Free peer to peer software for linux

PeerProtect is an addon for Jays firewall that generates a file which contains all IP addresses from the RIAA and MPAA, etc. and will protect peer-to-peer programs from them. The Database can be copied from PEERGUARDIAN or IPPREFIX.

KoffeePhoto is a free software that allows you to manage your personal photo library. You can manage your photo albums with KoffeePhoto, and share them with your friends or family very easily. Your albums will be saved on the KoffeePhoto network, which will let you access them anytime and anywhere.

KoffeePhoto allows you to pick your photos on your hard disk or on your camera, and to organize them in albums. Thanks to several ways of sorting your photos, by date, topic, place, person, or any combination of these categories, you will always have an easy way to find all your photos again.

KoffeePhoto saves your whole photo library on its peer-to-peer KoffeePhoto network. This is carried out in a completely seamless way. Your photos are encrypted to ensure confidentiality, and are saved without any loss in quality (no format reduction, no data compression), and no storage expiration date. You can access your photo library from several computers if you wish. In case of any data loss, you can recover your whole photo library very easily!

ZMsgServer is a peer-to-peer LAN messaging application written in the Java programming language. I have successfully tested the application on a variety of platforms, under a variety of network conditions, and even in its infancy, it is a very nicely featured application. I use it regularly for sending "reminders" and code-snippets across the network to other machines. A fast and simple way to get a message to another user on the LAN.

Until I get some more comprehensive documentation online, here is a brief overview of how ZMsgServer works. Each machine on the LAN runs an instance of the server, listening on port 7999. If you have another service on your network that uses port 7999, then change the source to a free port. Ill make this configurable via the GUI in a later version.

When another host wants sends a message, it uses the next available port to broadcast the message, which is received via port 7999 on the recipient machine. Messages are sent via an ObjectOutputStream and are instances of the ZMessage class, which is nothing more than a nice neat container for four strings. These messages are received on the targets machine, decomposed, and displayed on the GUI.

When the documentation is online, all will become clear, but for now, download the source code below, as its the best documentation available!

rstudio project is a GTK+ GUI that controls programs used in recording, CD mastering, and managing a SHOUTcast server.
The "Radio Station" referred to here is a Shoutcast server. Before you can play any music on the station, you need to either record your own, or use a Peer-to-Peer program or other source to download some music.
The GTK-Gnutella button starts a peer to peer fileshareing program called GTK-Gnutella where you can get a wide variety of music free.
Start Radio station starts up the shoutcast server and its source client, which feeds an mp3 playlist to the server for broadcast.
The playlist file is created when you press the "Close" button in the playlist manager. The playlist manager lets you view either the downloaded files from GTK-Gnutella, or the permanent collection of files. You can select a file, then move it to the permanent collection, only if you are viewing the downloaded files. For either set, you may delete a file, or play it.
Audacity is a very versatile recording tool that can be used to create original content, or to record from other sources, such as a Shoutcast.com station, (or even your own shoutcast station).
Shoutcast.com button starts firefox, with the url of http://www.shoutcast.com so that you may listen to other shoutcast stations, or your own.
Kill XMMS stops any running xmms.
Quit exits rstudio.
GTK-Gnutella starts the P-2-P filesharing system.
K3B can be used to master audio CDs, or even mp3 data CDs that can be played on an mp3-compatible cd player or dvd player.
Enhancements:
- A shuffle playlist button was added.
- The audio player was changed to Audacious since Gentoo does not support XMMS.
- This version was tested on Gentoo AMD64 and Kubuntu 386.

Speextalk is a simple, yet powerful voice-over-IP (VoIP) program with a custom protocol using the Speex codec.
The keyword is simple: Speextalk does VoIP, and only VoIP, but the protocol is simple, the code is simple, and the usage is simple for an average Unix user.
Main features:
- Direct peer to peer two persons discussion.
- Low to very low bandwidth usage (can be less than 1.2ko/s).
- Identification of the callee by its IP address or host name and optionaly port number.
- Network protocol independant code (IPv6 is supported, IPv8 would be).
- Text mode interface.
Enhancements:
- Initial ChangeLog creation. Supported features: ALSA sound output, text-mode interface, Speex mono low, wide and ultra-wide band.

P2P-Radio provides a peer-to-peer audio and video broadcasting system.
P2P-Radio is a peer-to-peer audio (MP3) and video (NSV) broadcasting system that features freeloader detection, stream signing, SHOUTcast support, an easy-to-use GUI, and a separate monitor application which displays the current structure of the P2P network.
P2P-Radio is programmed in Java and runs on Windows, Mac OS X, Linux and many other systems.
Main features:
- Easy to use (graphical user interface)
- You can play the music/video with your media player (i.e. Winamp)
- A Shoutcast/Icecast Internet radio/TV station is used as audio/video source
- Freeloaders (peers that only listen but dont want to send the stream to other listeners) will be detected
- The data stream is signed, you can be sure that it arrives unchanged
- Very efficient communication (low overhead)
- The network structure can be viewed with a monitor
Enhancements:
- Signing of streams has been turned off by default in order to save CPU time (enable it with the parameter "-sign")
- P2P-Radio will only cooperate with a monitor if it was started with the parameter "-enablemonitor"
- Two parameters control whether the media player will be started:
- startmediaplayer: Start the media player in broadcasting mode
- dontstartmediaplayer: Dont start the media player in listening mode

Lopster is a file-sharing client that supports napster-like server such as OpenNap or SlavaNap.
Napster is a protocol for sharing files between users. With Napster, the files stay on the client machine, never passing through the server. The server provides the ability to search for particular files and initiate a direct transfer between the clients. In addition, chat forums similar to IRC are available
Main features:
- compression support for server-client communication (opennap-ng)
- autoconnect to server and channels
- external event handling for a few events (calling external script)
- support of all opennap commands
- basic IRC support
- statistic for current transfers and file accesses
- multi source downloads and autoresume
- bandwidth limitation per transfer and user
- user priority classes for uploads
- search on Napster, in Library, in Browses and Search Results
- notification when hotlist users are on
- display filters for browses
- quick search in browse
- libraries are save/load-able
- quick search in your library
- opennap channel operator extension support
- colors scheme support
- highlightet text for special words and friend users
