Nmap 6: Network Exploration and Security Auditing Cookbook

Overview of this book

Nmap is a well known security tool used by penetration testers and system administrators. The Nmap Scripting Engine (NSE) has added the possibility to perform additional tasks using the collected host information. Tasks like advanced fingerprinting and service discovery, information gathering, and detection of security vulnerabilities."Nmap 6: Network exploration and security auditing cookbook" will help you master Nmap and its scripting engine. You will learn how to use this tool to do a wide variety of practical tasks for pentesting and network monitoring. Finally, after harvesting the power of NSE, you will also learn how to write your own NSE scripts."Nmap 6: Network exploration and security auditing cookbook" is a book full of practical knowledge for every security consultant, administrator or enthusiast looking to master Nmap. The book overviews the most important port scanning and host discovery techniques supported by Nmap. You will learn how to detect mis-configurations in web, mail and database servers and also how to implement your own monitoring system. The book also covers tasks for reporting, scanning numerous hosts, vulnerability detection and exploitation, and its strongest aspect; information gathering.

Scanning IPv6 addresses


Although we haven't exhausted all if the IPv4 addresses as some people predicted, IPv6 addresses are becoming more common, and the Nmap development team has been working hard on improving its IPv6 support. All of the port scanning and host discovery techniques have been implemented already, and this makes Nmap essential when working with IPv6 networks.

This recipe describes how to scan an IPv6 address with Nmap.

How to do it...

Let's scan the IPv6 address representing the localhost (::1):

# nmap -6 ::1

The results look like a regular Nmap scan:

Nmap scan report for ip6-localhost (::1) 
Host is up (0.000018s latency). 
Not shown: 996 closed ports 
PORT     STATE SERVICE VERSION 
25/tcp   open  smtp    Exim smtpd 
80/tcp   open  http    Apache httpd 2.2.16 ((Debian)) 
631/tcp  open  ipp     CUPS 1.4 
8080/tcp open  http    Apache Tomcat/Coyote JSP engine 1.1 

How it works...

The argument -6 tells Nmap to perform IPv6 scanning. You can basically set any other flag in combination...
