The Telnet protocol is capable of remotely managing network devices or computers over LAN or WAN. It is still popular today because it was one of the first protocols used with the launch of the Internet in 1969.
What is Telnet?
Telnet is an abbreviation of “teletype network”, “terminal network” or “telecommunications network”.
This protocol is used to configure remote hosts. So, for example, you use Serial Cable to initial configure a Cisco Router, and after you enable this protocol, you can configure it remotely from a local or remote network without being near this device.
You can configure all network devices using the TCP/IP protocol with this protocol. In addition, a user name and password are required when connecting to a remote device.
When you transfer data with this protocol, it is an unsafe protocol because of your data sends as Clear Text. Instead of using Telnet over the network, SSH protocol is preferred.
How to Use it?
To use telnet, it must first be enabled on a host to be managed. After you enable it, you can easily connect to your remote host via the TCP 23 port with Command Prompt (CMD).
There are two different structures to use/configure the Telnet protocol. These; Server and Client. If you configure a server, you must install or activate the Client service to connect to it remotely.
After the definition of Telnet, now let’s examine how to use Telnet in Windows 10.
