I’ve bumped into a weird one, and can’t figure out what I’m missing.
for iface in interfaces:
for port in ports:
logger.debug("Listening on {}:{}".format(iface, port))
if use_ssl:
reactor.listenSSL(port, factory,
ssl.DefaultOpenSSLContextFactory(ssl_key, ssl_cert),
interface=iface)
else:
reactor.listenTCP(port, factory, interface=iface)
In the above code block, listenSSL() and listenTCP() both fail silently. They
do not raise an exception, and netstat reports nothing listening on the
appropriate port.
Even weirder, if I assign the results of listenSSL() and listenTCP(), then then
a v6 connection will succeed but v4 still fails (silently).
I get the same behaviour for both (so, regardless of the value of use_ssl in
this code).
for iface in interfaces:
for port in ports:
logger.debug("Listening on {}:{}".format(iface, port))
if use_ssl:
connector = reactor.listenSSL(port, factory,
ssl.DefaultOpenSSLContextFactory(ssl_key, ssl_cert),
interface=iface)
else:
connector = reactor.listenTCP(port, factory, interface=iface)
logger.debug( "Connected with connector: {}".format(connector))
logger.debug( "Connector on host {}".format(connector.getHost()))

I’ve used this exact recipe before without any trouble (the first block, with
unassigned results from reactor.listen*).. I can’t figure out what I’m missing
this time. Does anything stand out to anyone?
Using py27-twisted-13.2.0 port on FreeBSD 9.2.
