What is SSH and Why Use It for Raspberry Pi?
SSH, or Secure Shell, is a way to connect to another computer over a network, and it's pretty secure. It lets you run commands on that distant computer as if you were sitting right in front of it, which is rather handy. For your Raspberry Pi, this means you can control it without needing a screen or keyboard attached to it all the time. This kind of access is often called "headless" operation, and it's quite popular for projects where the Pi just sits quietly somewhere, doing its job.
The biggest benefit, you know, is the sheer convenience. Imagine your Pi is tucked away in a cupboard, or perhaps it's part of a smart home setup. With SSH, you don't have to pull it out every time you want to make a change or check on something. You just connect from your main computer, and you're good to go. It saves time and effort, honestly.

Beyond convenience, SSH also adds a layer of security. The connection between your computer and the Raspberry Pi is encrypted, which helps keep your commands and any information you send private. So, it's not just about ease of use; it's also about keeping your little computer safe from prying eyes, which is pretty important these days.
Getting Your Raspberry Pi Ready
Before you can actually access Raspberry Pi remotely using SSH, you need to make sure your Pi is set up correctly. This means installing the right operating system and making sure SSH is turned on. It's actually a straightforward process, and we'll go through it step by step, so you're not left guessing.
Initial Setup
First things first, you'll need to get Raspberry Pi OS onto a microSD card. We usually suggest Raspberry Pi OS Lite for headless setups, as it doesn't have a desktop environment, making it lighter and faster. You can use the Raspberry Pi Imager tool for this, which is available for Windows, macOS, and Linux. It makes the whole process quite simple, really.
When you use the Raspberry Pi Imager, there's a neat trick you can use to enable SSH right away. Before you write the image to your card, click on the gear icon (or Ctrl+Shift+X) to open the advanced options. Here, you'll find a setting to enable SSH. Make sure to check that box. You can also set a username and password here, which is a very good idea for security, as a matter of fact.
If you've already put the OS on your card without enabling SSH, no worries! You can still do it manually. After the imaging process finishes, take the microSD card out and then put it back into your computer. You should see a drive named 'boot'. Inside this 'boot' partition, create an empty file named `ssh` (no file extension). This simple little file tells the Raspberry Pi to turn on the SSH service when it starts up. It's a pretty clever way to do it, you know.
Connecting to Network
Your Raspberry Pi needs to be on the same network as the computer you're using to connect. If your Pi is near your router, a wired Ethernet connection is the easiest way to go. Just plug in a network cable, and it should connect automatically. This is often the most reliable method, actually.
For a wireless connection, things are a bit different, especially if you're running headless. You'll need to tell your Pi how to connect to your Wi-Fi network before its first boot. You do this by creating another file in the 'boot' partition of your microSD card. This file should be named `wpa_supplicant.conf`.
Open this file with a plain text editor (like Notepad on Windows, TextEdit on macOS, or Gedit on Linux) and add the following information. Be sure to replace `YOUR_COUNTRY_CODE`, `YOUR_NETWORK_NAME`, and `YOUR_NETWORK_PASSWORD` with your actual details. It's very important to get these right, otherwise, your Pi won't connect, so:
country=YOUR_COUNTRY_CODE ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="YOUR_NETWORK_NAME" psk="YOUR_NETWORK_PASSWORD" } For `YOUR_COUNTRY_CODE`, use the two-letter ISO code for your country (e.g., `US` for United States, `GB` for Great Britain). Save the file, safely remove the microSD card from your computer, put it into your Raspberry Pi, and then power it on. Your Pi should now try to connect to your Wi-Fi network, which is pretty neat, if you ask me.
Finding Your Raspberry Pi's IP Address
To access Raspberry Pi remotely, you need to know its IP address on your network. This is how your computer will find it. There are a few ways to discover this, and some are easier than others, depending on your setup. You'll definitely want to get this step right, you know.
Using a Network Scanner
One of the simplest ways is to use a network scanner app. Tools like Fing (for mobile devices) or Advanced IP Scanner (for Windows) can scan your entire local network and list all connected devices, along with their IP addresses. Look for a device named "raspberrypi" or something similar. This is often the quickest method, actually, especially if you have many devices on your network.
Checking Router's Connected Devices
Most home routers have a web interface where you can see a list of all devices currently connected to your network. You usually access this by typing your router's IP address into a web browser (often something like `192.168.1.1` or `192.168.0.1`). Log in with your router's admin credentials (these are often on a sticker on the router itself). Look for a section like "Connected Devices," "DHCP Clients," or "Network Map." You should be able to spot your Raspberry Pi's hostname and its assigned IP address there. This is a very reliable way to find it, basically.
Command Line (if connected to monitor temporarily)
If you happen to have a monitor and keyboard handy, you can temporarily connect them to your Raspberry Pi. Once it boots up, open a terminal window. Then, you can type one of these commands to see its IP address. It's a quick check, in a way:
- `hostname -I` (that's a capital 'i')
- `ip a`
Look for the IP address next to `inet` under your active network interface (like `eth0` for wired or `wlan0` for wireless). This is the exact address you'll use for SSH, so be sure to write it down, honestly.
Accessing Your Raspberry Pi from Windows
Connecting to your Raspberry Pi from a Windows computer is pretty straightforward. You have a couple of good options, and both are relatively simple to use. We'll go over them now, so you can pick the one that feels best for you, you know.
Using PuTTY
PuTTY is a very popular free SSH client for Windows. It's been around for ages and is quite reliable. You'll want to download it from the official PuTTY website. Once downloaded, just run the executable file; there's no complex installation process, which is rather nice.
When PuTTY opens, you'll see a window where you can enter connection details. In the "Host Name (or IP address)" field, type the IP address of your Raspberry Pi that you found earlier. The "Port" should typically be 22, which is the standard SSH port. Make sure "Connection type" is set to SSH. Then, click "Open."
The first time you connect, PuTTY will show a security alert asking if you trust the host. This is normal. Just click "Accept" to continue. A terminal window will then pop up, asking for your username. Type `pi` (which is the default username for Raspberry Pi OS) and press Enter. Then, it will ask for the password. Type the password you set during the initial setup (the default is `raspberry` if you didn't change it). As a matter of fact, once you enter the correct password, you'll be logged in, and you'll see the command prompt of your Raspberry Pi. You can now run commands just as if you were directly connected to it, which is pretty cool.
Using Windows Terminal/WSL
Modern versions of Windows (Windows 10 and 11) come with a built-in SSH client, so you might not even need PuTTY. You can use Windows Terminal, or if you have Windows Subsystem for Linux (WSL) installed, you can use its terminal. This is often a more integrated experience for many users, actually.
Open Windows Terminal (you can search for it in the Start menu). In the terminal window, type the following command, replacing `
ssh pi@<IP_ADDRESS>
Press Enter. Just like with PuTTY, the first time you connect, it might ask you to confirm the host's authenticity. Type `yes` and press Enter. Then, it will prompt you for the password for the `pi` user. Enter your password, and you'll be logged in. This method is very direct, and many people prefer it for its simplicity, you know.
Accessing Your Raspberry Pi from macOS/Linux
If you're using a macOS or Linux computer, accessing your Raspberry Pi via SSH is even simpler, as both operating systems have a built-in SSH client. There's no need to download any extra software, which is quite convenient, honestly.
Using Terminal
Open the Terminal application on your macOS or Linux machine. You can usually find it in your Utilities folder on macOS or by searching for "Terminal" in your applications menu on Linux. Once the terminal window is open, type the following command, making sure to substitute `
ssh pi@<IP_ADDRESS>
Press Enter. The very first time you connect, your computer will ask if you want to continue connecting, and it will show you the host's fingerprint. Type `yes` and press Enter to confirm. After that, it will ask for the password for the `pi` user on your Raspberry Pi. Type your password and press Enter. Once you've successfully entered the password, you'll be connected to your Raspberry Pi's command line. You can now run commands remotely, which is very cool, you know, and quite powerful for managing your projects.
Securing Your SSH Connection
While SSH is inherently secure, there are some important steps you should take to make your Raspberry Pi even safer from unwanted access. These steps are pretty simple but make a big difference, honestly. It's like putting a stronger lock on your digital door, in a way.
Changing Default Password
The first and most important step is to change the default password for the `pi` user (which is `raspberry`). If you set a custom password during the Raspberry Pi Imager setup, you're already ahead. If not, log into your Pi via SSH and type:
passwd
Press Enter. It will ask for your current password, then for a new one, and then to confirm the new one. Choose a strong, unique password that's difficult to guess. This is a very basic but absolutely essential security measure, you know, as default passwords are a common target for malicious actors.
Using SSH Keys
For even better security and convenience, you should use SSH keys instead of passwords. SSH keys come in pairs: a private key (kept secret on your computer) and a public key (placed on your Raspberry Pi). When you try to connect, your computer uses the private key to prove its identity to the Pi, and the Pi verifies it with the public key. This is a much stronger method than passwords, generally.
To generate SSH keys on your local computer (Windows, macOS, or Linux), open your terminal or command prompt and type:
ssh-keygen
Press Enter several times to accept the default location and an empty passphrase (unless you want to add an extra layer of security with a passphrase, which is often a good idea). This will create two files: `id_rsa` (your private key) and `id_rsa.pub` (your public key) in a hidden folder called `.ssh` in your user directory. You should never share your private key with anyone, literally.
Next, you need to copy your public key to your Raspberry Pi. The easiest way is with the `ssh-copy-id` command (available on Linux/macOS and in WSL on Windows):
ssh-copy-id pi@<IP_ADDRESS>
It will ask for your `pi` user's password one last time. After that, you should be able to connect without a password, using your SSH keys. If you're on Windows without WSL, you can manually copy the contents of `id_rsa.pub` to `~/.ssh/authorized_keys` on your Pi. This process is a bit more involved, but it's very worth it for the added security and ease of future logins, honestly.
Changing Default SSH Port
The default SSH port is 22. Many automated bots scan for open port 22 to try and brute-force their way in. Changing this to a different, non-standard port (e.g., 2222, 22222, or any unused port above 1024) can reduce these automated attacks. This is a fairly simple change, actually.
Log into your Raspberry Pi via SSH. Open the SSH configuration file with a text editor:
sudo nano /etc/ssh/sshd_config
Find the line that says `#Port 22`. Remove the `#` (which uncomments it) and change `22` to your desired new port number. For example, `Port 2222`. Save the file (Ctrl+O, Enter, Ctrl+X in nano) and restart the SSH service:
sudo systemctl restart ssh
From now on, when you connect via SSH, you'll need to specify the new port. For example:
ssh -p 2222 pi@<IP_ADDRESS>
Or in PuTTY, change the port number in the settings. This little change can make a big difference in reducing unwanted attention, you know.
