Free p2p software for linux

JXTA platform is an open network computing platform designed for peer-to-peer (P2P) computing. The JXTA platform standardizes the manner in which peers:
- Discover other peers
- Advertise Peer resources (Peer, PeerGroup, Service and Pipe Advertisements)
- Communicate with each other (Pipes)
- Cooperate with each other to form secure peer groups (group membership)
The Platform project is a Java Standard Edition reference implementation of the JXTA protocols.
The Platform project was the original JXTA implementation and was built in Java, because Java enabled us to rapidly prototype and test new ideas and develop a more robust implementation.
Java is available on most client platforms (Unix, Windows, MacOS X, etc.) and allows us to reach the maximum number of potential users.

iptables-p2p is an iptables match module capable of matching various peer-to-peer networks. It works by examining the application-layer protocol.
This is how you install iptables-p2p:
1. Copy the iptables headers to an appropriate place (/usr/include) or install the iptables-dev package if your distro has one. (see Installing iptables headers)
2. Run make in order to compile iptables-p2p.
3. Insert the kernel/ipt_p2p.o module directly using insmod or copy it into your modules directory. If you are using a 2.6 kernel, the module is named kernel/ipt_p2p.ko.
4. Insert the iptables library libipt_p2p.so into the iptables lib directory (usually /lib/iptables).
Enhancements:
- 0.3.0a
- Fixed iptables-save/iptables-restore
- Fixed module versioning support

Anatomic P2P is a BitTorrent Client written in GTK with an extension enabling decentralisation.

It is written in pygtk using the original core of BitTornado and it can access the Anatomic P2P network of supernodes and trackers so that files can be swarmed over multiple nodes on the network creating great efficiency.

Phex is a P2P filesharing client which is based on the Gnutella network. Phex offers advanced functions and integrates all common Gnutella extensions like multi-source downloads and advanced search features.
Main features:
Phex is a FREE of spyware and adware
- Phex never containd any kind of spyware, adware or any other kind of bundled software.
Multi-plattform support
- Whether you use MAC OS X, Linux, Solaris, or Windows Phex is able to run on them all. All you need is a operation system that offers a Java 1.4 Runtime Environment.
Multi-source downloads (Swarming)
- Often the file you like to download is available on different hosts. Phex will request different segment of the file from each host in parallel. After successfully downloading a segment Phex will merge it with the other segments of the file. This results in a much higher download speed. If a host is too slow the segment is split during download and given to an another host. To make sure you never run out of hosts Phex is able to find new download hosts by itself with the automatic search functionality.
Advanced configuration options
- Phex offers very advanced configuration options. Much more then many other clients can offer. Especially advanced user can configure Phex according to there needs and are able to tune and see the effect of different settings.
Passive searching and snooping for files
- With the passive search functionality Phex is able to constantly monitor the traffic that goes through the network and collect search results that match your passive search term. Also Phex snoops the traffic for new download candidates you need to finish your downloads faster. This type of searching is usefull for longtime monitoring of available files on the network.
Other features include:
- Multiple searches.
- Ultrapeer and compression technology for reduced bandwidth.
- Integrated chat.
- Browse host support.
- Bitzi metadata lookup.
- MAGMA support.
Enhancements:
- The GUI received many smaller improvements and a multitude of lesser and bigger changes happened under the hood.
- Download-side THEX integration was added, so poisoned files are no longer possible.
- The upload architecture was redesigned and a far leaner security system is used for better performance and a vastly reduced memory footprint.
- Many bugs were fixed.

OpenVPN is a full-featured SSL VPN solution which can accomodate a wide range of configurations, including remote access, site-to-site VPNs, WiFi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls (articles) (examples) (security overview) (non-english languages).
OpenVPN implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or 2-factor authentication, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface.
OpenVPN is not a web application proxy and does not operate through a web browser.
Enhancements:
- Fixed regression bug in Win32 installer, introduced in 2.0.1, which incorrectly set OpenVPN service to autostart.
- Dont package source code zip file in Windows installer in order to reduce the size of the installer. The source zip file can always be downloaded separately if needed.
- Fixed bug in route.c in FreeBSD, Darwin, OpenBSD and NetBSD version of get_default_gateway. Allocated socket for route manipulation is never freed so number of mbufs continuously grow and exhaust system resources after a while.
- Fixed bug where "--proto tcp-server --mode p2p --management host port" would cause the management port to not respond until the OpenVPN peer connects.
- Modified pkitool script to be /bin/sh compatible

iPirate project is a small application for sharing files between two friends.

iPirate was written in a day because I wanted to download some songs from a friend of mine, whose internet connection does not allow connections from internet to his machine (so FTP and friends are out).

I also did not want to use any established P2P software, because this is just a small and private sharing of files. Furthermore, I found it fun to code such a program.

The features include sharing your files, search for files containg a string, listing a users files and downloading files from a user.

Due to the circumstances that lead to the writing of this software, the program supports two modes of download: you either connect to the machine you want to download stuff from and say: start sending data, or you let the remote machine connect to your machine and receive the given data.

AMI provides a full P2P network.

AMI is a universal P2P framework written in Java and XML. It allows people to communicate using plug-in AMI protocols. It can support any P2P protocol.
