Free file sharing software for linux

Freenet software lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack.
Communications by Freenet nodes are encrypted and are "routed-through" other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.
The network can be used in a number of different ways and isnt restricted to just sharing files like other peer-to-peer networks. It acts more like an Internet within an Internet. For example Freenet can be used for:
Publishing websites or freesites
Communicating via message boards
Content distribution
Unlike many cutting edge projects, Freenet long ago escaped the science lab, it has been downloaded by over 2 million users since the project started, and it is used for the distribution of censored information all over the world including countries such as China and the Middle East.
Ideas and concepts pioneered in Freenet have had a significant impact in the academic world. Our 2000 paper "Freenet: A Distributed Anonymous Information Storage and Retrieval System" was the most cited computer science paper of 2000 according to Citeseer, and Freenet has also inspired papers in the worlds of law and philosophy. Ian Clarke, Freenets creator and project coordinator, was selected as one of the top 100 innovators of 2003 by MITs Technology Review magazine.
Enhancements:
- This release operates over UDP rather than TCP.
- It can transparently operate through firewalls.
- The core architecture and algorithm have been redesigned for simplicity and efficiency.
- A new and even simpler API allowing the rapid development of third party software that interacts with Freenet has been added.

LimeWire is a multi-platform Gnutella client with nice features like auto-connect, groups, browse host, multiple search, upload throttling, connection quality control, library management and sophisticated filtering. LimeWire is built for the both the novice and power user.
LimeWire allows you to search for multiple files at the same time, available in several different languages, and is most famous for its ease-of-use and cross compatibility.
LimeWire will run on Windows, Macintosh, Linux, Sun, and other computing platforms.
Main features:
- Ease of use - just install, run, and search
- Ability to search by artist, title, genre, or other metainformation
- Elegant multiple search tabbed interface
- "Swarm" downloads from multiple hosts help you get files faster
- iTunes integration for Mac users
- Unique "ultrapeer" technology reduces bandwidth requirements for most users
- Integrated chat
- Browse host feature--even works through firewalls
- Added Bitzi metadata lookup
- International versions: Now available in many new languages.
- Connects to the network using GWebCache, a distributed connection system
- Automatic local network searches for lightning-fast downloads. If youre on a corporate or university network, download files from other users on the same network almost instantaneously!
- Support for MAGNET links that allow you to click on web page links that access Gnutella.

MUTE File Sharing is a peer-to-peer network that provides easy search-and-download functionality while also protecting your privacy.
It compiles as a fast, native application for many platforms (no Java, no Python, etc.).
MUTE protects your privacy by avoiding direct connections with your sharing partners in the network. Most other file sharing programs use direct connections to download or upload, making your identity available to spies from the RIAA and other unscrupulous organizations.
MUTE is based on research, and experiments show that it works quite well. MUTEs ant-inspired routing is light-weight, robust, and adaptive. Results from experiments in real MUTE networks show that the collective behavior of MUTE nodes quickly finds the shortest (or fastest) routing path between two nodes on the network.
Enhancements:
- This release fixes bugs in MUTEs initial connection to the network upon startup.
- MUTE has also been upgraded to Crypto++ 5.4, so it should now compile using GCC 4.1.

DC# is an easy to use file sharing client.
DC# is a file sharing client for the Direct Connect protocol.
Main features:
- Hub and private messaging
- Searching
- File transfer
- Innovating user interface

Noname Network provides a powerful file-sharing network.

The Noname network is a gnutella-based network that features a different and more flexible protocol. The client and network currently support filesharing, but the protocol can be extended to support more features.

Web Sharing is a small tray applet for sharing files on the web.

Publish anything on the Internet or your local area network at home, office or school from a folder on your hard disk with just a few clicks of a mouse!
