In this task, we just have to somehow provide the password to the localhost with specific port. As the task suggests, we can use telnet to do this.
Telnet is a precursor to ssh, it does not use any encryption and (according to my limited knowledge) is mostly redundant at this point.
telnet localhost 30000
output: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.
Then if we enter the password...

Connection closed by foreign host.
