I use vpnbook for all my vpn requirements. But they change the password repeatedly. Going to their website note down the password and put them back in VPN config is a robotic work. So i just automated it with python. This script automates the work, By browsing the website extracting the password and saving it to the required config files

VPNBook_password_updater_Ubuntu.py

'''
Tested in ubuntu 14.04 LTS
Usage: If you dont want the proxy you can comment out the lines 18,19,20
line_writer first argument is the file path which you need to put, then script will update password in that file
i would love to hear from you, hope this script helps you- Email:chaitanyaradon89@gmail.com
