Dynamic Keys

Introduction

One of the most powerful features of the Login Pages is the Dynamic Keys feature.
Unfortunately it is also one of the most misunderstood.
This dedicated Wiki Page aims to make the aspects around the Dynamic Keys more clear.

When connecting to a Coova Chill based Captive Portal you will be redirected to the UAM URL.
Coova Chilli does this automatically and also formulate the query string that is automatically appended to the UAM URL.
The components and values of the query string is mostly determined by the configuration dessings of Coova Chilli.
Here is a sample of the login page with its query string.
https://cloud.radiusdesk.com/login/bootstrap5/index.html?res=notyet&uamip=10.1.0.1&uamport=3990&challenge=fa6f27d215141b0b86f67b423352349a&called=0A-B4-B1-A2-87-AA&mac=68-17-30-D2-AC-AA&ip=10.1.1.0&ssid=our_internet_cafe&nasid=our_internet_cafe_mcp_34&sessionid=164365906100000001&userurl=http%3a%2f%2fdetectportal.firefox.com%2fcanonical.html&md=15CB9AD5DCFB726093B7B99CC4EAF6CC&i18n=fr_FR#
With the Coova Chilli configuration we for instance have
- nasid = our_internet_cafe_mcp34
- ssid = out_internet_cafe
Some settings must be unique to the Coova Chilli instance e.g. nasid.
Other settings can be more generic and can be common between a couple of Coova Chilli instances e.g. ssid.
If our Login Page have not yet been configured with any Dynamic Keys you will get the following screen.
