Challenge description:

Use your skills to check out the host

The key to this flag is knowing whats open and what is closed. Once you are certin of the open ports, you will need to creat the flag in the correct format. The following is an example of the flage if tcp 8080 and tcp 80 and udp 1701 and tcp 21 are open the flag would be: CTF{tcp8080:udp1701:tcp80:tcp21}

ctf-id-3.lcps.k12.va.us

Solution

This is a simple port scan.

$ nmap ctf-id-3.lcps.k12.va.us
