Perform an Xmas scan on the first 999 ports of the target -- how many ports are shown to be open or filtered?

nmap -sX MACHINE_IP -p 1-999 

There is a reason given for this -- what is it?

Note: The answer will be in your scan results. Think carefully about which switches to use -- and read the hint before asking for help!

HINT: Run this command with the -vv switch enabled. It's good practice to always increase the verbosity in your scans.

Perform a TCP SYN scan on the first 5000 ports of the target -- how many ports are shown to be open?

Open Wireshark (see Cryillic's Wireshark Room for instructions) and perform a TCP Connect scan against port 80 on the target, monitoring the results. Make sure you understand what's going on.
