Overview

This page demonstrates how to setup networking with an NST wireless notebook that is configured with multiple network interface adapters for performing simultaneous network computing surveillance tasks. The NST script: "nstnetcfg" command line software utility was designed to make this task easy to accomplish using a combination of both the "NetworkManager" and "network" services.

Note: One of the design goals of the "NetworkManager" service was to make setting up a wireless adapter in Linux a much simpler process.

The diagram below will be used as a reference for setting up a wireless notebook configured with multiple network interface adapters using NST. The notebook is shown with USB 3.0 Gigabit NIC attachments to the network infrastructure for security tasks and the wireless interface used for management connectivity. This configuration is typical for a Network Security Professional to perform mobile network surveillance tasks and penetration analysis tests.

Note: The USB 3.0 Specification defines the "SuperSpeed" mode with a signalling speed of 5 Gb/s and a usable data rate of up to 4 Gb/s. Based on this, a USB 3.0 Gigabit NIC Adapter should be capable of providing Full Line Rate Gigabit Data to the NST system.

Network Interface Setup Configuration Information

In this section we will identify each network interface and how it should be setup using the "Wireless Notebook" configuration illustrated in the reference diagram above. The NetworkManager service by default will use "DHCP" to derive its network parameters (i.e., IPv4 Adress, Subnet Mask, Host Name, Gateway Address, Name Servers, Time Servers, etc...) The table below depicts values that will be used by the nstnetcfg script.
