{{wrongtitle|title=konspire2b}}

'''konspire2b''' is a [[peer-to-peer]] network designed and implemented by [[Jason Rohrer]]. [[Client (computing)|Client]]s/[[node (networking)|node]]s can subscribe to channels and receive all incoming [[Computer file|file]]s from the channels they are subscribed to. Broadcasters can create channels and broadcast files to all the subscribers. 

This makes konspire2b markedly different from traditional [[file sharing]] software, where users search for files on connected systems. Instead, a konspire2b user is encouraged to simply subscribe to some channels of interest, let the software run for a few hours, and then look at the files they have received.

== Technical aspects ==

Any konspire2b user can create new channels. In order to broadcast files in a channel, a user needs to possess its [[private key]]. This private key can be shared among several users to allow for collaboratively run channels.

There is currently a single client implementation called '''kast'''.  It uses a browser-based [[user interface]]. In its present implementation, konspire2b suffers from high protocol overhead for the broadcasting of "announcement" messages for files.

All konspire2b-related software is [[open source]] under the [[GNU GPL]]. The konspire2b website uses a [[wiki]] for the purpose of documentation and [[brainstorming]].

== History ==

konspire2b succeeds the now defunct ''konspire'' network, a more traditional file client/server based file sharing application written in [[Java programming language|Java]]. Developer Jason Rohrer emphasizes that konspire2b  was written in C++ instead.

From [[2003]] onwards, the computer used to run ''katcher'' which informs Kast nodes of each others' existence, has not responded to queries.  Any computer can perform this task, preferably one with a static IP address, and there are some possibilities listed below.

There has been a continuing [[spamming]] campaign on the [http://konspire.sourceforge.net/cgi-bin/wiki.pl?main_page Konspire wiki], as a result, some information has been copied to this page where it can be kept in better condition.

Current systems running a katcher:
* katcher.2y.net : 6085
* nepp.dyndns.org : 6085
* kast.homedns.org : 6085

Another possibility is to add a connection via the webinterface to the kast client on nepp.dyndns.org:7085.
