By: Paulino Calderon

Overview of this book

Nmap is one of the most powerful tools for network discovery and security auditing used by millions of IT professionals, from system administrators to cybersecurity specialists. This third edition of the Nmap: Network Exploration and Security Auditing Cookbook introduces Nmap and its family - Ncat, Ncrack, Ndiff, Zenmap, and the Nmap Scripting Engine (NSE) - and guides you through numerous tasks that are relevant to security engineers in today’s technology ecosystems. The book discusses some of the most common and useful tasks for scanning hosts, networks, applications, mainframes, Unix and Windows environments, and ICS/SCADA systems. Advanced Nmap users can benefit from this book by exploring the hidden functionalities within Nmap and its scripts as well as advanced workflows and configurations to fine-tune their scans. Seasoned users will find new applications and third-party tools that can help them manage scans and even start developing their own NSE scripts. Practical examples featured in a cookbook format make this book perfect for quickly remembering Nmap options, scripts and arguments, and more. By the end of this Nmap book, you will be able to successfully scan numerous hosts, exploit vulnerable areas, and gather valuable information.

Discovering hosts with ARP ping scans

ARP ping scans are the most effective way of detecting hosts in LAN networks. This makes them the preferred technique when scanning local Ethernet networks, and Nmap will use it even if other ping options were specified. Another interesting advantage is that Nmap uses its algorithm to optimize this scanning technique. This 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 -sn -PR <target>

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

# nmap -sn -PR 192.168.0.1/24
Nmap scan report for 192.168.0.1 Host is up (0.0039s latency).
MAC Address: F4:B7:E2:0A:DA:18 (Hon Hai Precision Ind.) Nmap scan report for 192.168.0.2
Host is up (0.0037s latency).
