services File

The services file can be used to assign default UDP ports for RADIUS communications to and from the SBR Carrier server. Steel-Belted Radius Carrier reads the services file at startup. Among the items of information in the services file are the port assignments for RADIUS authentication and accounting services.

Figure 1 illustrates part of a sample services file.

Sample Services File

The location of the services file is:

/etc/ (may be mapped using NIS or NIS+)

If no entry for radius or radacct is found in the services file, Steel-Belted Radius Carrier uses the default UDP ports (1645 and 1812 for authentication, 1646 and 1813 for accounting).

Steel-Belted Radius Carrier can be configured to use any available UDP ports for authentication and accounting:

  1. Use a text editor to open the services file.
  2. To set the port for authentication, set the value of the radius parameter. For example:
    radius 1812/udp # RADIUS authentication protocol
  3. To set the port for accounting, set the value of the radacct parameter. For example:
    radacct 1813/udp # RADIUS accounting protocol

    Note: Port number assignments made in the radius.ini file override the assignments made in this file. See [Ports] Section for more information.

You can determine the ports that Steel-Belted Radius Carrier is using at any time by examining the server log file for that time period.

Note: If another RADIUS server is running on the same host, you must modify the port numbers in radius.ini [Ports] section to avoid port number conflicts if the other RADIUS server binds to the default ports before Steel-Belted Radius Carrier starts.
