HowTo Setup A Server With Multiple Network Interface Adapters Using: "nstnetcfg"

Overview

This page demonstrates how to setup networking with an NST server that is configured with multiple network interface adapters for performing simultaneous network computing surveillance tasks. The NST script: "nstnetcfg" command line tool was designed to make this task easy to accomplish using the underlying "network" service.

The diagram below will be used as a reference for setting up a multi-network interface adapter server using NST. The rear panel of a 1U Server is shown with NIC attachment to the network infrastructure. The network security staff for fictitious company: "TxyCorp" would like to use NST for monitoring different network segments throughout their network computing environment. In particular, they would like to monitor traffic entering and leaving their corporation, web server traffic, all client electronic business transactions and remote traffic to and from their satellite offices.

When booting up "NST Live" or after a hard disk installation, the "Network Manager" service is on by default for managing all network interfaces found on an NST system. Network Manager provides a quick and easy method for setting up networking on a system especially with a wireless interface and DHCP for IPv4 Address configuration . When a system is configured with two or more wired network interfaces or requires a multi-homed network setup, the "network" service may be a better choice for setting up the network configuration.
