Here's a python script for updating your tunnel. Please test it out.

[PatrickDickey]

Hi everyone,

I wrote a python script that can be run as either a cronjob (or Scheduled Task on Windows) or manually to update your tunnel. The way it's set up right now, you need to have a file in the same directory called "UserInfo.txt" which should have

UserID
Password (MD 5 Hash)
Tunnel ID
an IP Address to check against

It will write the results to a file called results.log in the same directory as well.  You can edit the script and enter your user information in the variables (and then remove the call to the ReadInformation() method), or create the file. I've tested it on Ubuntu 12.10 with Python 2.7.3, so if you'll let me know what your experiences are, I'll greatly appreciate it. Eventually I want to make a GUI version of the script (and a Python 3 version).

#!/usr/bin/env python

#Version: 0.2.2012-10-23
#Purpose: Intended to run as a cronjob or manually. It gets the information from the UserInfo.txt file, and updates the tunnel
#         if the IP Address has changed.
#
#       TunnelBrokerUpdater: Takes User Information and IP Address, and updates Tunnelbroker IPv6 Tunnel if necessary.

Also, if you need to hash your password, I have a script for that:

#       I combined two scripts from http://wiki.python.org/moin/Md5Passwords and
#       http://www.geekademy.com/2010/10/creating-hashed-password-for-vnc.html The geekacademy code is not offered under any license,
#       so I may have to change the licensing terms if pressed to. However, I believe that the combination of code here is different
#       enough from both snippets, that there shouldn't be any issues.

if __name__ == '__main__':
    import sys
    import hashlib
   
    #If the script was called with a password, then it will hash that. Otherwise, the user will be prompted for their password.
   
    if len(sys.argv) > 1:
        print hashlib.md5(sys.argv[1]).hexdigest()
    else:
        unhashpass = raw_input( "Enter your password here. " )
        print  hashlib.md5(unhashpass).hexdigest()


Once I'm sure it works, I'll upload a tar.gz file that contains the license, a README file, my contact information, and a blank UserInfo.txt file (along with the script(s)) to my website (and can upload them here as well, if requested).

Thanks, and have a great day:)
Patrick.
