hackney_libraries_autologin

Introduction

CLR James library offers free Wi-Fi. However, every hour my Mac gets booted off; I suspect they either require explicit re-login to demonstrate client liveliness or just don't support Macs.

This tool logs into their web portal when needed; your connection will die for on average 5 seconds before the tool kicks in.

Requirements

Python with pip.
(optional, recommended) install virtualenv and virtualenvwrapper.

Quickstart

Clone the repo.
(if you installed virtualenv and virtualenvwrapper):
- mkvirtualenv hackney_libraries_autologin
- workon hackney_libraries_autologin
pip install -r requirements.txt
Launch the Keychain Access application.
Add a new account called Hackney Libraries.
- Set the username field to your library card's number.
- Set the password to your PIN.
Quit the Keychain Access application.
Execute ./src/auto_login.py.
If you want to immediately attempt to login rather than wait for the script, press ENTER.

How it works

Use the airport command-line utility to confirm that we are both connected to a Wi-Fi network and that the Wi-Fi network's SSID is LBH-Libraries.
If the above is true, determine if we need to re-login by attempting to HTTP GET https://securelogin.arubanetworks.com/; it times out if we don't need to log in, and redirects to a login page if we do need to log in.
If we need to log in, HTTP POST to https://securelogin.arubanetworks.com/cgi-bin/login with appropriate x-url-form-encoded content, cookies, and referrer.
We get the credentials directly from Keychain Access by executing security.
