Free 3.0 beta software for linux

LFT (Layer Four Traceroute) is a sort of "traceroute" that often works much faster than the commonly-used Van Jacobson method and goes through many configurations of packet-filter based firewalls.
More importantly, LFT implements numerous other features, including AS number lookups through several reliable sources, loose source routing, netblock name lookups, and more.
LFT project also distinguishes between TCP-based protocols, which make its statistics slightly more realistic, and gives a savvy user the ability to trace protocol routes, not just layer-3 hops.
Whats New in 3.0 Beta Development Release:
- The program was completely refactored and is now a workable C library to call from other programs.
- Many memory management issues were fixed.
- Several 2.6b5 features were cleaned up.
- Adaptive mode now detects and differentiates flag-based from stateful firewalls.

RakNet project is a reliable UDP networking API.
RakNet is a networking API that is a wrapper for reliable UDP and higher level functionality on Windows, Linux, and Unix.
It allows any application to communicate with other applications on the same computer, over a LAN, or over the internet.
Although it could be used for any networked application, it was developed specifically for rapid development of online games and the addition of multiplayer to single player games.
Main features:
- Secure connections
- With one line of code Raknet will automatically use SHA1, AES128, SYN Cookies, and RSA to prevent connection spoofing, replay attacks, data eavesdropping, packet tampering, and MitM attacks. Overhead averages 12 bytes per datagram.
- Voice communication
- Using Speex for encoding / decoding, 16 bit audio can be transmitted using approximately 1000 bytes per second.
- Remote terminal
- Using either Telnet or secure RakNet, you can remotely administrate your applications. The system has built-in commands for most RakNet functions and is designed for users to extend for their own purposes. Example capabilities include application resets, password management, and logging.
- Application directory server
- The application directory server allows servers to list themselves for clients to find and connect to. The system uses a key / value system. Listing your server and posting new rules are both done with a single line of code.
- Autopatcher
- Update your users with database driven binary delta patches, or use a simpler version for updates such as user skins or maps.
- Object replication system
- RakNets object and memory replication system provides a framework from which you can synchronize your program state. It requires no changes to your program architecture and there is no unneeded overhead. Memory is replicated through a single function call, with support for callbacks for serialization of complex types such as pointers.
- Network traffic compression
- The BitStream class allows compressed writes of vectors, matrices, quaternions, and real numbers between -1 and 1. It also supports delta compression, by which unchanged values only use a single bit.
- Remote function calls
- While you can send and interpret your own bit streams, remote function calls make this process easier as you now deal with functions rather than raw data. Remote function calls only take 1-2 bytes of overhead and allow both static C function calls and class member function calls. Return values are also supported.
- Routing and multicasting
- RakNet supports automatically updated connection graphs, which are used for routing and multicasting via a minimum spanning tree. You could, for example, use RakNet for highly efficient distributed peer-to-peer file sharing. Simpler applications include directed messages between clients and efficient broadcasts.
- Robust communication layer
- Flow control, message ordering on different channels, message coalescence, and splitting and reassembly of packets larger than the MTU are transparently handled for you.

Gateway is a JavaEE application developed by the Vermont Department of Taxes. It provides a web services framework for accepting Streamlined Sales Tax registrations and returns.

The project also includes a web interface for manually submitting transmissions. The goal is to build an extensible framework upon which future tax services can be built.

SmoothWall Express is an open source firewall distribution based on the GNU/Linux operating system.
Linux is the ideal choice for security systems; it is well proven, secure, highly configurable and freely available as open source code.
SmoothWall includes a hardened subset of the GNU/Linux operating system, so you dont have to install any separate OS.
Designed for ease of use, SmoothWall is configured via a web-based GUI, and requires absolutely no knowledge of Linux to install or use.

OpenXava is a framework to develop easily business applications with XML and Java.

OpenXavas virtue resides in the fact that the heart of our applications is XML instead of Java.

No Java classes, no XML files for mapping objects, no design of JSP or JSF pages, simply no more.

OpenXava generates for you a complete J2EE application (with CMP EJB or Hibernate for persistence) like this, and with a suitable User Interface for manage your Teachers.

The resulting application allows you make CRUD operations, searching, filtering, ordering, generating reports in PDF format, exporting to Excel, etc.

In spite of its rapid development features, OpenXava is flexible enough to allow you to put your custom code in any part of the application.

With only simple XMLs and Java code in JavaBean format (really reusable Java classes) you can construct any J2EE business application in a very productive way. In fact, a lot of critical business application, now in production, have been developed with OpenXava.

Whats New in 2.2.1 Stable Release:

The button bar is not shown if it is empty. More meaningful titles for PDF reports are displayed in collections. A new property, emailAsUserNameInPortal, was added for usin in xava.properties that allows Users.getCurrent() to return the user email instead of the user id inside a portal. A new display-size attribute is available in property-view, and scale validation is done for MONEY/DINERO stereotype. Mode.list link is not available when creating or modifing a reference. In general, change mode actions are not available after view navigation, and many other features have been added.

The Generic Eclipse Modeling System (GEMS) is a MDD tool for Eclipse that allows for the rapid development of Draw2D plugins.
Developers specify the rules for a domain language using a metamodel and the tool generates a diagram editor plugin that enforces the rules from the metamodel.
Interpreters can then be written to traverse the model and generate code, perform analyses, or execute the model.
Whats New in 2.0.5_01 Stable Release:
- This release contains fixes to minor bugs present in 2.0.5.

Tulip is a software system dedicated to the visualization of huge graphs. It manages graphs with up to 500,000 elements (node and edges) on a personal computer (PIII 600, 256MB RAM).

Its SuperGraph technology architecture provides the following features: 3D visualizations, 3D modifications, plugin support, support for clusters and navigation, automatic graph drawing, automatic clustering of graphs, automatic selection of elements, and automatic coloring of elements according to a metric.

Garidio is an application that allows users on a network to share the contents of their desktop clipboards with each other.

It has been successfully tested on Mac OS X (Tiger), Windows XP (SP2), and Linux (Slackware, SuSE, and Ubuntu), but it should work fine on any system with a working JVM for Java 1.5.
