NMAP (Network Mapper)
In previous article we discussed about Scanning Phase. Now we will use tool called Nmap for our lab purpose, and we will see basics on NMAP. Basically, it is open source software that runs in all
platforms. It is Character User Interface(CUI) / CLI (Command Line Interface) based tool. Zenmap is its Graphical
User Interface(GUI) version.
# Some Features of NMAP
- Map out IP filters, firewalls, routers, and
other obstacles.
- Determine available(active) hosts on the networks.
- Shows which Operating System(OS) is working in
System.
- It helps to find vulnerable point of OS and
other too.
# How to use This tool ?
To make it basic & simple to students, I'm going to demo this lab on windows. However, if you want NMAP video tutorial on discovering vulnerabilities in advance, then please follow this my link in youtube channel
Let's begin . . .
Step 1: Download nmap for windows from here.(link:
https://nmap.org/dist/nmap-7.50-win32.zip)
Step 2: Extract that folder in Desktop. (or your own desired directory).
Step 3: Open Command prompt and go to nmap
directory.
(Step by Step walk-through by Saurav Bhai)
Step 4: Type nmap

(After that it will shows all usages of it as
shown in below)

Step 5 : To scan particular ip, type
nmap ip (nmap 192.168.1.104)
- When we run above command for particular ip, we will get port, services associated to that port and status of port (open,closed,filtered). Also note at bottom of result, <1 host up>
Step 6 : OS Detection, type
nmap -O ip (nmap -O 192.168.1.104)
Well, these are basics on NMAP. However, if you want NMAP video tutorial on discovering vulnerabilities in advance, then please follow this my link in youtube channel
