To turn on the telnet server on a Debian Linux system, you can install the telnetd package and enable the telnet service.
To install the telnetd package, you can use the apt-get command:
sudo apt-get update sudo apt-get install telnetd
This will install the telnet server and its dependencies.
Once the telnet server is installed, you can use the systemctl command to enable the telnet service.
To enable the telnet service, you can use the following command:
sudo systemctl enable telnet.socket
This will enable the telnet service to start automatically when the system boots.
To start the telnet service immediately, you can use the following command:
sudo systemctl start telnet.socket
You can find more information about the apt-get and systemctl commands and their options in the Debian documentation or by running the apt-get --help and systemctl --help commands.
Keep in mind that the telnet protocol is insecure and should not be used for sensitive information. It is recommended to use secure protocols such as SSH instead of telnet.
You can find more information about using the telnet server on Debian Linux systems in the telnet documentation or by searching online.
