I'm building an application that makes several user-specified internet connections; twisted meets my needs more or less perfectly.
I'm running into a problem, however, in that twisted is not allowing connections (reactor.connectTCP) by hostname, only IP address. [read: connections to IP addresses work fine, hostnames no] From what I can tell, the problem lies in that Twisted simply isn't performing the DNS resolutions. From the connection factory's startedConnecting method, print connector.getDestination() results in: IPv4Address(TCP, 'hostname', port) That is to say, the port is correct, but the 'hostname' is completely unresolved. Since 'hostname' is a really bad IP address, not being one at all, the connection of course fails. A check via tcpdump on my gateway machine shows that the DNS resolution doesn't occur. The API documentation for version 1.3 (I'm using 2.0.1, but a quick check of twisted source/docstrings shows this to be still true[1]) shows that connectTCP taks "a host name," so by that (and the echo client example that connects to 'localhost') I presume there's supposed to be some sort of resolution going on. I'm running twisted 2.0.1 on win32. Is this a bug in twisted, or is there some configuration that I've gone and borked? [1] -- is there some reason in particular that there's no API reference for twisted 2.0x? The documentation/tutorials are pretty sparse as-is, I think. -- http://mail.python.org/mailman/listinfo/python-list
