Linvpn is a secure socket layer for pppd. It allows creation of virtual private networks by using an IP routing system between PPP network interfaces. Cryptography is done by libgcrypt's 3DES or blowfish, and Initialization Vector (IV) is changed in each packet transmission. As linvpn works as client and server, and communication is a single TCP connection, it allows creation of secure tunnels even in complex network layouts, when one or both endpoints are behind a firewall or NAT, with or without dynamic IP addresses.
Tabfmt is a command line utility to format tabular data. The program reads lines from one or more files or from standard input, breaks the lines into fields given a set of input field delimiters, and prints a table with constant-width columns to standard output or a specified file. Many options exist to customise the output.
FreePlot is a simple mathematical program that plots 2D functions written in Python. It provides an easy-to-use interface and a powerful graphing mechanism that allows the user to understand what she is doing at all times. FreePlot features out-of-the-box multiplatform support for GNU/Linux, BSD, Win32, and MacOS. Functions can be saved to an image file. An unlimited number of functions can be used on the same cartesian plane. Multiple colors, multiple line styles and marks, and legends are supported.
Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts that can be used separately or in combination. The first part is a small patch against the PHP core that implements a few low-level protections against buffer overflows or format string vulnerabilities. The second part is a powerful PHP extension that implements all the other protections. Suhosin is binary compatible with plain PHP installations.
polyBSD is a "multi"-purpose (hence "poly") framework for building embedded systems based on NetBSD. Essentially, it is a minimal installation of NetBSD 3.0.1 designed to run from a 256MB flash card or USB memory stick. Once the image is written to the target media, a user can simply boot from it and build their own system by using NetBSD's extensive "pkgsrc" collection. The user is only limited by the free space left on the 256MB memory card/stick.
