Dear All I need to do some change in Simultaneous use check strategy . In fact when a user is disconnecting by physical reasons and the session is not get stop ( in heavy load of user i should set NAS type to other ) and the user can not connect again because of Simultaneous Use limitation. So i put some script in crontab to check radacc table and find any session that not get update (*intermediate) then stop that session .* * * * * *in this case because of **Delay period in **checking** dead session , user can not connect until cron script detect dead session .* * * *So i need to change **Simultaneous Use check strategy and if user with same Calling Station ID - NAS ip address - NAS port - Called station ID try to connect i need to accept it .* * * * * *i just find some query in sql.conf about **Simultaneous Use.* * * *Is there any way to change Simultaneous Use configuration?* * * *Best regards.* * *
