Bind livestatus unix socket to TCP socket use Python and twisted

from twisted.internet import protocol, reactor
import socket,os

socket_path = "/var/lib/nagios3/rw/live"

class Echo(protocol.Protocol):
    def dataReceived(self, data):
 s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)

 s.connect(socket_path)

 s.send(data)
 s.shutdown(socket.SHUT_WR)
 answer = s.recv(100000000)
        self.transport.write(answer)

class EchoFactory(protocol.Factory):
    def buildProtocol(self, addr):
        return Echo()

reactor.listenTCP(6557, EchoFactory())
reactor.run()
