Basic Networking Utilities

The BNUs are a group of programs, directories, and files that establish communications between computer systems on local and remote networks. It can be used to communicate with any UNIX system on which a version of the UNIX-to-UNIX Copy Program (UUCP) is running. BNU is one of the extended services programs that can be installed with the base operating system.

A group of commands related to UUCP, a UNIX-to-UNIX communication program developed by AT&T and modified as part of the Berkeley Software Distribution (BSD) are contained in BNU. 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.

Before users on your system can run BNU programs, BNU must be installed and configured.

BNU is controlled by a set of configuration files that determine whether remote systems can log in to the local system and what they can do after they log in. These configuration files must be set up according to the requirements and resources of your system.

To maintain BNU, you must read and remove log files periodically and check the BNU queues to ensure jobs are correctly transferring to remote systems. You must also periodically update the configuration files to reflect changes in your system or remote systems.
