Twisted : How to know which client has closed the connection

Question

This is a follow-up to my previous question.

I am building a simple client server program using ´twisted´ package in Python.

I would like to keep a record of which client has joined and closed the connection.

Suppose, if Client B closes the connection, I would like to print at the server "Client B has closed the connection"

Here is the code I am using :

factory = protocol.ServerFactory()
factory.protocol = Echo
PortNo = 8000
reactor.listenTCP(PortNo,factory)

reactor.run()



def connectionLost(self, reason): 

print "Connection lost" 

Any idea how to do it ?

Thanks

Answer 1

The connection which was lost is the one associated with the protocol instance referenced by the self argument to connectionLost.

With a normal factory (like ServerFactory, as you are using) there is a one to one relationship between connections and protocol instances.
