Published in Telnet Usage 3 mins read

To use Telnet, you need to follow a few specific steps to connect to a server or computer. Here's a breakdown of the process, based on the provided reference:

Steps to Use Telnet

Here's a step-by-step guide on how to use Telnet:

  1. Identify the Server IP Address: First, you need the IP address of the server or computer you want to connect to.

  2. Open the Run Dialog: Press Windows Key + R to open the Run dialog box.

  3. Access the Command Prompt: Type cmd into the Run box and click OK. This will open the Command Prompt.

  4. Type the Telnet Command: In the Command Prompt, type the following command, replacing (server IP address) with the actual IP address of the server and 13531 with the appropriate port number if required: telnet (server IP address) 13531

    • For example: telnet 192.168.1.100 23 (Port 23 is a common Telnet port).

  5. Enable Telnet (If Necessary): If Telnet is not enabled, you may need to enable it through Windows Features. You can find out more about how to do this online.

  6. Verify the Connection: Once you enter the command, if you see a blank cursor, the connection is generally successful.

  7. Telnet Confirmation: If you see a blank cursor after entering the command, this indicates that you have successfully connected using Telnet.

Telnet Example

Let’s imagine the server IP is 192.168.1.100 and it is listening on port 23. In the command prompt, you'd type:

telnet 192.168.1.100 23

If successful, a blank screen, or an opening message from the server, will appear.

Important Points:

  • Port Numbers: Telnet often uses port 23, but you may encounter other port numbers depending on the server configuration.
  • Security Concerns: Be aware that Telnet is not a secure protocol. It transmits data in plain text, making it vulnerable to interception. Consider using SSH instead for more secure remote access when possible.
  • Operating System: The specific steps to open the command prompt or enable Telnet may vary slightly depending on your operating system.
