Telnet is the abbreviation of "Terminal Network". It is a protocol that users can use to connect one computer to a local computer.

Here, the local computer refers to the device that initiates the connection, and the computer connected to the local computer is called the remote computer.

Despite its obsolescence, Telnet is still used by many people, it runs on a client/server principal and is expected to continue to be used into 2022. The latest operating system offered by Microsoft is Windows 11, and many people have already started using it.

The good news is that Windows 11 comes with Telnet. However, it is disabled by default. That is, you must enable it manually.

The same principles apply to Windows 10, although there are some differences in the steps required to activate the service.

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

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

What is remote login?

As mentioned earlier, Telnet uses the client/server protocol for remote server access. You can use Telnet to check the connection to the remote server.

Additionally, you can use Telnet to run commands on a remote server. Its output is returned to the Telnet client.

It uses TCP/IP network protocol to create remote sessions. Users can log in to the remote computer by entering their username and password to connect to the remote system.

Because Telnet does not provide a secure medium for communicating with remote servers, you can use it if strong authentication and encryption on the network are not important.

Telnet can be used for a variety of tasks. This includes performing activities on the server such as editing files, running various programs remotely, and even checking mail as needed.

It’s worth noting that even though Telnet is no longer a secure communication medium, the Telnet client can still be used on Windows 11 and Windows Server 2022. However, you need to enable it manually.

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

What are the security issues when using Telnet client?

The main reason Telnet has been replaced by the SSH protocol in most modern systems is the security vulnerability of the terminal network.

We will try to use simple language to clarify the security risks that may arise from using Telnet clients. All your data and information is transmitted over unencrypted networks.

This allows hackers and spies to easily access important information such as usernames and passwords. SSH (Secure Shell) came into being because it is an encrypted Telnet.

The SSH protocol encrypts your data and verifies the identity of the remote computer before transmitting it over the network. In return, the SSH protocol requires some additional resources to run smoothly. Simply put, a network using the SSH protocol should have powerful machines.

In addition, the Telnet protocol is text-based. This limits the use case scenarios of the protocol. Telnet uses port 23, which is designed for LANs. The SSH protocol, on the other hand, uses port 22.
