By default localhost any localhost connnection should be allowed through
with ubuntu iptables AFAIK, but as a test just try stopping iptables, trying
your samples, then start it again. Make sure that you have an example where
one side is calling bind() and the other connect() as well, if you've
tweaked the code at all.
