Port 1646 RADIUS Accounting

Remote Authentication Dial In User Service (RADIUS)

RADIUS accounting consists of an accounting server and accounting clients (Lucent (formerly Livingston Enterprises)PortMaster products). RADIUS accounting starts automatically when the RADIUS server starts. On a UNIX host, the radiusd accounting daemon is a child process of the radiusd authentication daemon. The RADIUS accounting server uses the User Datagram Protocol (UDP), and listens for UDP packets at port 1646 by default.
