How to check the status of the telnet service in Linux?

There are two methods to check the status of the telnet service.

Option 1: Use the command line
Input the following commands in the terminal:

systemctl status telnet.service

This will display the current status of the Telnet service, including whether it is running and detailed information about the service.

Option 2: Use the netstat command
Enter the following command in the terminal:

netstat -tuln | grep 23

23 is the default port number for the telnet service. If the telnet service is running, it will display output similar to the following:

tcp        0      0 0.0.0.0:23        0.0.0.0:*        LISTEN

This indicates that the telnet service is listening on port 23 and is in a running state.

Please note that telnet service may not be installed by default in the latest Linux distributions due to security risks. It is recommended to use the more secure SSH instead of telnet.
