First, we need to print out the password to the current user bandit14.  The location of the password /etc/bandit_pass/bandit14 was revealed in the previous challenge.  Next we can establish a connection with localhost:30000 using either netcat or telnet.  We paste the current password, once connected, and the password for bandit15 is returned.
