Azureus - now called Vuze - Bittorrent Client

Azureus is a BitTorrent client written in Java. The BitTorrent protocol is a new way of exchanging or distributing data over the internet. Downloading also means uploading, and the amounts of each are linked, to ensure fairness and rapidity in the spread of the file at hand.

For information on how to set up Azureus, see the Initial_Setup_Guide

To be able to download a file, you first need to get the associated .torrent file. This file, usually a dozen KB in size, is the “signature” of the much bigger file to be downloaded, and it needs special software to be read properly. Azureus is one of those types of software.

If you want to host files yourself, you need a tracker, which is basically a central server coordinating the connections between peers. Azureus can provide a tracker too.

You will find, as you discover its functionality, that it is easy to customize your copy of Azureus to exactly fit your needs. This guide is being developed on basis of an older User Guide and the 3.0.3.4 version of Azureus (Windows and Macintosh versions).

eMule

What is eMule?
At dawn of May 13th 2002 a guy called Merkur was dissatisfied with the original eDonkey2000 client and was convinced he could do better. So he did. He gathered other developers around him, and eMule Project was born. Their aim was to put the client back on track where eDonkey had been famous before, adding tons of new features and a nice GUI. They couldn't imagine what impact this decision would have...

As of today, eMule is one of the biggest and most reliable peer-to-peer file sharing clients around the world. Thanks to it's open source policy many developers are able to contribute to the project, making the network more efficient with each release.

A list of a few features available.

• Clients use several networks to create one reliable network. (ED2K, Source Exchange, Kad)
  • Kad is now in an open testphase, eMule v0.42 can be enabled to use Kad
• eMule's Queue and Credit system helps to ensure that everyone will get the file he wants by promoting those that upload back to the network.
• eMule is completely free. eMule is also completely free of any Adware, Spyware, and ect. We do this for fun and knowledge, not for money.
• Each file checked for corruptions while downloading to ensure an error free file.
• The eMules Intelligent Corruption Control helps to speed up the correction of corrupted parts.
• Auto priorities and Source management allows you to start many downloads without having to monitor them.
• The Preview function allows you to look at your Videos and Archives before they are completed. For video previewing, we recommend the Video Lan Client.
• The eMule features webservices and a webserver that allows you to have quick access to and from the internet.
• You can create categories for your download to organize them.
• To find the file you want, eMule offers a wide range of search possibilities which include: Servers (Local, and Global), web based (Jigle, and Filedonkey), and Kad (Still in Alpha).
• eMule also allows you to use very complex Boolean searches that make the searches much more flexible.
• With the messaging and friend system, you can send messages to other Clients and add them as friends. In your friend list, you can always see if a friend is online.
• With the build in IRC client, you can chat with other downloaders and chatters around the globe.
