Lab 18: Port Scanning

 

Objective

To get experience scanning ports.

 

Overview

In this lab, you will use the nmap tool to scan a remote system. Make sure it's installed on your virtual machine. The nmap man page has excellent information on port scanning, which you should consult in going through the lab questions. The sections labelled "Port Scanning Techniques" and "OS Detection" will be especially helpful.
