Free frees software for linux

FreeS/WAN is an implementation of IPSEC & IKE for Linux. IPSEC is Internet Protocol SECurity. It uses strong cryptography to provide both authentication and encryption services. Authentication ensures that packets are from the right sender and have not been altered in transit. Encryption prevents unauthorised reading of packet contents. These services allow you to build secure tunnels through untrusted networks.

Two protocols are used

ESP (Encapsulating Security Payload) provides encryption plus authentication
IKE (Internet Key Exchange) negotiates connection parameters, including keys, for ESP

Freeswan implementation has three main parts:

KLIPS (kernel IPsec) implements ESP, and packet handling within the kernel
Pluto (an IKE daemon) implements IKE, negotiating connections with other systems
various scripts provide an adminstrators interface to the machinery.

Because IPsec operates at the network layer, it is remarkably flexible and can be used to secure nearly any type of Internet traffic. Two applications, however, are extremely widespread:

a Virtual Private Network, or VPN, allows multiple sites to communicate securely over an insecure Internet by encrypting all communication between the sites.
"Road Warriors" connect to the office from home, or perhaps from a hotel somewhere

There is enough opportunity in these applications that vendors are flocking to them. IPsec is being built into routers, into firewall products, and into major operating systems, primarily to support these applications. See our list of implementations for details.

We support both of those applications, and various less common IPsec applications as well, but we also add one of our own:

opportunistic encryption, the ability to set up FreeS/WAN gateways so that any two of them can encrypt to each other, and will do so whenever packets pass between them.

This is an extension we are adding to the protocols. FreeS/WAN is the first prototype implementation, though we hope other IPsec implementations will adopt the technique once we demonstrate it. See project goals below for why we think this is important.

A somewhat more detailed description of each of these applications is below. Our quickstart section will show you how to build each of them.

Free Tennis is a tennis simulation developed by a former tennis player. Its main feature is realism.
For gameplay, this means you have total control over the shot parabola. For graphics, it means players have realistic gestures. For AI, it means real tactics.
Free Tennis is a tenis simulator game.
Main features:
- Real tactics are useful in the game (e.g. it is best to take the net with a slow, low shot (backspin); it is best to play diagonal in order not to give angles, especially when you are decentered; you should get back to center after the shot, and not be caught in no-mans-land when the opponent hits; etc.);
- The A.I. is very advanced and reflects those tactics;
- You have total control over the parabola described by the shot;
- The graphic gestures are realistic and elegant;
- Different players have different skills;
- The game is developed by a former tennis player;
- Free Tennis is Free Software (which means more than simply "open-source"). It is released under the GPL license. Should you need another license, please ask the author.

Help desk software is vital to the success of your help desk and customer support staff. Tracking and responding to help desk calls is faster and more efficient when using well designed help desk software.
The design of this software comes from many years of help desk experience working in a help desk environment. All the basic tools for running a successful help desk are included in this help desk software package.
Help desk software should be used in any organization whether its a large corporation or a small startup company. Why should my company implement a helpdesk software solution? Some of the benefits of helpdesk software are improved customer service, faster response times and lower information technology costs. Lets outline these three areas in greater detail.
When a user contacts the computer support professional in your organization, what steps are taken? Does it depend on who answered the phone? Do the immediately drop any task and visit your desk? Do they jot your information down on a note pad? Do they attempt to resolve the issue on the phone at great length? What criteria merits the call be moved to another member of the IT staff, or merits a call the software vendor?
All these questions can be answered in some way within the use of help desk software. Helpdesk software forces your IT staff to handle help desk calls in a structured manner that can be counted on each time. When a helpdesk call is received, it should be immediately be entered into the help desk software database, even if it is easily answered.
At this point there is now a record of the call, and this allows other IT staff to view the contents of the problem and makes it a simple task for other IT staff members to offer solutions. This also prevents the call from being lost in the shuffle if staff is busy when the call is received. Your general staff will have much more confidence that when they place that call to your help desk staff, their call will be handled in a structured method to ensure their satisfaction.
If they can continue to work, they will not feel the need to keep calling or checking with IT staff on the progress, or worry that their call will not be answered in a reasonable amount of time. This allows them to focus on their tasks, and not be concerned with the status of their call.
Many help desk software solutions offer a self-help method, allowing the staff members in your company to submit a helpdesk request directly into the help desk system. (granted their computer is functioning enough for this) This feature greatly streamlines the process, and can increase response time for all users. Help desk support staff will not be interrupted by the phone call and have to stop working on another issue to record the call information.
In fact, it should be encouraged by the IT staff to submit all request possible with this method. When a request is entered into the system, it allows any available support personnel to respond to the request. It also allows support personnel to diversify calls, so if a calls is shown to be about a particular problem that a staff member has greater expertise with, that staff member will likely be able to solve the problem much quicker. Once each calls is resolved, the solution will then become available for future reference.
This is one of the greatest benefits an organization will receive from using a help desk system. This allows newer support staff to be able to answer many questions by simply searching the database for other calls. Also prevent 2 support staff from having to research for the same solution, this benefits in much faster response time for the end user.
Everything mentioned above will contribute to the overall quality of service in your organization, happier staff and faster response time will mean lower costs and higher productivity for your organization.
Enhancements:
- This release fixes a bug found in the main form that caused some performance problems in certain system configurations.

Free Reign project consists of a fully-3D city simulator.
Free Reign is a fully-3D city simulator, with advanced features planned such as ore mining, advanced financial models, and other features users request.
Main features:
- Crashes on demand
- OpenGL based graphics
- Fully 3D (rotateable map etc)
Installation
At the current time, installation of the game is by simply compiling and running the game in the compile directory. Compilation is standard:
Type ./configure in the FreeReign directory
Type make when configure succeeds.
Change to the src directory
Type ./fr to run the game
Enhancements:
- Bug fix in getMinHeight/Max - ugh. How did I ever forget that? My last C++ compiler must have assumed I was returning height..my God.
