Hi Folks
I’m running a hotspot/captive portal with RADIUS authentication .. I noticed that some sessions do never get terminated even if they exceed the max daily session limit I specified in the RADIUS. The NAS device sometimes sends 1 or 2 accounting updates then it stops sending more updates .. this keeps the session open and disables the user from opening a new session if he’s limited to only 1 session at a time ..
Here is a screen shot of the RADIUS accounting data (max daily session is 2700seconds and update period = 300seconds):
Notice that the first and the last sessions were properly terminated with a value not equal to NULL. Though, the middle 4 sessions are still open although time now (indicated by acctstoptime of the last session) is way beyond 45mins (2700secs) from the beginning of these 4 sessions!
Any reason for this? .. and how to stop that from happening?
