Kick out wireless client

Im using MT with radius authentication. But if i disable user in radius it does not kick him out until next asossiation.
Anyone knows how to kick him out by script from linux(snmp or smth else)???

Turn on Radius Incoming and send a Radius Disconnect message. I use php to fire off a command line command to do this.

Curious how are you sending a radius command from php?
php_radius?

Using php’s exec() command with the following:

$cmd = "echo NAS-IP-Address=$nas_ip_address,User-Name=$mac,Framed-IP-Address=$framed_ip_address,Acct-Session-Id=$acct_session_id | radclient $nas_ip_address:1700 disconnect $radius_password";
