Previously, I've run arm using 'sudo -u debian-tor arm'. As was mentioned here previously, this is not how you should run it - in fact there is a bit of documentation to suggest how it should be done.
Yep. See https://trac.torproject.org/projects/tor/ticket/10700 for the discussion.
Unfortunately I'm having some issues getting arm working correctly as described here in step 14:
https://www.torproject.org/docs/tor-relay-debian.html.en#after
Having added my user (pi) to the debian-tor group, I try to run 'arm' and get the following:
Failed to read authentication cookie (permission denied): /var/run/tor/control.authcookie
What Tor version are you using? There was a bug in Tor 0.2.5.1-alpha through 0.2.5.6-alpha that broke cookie auth for this situation: https://trac.torproject.org/projects/tor/ticket/12864 It is fixed in 0.2.5.7-rc.
I've tried reinstalling arm, relogged and checked that I'm in the right group still using 'groups' (which I am) - no joy.
CookieAuthentication wasn't initially enabled, turning it on makes no difference, I get the same error.
As Grace pointed out, torrc isn't the only config file that your Tor deb uses.
Am I missing something when it comes to setting up CookieAuthentication? I guess I must be...although it seems strange that I was getting that error even with CookieAuthentication disabled.
If the Tor version hint doesn't do it for you, I'm not sure what the next step is. Hopefully it does. :)
