__doc__ = """Connection Resolution
Connection information is a useful tool for learning more about network
applications like Tor. Our stem.util.connection.get_connections() function
provides an easy method for accessing this information, with a few caveats...
Connection resolvers are platform specific. We support several platforms but
not all.
By default Tor runs with a feature called DisableDebuggerAttachment. This
prevents debugging applications like gdb from analyzing Tor unless it is run as
root. Unfortunately this also alters the permissions of the Tor process /proc
contents breaking numerous system tools (including our resolvers). To use this
function you need to either run as root (discouraged) or add
DisableDebuggerAttachment 0 to your torrc.
Please note that if you operate an exit relay it is highly discouraged for you
to look at or record this information. Not only is doing so eavesdropping, but
likely also a violation of wiretap laws.
With that out of the way, how do you look up this information? Below is a
simple script that dumps Tor's present connections.

== stem_examples tor testing ==
This is a Python doctest file that is executable documentation.
stem_examples is a set of small scripts that tell you about your
running tor instance.
Pass the controller password if needed as an environment variable:
Onionoo is a web-based protocol to learn about currently running Tor
relays and bridges. Onionoo itself was not designed as a service for
human beings---at least not directly. Onionoo provides the data for
other applications and websites which in turn present Tor network
status information to humans: https://metrics.torproject.org/onionoo.html
You can see the status of tor relays at https://torstatus.rueckgr.at/
The code for that site is at https://github.com/paulchen/torstatus
You can get a list of exit relays that are marked bad with:
wget --post-data='SR=FBadExit&SO=Asc&FBadExit=1' 'https://torstatus.rueckgr.at/'
It is assumed that you are running a tor that has its torrc configured with:
ControlPort 127.0.0.1:9051
and/or
ControlSocket /run/tor/control
ControlSocketsGroupWritable 1
We can authenticate with a password. To set a password first get its hash...
% tor --hash-password "my_password"
16:E600ADC1B52C80BB6022A0E999A7734571A451EB6AE50FED489B72E3DF
and use that for the HashedControlPassword in your torrc.
HashedControlPassword 16:E600ADC1B52C80BB6022A0E999A7734571A451EB6AE50FED489B72E3DF
so that you have some security on the Control connection.
Pass the controller password to these scripts as an environment variable:
>>> import os
>>> assert os.environ['TOR_CONTROLLER_PASSWORD']
If you are using /run/tor/control you will also need to run the scripts as the user
that has rw access to that socket, usually tor or debian-tor.
Add our code to the PYTHONPATH
>>> import sys
>>> sys.path.append(os.path.join(os.getcwd(), 'src', 'stem_examples'))
We'll need the settings defined in {{{/usr/local/etc/testforge/testforge.yml}}}
We'll used the settings defined in {{{/usr/local/etc/testforge/testforge.yml}}}
If you don't have one, make it with the settings from your torrc:
>>> print("yaml", file=sys.stderr)
>>> import yaml
>>> sFacts = open('/usr/local/etc/testforge/testforge.yml').read()
>>> assert sFacts
>>> dFacts = yaml.safe_load(sFacts)
