Welcome to Tech QuickCast. Today we’re diving into SSH, “the tool for the job” when you need secure remote access to a command-line interface. SSH, or Secure Shell Protocol, has been trusted for decades to connect Linux, BSD, or Unix machines over insecure networks.

First up, Windows users. You can open Command Prompt or PowerShell and type ssh username@IPADDRESS to log in. Enter your password, and just like that, you’re in control of the remote machine. If you prefer a GUI, download PuTTY, enter your Host Name or IP, click Open, and confirm the connection.

On Linux and macOS, SSH is built right into your terminal. Launch it, type ssh user@hostname and hit Enter. If it’s your first time, type “yes” to accept the key, then enter your password. To end the session, simply type exit or press Ctrl+D.

And here’s a pro tip: to run a single command and log out immediately, use the -t flag, like ssh pi@raspberrypi.local -t "sudo poweroff". That will execute the command and close your session automatically.

That’s your one-minute guide to SSH from Windows, Linux, or macOS. Happy connecting!
