It's function is to connect to a daemon, receive a line that's to be displayed to an end-user upon which the user should undertake some action. The action will trigger a second line (fail/success) at which point the daemon will close the connection. If, however, the end-user does not follow-up on the first challenge I want the script to timeout with a failed result. Now, I have the LineReceiver do exactly what I want, but I can't for the life of me understand how I should "wrap" it in the TimoutProtocol so that it disconnects after a couple of seconds? This is my Factory: class WebSSOFactory(ClientFactory): pamh = None client = None I think one problem here is that your WebSSOFactory is not a TimeoutFactory (https://twistedmatrix.com/documents/current/api/twisted.protocols.policies.T...). You have to pass a TimeoutFactory to the TimeoutProtocol in order for it to work with the LineReceiver you are wrapping, otherwise the timeout value will not be set; a regular Factory’s buildProtocol method would not know that it needs to pass the timeout to the TimeoutProtocol. Hope this helps, Daniel
