Install Vuze on Linux

Vuze (previously Azureus) is a BitTorrent client used to transfer files via the BitTorrent protocol. Vuze is written in Java, and uses the Azureus Engine. In addition to downloading data linked to by .torrent files, Azureus allows users to view, publish and share original DVD and HD quality video content. Content is presented through channels and categories containing TV shows, music videos, movies, video games and others. Additionally, if users prefer to publish their original content, they may earn money from it. Azureus was first released in June 2003 at SourceForge.net, mostly to experiment with the Standard Widget Toolkit from Eclipse. It later became one of the most popular BitTorrent clients.
The Azureus software was released under the GNU General Public License, and remains as a free software application.

JDownloader is open source, platform independent, and written completely in Java. It simplifies downloading files from One-Click-Hosters like Rapidshare.com or Megaupload.com - not only for users with a premium account but also for users who don't pay. It offers downloading in multiple parallel streams, captcha recognition, automated file extraction, and much more. Of course, JDownloader is absolutely free of charge. Additionally, many "link encryption" sites are supported - so you just paste the "encrypted" links and JD does the rest. JDownloader can import CCF, RSDF and the new DLC files.
