Nmap - Finding Open Ports, Services and its Versions + more Juice Info!!

If you are in a restaurant, chances are you are going to order something to eat.

Nmap does more than just scanning for ports, it can also scan the system for the version of the services running against that ports. There are many scanners to do that but i prefer Nmap personally because of its lightweight.

So a typical Nmap scan without any switches will find the open ports and the services running against it. Below is a standard output of a successful completed Nmap scan.

If we want to see more juicy information in detail and the versions of the services running on them, simply input the switch A to the command. A simple switch gives a huge difference.

Look at the details (in the yellow box) of what Nmap -A can provide:

In time to come, i will show how Nmap -A in conjunction with other switches to display more details than i imagined before.
