Free gnutella legal software for linux

Gtk-Gnutella is a server/client for Gnutella. It runs on every Unix-like system which supports GTK+ (1.2 or above) and libxml. Gnome is not required.
It is currently developed and tested under Linux (Debian 2.2) and is known to run at least on Linux, FreeBSD, NetBSD, OpenBSD, Darwin, Solaris, Tru64 UNIX (OSF/1), SGI IRIX, BeOS whereas CPU architectures include x86, AMD64, PowerPC, SPARC, MIPS.
gtk-gnutella project is released under the GNU General Public License (GPL).
Gtk-Gnutella is not finished yet, but it is fully functional: you may share, search, and download. And it is stable too, users usually just leave it run unattended for days.
Main features:
- Share files on the gnutella network (Limewire, BearShare, Xolox, Gnucleus, Shareaza, Morpheus ...)
- Compressed GNet connections
- Simultaneous downloading of files from multiple hosts (swarming)
- Passive searches
- Searching by urn:sha1: and magnet:
- Automatic aquisition of additional sources via download mesh and watching searches
- Powerful filtering engine
- Bandwidth management/limiting
- A lot of settings
- A lot of statistics
Enhancements:
- Features include server-side support for Tigertree hashes and THEX, improved spam filters, paused downloads, and a query syntax for easier creation of result filters.
- There were also many bugfixes and other changes.

Qtella is a peer-to-peer client using Gnutella protocol.
Sharing files over decentralized networks (peer-to-peer) has become very popular. The Gnutella network (Gnet) is one of these p2p networks which is an open network. The advantage of a decentralized network is that no server exists, which could be a single point of failure. Instead, every client acts as client and server at the same time. Due to this fact these clients are often called Servents. But using decentralized networks has also disadvanteges. The main drawback of missing central servers is that connecting to the net takes longer.
Qtella is one of these servents for Linux for the Gnutella network with many useful features. Most of these features are taken from the comments and suggestions of Qtella users. I want to thank all of these users. Qtella is written in C++ and uses the Qt libraries. It is available for Linux/Unix. Also a developer version for the Sharp Zaurus exists. A Win32 version is currently in progress (an alpha version is already available but its very unstable). [cCOPYRIGHT=1]

JSothello is a Javascript/DHTML implementation of the board game "Othello", also called "Reversi". Runs in the browser with four challenging computer intelligence levels. Play human versus computer, human versus human or computer versus computer.
JSothello is a Javascript/DHTML implementation of the board game "Othello", also called "Reversi".
Othello is very easy to play. The board is a square grid of any size. The two players pieces are black or white. Each player must place a piece on the board adjacent to one of his opponents pieces so that another of his own pieces is on the other side of his opponents piece(s). In other words, the opponents piece(s) should be "sandwiched" between the players pieces. When that occurs, all such "sandwiched" pieces are changed to the players color.
The game ends when one player cannot make a legal move. The winner is the player with the most pieces on the board.
This version allows the user to play the computer, another human or watch the computer play itself. The computer players have four levels of "intelligence", each with different styles of play:
- "Only took a minute to learn": The computer chooses random (legal) moves.
- "Laughable": The computer picks (one of) the move(s) that will flip the most pieces.
- "Respectable": Plays like "Laughable" but tries to grab the edges and the corners whenever possible while keeping its opponent from being able to grab the edges and corners.
- "Took a lifetime to master": Plays like "Respectable" but adjusts its edge/corner bias as the board fills up, favors moves that flip pieces in more than one direction, tries to prevent moves that will allow the opponent to immediately reverse its gain and places pieces closer to the corners when possible.

DeltaMUD project is a MUD-online game server software.

DeltaMUD is a MUD server based on enhancements to the original CircleMUD bpl12 source code and is thus bound to the legal terms contained within the CircleMUD and DikuMUD license agreements.

The goal of this project is to provide an enhanced, memory optimized, and SQL-based version of the original CircleMUD.

DContract project is a Java5 toolbox library for the management of digital contracts.
You can use this toolbox to put signatures on digital documents, and to verify signed documents. It also offers XML Advanced Electronic Signatures (XAdES) 1.3.2 support, up to XAdES-X-L.
Main features:
- Signing, co-signing and counter-signing of digital documents.
- Robust verification of digital signatures with the possibility to extend the verification framework with both document resolvers and key resolvers.
- The signature framework can be extended with self-defined signature aspects.
- XML Advanced Electronic Signatures (XAdES v1.3.2 2006-03) support: XAdES-BES, XAdES-EPES, XAdES-T, XAdES-C, XAdES-X, XAdES-X-L.
- Provides an easy-to-use abstraction level for creating legal signatures.
- Document repository to load/store XML DOM documents from/to various sources.
- Document schema validation with easy-to-use extendible schema catalog.
- Generation of RSA key pairs up to 2048 bit.
- Generation of self-signed X509 certificates, supporting the most common extensions.
- PKCS12 key repository management.

Enhancements:
- This release includes a major refactoring of the XAdES signature aspects, resulting in performance improvements.
- Because of the refactoring it is now also possible to upgrade, for example, a XAdES-BES signature to XAdES-T, and it is also easier to query a verified signature for some XAdES attributes.
- The Web site also has a new section on the architecture of DContract and a code sample.
- Some interop tests were performed with IAIK XAdES, and the FAQ now offers a comparison between DContract and the IAIK XAdES library.

Free Digital Money projetc is aimed at promoting ideas and stimulating further innovation in the field of digital bearer money.
Digital bearer money is like cash and can be transferred person-to-person without going through a bank or PayPal account.
Scope
The scope of this project is necessarily limited; digital bearer money schemes are difficult to implement.
The project will develop and release a Digital Money system and applications, suitable for teaching and idea-testing.
The current release (V0.2) delivers a basic digital PGP-based coin system.
The next release will provide a transport mechanism to send the coins to an intended recipient; and a client application (a Wallet).
How You Can Help
We welcome technical help in a variety of forms:
- Application writers and visionaries: to use the FreeDMoney software to experiment with new ideas
- Coders: to extend the current software or to implement a completely new payment system
- Vendors of existing digital payment schemes: to implement a FDM interface to their code
Educational Usage
Students (and others) are welcome and encouraged to use FreeDMoney as a basis for discussing other considerations of building a secure payment systems.
Examples:
- What technical peer-review process would be required to be confident in the security of the system?
- What are the limitations in the model that would need to be overcome in order to make this into a technically sound basis for a real-world, real-value payment system?
- Assuming these limitations had been overcome, what operational considerations would need to be addressed to deliver a secure, reliable payment system?
- How do existing payment systems address these issues?
What legal and regulatory issues would need to be addressed in the target jurisdictions?
Enhancements:
- Initial Coin implementation and "test bank" Web application.

Firepass - is a tunneling tool, allowing to bypass firewall restrictions and encapsulate data flows inside legal ones to use HTTP POST requests. TCP or UDP based protocols may be tunneled with Firepass. For now, both - client and server parts are written in Perl and the server script acts as a CGI program.
The Firepass key feature is that you may use several type of installation of the server part script in the external network. You do not need to bind any port on the external box. Firepass may also be usable for the reverse task, when the server script is located at the corporative web server and when client interact with it from the external network.
To run FIREPASS youll need the following dependencies:
A box located inside your local network, with Perl and the ability to send HTTP messages to the external network (Internet), either directly or indirectly through a HTTP proxy
A HTTPd server located on the external network (with Perl also) where you can place / run CGI scripts and establish outgoing connections (Most commercial hosting providers and some public ones allow this)
FIREPASS key feature is that you can chain several installations of the server and they never need to bind to a port; therefore, it is undetectable by most Administrators. There is only an unusual HTTP dialog between the client and server ; aswell, the HTTP messages are send fairly often. But this is configurable in the FIREPASS client with a special delay option between HTTP requests, and can be used for any non-time-critical protocols.
This FIREPASS version is alpha, so there still may be some bugs... including SECURITY bugs! Please read the section "HOW IT WORKS" carefully to understand all the possible risks you may be exposed to. I do not provide any guarantees that this program works properly.
Enhancements:
- New FIREPASS client directive :
- - use HTTP proxy to resolve hostnames.
- Minor corrections:
- A UDP protocol-related bug has been fixed in the client.
