This page describes the basic steps required to get you started using the Network Security Toolkit (NST).

Create Boot Media

Before you can use NST, you will need to create a USB memory stick or DVD to boot from. This involves:

  • Downloading an ISO image (or build one from source).
  • Transferring the ISO image contents to an USB memory stick or DVD.
  • Live booting your computer using the USB memory stick or DVD.

Download ISO Image

You can find free 64 bit pre-built NST ISO images at the NST team's SourceForge project page using the link below:


You might be able to find pre-built NST ISO images elsewhere on the Internet. These other sources may offer the same or customized builds of the NST ISO image. For example, the NST Pro site (run by the NST team) offers both 32 bit and 64 bit pre-built ISO images.

Prepare Boot Media

Once you have a NST ISO image, you will need to transfer it to a USB memory stick (recommended) or DVD in order to boot a non-virtual system (if you plan to run NST within a virtual environment, you can use the ISO image directly). The Copying ISO Images To USB page and Fedora's: How to create and use Live USB provide extensive details on the preparation of USB media.

Copy ISO Image to USB

For Linux and Mac users, you can use the dd command line utility to simply copy the ISO image directly to USB media. See the Copying ISO Images To USB page for more details. While this method is easy and reliable, it consumes the entire contents of your USB memory stick (unused space is wasted).

Create Live USB Image

The liveusb-creator tool, which is available for both Linux and Windows systems, can be used to create a bootable USB memory stick. This method has many nice features and is highly recommended. However, we have come across a few systems that have difficulty in booting from media prepared this way that will boot from USB media prepared using the dd method.

Burn ISO Image To DVD

If you have a system that refuses to boot from USB media, you can burn the ISO image to a DVD and boot from DVD. We typically recommend against using DVD when possible as it tends to be much slower than USB. You can find software and instructions for burning ISO images to disks for Linux, Windows and Mac based systems (add links - not instructions).


There are two ways to boot and use NST. A live boot, allows you to try out NST or use it for temporary rescue and analysis situations. A live boot has several limitations, but allows you to run NST without modifying your system. If you find NST to be useful, you will want to perform a full hard disk installation. Once installed to a hard disk, the NST will work like a typical Linux system - except that you will have a plethora of tools available to you through the comfort of your web browser.

Live Boot and Use

When booting from your live media (DVD or USB stick), you should see a boot screen similar to the following:

NST 20 Live Boot

If you don't press a key, the Graphical Desktop mode will boot by default. Use the arrow keys to choose one of the other modes (we recommend Console mode for systems with limited amounts of resources).

Live Boot and Install

From the live boot screen, select the Hard Disk Install boot option. After a few moments (depending upon the speed of your hardware), you should be taken to the hard disk installation screen shown below.

NST 20 Hard Disk Install Screen

From this point, you should be able to proceed with the NST 20 Hard Disk Installation.

You do not need to boot directly to a hard disk installation. You can start a hard disk installation from a icon you find on the desktop or by using the nstliveinst script from the command line.

Hard Disk Boot

After a successful hard disk installation, you will see the following boot screen.

NST 20 Hard Disk Boot

Log In

When booting in Graphical Desktop mode, you will see the following login screen:

NST 20 Log In Screen

There is no password initially set, so you can simply click on the Log In button to log into the system.

Default Users/Passwords

The NST has two primary user accounts nst and root. You can log in using either of these accounts. Initially, these accounts do not have any passwords associated with them (just press the Enter key or leave the password field blank). Since the NST has no passwords set by default, both the sshd and httpd services are initially disabled. You will not have network access to your NST system out of the box.

Set Passwords

Before the NST system can be used on a network, you must set the passwords for the nst and root accounts. This is done by running the nstpasswd script. You can run this script at the command line, or you can select the Set NST Passwords icon on the desktop.

NST 20 Setting Passwords

Running the nstpasswd script not only initializes the passwords for the user accounts missing passwords, it also enables the sshd and httpd services so you will be able to remotely access your NST system.

You only need to set the NST passwords one time after a hard disk installation. For live boots you will need to set the NST passwords every time you boot the system (unless you use a persistence layer).

Bring Up the NST Web User Interface

The main advantage of using NST comes from using its Web User Interface (WUI). The WUI provides a wealth of information and immediate access to many tools on the system. You can use the WUI locally on the NST system itself, or access it remotely using any other system on your network that has one of the major browsers (Chrome, Firefox, IE, etc).

Note: Web access to the NST WUI has been changed starting with NST 22. For HTTPS access use port: "9943" (e.g., and for local HTTP access use port: "9980".

To bring up the NST WUI on your NST system, make sure that you have set the NST passwords and then click on the Firefox icon located near the top left of the screen.

NST 20 Web User Interface Login

You will be prompted to log in. Enter root as the user ID and the master password that you set. After successfully logging in, you should reach the main page. You will find a menu bar near the top of the page which allows you to quickly jump to many different tools.

NST 20 Web User Interface


The NST is packed with a lot of tools and information (it can be a bit overwhelming). The following lists a set of tools that require a minimal amount of effort to get you started with.
