Torify Torrentflux-b4rt

In my quest to anonymize all traffic leaving my home network, I ran into the problem of torifying my bittorrent transfers. Routing the actual transfers through Tor would be far too slow so I will be showing you how to anonymize only the tracker requests. But remember, pirating is bad mmmkay.

Torrentflux-b4rt is a web based transfer control client. Nothing is more convenient than starting a new download from anywhere, at anytime. Whether it be from a work computer, a friend’s computer, or a phone, having this installed on your server is a godsend.

Tor is a software project that helps you defend against traffic analysis. Though some consider the use of bittorrent over Tor to be counter to the goals of the Tor project, this article does not seek to answer the questions about the validity of any protocol over the Tor network but merely how to do it. Also, be aware that the BT protocol itself my reveal a nodes real IP. Be informed about the technologies you use.

Assuming you already have Torrentflux-b4rt installed and running.

• Install the Tor and Privoxy packages.
  sudo apt-get install tor privoxy
• Next, edit the Privoxy config file to forward requests to Tor
  sudo nano /etc/privoxy/config
• Uncomment or add the the following line in the Forwarding section:
  forward-socks4a/localhost:9050 .
• Save and close the file while remembering to restart the Privoxy service.
  sudo /etc/init.d/privoxy restart

Now to hack the BitTornado client used by Torrentflux-b4rt.

• Edit the following file located in the Torrentflux-b4rt directory:
  sudo nano /html/bin/clients/tornado/BitTornado/zurllib.py
• Add the following to the connect() method defined within the btHTTPcon class:

  self.host = '127.0.0.1'
  self.port = 8118
  

• The full class should read:

  class btHTTPcon(HTTPConnection):
  	def connect(self):
  		# proxy hack start
  		self.host = '127.0.0.1'
  		self.port = 8118
  		# proxy hack end
  		HTTPConnection.connect(self)
  		try:
  			self.sock.settimeout(30)
  		except:
  			pass
  

• Next, alter the following line in the _open() method defined within the urlopen class to read:

  self.connection.request('GET', scheme + '://' + netloc + url, None,
  	{ 'User-Agent': VERSION,
  	  'Accept-Encoding': 'gzip' } )
  

You can test if your trackers are being routed through Tor by uncommenting the logfile option in /etc/privoxy/config.
