Telnet is a network protocol that offers a command-line interface for Windows. Telnet is often used to communicate with other devices.

It’s worth noting that Telnet and other TCP/IP protocols are completely different. Telnet lets you log in to a server and uses it like you are an actual user. As part of this, you will get the same rights as the user who has logged in to the server locally.

Why has Telnet usage decreased?

We need to realize that Telnet was conceived in a day and age when the internet was still at its infancy. The protocol, as such, offers zero encryption and thus is vulnerable to attacks. In the early days, this was not a big issue since, like the internet, the cyberattacks were not rampant. However, things have changed, and people have switched from Telnet to web interfaces for controlling devices remotely.

Apart from playing chess, watching Starwars, you can use the following Telnet Commands.

c    - close                    close current connection
d    - display                  display operating parameters
o    - open hostname [port]     connect to hostname (default port 23).
q    - quit                     exit telnet
set  - set                      set options (type 'set ?' for a list)
sen  - send                     send strings to server
st   - status                   print status information

?/h  - help                     print help information

Many of the commands have options. You can add /h at the end reveal more. You can use Telnet for simple things like checking the status of the HTTP server, and it allows unrestricted access to a controlled system’s resources if permission has been given. However, since it is not encrypted, it is not used keeping the security concerns in mind, and if someone has access to it on your computer, a lot of things can go wrong.
