Determine the Number of Sockets Opened to a Policy Server

The Policy Server combines the following functions into one service:

• Authentication
• Authorization
• Accounting

By default this Policy Server service listens for Web Agent requests on port 44443.

Note: The Policy Server Management Console lists the default ports of 44442, 44443, and 44441 for Authentication, Authorization, and Accounting, respectively, for 5.x Web Agent mixed-mode compatibility with the Policy Server. A 5.x Web Agent can open sockets across all three ports to communicate with a Policy Server service.

The number of sockets a Web Agent opens to the Policy Server port is dependent on the following:

• The socket configuration settings in the Web Agent's host configuration object
• The web server's mode of operation and configuration
  • single-process/multi-threaded
  • multi-process/single-threaded
  • multi-process/multi-threaded

    Note: Refer to your vendor-specific documentation to determine the mode of operation in which your web server is operating.

• The Web Agent version
