I apologize if this isn't the forum for Ceilometer questions.

I'm running the ceilometer test cases on Ubuntu 12.10. Most of the tests pass, but test_bin.BinApiTestCase fails when trying to connect to http://127.0.0.1:10695/v2/meters. Here's the command I'm running from /opt/stack/ceilometer:

tox -e py27,pep8

Here is the failure message:

I added the stdout to show the URL that is failing. I'm able to connect to the URL using lynx on the console.

A few things to note: I'm behind a proxy server, but I have configured httpproxy and httpsproxy to refer to the proxy. I've also configured no_proxy="localhost,127.0.0.1", and I've configured dconf's ignore-hosts to this:

['localhost', '127.0.0.0/8', '10.0.2.15', '.hpcloud.net', '.hpcloud.ms', '127.0.0.1']

Any ideas on why this connection is failing appreciated.
