Wykonanie, użycie: Access remote systems. telnet is the user interface that communicates with another host using the Telnet protocol. If telnet is invoked without host, it enters command mode, indicated by its prompt, telnet>, and accepts and executes commands. Type ? at the command prompt to see the available commands. If invoked with arguments, telnet performs an open command (shown in the following list) with those arguments. host indicates the host's official name, alias, or Internet address. port indicates a port number (default is the Telnet port).

The Telnet protocol is often criticized because it uses no encryption and makes it easy for snoopers to pick up user passwords. Most sites now use ssh instead
