</span>Yep. See <a href="https://trac.torproject.org/projects/tor/ticket/10700" target="_blank">https://trac.torproject.org/projects/tor/ticket/10700</a><br>

</span>What Tor version are you using? There was a bug in Tor 0.2.5.1-alpha<br>
through 0.2.5.6-alpha that broke cookie auth for this situation:<br>
<a href="https://trac.torproject.org/projects/tor/ticket/12864" target="_blank">https://trac.torproject.org/projects/tor/ticket/12864</a><br>
It is fixed in 0.2.5.7-rc.<br>

</span>As Grace pointed out, torrc isn't the only config file that your<br>
Tor deb uses.<br>

</span>If the Tor version hint doesn't do it for you, I'm not sure what the<br>
next step is. Hopefully it does. :)<br>
