Downloading And Burning The ISO Image

Downloading And Burning The ISO Image
Prev	Chapter 1. Getting Started	Next

The downloading and burning of the Network Security Toolkit ISO involves the following:

Downloading the gzipped ISO image from the Files section found on the project page at SourceForge. Look for nst-2.13.0.iso.gz in the list of files available for download. You should be able to start downloading the ISO for the 2.13.0 release by pointing your browser at http://prdownloads.sourceforge.net/nst/nst-2.13.0.iso.gz?download.
You may want to compare the MD5 of the nst-2.13.0.iso.gz which you downloaded against the value in the manifest. If you have a valid copy of the Network Security Toolkit ISO image, your MD5 checksum should match the value at the web site.
You will need to uncompress the ISO image.
You may want to download and run the nstisopasswd-2.13.0.bash script to set the default password in your ISO image prior to burning. I suspect that many of you will skip this step, and later realize that you really wish you hadn't (hope you are using CDRW media).
Note
This feature became available in the 1.0.5 release.
You will then need to burn the uncompressed ISO image to a CDR or CDRW disk using your favorite CD burning software.

On A Linux System

Assuming that you have the wget, md5sum and cdrecord commands installed and configured on your system and that you've download the ISO image to the file nst-2.13.0.iso.gz, you should be able to create your bootable CD using the following set of commands:

	If the MD5 value reported doesn't match `06a5634bb659ac5ce0ba3ffb6eb2575a`, it probably means that the ISO image you downloaded did not come through clean.
	The wget utility will not set the executable flag on the script file. We do this ourselves so that we may invoke it.
	The nstisopasswd-2.13.0.bash script will only modify the contents of the ISO after verifying that the ISO image is compatible with the script. You will see an error message if you downloaded the incorrect version or your ISO image is corrupt. Note This feature became available in the `1.0.5` release.
	Omit the `blank=fast` if you are using CDR media or a fresh (already blank) CDRW.

On A Windows System

You will need to use you web browser (Internet Explorer) to download the nst-2.13.0.iso.gz ISO image from the Files area of the Network Security Toolkit project at SourceForge. If you are feeling lucky, you might be able to begin the download by clicking here.

After downloading the ISO you will need to uncompress it using either the free gzip utility or popular WinZip utility.

You will then use a CD burning package like Roxio or Nero to burn the ISO image to a CDR or CDRW.
