INTRODUCTION
============

Use this Nmap script to quickly determine the types of authentication supported
by each targeted VNC server. Particularly useful when probing large environments
for servers that do not require authentication.

Features include:

- Exceptional speed, thanks to the Nmap Scripting Engine.
- Support for all official authentication types 
- Support for both 3.3 and 3.8+ protocol versions
- Runs wherever Nmap can run (Windows, Mac, Linux, BSD, etc)

INSTALLATION
============

Simply copy the file to your local Nmap scripts directory, or the local
directory from which Nmap is being executed. An example, though this path
will vary between operating systems and distributions:

/usr/local/share/nmap/scripts/

USAGE
=====

Call the script using the --script Nmap argument.

Example: 

nmap -P0 --script=vnc-auth.nse -p 5900 192.168.2.166

Each discovered VNC server will be listed with its supported security type(s):

Starting Nmap 5.00 ( http://nmap.org ) at 2009-10-28 13:32 EDT
Interesting ports on 192.168.2.166:
