Dialup Admin NAS List

I'm hoping someone may be able to assist in modifying the user_finger.php script to retrieve the list of NAS's for the online users from radacct table. Basically instead of reading the text file and cycling through them to add the breakdown of NAS's I want to use something like select DISTINCT NASIPAddress from radacct add them to an array and use the php gethostbyaddr() function to retrieve the true hostname to sort them by I don't need any of the snmp or NAS type or number of lines left as my upstream does not allow me to connect to verify the information anyway . This should just be a quick change for someone more talented than I to remove the existing loop and replace it with the relevant sql loop instead. Anyone ?
