H OTS POT GATEWAYSystem Administration 115Defining the RADIUS Client Settings {RADIUS Client}The HSG supports Remote Authentication Dial-In User Service (RADIUS).RADIUS is an authentication and accounting system used by many Internet ServiceProviders.Nomadix offers an integrated RADIUS client, allowing service providers to track orbill users based on the number of connections, location of the connection, bytes sentand received, connect time, etc. The customer database can exist in a centralRADIUS server, along with associated attributes for each user. When a customerconnects into the network, the RADIUS client authenticates the customer with theRADIUS server, applies associated attributes stored in that customer's profile, andlogs their activity (including bytes transferred, connect time, etc.).The HSG's RADIUS implementation also handles vendor specific attributes (VSAs),required by WISPs that want to enable more advanced services and billing schemes,such as a per device/per month connectivity fee.For additional RADIUS information, see also:z “Defining the RADIUS Proxy Settings {RADIUS Proxy}” on page 118.z “Defining the Realm-Based Routing Settings {Realm-Based Routing}” onpage 121.z “RADIUS Attributes” on page 276.The “Usernames” function must be enabled for a RADIUS login. Seealso, “Defining the AAA Services {AAA}” on page 60.All subscribers attempting to gain access tothe network are validated by RADIUS.
