== 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.

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 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
    >>> try:
    ...     sFacts = open('/usr/local/etc/testforge/testforge.yml').read()
    ...     assert sFacts, sFacts 
    ... except:
    ...     dFacts = dict(
    ...       HTTPS_PROXYHOST="127.0.0.1",
    ...       HTTPS_PROXYPORT=9128,
    ...       HTTPS_PROXYTYPE="http",
    ...       SOCKS_PROXYHOST="127.0.0.1",
    ...       SOCKS_PROXYPORT=9050,
    ...       SOCKS_PROXYTYPE="socks5",
    ...     )
    ... else:
    ...     dFacts = yaml.safe_load(sFacts)

 
FixMe: use the settings for the ports and directories below.

    >>> import os
    >>> os.environ['https_proxy'] = 'http://'+dFacts['HTTPS_PROXYHOST']+':'+str(dFacts['HTTPS_PROXYPORT'])
    >>> os.environ['socks_proxy']  = 'socks5://'+dFacts['SOCKS_PROXYHOST']+':'+str(dFacts['SOCKS_PROXYPORT'])

### compare_flags Comparing Directory Authority Flags
### introduction_points Introduction Points

    >>> print("introduction_points", file=sys.stderr)
    >>> import introduction_points

The introduction points are the ways of connecting to hidden services.
We test 3 known hidden services: Facebook, DuckDuckGo and .

   >>> lKNOWN_ONIONS = [
   ...  'facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd', # facebook
   ...  'duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad', # ddg
   ... ]

We wil expect to get back the hidden service version, the descriptor-lifetime
and then the descriptor-signing-key-cert:

    >>> introduction_points.iMain(lKNOWN_ONIONS) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
    0

### exit_used Determine The Exit You're Using

Lets say you're using Tor and one day you run into something odd. Maybe a
misconfigured relay, or maybe one that's being malicious.
How can you figure out what exit you're using?

    >>> print("exit_used", file=sys.stderr)
    >>> import exit_used
    >>> exit_used.iMain([])

## relay_connections Connection Summary

    >>> print("relay_connections", file=sys.stderr)
    >>> import relay_connections
    >>> relay_connections.iMain([]) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
    +------------------------------+------+------+
    ...
    +------------------------------+------+------+
    <BLANKLINE>

The following provides a summary of your relay's inbound and outbound connections.
You must be root or tor to run this:
relay_connections.iMain(["--ctrlport", "9051"])

## connection_resolution  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.

    >>> print("connection_resolution", file=sys.stderr)
    >>> import connection_resolution
    >>> connection_resolution.iMain([]) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
    0

## tor_bootstrap_check

    >>> print("tor_bootstrap_check", file=sys.stderr)
    >>> import tor_bootstrap_check

A script by adrelanos@riseup.net to check what percentage of boostrapping
tor is at. This fails under doctest but not from the cmdline

    >>> tor_bootstrap_check.iMain([]) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
    0

## check_digests

    >>> from check_digests import iMain
    >>> sKNOWN_ONION = 'facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd' # facebook
    >>> from stem_examples.introduction_points import lMain as lIPMain
    >>> lArgs = []
    >>> import stem_examples.support_testing as ts; with ts.ignoreStdout():
    ...    lArgs = lIPMain([sKNOWN_ONION])
    >>> iMain(lArgs)
    0
    
## interpreter

    >>> print("interpreter", file=sys.stderr)
    >>> import interpreter
    >>> lArgs = ['GETINFO', 'version']
    >>> interpreter.iMain(lArgs) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE

## outdated_relays List Outdated Relays

Time marches on. Tor makes new releases, and at some point needs to drop
support for old ones. Below is the script we used on ticket 9476 to reach out
to relay operators that needed to upgrade.

    >>> print("outdated_relays", file=sys.stderr)
    >>> import outdated_relays
    >>> outdated_relays.iMain([]) #doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
