ebCTF: PWN100 “Step by step”

We found this server with two open ports. Can you find out what these ports do and login to the server? It is advisable to use a seperate VM for this challenge.

Nmap scan report (54.216.75.14)
Host is up (0.026s latency).
PORT STATE SERVICE
22/tcp open ssh
8140/tcp open unknown

This challenge was ment to be an easy multi stage challenge, but was apparently a lot harder than intended, cause it only had 7 solves. The challenge contains three levels which require shell access. Since we didn’t want to have hundreds of logins on the system, we created an extra step to get access to the system.
