OSX Lion tether to Android script using Azilink and Tunnelblick
#!/bin/bash
#
# azilink for OS X Lion
# based on http://pastie.org/405289 but works with Tunnelblick only
# (no need to install a separate copy of OpenVPN2 from macports
# or building from source by hand, thankfully)
# Requires:
# - azilink running on android phone (http://code.google.com/p/azilink/)
# (run the app and check the box to start the service).
# - adb on system path (comes with the Android SDK;
# add its tools folder to your PATH in ~/.profile or
# place or symlink the sdk's tools/adb file in e.g. usr/local/bin or somewhere else on the PATH)
# - Tunnelblick, a nice OS X packaging of OpenVPN (http://code.google.com/p/tunnelblick/)
# Install Tunnelblick to Applications. Tested with Tunnelblick 3.2beta32 (build 2817)
