How To Install OpenSSH Client On Windows 11 [Tutorial]

OpenSSH, short for Open Secure Shell, is an essential tool for system administrators and developers alike. It provides secure, encrypted communications over a network, allowing users to log into other computers securely and execute commands or transfer files. While OpenSSH has long been a staple in Linux environments, Windows users have also embraced it, especially with the introduction of Windows 10 and 11. In this tutorial, we’ll guide you step-by-step on how to install the OpenSSH client on Windows 11, enabling you to utilize its powerful features directly from your Windows system.

Step 1: Understanding OpenSSH on Windows 11

Before diving into the installation process, it’s essential to understand the capabilities and advantages of using the OpenSSH client on Windows 11.

Why Use OpenSSH?

  1. Secure Communication: OpenSSH uses robust encryption techniques, making it ideal for secure communication over untrusted networks.
  2. Remote Access: With OpenSSH, you can log into remote servers securely, facilitating management tasks and development workflows.
  3. SCP and SFTP: OpenSSH includes SCP (Secure Copy Protocol) and SFTP (Secure File Transfer Protocol), enabling secure file transfers between systems.
  4. Compatibility: Being open-source, OpenSSH is cross-platform; this is advantageous for users who connect to Linux and Unix-like systems.

Step 2: Checking for OpenSSH Client Pre-Installation

Windows 11 often ships with the OpenSSH client pre-installed. Before proceeding with a fresh installation, it’s worth checking if your version already has OpenSSH installed.

  1. Open Command Prompt:

    • Press Windows + R to open the Run dialog.
    • Type cmd and hit Enter.

  2. Check OpenSSH Version:

    • In the Command Prompt, type: 
      ssh -V
    • If OpenSSH is installed, you will see the version number. If not, you’ll see a message indicating that the command is not recognized.

Step 3: Installing OpenSSH Client via Windows Settings

If OpenSSH is not installed, you can easily install it via the Windows Settings app.

  1. Open Windows Settings:

    • Click on the Start button or press the Windows key.
    • Select Settings (the gear icon).

  2. Navigate to Apps:

    • In the Settings window, select Apps from the left sidebar.
    • Click on Optional features.

  3. Add a Feature:

    • Scroll down and click on the Add a feature button at the top.
    • In the search box, type OpenSSH Client.

  4. Install the Feature:

    • You should see OpenSSH Client in the list. Click on the checkbox next to it and then click on the Install button.
    • Wait for the installation process to complete. This may take a few minutes.

Step 4: Verifying Installation

Once the installation is complete, you should verify that OpenSSH has been correctly installed.

  1. Open Command Prompt Again:

    • Press Windows + R and type cmd to open the Command Prompt.

  2. Check Installation:

    • Type: 
      ssh -V
    • If it returns a version number, the installation was successful.

Step 5: Installing OpenSSH Using PowerShell

Alternatively, you can use PowerShell to install the OpenSSH Client, which some users may prefer.

  1. Open PowerShell:

    • Right-click the Start button and select Windows Terminal (Admin) or Windows PowerShell (Admin).
    • If prompted by User Account Control (UAC), click Yes.

  2. Install OpenSSH Client:

    • In the PowerShell window, type: 
      Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0
    • Press Enter to execute the command. The installation process should commence and may take a moment to complete.

Step 6: Allowing OpenSSH Through Windows Firewall

To ensure that the OpenSSH client can communicate over the network, it’s essential to configure the Windows Firewall settings.

  1. Open Windows Security:

    • Click on the Start button and select Settings.
    • Choose Privacy & Security from the left panel and then click on Windows Security.

  2. Firewall & Network Protection:

    • In the Windows Security window, click on Firewall & network protection.

  3. Allow an App Through Firewall:

    • Click on Allow an app through firewall.
    • Click on Change settings, and then the Allow another app... button.
    • Navigate to the installation directory (usually C:WindowsSystem32) and select ssh.exe.
    • Click Add to allow SSH through the firewall.

Step 7: Basic Usage of OpenSSH Client

After successfully installing OpenSSH, you can start using its features. The basic syntax for SSH is as follows:

ssh username@hostname

Example:
To connect to a remote server (e.g., example.com) as user admin, you would type:

ssh admin@example.com

Step 8: Managing Known Hosts

When you connect to a remote hostname for the first time, you will see a prompt asking if you want to add the host to the known hosts file. You can choose to do this to avoid being prompted each time you connect to the server.

The known hosts file is located in your user directory under C:Users\.sshknown_hosts.

Step 9: Generating SSH Keys

Using SSH keys is a more secure method than traditional passwords. To generate a new SSH key pair, follow these steps:

  1. Open Command Prompt or PowerShell.

  2. Generate SSH Key:

    • Type the following command: 
      ssh-keygen
    • Press Enter to accept the default file location (usually C:Users\.sshid_rsa).
    • If you want to set a passphrase for added security, type one; otherwise, just press Enter.

  3. Copying the Public Key:

    • You’ll typically need to copy the public key to the remote server to allow password-less access.
    • You can do this manually or use the ssh-copy-id command: 
      ssh-copy-id username@hostname

Step 10: Troubleshooting Common Issues

While installing and using OpenSSH on Windows 11 is generally straightforward, you may encounter issues. Here are common problems and their solutions:

  1. SSH Command Not Found:

    • Ensure that OpenSSH is installed by following the above steps.
    • Check that the path to OpenSSH is included in your system’s environment variables.

  2. Connection Refused Error:

    • This can occur if the SSH server isn’t running on the remote machine. Ensure that the SSH service is active.
    • Verify that the hostname and port number are correct. The default SSH port is 22.

  3. Permission Denied:

    • Ensure you are using the correct username and password or key pair.
    • If using a key pair, make sure your public key is properly set up in the authorized_keys file on the remote server.

Step 11: Conclusion

Installing the OpenSSH client on Windows 11 is a valuable addition for any user looking to enhance security and streamline remote connections. With this guide, you should have a clear roadmap to installing OpenSSH, verifying its installation, and utilizing its features effectively, from remote access to file transfers. Embrace the power of secure communications, and unlock possibilities for various development and administrative tasks on your Windows 11 machine. Whether you’re a seasoned professional or a beginner, OpenSSH opens up new dimensions in remote management—making it a worthy tool in your arsenal.
