Chapter 4. Basic Networking Utilities (BNU) Overview

The Basic Networking Utilities (BNU) establish communications between computer systems on local and remote networks. BNU is one of the Extended Services programs that can be installed with the Base Operating System.

BNU contains a group of commands related to the UNIX-to-UNIX Copy Program (UUCP) developed by AT&T and modified as part of the Berkeley Software Distribution (BSD).

BNU provides commands, processes, and a supporting database for connections to local and remote systems. Communication networks such as token-ring and Ethernet are used to connect systems on local networks. A local network can be connected to a remote system by hardwire or telephone modem. Commands and files can then be exchanged between the local network and the remote system.

Topics discussed in this overview are:

• Using BNU Path Names
