Assignment Tasks:

Step 1: Find the target IP (Reconnaissance)

Open your terminal and run:

nslookup scanme.nmap.org (Returns the IP of the given domain)

Step 2: Run the required nmap scan and save the output in a text file (file name with your VU ID)

Run this command:

nmap -sV -p 22,80,443 <Target_IP_Address> -oN bc11223344.txt

Note:

Replace <Target_IP_Address> with the IP address returned from step 1.

Replace bc11223344.txt with your own VU ID filename.

Step 3: Display the scan output (using the cat command)

cat bc11223344.txt

Note: Replace bc11223344.txt with the actual file name (your VU ID) saved in Step 2.

How to submit the assignment solution:

Submit an MS Word document (.doc or .docx) containing only two screenshots showing:

Output of the nslookup command and output of the nmap scan showing open ports and running services
Output of the Cat command showing the contents of the txt file saved in step 2

Note: Replace bc11223344 with your actual VU ID. If two submissions have the same ID, zero marks will be awarded to both students.
