B/c ipv6 of Tor implements currently no DirPort I copied+pasted together the following solution to deliver a Tor exit notice over HTTP port of ipv6 too :


The python snippet runs under a non-privileged user w/o login shell :


$ cat ipv6-httpd.py
import socket
from BaseHTTPServer import HTTPServer
from SimpleHTTPServer import SimpleHTTPRequestHandler

class MyHandler(SimpleHTTPRequestHandler):
  def do_GET(self):
    return SimpleHTTPRequestHandler.do_GET(self)

class HTTPServerV6(HTTPServer):
  address_family = socket.AF_INET6

def main():
  server = HTTPServerV6(('::', 8181), MyHandler)
  server.serve_forever()

if __name__ == '__main__':
  main()



The ip6table rules to redirect fort 80 from outside to the local non-privileged port :

  from=80
  to=8181
  $IPT -t nat -A PREROUTING -i enp3s0 -p tcp -m tcp --destination-port $from -j REDIRECT --to-ports $to
  $IPT -A INPUT -p tcp -m tcp --destination-port $to -j ACCEPT



And finally the script to start it during boot :


$> cat /home/simplehttp/ipv6-httpd.sh
#!/bin/sh
#

d=$(mktemp -d /tmp/XXXXXX)                        	&&\
cd $d                                                   &&\
cp /etc/tor/tor-exit-notice_DE.html ./index.html        &&\
nice python ~/ipv6-httpd.py 1>./log 2>&1
