How to Enable SSH on Raspberry Pi?

Enabling SSH on your Raspberry Pi is a straightforward process, but it’s crucial to follow the steps carefully to ensure a successful setup. By default, SSH is disabled on most Raspberry Pi distributions to enhance security. However, enabling it is simple and can be done in just a few steps. Here’s how you can get started:

Create an Empty File Named "ssh": If you’re using a fresh installation of Raspberry Pi OS, you can enable SSH by creating an empty file named “ssh” (without any extension) in the boot partition of your SD card. This file acts as a flag to the system, instructing it to enable SSH during the first boot.
Use the Raspberry Pi Configuration Tool: If your Raspberry Pi is already running, you can enable SSH through the Raspberry Pi Configuration tool. Simply navigate to “Preferences” > “Raspberry Pi Configuration,” then go to the “Interfaces” tab and enable SSH.
Enable SSH via Command Line: For advanced users, SSH can also be enabled directly from the terminal by running the command sudo raspi-config. From the menu, select “Interfacing Options,” then choose “SSH” and enable it.

Once SSH is enabled, you’ll need to ensure that your Raspberry Pi is connected to the same network as your local machine. You can find the Pi’s IP address by running the command hostname -I in the terminal. With the IP address in hand, you’re ready to connect using your preferred SSH client.

Which Tools Can You Use as an SSH Client?

When it comes to connecting to your Raspberry Pi via SSH, there are several tools you can use as an SSH client. The choice of tool often depends on your operating system and personal preferences. Here are some of the most popular options:
