Telnet vs SSH Explained
PowerCert Animated Videos・4 minutes read
Telnet is an insecure terminal program used to access remote servers, prompting the recommendation of using Secure Shell (SSH) for encryption and authentication. Enabling the telnet client on a Windows machine involves activating the feature in 'programs and features,' opening a command prompt as an administrator, and accessing features like viewing a Star Wars movie in ASCII or checking the weather forecast.
Insights
- Telnet is a program for remote server access but lacks encryption, making it insecure for public internet use, leading to the recommendation of Secure Shell (SSH) for encrypted data transfer and authentication.
- Enabling the telnet client on Windows involves accessing 'programs and features,' activating the telnet client, opening a command prompt as an administrator, enabling various features like viewing ASCII Star Wars, playing chess, or checking the weather forecast for specific cities.

What is Telnet?
Telnet is a terminal emulation program used to access remote servers, allowing users to send commands remotely to administer servers, run programs, create folders, delete files, transfer files, start or stop services, and manage network devices like routers and switches.
Why is Telnet considered insecure?
Telnet is considered insecure because it lacks encryption, sending all commands in clear text, making it outdated and insecure for use over the public internet. This lack of encryption exposes sensitive information to potential interception by malicious actors.
What is the recommended alternative to Telnet?
The recommended alternative to Telnet is Secure Shell (SSH), which encrypts data during transfer and provides password and public key authentication. SSH offers a more secure method of remotely accessing servers and network devices compared to Telnet.
How can I enable the telnet client on a Windows machine?
To enable the telnet client on a Windows machine, users must access 'programs and features,' turn on the telnet client feature, open a command prompt as an administrator, and then can use telnet commands to access features like viewing a Star Wars movie in ASCII, playing chess, or checking the weather forecast for a specific city.
What are some common uses of Telnet?
Common uses of Telnet include administering servers, running programs, creating folders, deleting files, transferring files, starting or stopping services, and managing network devices like routers and switches. Telnet allows users to remotely execute commands on a server or network device without physically being present at the location.
