anchor.diff:  Linux: Stop the daemon version of the service and run it in verbose mode:
   ----
   $ sudo service grr stop
  -$ sudo /usr/sbin/grrd --config=/usr/lib/grr/grr_3.0.7.1_amd64/grrd.yaml --verbose
  +$ sudo /usr/sbin/grrd --config=/usr/lib/grr/grr_3.1.0.2_amd64/grrd.yaml --verbose
   ----
   
   OS X: Unload the service and run it in verbose mode:
   ----
   $ sudo launchctl unload /Library/LaunchDaemons/com.google.code.grr.plist
  -$ sudo /usr/local/lib/grr_3.0.7.1_amd64/grrd --config=/usr/local/lib/grr_3.0.7.1_amd64/grrd.yaml --verbose
  +$ sudo /usr/local/lib/grr_3.1.0.2_amd64/grrd --config=/usr/local/lib/grr_3.1.0.2_amd64/grrd.yaml --verbose
   ----
   
   Windows: The normal installer isn't a terminal app, so you don't get any output if you run it interactively. 
   
  -- Install the debug ``dbg_GRR_3.0.7.1_(amd64|i386).exe`` version to make it a terminal app.
  +- Install the debug ``dbg_GRR_3.1.0.2_(amd64|i386).exe`` version to make it a terminal app.
   - Stop the ``GRR Monitor`` service in task manager
   
   Then run in a terminal as Administrator
   ----
  -cd C:\Windows\System32\GRR\3.0.7.1\
  +cd C:\Windows\System32\GRR\3.1.0.2\
   GRR.exe --config=GRR.exe.yaml --verbose

positive.code: On linux and OS X you should see two processes, something like:
  ----
  $ ps aux | grep grr
  root       957  0.0  0.0  11792   944 ?        Ss   01:12   0:00 /usr/sbin/grrd --config=/usr/lib/grr/grr_3.0.7.1_amd64/grrd.yaml
  root      1015  0.2  2.4 750532 93532 ?        Sl   01:12   0:01 /usr/sbin/grrd --config=/usr/lib/grr/grr_3.0.7.1_amd64/grrd.yaml
  ----
  
  On windows you should see a ``GRR Monitor`` service and a ``GRR.exe`` process in taskmanager.
  
  If it isn't running check the install logs and other logs in the same directory:
  
  - Linux/OS X: ``/var/log/grr/grr_installer.txt``
  - Windows: ``C:\Windows\System32\LogFiles\GRR_installer.txt``
  
  and then try running it interactively as below.
  
negative.code: The URL here should be the server address and port you picked when you set up the server and listed in ``Client.control_urls`` in the client's config.
  ----
  wget http://yourgrrserver.yourcompany.com:8080/server.pem
  # Check your config settings, note that clients earlier than 3.1.0.2 used Client.control_urls
  $ sudo cat /usr/lib/grr/grr_3.1.0.2_amd64/grrd.yaml | grep Client.server_urls
  Client.server_urls: http://yourgrrserver.yourcompany.com:8080/
  ----
  
  If you can't download that server.pem, the common causes are that your server isn't running or there are firewalls in the way.
