Connecting Two Raspberry Pi 4s via Ethernet Ports: Step-by-Step Guide

In this article, we will discuss the process of connecting two Raspberry Pi 4s directly via Ethernet ports, without the use of a router. This setup can be useful for creating a local network between the two devices, allowing them to communicate and share data with each other.

Prerequisites

Before we begin, make sure you have the following items:

Two Raspberry Pi 4 boards
Two Ethernet cables
A microSD card with the Raspberry Pi OS installed for each board

Setting Up the Network

To set up the network between the two Raspberry Pi 4s, follow these steps:

Connect the two Raspberry Pi 4s using an Ethernet cable. Plug one end of the cable into the Ethernet port of one Raspberry Pi, and the other end into the Ethernet port of the other Raspberry Pi.
Power on both Raspberry Pi 4s.
On each Raspberry Pi, open the terminal and enter the following command to configure the network settings:

sudo nano /etc/network/interfaces

This will open the network interfaces file in the Nano text editor. Make the following changes to the file:


auto eth0
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0

Save and close the file. Repeat this step on the other Raspberry Pi, changing the IP address to 192.168.1.2.

Testing the Connection

To test the connection between the two Raspberry Pi 4s, follow these steps:

On one Raspberry Pi, open the terminal and enter the following command to ping the other Raspberry Pi:

ping 192.168.1.2

You should see a response from the other Raspberry Pi, indicating that the connection is working.

In this article, we discussed the process of connecting two Raspberry Pi 4s via Ethernet ports, without the use of a router. By following the steps outlined in this guide, you can create a local network between the two devices and allow them to communicate and share data with each other.
