Computer Breaker project is a network testing tool for services vulnerabilities.

Computer Breaker is a network testing tool that allows networking administrators to test if a computer is vulnerable to malicious attacks.

Using the Nessus scanner, computer-breaker scans the remote host and automatically exploits its vulnerabilities.

mediaCenter is a startup center for multimedia computers that can be configured through one configuration file. mediaCenter project can be controlled by keyboard or with a remote control.

This program is intended to be a small launcherProgram for simple multimedia stations. The configuration is done in ${HOME}/.mediacenter/config.xml. If you start without any parametrization, the default one is taken from ${PREFIX}/mediaCenter/config.xml. Note that this may result in missing button images or wrong execution paths.

Open Computer Vision Library is a collection of algorithms and sample code for various computer vision problems. The library is compatible with IPL (Intel Image Processing Library) and utilizes Intel Integrated Performance Primitives for better performance.

Philosophy

Aid commercial uses of computer vision in human-computer interface, robotics, monitoring, biometrics and security by providing a free and open infrastructure where the distributed efforts of the vision community can be consolidated and performance optimized.

COMSERV is a program that allows you to talk to a network terminal server such as a Xyplex MAXserver 1600.
The handy thing about this program is that the client side of the connection does not need to know anything about how to talk to the terminal server. COMSERV handles the connection details. Thus, you can use existing programs like tip to talk to devices attached to your network terminal server without any modification.
Also, you can use COMSERV to turn your Unix computer itself into a terminal server and serve up its own local serial ports over the network for remote systems to access. This is handy if you have several systems lying around and you want to utilize devices attached to their serial ports.
My primary motivation for writing this program was to expand the I/O capabilities of my FreeBSD home computer. I have many serial devices that I want to connect to my PC which include my modem, Palm Pilot, GPS, various micro-controllers, my EEPROM programmer, and other computers and printers. But with only two serial ports on my PC, I became annoyed at having to reach around the back of my computer and swap cables every time I wanted to plug in a different device. [I think all inventions are the product of the laziness of the inventor :-)] So I searched eBay and found a couple of these Xyplex terminal servers that looked promising, I bid on them, got them, and began hacking.
The only problem with using this type of device for serial expansion, is that if you use a program like tip on Unix (tip is a very basic but functional program to connect directly to a serial port), it expects to be able to open the serial port by opening a /dev/xyz device file that corresponds to a real serial device. The Xyplex, on the other hand, communicates to the Unix system via an ethernet network. In order to talk to one of the serial ports on the Xyplex, you need to establish a TCP/IP connection between your Unix computer and the Xyplex device at a particular TCP port. The TCP port you connect to determines which Xyplex serial port you connect to. For the Xyplex 1600, serial port 1 is TCP port 2100, serial port 2, is TCP port 2200 and so on.
Unfortuneately, tip, and programs like it, have no idea how to establish a TCP/IP connection to the Xyplex in order to transfer data to and from a serial device connected to the Xyplex.
This is what COMSERV does. COMSERV creates a set of pseudo-tty device files that are palatable to tip and other programs. COMSERV opens the master side of the pseudo terminal and the client program (tip in this case) opens the slave side. Data written on the slave endpoint comes out on the master endpoint and vice-versa. This mechanism establishes a connection between the client program and COMSERV. COMSERV then uses TCP/IP to establish a connection to the network terminal server.
Thus, data originating from the client program is written to the slave tty where is read by COMSERV. COMSERV then writes the data to the network socket to the Xyplex, which then passes it on to the designated serial port. Data originating from the serial device attached to the Xyplex takes the reverse path.
Only one instance of COMSERV is required to be running on your system to handle all of your network terminal servers (it can handle as many terminal servers and ports as the speed and resources of your system allows). COMSERV is designed to handle many connections in this fashion, and does so by multiplexing between them using asynchronous device and socket I/O.
While I wrote COMSERV to talk to a Xyplex MAXserver 1600, it should work with other manufacturers products as long as they follow a similar API. The Xyplex devices that I have are 16 port devices that connect serial devices to an ethernet network.
If COMSERV sounds useful to you, feel free to download and use it. The program is provided in source form, so you will need to extract it and compile it. If you use FreeBSD, simply do the following:
% cd /usr/ports/comms/comserv
% make install
I use it on FreeBSD 4-STABLE. I dont currently know of any outstanding bugs, but if you find and fix any bugs, please send me your fixes so that others can benefit from them as well.
If you do decide to use COMSERV, please note the accompanying license. In a nutshell, you can use it without restriction as long as you credit me and keep the copyright notice intact. If you happen to like it, feel free to send your thanks, letting me know. If you dont like it, let me know why, perhaps I can improve it. If you improve it, please send me your changes and Ill see about integrating them so that others can benefit from your improvements.
Enhancements:
- Implement a power of 2 backoff and retry for failing connections with a maximum 10 minute wait. This keeps from filling up the logs with failed repeated attempts.

Home Media Librarian provides an application to catalog records, CDs, DVDs, etc.

HML is a pure Java client(GUI) application to catalog records, cds, dvds, etc.
HML requires a JDBC compliant database and driver.

The application is for the average person whom has a record, cd, dvd, tape, etc. music collection and wants to catalog this collection.

It has been tested with JDK 1.3 and 1.4 on Macintosh OSX, Linux, and Windows 2000 using MySQL and Connector J.

The distribution includes the software,documentation, and source code.

Computer Temperature Monitor is a little applet for the GNOME desktop that shows the temperature of your computer CPU and disks on screen. Computer Temperature Monitor also allows you to log temperatures to a file.
You can set alarms to notify you when a tempertature is reached. Several monitors can be added to the panel to monitor different sensors. It is designed to look like the CPU Frequency Gnome applet. This applet used to be called Laptop Temperature Monitor.
Enhancements:
- The way the temperature file is read has been changed to fix a bug in some modules (acpi, ibm_acpi, i8k, and omnibook).
- Support has been added for Apple G5 computers (windfarm sensors).
- Support has been added for dynamic log filenames using patterns.
- A bug that prevented the icon from appearing sometimes has been fixed.
- A GConf key has been added for showing debug information in the applet tooltip.
- A Simplified Chinese translation has been added.
- Support has been added to change the logging timeout.
- There are some bugfixes.
