Tor Stem - To Russia With Love Connection Issues

Question

I am trying to get the To Russia With Love tutoial from the Stem project working.

from io import StringIO
import socket
import urllib3
import time

import socks  # SocksiPy module
import stem.process

from stem.util import term

SOCKS_PORT = 9150

# Set socks proxy and wrap the urllib module

socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, '127.0.0.1', SOCKS_PORT)
socket.socket = socks.socksocket

# Perform DNS resolution through the socket

def getaddrinfo(*args):
  return [(socket.AF_INET, socket.SOCK_STREAM, 6, '', (args[0], args[1]))]

socket.getaddrinfo = getaddrinfo


def query(url):
  """
  Uses urllib to fetch a site using SocksiPy for Tor over the SOCKS_PORT.
  """

  try:
    return urllib3.urlopen(url).read()
  except:
    return "Unable to reach %s" % url


# Start an instance of Tor configured to only exit through Russia. This prints
# Tor's bootstrap information as it starts. Note that this likely will not
# work if you have another Tor instance running.

def print_bootstrap_lines(line):
  if "Bootstrapped " in line:
    print (term.format(line, term.Color.BLUE))


print (term.format("Starting Tor:\n", term.Attr.BOLD))

tor_process = stem.process.launch_tor_with_config(
  tor_cmd = "C:\Tor Browser\Browser\TorBrowser\Tor\\tor.exe", config = {
    'SocksPort': str(SOCKS_PORT),
#    'ExitNodes': '{ru}',
  }, 
  init_msg_handler = print_bootstrap_lines,
)

print (term.format("\nChecking our endpoint:\n", term.Attr.BOLD))
print (term.format(query("https://www.atagar.com/echo.php"), term.Color.BLUE))

tor_process.kill()  # stops tor

I have tweaked it a bit from the original to get it working with python 3.4 and I am also using pysocks instead of socksipy. I started with urllib instead of urllib3 and I had the same issue. Currently I am getting:

C:\Python>python program1.py
←[1mStarting Tor:
←[0m
←[34mFeb 28 21:59:45.000 [notice] Bootstrapped 0%: Starting←[0m

←[1m
Checking our endpoint:
←[0m
←[34mUnable to reach https://www.atagar.com/echo.php←[0m

I have had similar code work outside of tor. I can connect my tor browser to this site and I can browse to it with no problems. I have tried changing the port numbers, but this is the one that is set up in Tor's proxy settings. One thought I had is that this may be a timing issue. Is it possible that the code is not waiting long enough to the site to respond?

Any help in getting this working would be greatly appreciated.

Here's a working version of the stem tutorial that uses pysocks and its sockshandler module to avoid monkey-patching the socket module:

#!/usr/bin/env python
"""
https://stem.torproject.org/tutorials/to_russia_with_love.html

Usage:
  russian-tor-exit-node [<tor>] [--color] [--geoipfile=</path/to/file>]
  russian-tor-exit-node -h | --help
  russion-tor-exit-node --version

Dependencies:

- tor (packaged and standalone executables work)
- pip install stem
- pip install PySocks
- pip install docopt
  : parse options
- pip install colorama
  : cross-platform support for ANSI colors
- [optional] sudo apt-get tor-geoipdb
  : if tor is bundled without geoip files; --geoipfile=/usr/share/tor/geoip
"""
import sys
from contextlib import closing

import colorama  # $ pip install colorama
import docopt  # $ pip install docopt
import socks  # $ pip install PySocks
import stem.process  # $ pip install stem
from sockshandler import SocksiPyHandler  # see pysocks repository
from stem.util import term

try:
    import urllib2
except ImportError: # Python 3
    import urllib.request as urllib2


args = docopt.docopt(__doc__, version='0.2')
colorama.init(strip=not (sys.stdout.isatty() or args['--color']))

tor_cmd = args['<tor>'] or 'tor'
socks_port = 7000
config = dict(SocksPort=str(socks_port), ExitNodes='{ru}')
if args['--geoipfile']:
    config.update(GeoIPFile=args['--geoipfile'], GeoIPv6File=args['--geoipfile']+'6')


def query(url, opener=urllib2.build_opener(
        SocksiPyHandler(socks.PROXY_TYPE_SOCKS5, "localhost", socks_port))):
  try:
      with closing(opener.open(url)) as r:
          return r.read().decode('ascii')
  except EnvironmentError as e:
    return "Unable to reach %s: %s" % (url, e)

# Start an instance of Tor configured to only exit through Russia. This prints
# Tor's bootstrap information as it starts. Note that this likely will not
# work if you have another Tor instance running.
def print_bootstrap_lines(line):
  if "Bootstrapped " in line:
    print(term.format(line, term.Color.BLUE))
  else:
    print(line)

print(term.format("Starting Tor:\n", term.Attr.BOLD))
tor_process = stem.process.launch_tor_with_config(
    tor_cmd=tor_cmd,
    config=config,
    init_msg_handler=print_bootstrap_lines,
)
try:
    print(term.format("\nChecking our endpoint:\n", term.Attr.BOLD))
    print(term.format(query("https://icanhazip.com"), term.Color.BLUE))
finally:
    if tor_process.poll() is None: # still running
        tor_process.terminate()  # stops tor
        tor_process.wait()

It works on both Python 2 and 3 on my Ubuntu machine.

strace shows data and dns requests are made via the tor proxy.
