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.
eCos (Embedded Configurable OS) is an open source, configurable, portable, and royalty-free embedded Real Time Operating System. It is written in C++, provides all the usual OS things. You configure the OS so that the parts you don't need aren't loaded to the embedded system. eCos is released under a modified GPL that allows for its use in embedded systems without having to GPL the embedded application.
Pocket Linux is an almost minimal, one floppy linux system designed to quickly convert PC workstation into secure linux-based workstation using ssh to connect to remote host (other networking clients are also supported). It supports bootp for determining host IP and other network parameters (there's also manual configuration possible, but bootp is recommended). In addition to workstations equipped with a network card (ethernet or arcnet), you can also use Pocket Linux on a PC equipped with a modem. Modem is automatically detected and then PPP connection is made.
QuickSwitch lets you switch network profiles on the fly (IP address, DNS, routes, NFS shares, etc.). There is a command-line configuration mode by which you can change your entire network setting in one line (including DNS and routing table). It is highly configurable, supports DHCP/BOOTP/NIS/NFS/etc., and also includes a curses-based GUI which you can use as a profile selector on startup.
SmoothWall Express is a network firewall, designed with home and small business users in mind. It is based upon a security-hardened subset of the GNU/Linux operating system and is completely free to use, download, and distribute. SmoothWall Express offers facilities and features normally only seen in expensive commercial offerings.
WANPIPE S-series is a family of intelligent multi-protocol WAN and ADSL adapters that support data transfer rates up to 8Mbps. All WAN protocols supported by WANPIPE are implemented in firmware and run on the card. An advantage of an intelligent adapter is that it offloads the system CPU and improves stability. By adding a Sangoma WAN/ADSL component to the Linux kernel, one can create a powerful multi-T1/ADSL router/firewall with proven reliability of Linux. Sangoma S-series cards support an optional on board T1/E1 CSU/DSU that eliminates all external components of a traditional routing solution: i.e. T1/E1 line can be directly connected to the card. WANPIPE supports the following protocols, ATM, ADSL, Frame Relay, PPP, MULTILINK PPP, CHDLC, X25(API), BitStreaming (API), BiSync(API), and SDLC(API). Furthermore, WANPIPE supports custom API development such as: Credit card verification, Voice-over IP, Satellite Comm. All device drivers are part of the standard Linux Kernel distribution.
Devil-Linux is a special secure Linux distribution which is used for firewalls, routers, gateways, and servers. The goal of Devil-Linux is to have a small, customizable, and secure Linux system. Configuration is saved on a floppy disk or USB stick, and it has several optional packages. Devil-Linux boots from CD, but can be stored on CF cards or USB sticks.
LooperNG is an intelligent event routing daemon. Primarily used for Network Management, this application can be used to accomplish a variety of tasks related to logging and alerting such as trap forwarding/exploding, event enrichment, converting event formats (syslog->SNMP, SNMP->flatfile, syslog->Netcool), etc. It uses a system of input and output modules to interface with the event sources/sinks and a "rules file" to control the flow of the events.
The Objex Project (like the GNU Project) aims to develop a complete operating system composed of free and open source software. In contrast to the GNU Project, it aims to build a modern system that brings together all the recent advances in computer science, instead of a Unix-like system. "A complete system" means that it will include the kernel, a full suite of developers tools, user utilities, and a graphical user interface. It is based on OSKit, a framework and a set of utilities, drivers, and program code intended for operating system creation.
SoL (Server optimized Linux) is a Linux distribution completely independent from other Linux distributions. It was built from the original source packages and is optimized for heavy-duty server work. It contains all common server applications, and features XML boot and script technology that makes it easy to configure and make the server work.
