3 | [RADIUS] is an authentication, authorization and accounting protocol for terminals on a network, designed by a company called Livingston. A [RADIUS] server provides a central database for authentication that the remote end of your connection to an [ISP] can query to verify your credentials. This allows the account information to be maintained in a centralized resource and even be shared among [ISP]s if they share customers or resell one another's services. Terminals share a secret with the [RADIUS] server so that not just anyone can go checking passwords against it. | ||

18 | *1646 for Accounting. | ||
13 | LindsayDruett | 19 | To operate with FreeRADIUS, you will need to change the ports and since FreeRADIUS use the standards compliance ports, it's best to change the ports on the [Cisco] device. |
