Long Live Game

I’m learning the program we were going to used tomorrow. I already learn how to use nmap before. With nmap, you can easily sees what port from certain ip address that are opened or closed.

Out goal is to see what kind of vulnerabilities you can find with nmap.

It also count how many closed port the ip address has. It even can see the details for the owner of the IP address like the OS of the owner, NetBIOS name, and more.

Update:

On 25 May, 2018, I tested this nmap with the same IP address and some of the content has changed now.

In this output, it only show one open port which is port 53. Port 53 is Domain Name System or DNS. DNS is a naming system for computers, services, or other resources connected to the internet.

Apparently, other than port 53, port 80 is also open. Port 80 is HTTP or Hypertext Transfer Protocol.

And this is show all about the target details, especially their OS. They are apparently using Linux for their OS and they only have one IP address.

Conclusion:

nmap can be used to see which port is opened or closed. nmap can also be used to see OS devices from your own computer or other computer. You need their ipaddress first.
