As he booted up his virtual machine and launched the game, Ethan's excitement quickly turned to frustration. He couldn't wait to dive into the simulated network and start scanning for vulnerabilities using his trusty tool, Nmap. However, as he typed the command nmap -sV 192.168.1.100 (a simple SYN scan to detect open ports and services), he was greeted with an error message that made his heart sink: hacker simulator nmap not working work
