NST 18 Getting Started

Overview

NST 18
SVN: 4509

This page provides a overview of getting started with the Network Security Toolkit using the NST 18 release (nst-18-4509.i686.iso). This page dicusses:

• Where to download the ISO image from.
• Different methods to live boot from the ISO image.
• Installing to hard disk.
• Initial setting of the passwords (which enables the sshd and httpd services).
• Accessing the NST Web User Interface (WUI).

Download ISO Image

You should be able to download the nst-18-4509.i686.iso image from the NST area at SourceForge (https://sourceforge.net/projects/nst/files/NST/).

Live Boot The ISO Image

Once you have downloaded the ISO image, there are several ways to live boot from it.

Using USB Flash Drive

Using livecd-iso-to-disk

Assuming you have booted from a live NST or Fedora system, you should be able to use the livecd-iso-to-disk utility to install to initialize a USB flash drive in the following manner:

rpm -q livecd-tools || yum install livecd-tools
livecd-iso-to-disk --noverify --format --reset-mbr /run/initramfs/livedev /dev/sdx1

You will need to change /dev/sdx1 shown above to the partition of your USB flash drive you want initialized. Omit the --format and --reset-mbr options if you are just updating the USB flash drive and don't want to clear everything on the partition.

Using dd

It is also possible to use the dd command to copy the contents of the ISO image to a USB flash drive having a capacity of 2GB (or more). The following demonstrates how to do this from the command line on a Mac. The diskutil utility was used prior to invoking the dd command determine the device entry for the USB flash drive and to unmount any active partitions.

Here are some things to be aware of when using the dd method:

• The entire USB flash drive is used. Hence, if you use a 16GB flash drive, you won't be able to store information on any of the remaining disk space.
• The systems which you want to boot from need to support booting from USB ISO images in addition to or instead of booting from USB FAT images. This may lead to better or worse compatibility.
• You will not have access to all of the fancy features available when using the Live USB tools (separate writable home partition, overlay, etc).

Using a Virtual Machine

If you have a virtual environment (VMware, VirtualBox, etc) installed on your system, you should be able to quickly boot directly from the ISO image. The minimum recommended settings for a virtual machine boot are:

• 1 GB of RAM
• 1 CPU
• 20 GB of disk space (if you want to install NST to a virtual hard disk).

Using DVD

If your machine is unable to boot from a USB Flash drive, you can try burning the NST ISO image to DVD and try booting from the DVD. Be aware that booting from DVD media tends to be much slower than booting from a USB flash drive.
