Kademlia in Python

Installation

pip install kademlia

Usage

This assumes you have a working familiarity with Twisted.

Assuming you want to connect to an existing network (run the standalone server example below if you don't have a network):

from twisted.internet import reactor
from twisted.python import log
from kademlia.network import Server
import sys

# log to std out
log.startLogging(sys.stdout)

def quit(result):
    print "Key result:", result
    reactor.stop()

def get(result, server):
    reactor.stop()
    #return server.get("a key").addCallback(quit)

def done(found, server):
    log.msg("Found nodes: %s" % found)
    return server.set("a key", "a value").addCallback(get, server)

server = Server()
# next line, or use reactor.listenUDP(5678, server)
server.listen(5678)
server.bootstrap([('127.0.0.1', 1234)]).addCallback(done, two)

reactor.run()

Stand-alone Server

If all you want to do is run a local server, just start the example server:

twistd -noy server.tac
