eMule MorphXT is a peer-to-peer file sharing application for Microsoft Windows released under the GNU General Public License (GPL), as is its parent software eMule. [1]

Peer-to-peer type of decentralized and distributed network architecture

Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.

File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia, documents or electronic books. File sharing may be achieved in a number of ways. Common methods of storage, transmission and dispersion include manual sharing utilizing removable media, centralized servers on computer networks, World Wide Web-based hyperlinked documents, and the use of distributed peer-to-peer networking.

Microsoft Windows is a group of several graphical operating system families, all of which are developed, marketed, and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows NT and Windows Embedded; these may encompass subfamilies, e.g. Windows Embedded Compact or Windows Server. Defunct Windows families include Windows 9x, Windows Mobile and Windows Phone.

eMule connects to both the eDonkey network and the Kad network. The distinguishing features of eMule are the direct exchange of sources between client nodes, fast recovery of corrupted downloads, and the use of a credit system to reward frequent uploaders. Furthermore, eMule transmits data and control codes in zlib-compressed form to save bandwidth.

The eDonkey Network is a decentralized, mostly server-based, peer-to-peer file sharing network created in 2000 by US developers Jed McCaleb and Sam Yagan that is best suited to share big files among users, and to provide long term availability of files. Like most sharing networks, it is decentralized, as there is not any central hub for the network; also, files are not stored on a central server but are exchanged directly between users based on the peer-to-peer principle.

The Kad network is a peer-to-peer (P2P) network which implements the Kademlia P2P overlay protocol. The majority of users on the Kad Network are also connected to servers on the eDonkey network, and Kad Network clients typically query known nodes on the eDonkey network in order to find an initial node on the Kad network.

zlib software library

zlib is a software library used for data compression. zlib was written by Jean-loup Gailly and Mark Adler and is an abstraction of the DEFLATE compression algorithm used in their gzip file compression program. zlib is also a crucial component of many software platforms including Linux, Mac OS X, and iOS. It has also been used in gaming consoles such as the PlayStation 4, PlayStation 3, Wii U, Wii, Xbox One and Xbox 360.

History

The original eMule program was released under the GPL on 7 July 2002. The license allowed free modification of the software, and the first MorphXT mod was released on 21 January 2003 by a user using the name "morpheus". Between version MorphXT 2.0 and 8.3, the main developer used the name "SiRoB".

In September 2006 SiRoB announced he would cease development, since the French DADVSI copyright law made it illegal to develop peer-to-peer programs in France. [2] Since then releases have been less frequent, although whenever eMule increases its minor version number, MorphXT increases its major version number.

DADVSI

DADVSI is the abbreviation of the French Loi sur le Droit d'Auteur et les Droits Voisins dans la Société de l'Information. It is a bill reforming French copyright law, mostly in order to implement the 2001 European directive on copyright, which in turn implements a 1996 WIPO treaty.

Differences from eMule

MorphXT has the following additional differences to eMule:

Graphical user interface user interface allowing interaction through graphical icons and visual indicators

The graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

Windows NT is a family of operating systems produced by Microsoft, the first version of which was released on July 27, 1993. It is a processor-independent, multiprocessing and multi-user operating system.

Development

Several improvements first introduced in MorphXT have been incorporated back into the original eMule program.

The MorphXT team recently switched to using Git for version control, and keeps a private repository. The public repository on SourceForge is being updated as releases are made.

SourceForge Web-based source code repository

SourceForge is a web-based service that offers software developers a centralized online location to control and manage free and open-source software projects. It provides a source code repository, bug tracking, mirroring of downloads for load balancing, a wiki for documentation, developer and user mailing lists, user-support forums, user-written reviews and ratings, a news bulletin, micro-blog for publishing project updates, and other features.

Criticism

MorphXT's anti leeching system is based on static comparison of version strings. Some users have criticized [3] this method, because it bans some clients that are not actively leeching, but are potentially capable of doing so. In addition, since the software adds functionality to the already complex eMule program, it can become too complex for many users.

Fake version

Several versions of MorphXT have been released demanding a fee to download the software.[ citation needed ]

aMule software

aMule is a free peer-to-peer file sharing utility that works with the EDonkey network and the Kad network, offering similar features to eMule and adding others such as GeoIP. On August 18, 2003 it was forked from the xMule source code, which itself is a fork of the lMule project, which was the first attempt to bring the eMule client to Linux. These projects were discontinued and aMule is the resulting project, though aMule has less and less resemblance to the client that sired it.

BitTorrent is an ad-supported BitTorrent client developed by Bram Cohen and BitTorrent, Inc. used for uploading and downloading files via the BitTorrent protocol. BitTorrent was the first client written for the protocol. It is often nicknamed Mainline by developers denoting its official origins. Since version 6.0 the BitTorrent client has been a rebranded version of µTorrent. As a result, it is no longer open source. It is currently available for Microsoft Windows, Mac, Linux, iOS and Android.

In computing and specifically Internet, a leech is one who benefits, usually deliberately, from others' information or effort but does not offer anything in return, or makes only token offerings in an attempt to avoid being called a leech. In economics, this type of behavior is called "free riding" and is associated with the free rider problem.

Tribler Peer-to-peer filesharing software and protocol

Tribler is an open source decentralized BitTorrent client which allows anonymous peer-to-peer by default. Tribler is based on the BitTorrent protocol and uses an overlay network for content searching, which makes the program operate independently of external websites and renders it immune to limiting external action such as government restraint. Due to this overlay network, Tribler does not require an external website or indexing service to discover content. The user interface of Tribler is very basic and focused on ease of use instead of diversity of features. Tribler is available for Linux, Windows, and OS X.
