Nmap : Null Scanning Tutorial

Hello, this is my second post. Today i will show you how to Scanning port using nmap with null scan technique.

1. You need to know your ip addres, you can type “ifconifig” in to your terminal.

for example this is SS from my pc.

2. Then open your terminal and type “nmap”.

Nmap (Network Mapper) is a security scanner originally written by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich) used to discover hosts and services on a computer network, thus creating a “map” of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes the responses. (wikipedia).

When you type “nmap” on your terminal you can see all the options for scanning.

3. In these case i use null scanning technique (-sN) + (-v) for Increase verbosity level.

192.168.1.0/24 is for to know all of host address. 

4. Just wait for a minute and taraaaa this is the scanning result! 

Okay, thats all from me. Thanks for your time!
