User:Magick777/WISPr WiFi Autologin
This page documents work on automated logins to UK WiFi hotspots, and attempts to achieve native support in the N900 for WISPr auto-login, on any hotspot network that supports it.

Existing WISPr clients
WISPr clients seem to be very few and far between; it's used in network-specific clients such as the BT app, and there are generic clients for Android and iOS, but it hasn't taken off in a big way.
Design goals
My preference is for an event-driven, script-based autologin; whilst turning it into an application might take it to the masses, we then have needless complications of putting a GUI on it, running a daemon to take care of listening for new connections, etc. So, my aim is for a command line client that can be launched from dbus-scripts (or otherwise) on connection to a wireless network.
This client should
- make an HTTP GET request and determine whether we are connected
- determine whether our captive portal supports WISPr
- determine whether we have credentials per login domain
- attempt authentication and determine the response
- support multiple sets of credentials for multiple WISPr captive portals
and may
- record the logoff URL and provide a means to log off
- notify the user of relevant information during the logon process
- generate logs of its activity
- provide a way to try more than one set of credentials for a single portal
but should not
- interfere with connections to private or non-WISPr WiFi networks
- open any popups or applications that require user interaction
- be too difficult to install, configure, or understand
Design challenges
- Our WISPr client needs to speak XML, HTTP and HTTPS
- SSL support is not natively present in Maemo 5's perl or python
- Adding SSL support to python requires some SDK libs, see this thread
- We want to be non-interactive, so how do we handle logoff?
