TCP/IP Network Services Database Support

The TCP/IP network services database contains information about TCP/IP server applications such as name, port, and protocol. This information is used by the getservbyname and getservbyport TCP/IP socket APIs, which allow you to retrieve the socket application port by passing the name and vice versa.

The TPF system supports an extended network services database. TCP/IP network services database support allows you to:

Note:
The TCP/IP network services database is not a replacement for the Internet daemon. The application definitions in the TCP/IP network services database are independent from the definitions in the Internet daemon configuration file (IDCF); therefore, you need to define an application in both places if you want the Internet daemon to manage the application and if you want to also collect statistical data for the application. See Operator Procedures for the Internet Daemon for more information about the Internet daemon and the IDCF.
