Enumeration

As usual, we start off with a basic nmap scan to discover open ports and services.

Evidently, nmap is telling us that it is a Debian machine (Linux-based) and SSH is open on port 22 and there is a web server running on port 80.

Rather interesting to see that there are some mention of OSTRICH and EMUEMU. We will keep that in mind for now.
