The "nstnetcfg" script is a command line software utility used in an NST distribution to assist the System Administrator with the configuration of each physical network interface adapter and access control to the NST WUI using HTTPS. When an NST system is configured with two or more network interfaces, it may be easier to manage the network configuration for each interface device using the "network" service rather than under the control of the "NetworkManager" service.

When using a Wireless NST system (e.g., A Wireless Notebook), it is best (i.e. simplified and easier) to allow the "NetworkManager" service to control and setup the Wireless adapter configuration and let the "network" service setup 'stealth' interfaces for network surveillance usage. The nstnetcfg utility was designed to allow the management of network interface adapters on an NST system using different combinations of the "NetworkManager" and the "network" service.

The nstnetcfg script can also be used to create specialized Network Interface features including: IPv4 Address Aliasing, Device Renaming, and Network Interface Device Bonding. IPv4 Address Aliasing allows you to configure multiple IPv4 Addresses onto a physical Network Interface device. Device renaming allows the ability to Rename a Network Interface Device thus providing a predictable Network Interface Name that is stable and available after each successive system reboot. Network bonding provides a method for aggregating multiple Network Interfaces Devices into a single logical "Bonded" interface.

See the example NST system configurations in the section below to better explain the use of the "nstnetcfg" tool and a scenario that may best fit your overall NST network configuration setup strategy.
