The 'socket' attribute that you're accessing is not a documented attribute of ITransport, so in a way I'm glad that your code broke - this wasn't a valid way to use Twisted in the first place :). See <http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.ITransport.html>. Now, as it happens, <http://twistedmatrix.com/documents/current/api/twisted.protocols.tls.TLSMemoryBIOProtocol.html> implements <http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.ISSLTransport.html> which is a subinterface of <http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.ITCPTransport.html>, which is therefore guaranteed to have a getPeer method <http://twistedmatrix.com/documents/current/api/twisted.internet.interfaces.ITCPTransport.html#getPeer> that returns an IPv4Address <http://twistedmatrix.com/documents/current/api/twisted.internet.address.IPv4Address.html> or IPv6Address <http://twistedmatrix.com/documents/current/api/twisted.internet.address.IPv6Address.html>, both of which have a 'host' attribute that is the hostname. So, in short, substitute "self.transport.getPeer().host" and your code should work again. -glyph _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
