Proximate is a social peer-to-peer (P2P) application designed for local device to device networking. It provides social communities with several user functions: Messaging, file sharing, and message boards. The application is designed to be completely P2P, i.e. servers are not needed. It only assumes TCP/IP networking, which means that it works over wireless/wired links such as ad hoc WLAN and Ethernet LAN. The application is written in Python for GNU/Linux systems with a GTK+ GUI, Nokia N900 being the primary platform.
Although widely used, currently popular peer-to-peer (P2P) applications offer no user privacy. By design, services like BitTorrent and Gnutella share data with anyone that asks for it, allowing a third-party to systematically monitor user behavior. As a result, using a P2P network means that your online activities become public knowledge. OneSwarm is a peer-to-peer tool that provides users with explicit control over their privacy by letting them determine how data is shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, shared with friends, shared with some friends but not others, and so forth.
RHash is a utility for computing hash sums and creating magnet links. It supports CRC32, MD4, MD5, SHA1/SHA2, Tiger, TTH, Torrent BTIH, AICH, ED2K, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R 256/512, WHIRLPOOL, and SNEFRU hash algorithms. Hash sums are used to ensure and verify the integrity of large volumes of data for long-term storage or transferral. RHash can calculate magnet links and EDonkey 2000 links. It can update existing hash files by adding sums of files missing in the hash file. It can output in a predefined (SFV, BSD-like) or user defined format. It can process directories recursively.
The overall objective of the XtreemOS project is the design, implementation, evaluation, and distribution of a grid operating system (called XtreemOS) with native support for virtual organizations (VO). XtreemOS is capable of running on a wide range of underlying platforms, from clusters to mobiles. It is based on Mandriva Linux, with support to come for other distributions later.
pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NAT gateways to communicate with a server behind a separate NAT with no port forwarding and no DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect, nor does it need to communicate with any other hosts in order to initiate the communication. Simply put, this is a proxy server that works behind a NAT, even when the client is behind a NAT. There is no middle man, no proxy, no third party, no UPnP required, no spoofing, and no DNS tricks. More importantly, the client can then connect to any host or port on any remote host or to a fixed host and port decided by the server.
P2P-Fusion is a software system that supports audiovisual creative activities and makes it easy for anyone to create, reuse, and share audio and video productions over the Internet legally, without costly servers and complicated system management. Fusion binds together a peer-to-peer network, a distributed semantic database, social enrichment features, support for embedded licenses, and a social media application toolkit into an integrated easy-to-use solution.
