The command "telnet ${host}" is used to establish a Telnet connection with a specified host.
In this command, "${host}" is a placeholder for the host's IP address or hostname. You need to replace "${host}" with the actual IP address or hostname of the host you want to connect to.
Once the command is executed, the Telnet client will attempt to connect to the specified host using the Telnet protocol. If the connection is successful, you will see a prompt indicating that you are connected to the remote host. This allows you to interact with the remote system via the Telnet client.
Telnet is a network protocol that allows you to establish a remote connection to another device over a network. It is mainly used for troubleshooting purposes, remote administration, or for accessing legacy systems that don't support more secure protocols like SSH.
