Connection resolver chokes on UDP connections, on OS X 10.6.8
A default arm installation doesn't show me any connections, and gives me the error message as well:
We were unable to use any of your system's resolvers to get tor's connections. This is fine, but means that the connections page will be empty. This is usually permissions related so if you would like to fix this then run arm with the same user as tor (ie, "sudo -u <tor user> arm").
Here is the log line:
2/1/2012 19:54:42 [DEBUG] system call: lsof -wnPi | egrep "^tor *26419.*((UDP.*)|(\(ESTABLISHED\)))" (runtime: 0.02)
I fixed it by replacing the LSOF command, using the attached patch.
