Hello to all. This is a theorically question Im working to validate GPRS users with freeradius( WIFI users goes ok). I want to know the state of this machines, when they are logged. For that Im using nagios, to check the state. I must join both solutions. The AAA solution and the check Solution. I should write a custom script for the authorization section, retrieve the parameters of the Access-Request. User-Name, ip is passed as an arguments, or passed as additional arguments or another posibilitie is to make a sql query to insert all the values needed to a nagios database, so nagios can check it periodically I haven't clear wich is the way. Another question is how can I run scripts after the user is validated Thank you for your opinion Alfonso Guerendiain oliver
