Free p2p software software for linux

p2pshaper is a Linux QoS script to ensure good latency and fairness on a slow network connection overloaded by p2p applications. It also includes generic optimizations to improve fairness. This release includes a large number of improvements since the 1.3 test release.
In short p2pshaper is a set of scripts for the Linux OS, that is used to administer bandwidth on a network overloaded by massive p2p traffic.
Normally, the amount of peer-to-peer traffic on such networks, will make it impossible to surf, not to mention doing interactive traffic (ssh). The normal action is to shut down p2p traffic totally, and set up the net, so that Internet connection is only possible through a proxy. This breaks many useful programs. And not all p2p traffic is evil. Normally, one would mark packets coming to a specific port (emule ports) to be of a lower priority than packets to other ports. This used to be a good solution. But now, there exist a huge number of p2p clients, eact with different port ranges, and also, some programs are able to change the ports. Normally the Internet newsgroup port should have a high priority. But binary newsgroups are sometimes used for massive downloads, which will use up all bandwidth. Better packet markers are needed.
p2pshaper currently exists in two versions p2pshaper v1 and p2pshaper v2. They both works in different ways, so v2 is not "better" than v1. Which one you use depends on what kind of functonality you want.
Enhancements:
- Added unified patches against recent kernels With the amount of patches p2pshaper needs, people have had problems patching kernels. To make this easier, p2pshaper now includes patches for most recent kernels. This will probably ease the installation of
- p2pshaper. Old patches have been moved to the old/ directory.
- Normal connections will never get into the lowest priority bandIntroduced already in the 1.4.1 release. This makes sure that normal traffic isnt nuked all the way into oblivion, where only evil traffic (marked by l7_filter, ipp2p or band8ports) should be.

FTwall is short for Fast Track traffic Firewall, a P2P traffic filtering script, for Kazaa blocking.
Ftwall-2 is an updated version of the original ftwall-1 software which adds new P2p protocols to the set it can control.
Ftwall-2 is an add-on for linux firewalls that allows the control of "Fast Track" peer-to-peer traffic (such as is used by "Kazaa" and its derivatives), WinMX and others using the OpenNAP protocol.
It is designed to block network traffic from P2P client applications running in the "home" (or "green") network from making access to any peers on the public internet. It is designed primarily for use in networks where the security reigme allows "open access" for outbound connections and "tightly limited" access for inbound ones. Ftwall-2 can be used in networks like this to prevent outbound P2P access from the supported protocols, hence restricting illegal file downloads and uploads.
A Fast track "home network" client that establishes an "outbound" connection is (worryingly) immediately available to accept inbound connections through the established TCP/IP socket - even if the gateway firewall blocks all in-bound connections via "normal" TCP/IP and UDP mechanisms. This is a kind of limited "tunnelling" and gives rise to a number of concerns. Other P2P applications and protocols present similar security challenges. Ftwall solves this (and other) problems for the protocols it understands.
Version 1 of ftwall controlled the Fast Track protocol only (Kazaa et al).
Version 2 of ftwall (the version discussed on this page) adds logic to allow blocking of traffic from WinMX and OpenNap clients using a mechanism based on DNS name wildcards. One simple example is the control of WinMXs native protocol which can be blocked by preventing access to IP addresses resolved from any domain name that ends "winmx.com". OpenNAP is similarly controlled using DNS wildcards to "train" ftwall. See the man page (etc) for these new features by following the links at the bottom of the page.
FTwall-2 runs on Linux-based firewalls using kernel 2.4 (tested with 2.4.20) or later and iptables (test with version 1.2.6). This combination of version numbers is the current set employed by RedHat 8.0 - which is the system on which the software has been developed. The software has also been tested briefly on RedHat 9 and Fedora - but I am awaiting more in-depth news of these and other Linux distributions.
FTwall-2 runs well on the "ipcop" firewall, version 1.3.0 (GPL) with the QUEUE target and string match modules added manually. I believe that it will similarly run on Smoothwall 2 (GPL) although I have not tested this. It will NOT run on Smoothwall 1.0 since this is an "ipchains" based firewall, not an "iptables" one.
FTwall-2 has been tested with the following P2P client applications:
Kazaa 2.1.1, 2.5-beta2, 2.5.1
Kazaa Lite 2.0.2, K++ 2.4.3
iMesh 4.1 build 132, 4.2 build 138
Grokster 1.7
WinMX 3.31
Version restrictions:
- Ftwall requires Linux kernel version 2.4, equipped with "iptables" and the "QUEUE" target. The "ip_string" match module of iptables is desirable, but not required.
- Ftwall works with the "current" version of the Fast track, WinMX and OpenNAP network protocols at the time of writing (July 2004). It is possible that it will need to be re-worked if the protocols are changed in future.
- Ftwall does not block the "SOCKS PROXY" connection option of FastTrack. For a complete lock-down, the firewall must block this style of traffic.

Hybrid Share is a User Friendly Application for Linux, Mac and Windows users, that allow you to Share file (and Talk) instantly with your friends...

What is Hybrid Share ?

Hybrid Share is a simple (User Friendly) Mono C#/Gtk# Application that allow Mac, Windows and Linux Users To Share Files. The Application is extensible via Plugins, so you can Talk with connected people, check your mailbox or other things that plugins could do.

What do you use if you have to share files with your friends ?

E-Mail or Instant Messaging are the first possible solution, but the E-Mail Size block and the slowing of the IM make this channels bad to share files. The NFS (Network File System) or other system like this, works only between similar system or are a little bit difficoult to configure, the same for ftp server.

So The Solution is Hybrid Share that is Portable and Easy to Use, It isnt the Best Application in The World, but it does a useful work.

What is the Difference with a Normal P2P ?

Hybrid Share has a core of P2P but is more like a traditional IM (Instant Messenger), like GTalk, MSN, Gaim, Adium and so on.... No Network Configuration is needed, Youve only to add your "buddies" (like an IM) and Drag File Into their folders...

Stream-2-Stream project (abbreviated "s2s" or "S2S") allows anyone with a normal broadband connection to set up their own radio station or internet television, for free.
Stream-2-Stream stations have no user limit; stations can be set up without paying a fortune for bandwidth. Stream-2-Stream saves bandwidth by passing streams from one peer to another, rather than everyone getting a stream from one central server (Shoutcast/Icecast).
Supported codecs are MP3, NSV, and Ogg Vorbis.
Main features:
- Integrated MP3, Ogg media player. No external media player needed to listen!!!
- Easy to use GUI
- Bandwidth is tested automatically for the best p2p streaming performance
- Settings are saved to xml
- Easy to use server command-line
- A shoutcast/icecast internet radio/TV Station is used as the source
- Freeloaders/Leechers (peers that only listen but dont want to send out the stream to other listeners) will be detected
- The data stream can be signed; you can be sure that it arrives unchanged
- Very efficient communication (low overhead).
- The network structure can be viewed with a monitor
- Peers can be denied service
- Streams can be recorded to files for later viewing
Enhancements:
