As to the loging off - I didn't disconnect them I mearly set a login time in radgroupreply, guests get logged off after half an hour any way. Users after a n Hour I think. Stops the little B****ers leaving filesharing apps on all night.

For the observant of you who spotted I'd ballesd up the full version of this post on my website, I've fixed it.....

Tom

I have a lot of questions here:

1) How did you set which user to which group? I dont see any sql table that could connect radcheck? 

2) How did you force the user to disconnect?

its here: http://www.oceanhippie.net/content.php? … p;Res=1190

The above could be adapted to provide a trial period.

Users must register to use the system.
Users must confrim their email address
However if they just chance on the hotspot they're  allowed limited "trial period" to recieve the confrim email address message.
Usage limits are applied to prevent overuse of the sytem and to irritate fileshares (its bloody hard to block them).

My codes kind of a mess at the minute but if anyones interested I'll share it with some instructions.

In basic it goes something like this:
UAM and Radius are on same server, radius is using MySQL to store usernames etc.

Customised splash screen reads the mac=ADDRESS attribute that chilli helpfully sents it.
Then it looks for that mac address as a username in the Raduis users
If its not there it creats a radius user with name of ADDRESS. Now there is a unique "Guest" account specific to that computer.
If it is there then it looks that MAC (also a username in radius) up in the Radius Accounting table. If its been used more than reasonable to retrieve and email. It moves it to a different radius group, wich is no longer allowed to log in.

The splash screen has an extra form, identical to the normal login one, except the username field is hidden and preset to the MAC address of the PC.

Voila, free acess, with Identifiable users with no pre-registration required.

PART 2 Fair usage.

This one's script is easier, this is a PHP script I run off cron every hour. Punishes people who download too much stay online too long, or upload to much. Works by moving group membership around.

Bit difficult to read, but they set the bandwidth for the various groups and the reply messages for guests and expired guests and punished people.

you will need command line php to run this one.
