer-4 protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.
Coyote Linux is a mini distribution designed for setting up network utility services such as Internet connection sharing, firewalling, or wireless access points. The goal is to make it as quick and easy as possible to set up a Linux system with only a minimal amount of Linux knowledge.
