Don’t use Telnet to check a port. It’s overkill that puts you in the situation where you have to force it to abort because the server doesn’t speak telnet. Netcat (based on the old Hobbit code) or nmap’s ncat are pretty universally installed. It just opens a socket and lets you type away until EOF (^D). Or you can just do “nc -v host port < /dev/null” (or just do ”-z” for non-ncat). Hilariously my phone doesn’t have backticks for me to denote those as commands.
