What do I need to build a captive portal?

Question

I've been asked to build a captive portal, but have not done it before. However from the wikipedia page titled Captive Portal I determined that I have the basic skills needed ie:

-web design
-basic php
-basic Linux server admin using LAMP
-managing LAMP virtual hosts

What else do I need to know? Assuming
my client wants the server on Linux.

Answer 1

assuming that you want to use the captive portal for a wifi solution, you can simply do it in php and then have your AP's redirect the http traffic to the LAMP server for authentication.
