Level Goal
The password for the next level can be retrieved by submitting the password of the current level to port 30000 on localhost.
For this challenge, I used telnet but in theory any protocol that lets you connect to a specific port should work.
(For example, nc will also work, which is probably what they were going for now that I consider it)
Once we connect, we are given a prompt.
If we enter the flag we received last time, we will get the new flag.
This seems like way to make sure you actually found the flag for 13 instead of just using the ssh key.
