The Infrared-HOWTO (formerly known as the IR-HOWTO) is an introduction to Linux and infrared devices and how to use the software provided by the Linux/IrDA project. This package uses IrDA(TM) compliant standards. Remote Control (RC) via infrared is not the aim of the project, though this topic is partly treated in the HOWTO.
The PPPOE with Bandwidth Management for OpenBSD Howto is a document which explains how to build an OpenBSD based router for a small flat-sharing community with four residents. The router should manage the available bandwidth fairly between the paying users and their guests. For the residents, it should be possible to use incoming ports for services like Skype or Emule. The howto basically addresses IT professionals with a rough idea of what OpenBSD is about.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
TrinityOS is a step-by-step, example-driven HOWTO on building a very functional Linux box with strong security in mind. TrinityOS is well known for its strong packet firewall ruleset, Chrooted and Split DNS (v9 and v8), secured Sendmail (8.x), Linux PPTP, Serial consoles and Reverse TELNET, DHCPd, SSHd, UPSes, system performance tuning, the automated TrinityOS-Security implementation scripts, and much more.
Wifimap is a Web-based application that graphically documents the organisation and growth of a wireless network community. The map is composed of numerous square cells that are recombined to display the required area. Users can start with just a few cells to cover their area, and can access different areas of the network by scrolling through the cells. New cells can be easily added using a built in editor. Cells can be added at different zoom levels allowing users to zoom in and out of the map. The design makes it very fast, and it can be run on low powered servers. Wireless nodes can be added or edited with a few mouse clicks. Links between the nodes are automatically drawn based on the data entered for each node, and colours are used to represent different wireless protocols.
