That's strange. The return codes seem to imply that the requests are timing out, rather than there being a permissions problem:

When you say the "stock debian desktop", what is running at that point, something like Gnome, Xfce or LXDE?

If possible, it would be good to do the test on a text-mode console, with nothing else running.
