There is an ongoing information war raging in the software world. Despite free software developers’ best efforts, new proprietary software continues to proliferate. Improved techniques must be developed to reverse engineer efficiently closed data formats so that free, interoperable solutions can be deployed under Linux.

Software reverse engineering occurs on various levels. It may be necessary to study a piece of poorly written, poorly commented code developed in a high-level language such as C++ and understand what the original program was supposed to accomplish. It may also be necessary to disassemble a program that has been compiled into machine language and express it as a higher-level language. In doing this, the underlying algorithms can eventually be expressed as higher-level concepts in a human language. After obtaining an algorithmic description via reverse engineering, the algorithm can be reimplemented for any language on any computing platform.

How to setup a Web Server in a Linux or MS-Windows environement with Tomcat, Apache and the WARP Connector (WebApp).

Be careful that the new versions (Apache 2 and tomcat 4) needs some particular changes. I will try to integrate them, but for now, check the Chapter 5 at the end of this document ! Besides, consider using Tomcat stand-alone : if it is fast enough, don’t loose your time until the connector configuration is more stable. Enventually consider RESIN ($500) [http://www.caucho.com/] or Orion ($1500) [http://www.orionserver.com/], whish are much cheaper than the well known BEA WebLogic or IBM WebServer.

Typical content distribution solutions are based on placing dedicated equipment inside or at the edge of the Internet. The best example of such solutions is Akamai [1], which runs several tens of thousands of servers all over the world. In recent years, a new paradigm for Content Distribution has emerged based on a fully distributed architecture where commodity PCs are used to form a cooperative network and share their resources (storage, CPU, bandwidth).

Introduction Studies have shown that over 90% of computer viruses spread by e-mail. Virus writers often take advantage of the most commonly used e-mail and groupware systems in order to maximize the speed and effects of viruses. By discovering vulnerabilities in different e-mail systems, they are able to create viruses that are more and more complex and destructive. F-Secure Linux Server Security can be utilized with an existing Mail Transport Agent (MTA) to effectively protect computers against viruses and other malicious content. It protects your corporate network, and also ensures that your company does not send out infected e-mail messages to customers or business partners.
