eMule is a free peer-to-peer file sharing application for Microsoft Windows and Linux. Started in May 2002 equally an alternative to eDonkey2000, eMule now connects to both the eDonkey network and the Kad network. The distinguishing features of eMule are the direct exchange of sources between customer nodes, fast recovery of corrupted downloads, and the use of a credit organisation to reward frequent uploaders. Furthermore, eMule transmits data in zlib-compressed class to save bandwidth.

eMule is coded in C++ using the Microsoft Foundation Classes. Since July 2002 eMule has been gratis software, released under the GNU Full general Public License; its popularity has led to eMule's codebase being used equally the ground of cantankerous-platform clients aMule, JMule, xMule, along with the release of many eMule mods (modifications of the original eMule) on the Cyberspace.

As of Baronial 2017, it is the fourth most downloaded projection on SourceForge, with over 685 million downloads.^[5]

Development was later restarted past the community every bit eMule Community; the latest stable version is 0.60d.^[4]

History [edit]

The eMule project was started on May 13, 2002 by Hendrik Breitkreuz (besides known as Merkur) who was dissatisfied with the original eDonkey2000 client. Over time more developers joined the effort. The source was starting time released at version 0.02 and published on SourceForge on July 6, 2002.

eMule was first released as a binary on Baronial 4, 2002 at version 0.05a. The 'Credit System' was implemented for the get-go time on September 14, 2002 in version 0.19a. The eMule project website started up on December eight, 2002.

Current versions (v0.40+) of eMule take added back up for the Kad network. This network has an implementation of the Kademlia protocol, which does not rely on fundamental servers as the eDonkey network does, but is an implementation of a distributed hash table.

Also added in recent versions were the power to search using unicode, allowing for searches for files in non-Latin alphabets, and the power to search servers for files with complete sources of unfinished files on the eDonkey network.

In new versions, a "Bad source listing" was added. The application adds an IP address to this list after one unsuccessful connexion. After adding an IP to the "Bad source listing", the application treats this IP every bit a "dead" IP. Unavailable IPs are banned for a time period from 15 to 45 minutes. Some users have complained that it leads to a loss of active sources and subsequently slows download speed.

Other recent additions include: the ability to run eMule from a user account with limited privileges (thus enhancing security), and Intelligent Corruption Handling (so that a corrupted clamper does not demand to be re-downloaded entirely).

The 0.46b version added the cosmos and direction of "eMule collection" files, which contain a fix of links to files intended to be downloaded as a set.

From 2007, many ISPs take used bandwidth throttling for usual P2P ports, resulting in slow performances.^[6] The 0.47b version adds protocol obfuscation and eMule will automatically select 2 port numbers at random in the startup wizard.

Basic concepts [edit]

File transfer statistics of 5.048a

Each file that is shared using eMule is hashed as a hash list comprising divide 9500 KiB chunks using the MD4 algorithm. The top-level MD4 hash, file size, filename, and several secondary search attributes such as scrap rate and codec are stored on eD2k servers and the serverless Kad network.

Search parameters in eMule v0.50a

Users can search for filenames in the servers/kad and are presented with the filenames and the unique identifier consisting of the top-level MD4 hash for the file and the file's size that tin can exist added to their downloads. The client then asks the servers where the other clients are using that hash. The servers render a set of IP/ports that point the locations of the clients that share the file.

eMule so asks the peers for the file. eMule will then be queued until an upload slot becomes available.

When a complete chunk of 9,728,000 bytes (9500 KiB) is downloaded and verified, this data is also shared by the downloader, helping others to download the file as well.

It is also possible that a customer knows other clients that are too sharing that same file. In that case a source substitution between the clients is made. This exchange of known peers is done straight betwixt the peers.

Newer versions of eMule back up AICH (Advanced Intelligent Corruption Handling). It is meant to make eMule's corruption handling competitive with BitTorrent. SHA-1 hashes are computed for each 180 KiB sub-clamper and a whole SHA-i hash tree is formed. AICH is candy purely with peer-to-peer source exchanges. eMule requires x agreeing peers regarding the SHA-1 hash, then rare files generally exercise non benefit from AICH.

Low ID [edit]

Users who cannot be reached from the outside considering they are firewalled, behind a NAT device that has not been correctly port forwarded, or whose IP address ends with a zero (e.g. 123.45.67.0)^[7] get a "Depression ID" from the servers. They are still able to upload and download simply demand the help of servers or other kad clients to be reached by other clients. Since they cannot be notified that they are in front end of an upload queue, they have to poll peers if an upload slot is bachelor. Since they cannot connect to any other Depression ID clients, they see only 40–60% ^[8] of the clients that a High ID can encounter. Their IP/ports are not exchanged betwixt other peers, limiting their possibilities for finding sources via eMule's pure-P2P source exchange.

A Low ID client also consumes a lot more data ^[9] on an eserver than a High ID customer due to the lowidcallbacks. Also, a releaser or heavy uploader that uses a releaser mod such as MorphXT or Xtreme that is forced to operate on a Low ID (hotel room, task) as well will observe that they will have trivial command over their upload priorities (peculiarly powershares) as the servers appear to limit their connexion-forwarding for each client, thus turning their upload queue to a contention situation where the first to exist able to become forwarding and discover an open slot gets information technology.

Credit system [edit]

Credits are not global; they are exchanged betwixt two specific clients. The credit system is used to advantage users contributing to the network, i.e. uploading to other clients. The strict queue system in eMule is based on the waiting time a user has spent in the queue. The credit system provides a major modifier to this waiting time by taking the upload and download between the two clients into consideration. The more a user uploads to a client the faster they advance in this customer's queue. The modifiers are calculated from the amount of transferred data between the ii clients. The values used tin be seen in the customer's details dialog. To view this information, right-click on any user and choose View Details.

All Clients uploading to y'all are rewarded by the credit system. Information technology does not matter if the client supports the credit arrangement or not. Not-supporting clients will grant you lot no credits when you upload to them. Credits are stored in the clients.met file. The unique user hash is used to identify the client. Your ain credits are saved by the client who owes you the credit. This prevents faking the credits. Your own credits cannot be displayed.

The computation formula for the Official Credit System is composed of two ratios as follows:^[10]

${\displaystyle {\textrm {Ratio}}_{1}={\frac {2\cdot {\text{Uploaded Total}}}{\text{Downloaded Total}}}}$

${\displaystyle {\textrm {Ratio}}_{2}={\sqrt {{\text{Uploaded Total}}+2}}}$

Both ratios are then compared and the lower one is used as the modifier. A few conditions exist:

• If the Uploaded Full is less than ane MB, then the modifier will remain at one.
• If the client uploads data but doesn't download any, the modifier will be fixed at ten.
• The modifier tin can but be between 1 and 10.

An exception to this rule applies but when a peer is assigned a "Friend Slot" after being added to the client's Friends list. This automatically assigns a reserved upload slot for that peer so that he/she can begin downloading regardless of the Credit rating. Only i Friend Slot tin be reserved so as to prevent any course of corruption such as upload bigotry.^[11]

eMule compared to other P2P applications [edit]

eMule is said to exist the virtually complete implementation of the eD2k protocol and its extensions^{[ past whom? ]}. eMule supports AICH, making its corruption handling competitive with BitTorrent. eMule likewise supports source exchanges, allowing it to essentially reduce the loads on the servers and Kad. With a Loftier ID and well-sourced downloads pre-caused by server and/or Kad, eMule is able to sustain the peer sources on these files independent longer later disconnection from eD2k and Kad.

eMule mods [edit]

As a popular open source program, eMule has many variants, unremarkably chosen mods. Some mods started every bit forks from official eMule versions and then continued to develop independently rather than modifying newer official versions. An example of this type of mod is the obsolete eMule Plus. Since eMule Plus forked off before the release of v0.30, the first official version to include Kad, eMule Plus does not support this feature mainly because the project evolution has been abandoned for nearly four years. Other current mods follow official eMule releases and make their ain releases based on each new release of the official version. Since distributed mods are required to publicly share their source lawmaking by the GNU General Public License, useful features created by mod developers can be quickly incorporated into an official version.

Fake eMule sites and malware [edit]

Due to the popularity and open up-source nature of eMule, some 3rd parties have created modified versions of it, which frequently contain spyware and other malware programs. Some imitation sites ask for credit carte du jour information or require the user to sign upwards for a paid membership. The official eMule is free and does non ask for such information.

These versions are usually establish via rotating advertisements sometimes placed on legitimate sites.^{[12] [13]}

Chinese mods of eMule customer [edit]

VeryCD's easyMule is a pop eMule client among Chinese users. Information technology has a simplified interface and lacks some advanced settings available in the standard eMule client. As of version 1.i it simply supports searching through the VeryCD database, though external eD2k links are accepted. Some criticized VeryCD for their misleading name "Dianlv" (Chinese: 电驴; pinyin: Diàn Lǘ ; lit. 'Electronic Donkey'; more often than not the Chinese name for eDonkey or eMule) and the site emule.org.cn, which is named "Dianlv (eMule) Chinese Site" (电驴(eMule)中文网站).^{[xiv] [15]}

[edit]

On July 29, 2017 was released a "Community Version" of eMule^[16] maintained by the official forum users. This version is available to download in a GitHub repository and is based on the latest official release or beta but contains boosted features and issues fixes fabricated by the community, prioritizing a more up-to-engagement version.^[17]
