Installing OpenSSH from the Settings UI on Windows Server 2019 or Windows 10 1809

OpenSSH client and server are installable features of Windows 10 1809.

To install OpenSSH, start Settings then go to Apps > Apps and Features > Manage Optional Features.

Scan this list to see if OpenSSH client is already installed. If not, then at the top of the page select "Add a feature", then:

• To install the OpenSSH client, locate "OpenSSH Client", then click "Install".
• To install the OpenSSH server, locate "OpenSSH Server", then click "Install".

Once the installation completes, return to Apps > Apps and Features > Manage Optional Features and you should see the OpenSSH component(s) listed.

PowerShell复制

Start-Service sshd
# OPTIONAL but recommended:
Set-Service -Name sshd -StartupType ‘Automatic‘
# Confirm the Firewall rule is configured. It should be created automatically by setup. 
Get-NetFirewallRule –Name *ssh*

Initial use of SSH

Once you have installed the OpenSSH Server on Windows, you can quickly test it using PowerShell from any Windows device with the SSH Client installed. In PowerShell type the following command:

PowerShell复制

Ssh [email protected]

The first connection to any server will result in a message similar to the following:

复制

The authenticity of host ‘servername (10.00.00.001)‘ can‘t be established.
ECDSA key fingerprint is SHA256:(<a large string>).
Are you sure you want to continue connecting (yes/no)?

The answer must be either “yes” or “no”. Answering Yes will add that server to the local system’s list of known ssh hosts.

You will be prompted for the password at this point. As a security precaution, your password will not be displayed as you type.

Once you connect you will see a command shell prompt similar to the following:

复制

domain[email protected] C:Usersusername>

The default shell used by Windows OpenSSH server is the Windows command shell.
