Lab – Scanning and enumeration

To begin, start up your lab environment, including the Kali Linux and the Metasploitable machines set up in the previous lab. When all the machines are booted up, log in to your Kali machine with the account name kali and password kali.

   • Run the sudo nmap -sn 192.168.255.0/24 command
2. Explain what the –Pn switch does:
   • Run the sudo nmap –Pn 192.168.255.2 command
