14 - Safehouse

It's the middle of the night. Nothing but complete darkness and the moaing of approaching zombies surrounds you. You need to escape. Fast. There seems to be nothing to hide and nowhere to run. But then - a small dancing gleam appears while you are running through the blackness. Could it be? Yes - it looks like the light of a safehouse, now a few meters away. You need to get in, you need to survive. But it's locked. Looks like you need a special knocking sequence to enter. But how to get it? You have to be fast to get into safety. The Zombies are getting closer ... SSH: ctf.fluxfingers.net PORT: 1232 USER: ctf PASS: js8pps991xsgyy7
