Hello list,
I'm new to Radius in general, so please excuse me for this question which I'm sure is probably quite simple. I've spent ages looking through the archives and have been unable to find an answer to my question.
I'm trying to set up a Wi-Fi hotspot that will use prepaid tickets (scratch-cards) using NoCatAuth 0.82 + RADIUS patch and FreeRadius 1.0.0-1 on Debian Linux i386. I have the hotspot part working fine, I am able to connect and can use a username and password combo in the /etc/freeradius/users file to authenticate and connect.
The problem I'm having is with timeouts. I understand that Session-Timeout can be sent to the NAS (in this case NoCat) on acceptance, and the NAS is supposed to handle chucking the user off after the appropriate number of seconds. I also understand that the counter module is supposed to keep track of some predefined limit and send the appropriate Session-Timeout, decrementing the time remaining as time is used up. I have enabled the counter module, put it in instantiate, authorize and accounting (making sure it is after "files" in the authorize section), and set a Max-Daily-Session value in the users file.
However, when I connect, the rlm_counter module just says "We only run on Accounting-Stop packets", but as the user is never going to log out (he is meant to time out) this means the counter never gets run, and he can stay logged in indefinitely. Do I need a patch to rlm_counter, or do I need to modify the NAS (NoCat)?
Could someone please help me with this? I know that I must just be missing some basic information on how Radius and NASes work, but I don't know what it is as I'm new to it all. Please excuse my ignorance!
Thank you very much.
