~ a script to identify devices on your network by their MAC addresses.

MAC Address Finder

Overview

This bash script is designed to continuously scan a local network using nmap, extract MAC addresses from the scan results, and search for corresponding names in a text file. It provides a simple and effective way to monitor network activity and detect any unauthorized devices.

Prerequisites

• nmap and bash installed on the system
• Text file (list.txt) containing MAC addresses and corresponding names

Notes

1. Devices can manually set their MAC addresses, potentially leading to inaccuracies in identification.

Usage

1. Example list.txt Format
   • Make sure that all capital letters

   00:11:22:33:44:55 = Device1
   AA:BB:CC:DD:EE:FF = Device2

2. Manually put your target IP range in the script:

   # Run the nmap command and store the output in a variable
   # change your target here
   nmap_output=$(sudo nmap -sn YOUR_TARGET_IP_RANGE)

3. Make the script executable:

   chmod +x mac_address_finder.sh

4. Execute the script:

   ./mac_address_finder.sh
