The command "telnet httpbin.org 80" would be given to the system to run "telnet" and make a connection at the same time. But you're already running "telnet" when you give it, and that's not a valid command from inside "telnet".

Since "telnet" is already running, the command to make the connection would be "open httpbin.org 80" instead.
