Using Telnet to Access Remote Machines and Servers

What is Telnet?

Telnet is an Internet protocol that enables users to connect and interact with remote computers and networks over the Internet. By using the Telnet protocol, a user can access the command line of the remote computer, allowing them to issue commands and access programs, files and services located on the remote system.

How Does Telnet Work?

Telnet is an application layer protocol that uses TCP/IP (Transmission Control Protocol/Internet Protocol) to form a two-way communication between a client and a server. The client establishes a connection with the server and sends a request, which is then processed by the server and sent back as a response. Once the connection is established, the user can log in and access the command line interface of the remote computer.

Benefits of Using Telnet

Telnet is a widely used technology for remote computer access. It's secure, reliable and efficient, making it ideal for managing remote systems. Additionally, it allows users to perform maintenance and troubleshooting tasks on distant systems quickly and easily. With Telnet, IT admins can manage multiple systems from a single location and make changes to settings without having to physically visit the machine.
