Overview of this book

This is the second edition of ‘Nmap 6: Network Exploration and Security Auditing Cookbook’. A book aimed for anyone who wants to master Nmap and its scripting engine through practical tasks for system administrators and penetration testers. Besides introducing the most powerful features of Nmap and related tools, common security auditing tasks for local and remote networks, web applications, databases, mail servers, Microsoft Windows machines and even ICS SCADA systems are explained step by step with exact commands and argument explanations. The book starts with the basic usage of Nmap and related tools like Ncat, Ncrack, Ndiff and Zenmap. The Nmap Scripting Engine is thoroughly covered through security checks used commonly in real-life scenarios applied for different types of systems. New chapters for Microsoft Windows and ICS SCADA systems were added and every recipe was revised. This edition reflects the latest updates and hottest additions to the Nmap project to date.

Performing advanced ping scans


In this chapter, you have learned all the different ping scanning techniques supported by Nmap. We have been using these techniques independently across different scenarios, but one of the strengths of Nmap is the ability to combine them. Discovery scans can yield better results by expanding the set of probes sent to the network, but it is up to us to optimally combine the scanning techniques and probe ports. The following recipe will go through the process of launching advanced ping scans. 

How to do it...

Open your terminal and enter the following command:

# nmap -sn --send-ip -PS21,22,23,25,80,445,443,3389,8080 -PA80,443,8080 -PO1,2,4,6 -PU631,161,137,123 <target>

You should see the list of hosts that responded to any of the probes:

# nmap --send-ip -sn -PS21,22,23,25,80,445,443,3389,8080 -PA80,443,8080 -PO1,2,4,6 -PU631,161,137,123 192.168.1.1/24
