![]() Replace with the IP address of the device you want to scan. To identify the services and open ports running on a specific device, you can use the following command: This will scan the network and return a list of all the devices connected to it, along with their IP addresses. Replace with the address of the network you want to scan. Once Nmap is installed, you can use it to scan the network by entering the following command: nmap -sn To install Nmap on the Raspberry Pi, open a terminal window and enter the following command: sudo apt-get install nmap Step 3: Scan the Network Nmap allows you to scan a network and identify the devices and services running on it, as well as the open ports on those devices. The first step in creating a network scanner is to install the Nmap tool, which is a free and open-source network mapping utility. ![]() You can install these tools using the command line or by downloading a package from the internet. There are several options to choose from, including nmap, Zenmap, and Angry IP Scanner. Next, you will need to install a network scanning tool on your Raspberry Pi. Make sure to connect your Raspberry Pi to a network using an Ethernet cable or WiFi. You can follow the official Raspberry Pi documentation to install the operating system (OS) and configure the device. To create a network scanner using a Raspberry Pi, you will need to follow these steps: Step 1: Set up your Raspberry Pi:įirst, you will need to set up your Raspberry Pi. You will also need to have a basic understanding of how to use the command line and install software on the Raspberry Pi. How to create a network scanner using a Raspberry Piīefore you begin, you will need to have a Raspberry Pi set up and running, with a compatible operating system installed. There are many different types of network scanners available, including command-line tools, graphical user interface (GUI) tools, and web-based tools. It can be used to identify vulnerabilities, troubleshoot issues, and monitor network activity. What is a network scanner?Ī network scanner is a tool that allows you to scan a network for devices, services, and open ports. One of the key benefits of the Raspberry Pi is its ability to run a full Linux operating system, which makes it easy to install and use network scanning tools. It is often used for educational and hobbyist projects, and is popular among makers and DIY enthusiasts. What is a Raspberry Pi?Ī Raspberry Pi is a small, low-cost computer that is about the size of a credit card. In this article, we will show you how to create a network scanner using a Raspberry Pi, a low-cost and powerful mini-computer. It allows you to quickly identify services, open ports, and other network details on a given network. From here you can discover the IP address for each Pi.A network scanner is a valuable tool for any network administrator or security professional. You'll notice here that I have a few devices, but after a quick scan you'll notice a few Raspberry Pi's connected to the network. ![]() ![]() MAC Address: B8:27:EB:95:6D:7A (Raspberry Pi Foundation) MAC Address: B8:27:EB:79:49:F2 (Raspberry Pi Foundation) You'll then see a list of devices connected to the network: Nmap scan report for (192.168.1.78) If you're running on a unix system, you might be required to run this command using sudo: sudo nmap -sn 192.168.1.0/24 Once we determine the subnet range, we'll use it with the nmap command: nmap -sn 192.168.1.0/24 So other devices on the same network are going to have addresses that share the first three octets: 192.168.1. You're IP address will likely be something like: 192.168.1.181. LinuxĪnd on linux, type hostname -I in a shell. ![]() On Windows, open the Network and Sharing Center (Control Panel > Network and Sharing Center > View network connections). On a Mac, open the Network Utility (cmd + space, then search for Network Utility). To do this we'll have to find the IP address of our local computer. We can use nmap to scan our local network to find all devices that are connected. ![]()
