Description selahattin_cilek@hotmail.com 2017-02-01 18:42:06 UTC 
The "hostapd" service recognises the RADIUS accounting settings and honours the "Session-Timeout" attribute but it terminates ONLY the first session when it expires, and the second session lasts forever until user turns off wifi or shuts down the host. The RADIUS reply item for the user "scilek" is set to "Session-Timeout := 600", which means "Renew session every 10 minutes."


Authentication packets received from the hostapd access point:
