A secure shell (SSH) is used for secure communication between devices. When most people refer to SSH, it is within the context of a connecting from a local computer to a remote server, commonly for administration tasks related to website hosting.

This article covers the basics of connecting to a remote server (such as a Linode) over SSH on a local Windows system.

Before You Begin

  1. Ensure you have a Linux server with an SSH server (like OpenSSH) installed. Most Linux distributions have an SSH server preinstalled. If you wish to deploy a new server, follow the Getting Started guide to create a Linode.

  2. If using Windows 10, install any pending updates to ensure you are running the latest version of Windows.

Open the Terminal

On your local Windows computer, open the terminal application you wish to use. The terminal allows you to access your operating system’s shell environment and run programs through the command line.

PowerShell - Windows 10

The default terminal for Windows 10 is PowerShell. To connect to a server using SSH within PowerShell, the OpenSSH client needs to be installed. OpenSSH is available on newer versions of Windows 10 (April 2018 update and later), though it may need to be manually enabled.

Install the OpenSSH Client

  1. Open up Windows Search by selecting the search area (or search button) on the taskbar or by pressing Windows + S on the keyboard.

  2. Start typing “Manage optional features” and select Manage optional features (System settings) from the search results.

    Manage Optional Features Search

  3. The Optional features page of the Settings application launches. Under the Installed features list, look for the OpenSSH Client feature.


  4. If the OpenSSH Client feature is not installed, click the Add a feature button at the top of the page. A dropdown menu appears. Select OpenSSH Client and press the Install button.

Open PowerShell

To use PowerShell, open Windows Search through the Windows + S hotkey, type “PowerShell” into the search area, and select the Windows PowerShell application from the results. PowerShell 7 or later, the newer cross-platform PowerShell application, can also be used if installed.

Windows Subsystem for Linux (WSL) - Windows 10

Instead of using the PowerShell environment (which is significantly different than both the macOS and Linux command-line environments), you can run Linux directly within Windows through WSL (Windows Subsystem for Linux). This may be preferred if you are more comfortable working within a Linux shell environment.

  1. Install WSL by following the instructions within Microsoft’s Windows Subsystem for Linux Installation Guide for Windows 10. If you already have WSL1 installed, it’s recommended to update to WSL2.

  2. Install your preferred Linux distribution, such as Ubuntu, directly from the Microsoft Store. A full list of available distributions can be found under Step 6 - Install your Linux distribution of choice of the previously mentioned guide.

Once everything has been configured, you can use the WSL environment by opening your installed Linux distribution through the Start Menu or Windows Search. By default, WSL uses a fairly basic terminal emulator. You can also use a more customizable terminal, such as Windows Terminal or Hyper.

PuTTY - Windows 8, 7, Vista, and XP

There is no native SSH client in Windows 8 and earlier. Instead, you’ll need to use a third party application, such as PuTTY, Cygwin, the Secure Shell extension for Google Chrome, or any other SSH-enabled terminal emulator:

Connecting to the Remote Server Over SSH

  1. Within the terminal, enter the following command, replacing [username] with the username of the remote user and [ip-address] with the IP address or domain name of the remote server.

    ssh [username]@[ip-address]

    The SSH client attempts to connect to the remote server over port 22 (the default SSH port).


    If the server’s SSH port is something other than 22, it needs to be specified in the SSH command. To do this, use the -p option as shown in the command below. Replace [port-number] with the port number that the remote SSH server is using.

    ssh [username]@[ip-address] -p [port-number]
  2. When you connect with a server for the first time, the SSH client prompts you to check and verify the host key’s fingerprint. This is normal, and results in output similar to:

    The authenticity of host ‘ (’ can't be established.
    ECDSA key fingerprint is SHA256:d029f87e3d80f8fd9b1be67c7426b4cc1ff47b4a9d0a84.
    Are you sure you want to continue connecting (yes/no)?

    You can verify the fingerprint by following the instructions under the Verifying the Host Key’s Fingerprint section.

  3. Accept the prompt by entering y or yes, which results in a one-time warning that is similar to:

    Warning: Permanently added 'example' (ECDSA) to the list of known hosts.

Once you have successfully connected, your terminal should be using the remote shell environment for the server. Your command prompt should now show the username and hostname configured for the server. You can now run any commands that you have available on that server. This includes many of the basic Linux commands, such as ls, cd, rm, and those covered in Using the Terminal guide. Getting to know these commands will help you navigate around your server.

Ending the SSH Session

After you are done, log out of the session by typing exit. The terminal then shows something similar to:

Connection to closed.

At this point, the shell prompt returns to the one for the local workstation and the terminal application can be closed if it’s no longer needed.

Sending Commands Over SSH

Instead of using SSH to open your remote server’s console, you can run commands on your server without leaving your local shell environment. This can enable you to quickly run commands both locally and remotely in the same terminal window.

Sending a Single Command

To run a single command on your remote server, use the following command. Replace [username] with the username of the remote user, [ip-address] with the IP address or domain name of the remote server, and [command] with the command you wish to run.

ssh [username]@[ip-address] [command]

As an example, running ssh [email protected] ls lists all the files in the home directory of the user called me. This can be useful to find the uptime of the server (ssh [email protected] uptime) or maybe determine its Linux distribution and version (ssh [email protected] lsb_release -a).

Sending Multiple Commands

To run multiple commands on your remote server (one after the other), use the following command. Replace [command-1], [command-2], and [command-3] with the commands you wish to run.

ssh [username]@[ip-address] "[command-1]; [command-2]; [command-3]"

The commands should be separated by a semi-colon (;) and all of the commands together should be surrounded by double quotation marks ("). For example, if you wanted to create a file named bar.txt in a directory called foo within the user me’s home directory, run: ssh [email protected] "mkdir foo; cd foo; touch bar.txt.

Using sudo

It’s recommended to disable root access over SSH and only log in to your remote server through a limited user account. However, some commands require elevated privileges, which can usually be accomplished by prepending the command with sudo. If you attempt to do this while running commands directly through the SSH command, you may receive an error such as “no tty present” or there isn’t a “stable CLI interface”. To run the sudo command in these instances, use the -t option, which forces a psuedo-terminal allocation. For example, to update your packages on a Debian-based system, run ssh [email protected] -t "sudo apt update".

Verifying the Host Key’s Fingerprint

  1. Log in to your remote server through a trusted method. For a Linode, use Lish.

  2. Run the command below to output your server’s SSH key fingerprint

    ssh-keygen -E md5 -lf /etc/ssh/

    The output looks similar to:

    256 MD5:58:72:65:6d:3a:39:44:26:25:59:0e:bc:eb:b4:aa:f7  [email protected] (ED25519)
    For the fingerprint of an RSA key instead of elliptical curve, use: ssh-keygen -lf /etc/ssh/
  3. Compare this output to what appears when opening an SSH connection on your local computer. The two fingerprints should match. If the fingerprints do not match, do not connect to the server. You won’t receive further warnings unless the fingerprint changes for some reason. Typically, this should only happen if you reinstall the remote server’s operating system. If you receive this warning again from a system you already have the host key cached on, you should not trust the connection and investigate matters further.

Troubleshooting SSH Connection Issues

If SSH isn’t connecting you to your Linode, you may need to investigate the state of your server. See the guide Troubleshooting SSH for assistance.
