RADIUS

About RADIUS

Remote Authentication Dial-in User Service (RADIUS) was originally used to authenticate people logging in to the network through a modem to remote points of presence (POPs). If your environment includes a RADIUS server, you can configure NetCache to authenticate users and allow access to services using the RADIUS server.

For RADIUS, the NetCache client hop uses clear-text authentication. For the server hop, NetCache authenticates through an MD5 hash comparison of a shared secret between the RADIUS server and NetCache.

Preparing to configure

Before you begin to configure RADIUS authentication in NetCache, verify the following:

The RADIUS server IP address is correct.
Your RADIUS server and the appliance are positioned on your network so that NetCache can open a UDP connection.
For the server port to which NetCache connects to the server: the RADIUS default port number is 1812.
NetCache and RADIUS are configured with a shared secret.
