RADIUS Clients

A RADIUS client is a network device or a software application that contacts ClearBox Server when it needs to authenticate a user or to record network connection accounting information. RADIUS clients are often referred as NAS, Network Access Servers. A client sends authentication or accounting request to ClearBox server. Then the server checks the authenticity of a user and replies with either accept or reject messages.

You may specify the list of authorized clients in several ways:

• Plain list of clients known to the server. You should then manually create then a node for each client, define its IP address and a secret shared with the server.
• List of clients stored in a database table. When defined, the server loads this list at startup. All you need it to select a database source where the list of clients is stored, and a SQL query retrieving them.
  This option may be useful when the number of clients is too high, or it's easier to manage them in a database table.
• Client secrets and addresses queried dynamically by the server at run-time when it receives a request from unknown client. It may be used when clients are added to a database dynamically and are not known at the server startup.

A client may have a default realm. If no realm is chosen by realm selection rules, then this client's default realm is used for packet processing.
