net is short for ‘Terminal Network’. It is a protocol that a user can use to connect a computer to a local computer.

Here, the local computer refers to the device that initiates the connection, while the computer connected to the local computer is referred to as the remote computer.

Telnet works on a client/server principle, and although it is obsolete, it is still used by many people in 2022 as well. Many people have already upgraded to the Windows 11 operating system, Microsoft’s latest operating system offering.

The good thing is that Windows 11 comes with Telnet. However, it is disabled by default. In other words, you have to activate it manually.

The same principle applies in the case of Windows 10, although there are some differences regarding the steps required to activate the service.

That’s where this guide comes in. Because in this article, we will share with you all the information you need to install and activate Telnet on your Windows 11 PC.

So, without further ado, let’s take a look at our guide on how to install and enable Telnet on Windows 11.

What is Telnet?

Telnet, as already mentioned, uses a client/server protocol to access remote servers. You can use Telnet to verify connectivity to a remote server.

Additionally, you can use Telnet to run commands on a remote server. The output of this will be sent back to the Telnet client.

It uses the Transmission Control Protocol/Internet Protocol (TCP/IP) network protocol to create remote sessions. When connected to a remote system, users can connect to the remote computer by entering their user name and password.

Since Telnet does not provide a secure way to communicate with remote servers, you can use it if strong authentication and encryption on the network is not critical.

Telnet can be used for a variety of tasks. This includes performing activities on a server, including editing files, running various programs on a remote computer, or even checking mail, if desired.

In particular, even though Telnet is no longer a secure means of communication, the Telnet client is still available on Windows 11 and Windows Server 2022. However, you must activate it manually.

Now let’s see how to enable Telnet in Windows 11.

What are the security issues with using the Telnet client?

The main reason why Telnet has been replaced by the SSH protocol in most modern systems is because of security vulnerabilities in the terminal network.

We will try to explain the security issues associated with using Telnet clients in simple terms. All your data and information travels over an unencrypted network.

This gives hackers and spies easy access to access important information such as usernames and passwords. This is the reason why SSH (Secure Shell) came into existence, which is a kind of encrypted Telnet.

The SSH protocol encrypts your data before sending it over the network and also authenticates the remote computer. In return, the SSH protocol requires additional resources to function properly. Simply put, a network using the SSH protocol must have powerful machines.

Additionally, the Telnet protocol is text-based. This limits the use case scenarios for this protocol. Telnet uses port 23, which is designed for local networks. On the other hand, the SSH protocol uses port 22.
