What is an SSH key

An SSH key (has a public and private part) serves to connect a client to a server. Additionally, it is an automatic process. That is, you do not have to enter your password each time you access the service. In addition, it is not necessary to send the password over the Internet. The nature of the key prevents brute-force attacks. This prevents a potential attacker from guessing the credentials correctly. Please note that security is a critical issue.

How to create an SSH key in Windows 10

This is a quick and easy process to do. First, you need to check if the OpenSSH client is installed on Windows 10. By default, it should be enabled. However, let’s see how to check it. In the first place, enter the Windows settings by pressing the Win+I combination. Once there, enter the Apps.

Once there, please click on the optional applications

Then, verify that the client is installed. If not, press install and restart the computer to save the changes.

After verifying that the client is active, it is time to generate the SSH key. To do this you need to open a Command Prompt as an administrator. With this intention, please write in the CMD search bar and run it as an administrator.

Then execute the following command:

ssh-keygen

The first thing the system will do is ask for the destination folder. You can choose anyone, or leave it as default. If so, just press Enter. Next, you need to enter a password and confirm it. Also, you can not assign a password. But this doesn’t sound very smart, does it? After confirming the password, the key will be generated. In effect, the public and private key is displayed in RSA 2048 algorithm.

If you use the file browser to go to the destination folder, you will see the successfully generated keys.

Conclusion

In this simple way, we have seen how to generate an SSH key in Windows 10. This simple method allows increasing the security in the communications. Well, that’s all for now. Please take a look at our post about the problems with deleting user profiles in Windows 10. So long!

Install SSH Server on Windows Server 2019

The first thing you have to do is open a PowerShell with administrative privileges. To do this, press the Win+X combination, then add the following command:

 Get-WindowsCapability -Online -Name Open* 

As you can see, the OpenSSH Client and OpenSSH Server packages are available for installation.

Next, we’re going to install the SSH client. With this intention please type the following command in a PowerShell with administrative privileges:

 Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0 

Check the operation of the SSH server.

To check the status of the SSH server installation, run the following commands:

 Get-Service sshd 
 Get-Service ssh-agent 

As you can see, the service is stopped. So before you start them, you need to enable them to start with Windows startup. With that intention write the following in the PowerShell:

 Start-Service sshd 
 Start-Service ssh-agent 

Testing the SSH server

Once the OpenSSH server is installed and configured in Windows Server, you only need to test it. If you want to know how to use an SSH client in Windows 10, please check here. Consequently, you only have to open a console from Windows 10 or any device with an SSH client and type the following:

 ssh administrator@PMserver

Please keep in mind that after the at you must type the name of the server you want to connect to. A warning window will appear, where you have to type Yes and then press Enter. Now, enter the password corresponding to the administrator user.

After entering the password, the connection is successfully established. Now you can enter any command as if it were physically in front of the server.

Installing the SSH client on Windows Server 2019.

After configuring the OpenSSH server, we will enable the SSH client. Consequently, we will be able to connect to another SSH server from our Windows Server computer. With this intention, type the following command in a PowerShell with administrative privileges:

 Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

To test the functioning of the client, just type SSH.

Using the OpenSSH client

Next, let’s test the connection by opening a cmd and entering the ssh command, followed by the user name, the @ and the IP address of the server. Then, add the user’s password and press enter.

ssh coolr@192.168.X.XX

Finally, we access a remote computer using the SSH protocol.

Finally, we have seen how to enable a client and an SSH server in Windows Server. Under those circumstances, it is now possible to connect to any OpenSSH server. It is also possible to remotely access our server using this technology. That’s all for now, I hope you enjoyed this tutorial.

Prerequisite

In order to enjoy all the benefits of this protocol, it is necessary to have a Windows version equal to or greater than 1803.

Installing the SSH client

First, let’s verify the SSH client installation. With this intention, enter in Windows Settings pressing the combination Win+I. Once there, select Apps

Then click on Optional features.

In the next window, you will see all the optional functions. Then scroll down to find the OpenSSH Client. In this case, the client is already installed, so there is nothing else to do. In case it is not, just click on the install button.

Add SSH server in Windows 10

From the previous screen please click on Add a feature:

Now scroll down and select OpenSSH Server. Press install and wait a few seconds while the function is installed. Once the action is executed, please restart the computer to confirm the changes.

Configure OpenSSH Server to start with Windows.

From now on the client and the SSH server are installed. For the SSH server to be activated every time we start Windows we will have to do the following. Press the Win+R combination and run services.msc

Then scroll down and select OpenSSH SSH Server and OpenSSH Authentication Agent:

Now what we are going to do is to activate them so that they start every time you start Windows. With that intention double-click on OpenSSH Authentication Agent and in the startup type select Automatic. Then press Apply and finally accept.

We will repeat this procedure with the OpenSHH SSH Server Service

As we did in the previous step, restart the computer to set the changes. With these steps, we will be able to install the server and the SSH client in Windows 10.

Testing the SSH client and server

After restarting the computer, it is necessary to verify if the SSH services are active. To do this, open a PowerShell as administrator by pressing the Win+X combination.

Then execute the following command:

 Get-Service -Name *ssh* 

If all goes well, you will see the next result in the PowerShell, showing the two services running:

Configuring the Windows firewall

In order to have access to our computer through SSH we have to configure the Windows Firewall. To do this we open a PowerShell as administrator and execute the following command:

.\netsh advfirewall firewall add rule name="SSHD Port" dir=in action=allow protocol=TCP localport=22 

It then tests whether the SSH server is listening on port 22. For this purpose, from a PowerShell with administrator privileges runs the following command:

.\netstat -bano | .\more.com

Connect to an SSH server from Windows.

From now on we can connect remotely to an SSH server. To execute it, it is necessary to know 3 parameters:

• User name
• Server IP Address
• Know the port where the SSH server is listening. In this case, the port is 22.
• User password

Once this data is known, open a PowerShell and run the following command:

 ssh -p 22 coolr@192.168.1.58

Then add the password to access the remote computer. And you will have access via PowerShell to the SSH server.

Conclusion

Finally, we have seen how to install an SSH client and server in Windows 10. This way we will be able to remotely manage any device that uses this protocol. Additionally, security is increased because the communication between host and client is encrypted. In this way, our data remains safe from possible attackers. This is all for the moments, before saying goodbye I want to invite you to see our post about Telnet in Windows Server.

Prerequisites. Installing OpenSSH server.

To achieve better stability on our server, it is imperative to assign a static IP address. If you do not know how to do it, please look here. Furthermore, we are going to install the OpenSSH server, which will allow us to configure access to the SFTP server. Thereupon, it is necessary to enter the settings menu. And once there, select Apps.

Next, the menu corresponding to Apps and features will be displayed. In this window, click on manage optional features.

In the following window, please scroll down through the different options until you find OpenSSH Server. Check if the service is already installed, if it is not, click on Add a feature

A list of functions will appear, please navigate until you find OpenSSH Server and select it. Wait until the installation is completed.

Configuring the Ssh server to start at Windows startup.

All right, we have already installed both the agent and the OpenSSH server. Now, let is configure the services to be activated every time Windows starts. In order to do that, please press Windows +R, and type services.msc.

The service window will then open. Locate OpenSSH Authentication Agent and OpenSSH Server

In the column to the right of the service description, you can see the startup type. In my case, the authentication agent is disabled and the OpenSSH server is manual. What we are going to do is to automatically set the startup. With this in mind, do right-click over the service to enter properties.

In the next window, we have to select automatic in startup type and then click on apply. Finally, press Start to begin the service.

Please do the same procedure with the OpenSSH Authentication Agent.

Check server and client status.

After installing the services and setting up the autostart, we need to check their status. For that, we’ll open a PowerShell with administrator privileges and write the following:

 Get-Service -Name *ssh* 

If we have done everything right, we should see this message.

Connect to an SFTP server installed on Windows Server 2019, through OpenSSH.

We can connect to the SFTP server using a client like WinSCP, FTP Rush, in my case I will use FileZilla. Just go to the download page and select download client.

Run the file, and start the program. In the main window of the program, there are some boxes that we must fill with the credentials of the serve. In host type, the server name, in username adds the name of the user, type the password in the next box and finally type 22 on the Port box. Please note that at the time of installing the OpenSSH server, a firewall rule is automatically created. This rule opens port 22 to allow network access. For that reason, we have to set that number.

Finally, we have installed and configured the access to an SFTP server in Windows Server 2019. As can be seen, the procedure has been simplified since Microsoft included OpenSSH server in Windows 10 and later versions as Server 2019.
