Bluelog is a Bluetooth site survey tool, designed to tell you how many discoverable devices there are in an area as quickly as possible. Bluelog differs from most Bluetooth scanners in that it prioritizes speed of reporting over anything else (i.e. it doesn't spend time trying to pull detailed data from a device) and doesn't require any user intervention to function. As the name implies, its primary function is to log discovered devices to file rather than to be used interactively. Bluelog could run on a system unattended for long periods of time to collect data. In addition to basic scanning, Bluelog also has a unique feature called "Bluelog Live", which puts results in a constantly updating Web page which you can serve with your HTTP daemon of choice.
linux_ics is designed to make the process of sharing an Internet connection from a Linux computer easier for the average user. It handles configuring the interfaces, setting up NAT, and optionally running a DHCP server. In addition to Ethernet, linux_ics can also share an Internet connection over a WiFi interface in either ad-hoc or master mode.
Spectra is a simple tool designed to aid in evaluating the quality of random numbers generated by TRNGs and PRNGs. It does this by counting the occurrences of characters within a given input file to help detect perceived bias, and then visualizes the data as colored (or black and white) pixels in an image file to aid in detection of repeating patterns. As the human mind is exceptionally good at picking up on patterns that might otherwise be difficult to detect mathematically, Spectra allows the user to rapidly make a determination on the repeatability of numbers generated from the suspect RNG.
Bluefog is a tool that can generate an essentially unlimited number of phantom Bluetooth devices. It can be used to test Bluetooth scanning and monitoring systems, make it more difficult for attackers to lock onto your devices, or otherwise complicate the normal operation of Bluetooth devices. Technically, Bluefog can work with just one Bluetooth adapter, but it works much better when you connect multiple adapters. Up to four radios are currently supported simultaneously.
