Как установить telnet на windows server 2019

This post will show you how to install the telnet client in Microsoft’s Windows Server 2019. I’ll show examples with command prompt, PowerShell, and of course using the graphical user interface.

By default the telnet client in Microsoft’s Windows operating systems is disabled, this is unfortunate as it is an extremely useful tool which can be used for testing TCP connectivity to external hosts on a specified port.

This is great when you’re trying to troubleshoot network connectivity problems, for example, say we have a web server which should be listening on port 80 to serve HTTP traffic but we are not able to load a web page, by using telnet to connect to the web server on port 80 we can verify the connectivity.

Enabling the Telnet Client

Firstly you need to enable the telnet client, if you don’t enable it you’ll get a result similar to the below message when trying to use it.

C:>telnet google.com 80
'telnet' is not recognized as an internal or external command, operable program or batch file.
C:>

You can enable the telnet client either by command line or through the graphical interface.

Enabling the telnet client through command prompt

Using the command line is the easiest and fastest way to install the telnet client. Run the below command in command prompt with administrator permissions.

dism /online /Enable-Feature /FeatureName:TelnetClient

That’s it, after a few seconds telnet should be ready to use.

Enabling the telnet client through PowerShell

Again we can also do this instead with PowerShell, we can run the below cmdlet in a PowerShell console with administrator permissions which will install the telnet client.

Install-WindowsFeature -name Telnet-Client

Once complete, you should see the following output returned:

Success Restart Needed Exit Code      Feature Result
------- -------------- ---------      --------------
True    No             Success        {Telnet Client}

Enabling the telnet client through the graphical user interface

1. Open Server Manager.
2. From Server Manager click “Add roles and features”.
   
3. The Add Roles and Features Wizard opens to the Before you Begin screen, click next.
   
4. On the Installation Type screen, leave Role-based or Feature-based installation selected and click next.
   
5. On the server selection screen, select the server to install on. By default it should be the local server itself, click next.
   
6. On the Server Roles screen, click next. We are installing a feature rather than a role so don’t select anything here.
   
7. On the Features screen, tick the check box next to Telnet Client.
   
8. On the Confirmation screen, click Install.
   
9. Once the installation succeeds, click the Close button. The telnet client is now installed and ready for use.
   

Verifying that the telnet client is enabled

Simply open command prompt or powershell, type ‘telnet’ and press enter. If this was successful you should have a prompt similar to the below:

Welcome to Microsoft Telnet Client

Escape Character is 'CTRL+]'

Microsoft Telnet>

This confirms that you have successfully turned on and enabled the telnet client in Windows Server 2019.

Summary

Now that you have installed telnet in Windows Server 2019 you should be able to start issuing commands with it and using it to troubleshoot TCP connectivity problems.

Hello, Today we are going to talk about Telnet. This is a network protocol that allows us to access another machine to operate it remotely as if we were sitting in front of it. It´s also the name of the computer program that the client implements. Its name comes from the acronym Telecommunication Network. In addition, it is used on MSDOS and Windows systems. And also compatible with UNIX-based systems, such as Mac and Linux, and FreeBSD. On the other hand, this protocol and this command are only implemented through commands. However, Telnet has a serious security problem. Indeed, information from one terminal to another travels without any type of encryption, only in plain text. For this reason, safer tools such as SSH are currently preferred. Although it is still useful in internal networks with protection from external traffic. That’s why we’ll see how to enable Telnet in Windows Server.

Enabling Telnet on Windows Server 2016/2019. Using PowerShell

To be able to use Telnet correctly we have to open a session in the destination machine. This session has to be opened with a user with access. As mentioned above, this protocol presents an important security gap. For this reason, it is disabled by default in Windows Server. It is possible to check this by running the telnet command at a command prompt:

To enable it, please open a PowerShell with administrative privileges and add the following command and press Enter:

 Install-WindowsFeature -name Telnet-Client 

Immediately start the installation:

At the end of the process we will see the following window:

Another way to enable this function is to open a CMD with administrative privileges and run the following command:

dism /online /Enable-Feature /FeatureName:TelnetClient 

Enabling Telnet graphical mode.

It is also possible to enable Telnet from the Windows Server 2016/2019 Dashboard. With this in mind, you have to enter the section Add roles and features.

Then press Next to continue.

In the next window, click on Role-based or feature-based installation:

Next, select the server you are going to add to Telnet.

Now, just press Next and skip the roles on this screen. Press Next to continue the installation.

Then scroll down and select the Telnet checkbox. You will see a brief description of the feature.

On the next screen, press Install to start the process.

Just wait a few seconds until Telnet is finally installed.

Testing Telnet.

After the process is finished, you just need to open any CMD and run the next command:

telnet

If everything is correct, you will see the next window:

To view the available subcommands, run the following command:

telnet /h

In the final analysis, we have seen how to install Telnet in Windows 2016/2019. Despite its security limitations, it is still a good option for communicating computers on private networks. That’s all for now, before saying goodbye I invite you to see our post about OrientDB in Windows 10. See you later!

There are certain protocols that have been developed to facilitate the lives of administrators, users and anyone who has an impact on the IT world. The Telnet protocol (Teletype Network,) is one of the most used since since its implementation in 1964 it aims to be a protocol that acts as a command line interface towards direct communication with a remote device or server, since either for remote administration tasks or to provide some type of support or configuration of the device or the entire infrastructure of the device.

A connection through Telnet makes use of the Transmission Control Protocol (TCP) as it acts as a connection to transmit data with interconnected Telnet control between the devices. Perhaps one of its shortcomings is security is that we talk about a protocol created in 1694 where security was not as critical as it is today, but there are some defense mechanisms when using Telnet.

To understand a little what Telnet does, we must know that Telnet offers to each of the users a text-oriented interactive bidirectional system communication system that connects through a virtual terminal of more than 8 bytes, the syntax used For Telnet telnet hostname port, this allows the user to execute commands directly on the server through the available Telnet commands.

Windows Server 2019 is Microsoft’s latest commitment to cover a wide range of corporate clients with a secure, reliable and scalable system, so Telnet is disabled by default in Windows Server 2019, or 2016, to avoid privacy failures and security, but for administration and connectivity reasons it may be necessary to use Telnet on Windows Server so now we will see how to activate it on Windows Server 2019 or 2016.

We also leave you the video tutorial to enable the Telnet command of Windows Server 2019 and 2016.

It may be that the connectivity is fine but there is a problem with the web server, or that the web server is stopped and the port is not listening at all, for instance. With telnet we can get a better understanding of what’s going on.

Enabling the Telnet Client

Firstly you need to enable the telnet client, if you don’t enable it you’ll get a result similar to the below message when trying to use it.
