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.

Discovering hosts with ARP ping scans


Ping scans are used by penetration testers and system administrators to determine if hosts are online. ARP ping scans are the most effective wayof detecting hosts in LAN networks.

Nmap really shines by using its own algorithm to optimize this scanning technique. The following recipe goes through the process of launching an ARP ping scan and its available options.

How to do it...

Open your favorite terminal and enter the following command:

# nmap -sP -PR 192.168.1.1/24 

You should see the list of hosts that responded to the ARP requests:

# nmap -sP -PR 192.168.1.1/24 


Nmap scan report for 192.168.1.102 
Host is up. 
Nmap scan report for 192.168.1.103 
Host is up (0.0066s latency). 
MAC Address: 00:16:6F:7E:E0:B6 (Intel) 
Nmap scan report for 192.168.1.254 
Host is up (0.0039s latency). 
MAC Address: 5C:4C:A9:F2:DC:7C (Huawei Device Co.) 
Nmap done: 256 IP addresses (3 hosts up) scanned in 14.94 seconds
