AuthenticatingTelnetProtocol requires an argument to its constructor - the cred portal to use to do the authentication and authorization with. However, ServerFactory.buildProtocol doesn't invoke it with any arguments, so you get a TypeError. You can fix this by making your factory's protocol be a no-argument callable instead - eg, by making it a lambda that closes over the portal or the factory: def __init__(self, portal): self.protocol = lambda: AuthenticatingTelnetProtocol(portal) However, this won't completely fix your problems. AuthenticatingTelnetProtocol expects to be connected to an ITelnetTransport, not an ITCPTransport. http://twistedmatrix.com/trac/browser/branches/telnet-server- example-3940/doc/conch/examples/telnet_echo.tac might help illuminate the way telnet transports and telnet protocols are intended to be assembled.
