What is Nmap?<\/div>\n
Its a tool. A security scanner that is used to scan open ports, discover host and service that are running on the connected network.<\/div>\n
Its an open source. Its used for active and passive foot printing.<\/div>\n
<\/div>\n
If you have heard footprinting for the first time and don\u2019t know what it is let me tell you what is footprinting and its type.<\/div>\n
Footprinting is a technique to gather information about system or the target. There are two type of footprinting<\/div>\n
1. Passive : Data is collected without owner\u2019s knowledge. Ex:Google, Job portals,Social media, etc<\/div>\n
2. Active : Data is collected by interacting with owner or someone who works for the organisation also known as Social Engineering. Ex: talking with former employee of the organisation or calling receptionist and impersonating as employee who lost his access card or forgot his login credentials, etc.<\/div>\n
<\/div>\n
Now let me show you how to\u00a0 scan in nmap for particular ip.To know ip you can write ifconfig in linux and in windows type ipconfig.<\/div>\n
<\/div>\n
1.\u00a0 This is simple ip scan in nmap<\/div>\n
\u00a0‘nmap (ip address)\u2019 -> Nmap 192.168.225.62<\/div>\n
Note: 192.168.225.62 is my ip address.<\/div>\n
\"\"<\/div>\n
Now let me try with other ip that I have connected to the same network<\/div>\n
\"\"<\/div>\n
So this time ip address will be changed \u2019nmap 192.168.225.159\u2019<\/div>\n
So the result will be as shown in image.Note that there is table which shows ports open and services running on that port<\/div>\n
And also if u are in the same network it will show the Mac address of the device.<\/div>\n
<\/div>\n
\n
2.\u00a0 Now lets say that there are multiple IP address on the network that u want to scan then you can write this command<\/div>\n
‘Nmap <IP address>\u00a0 <IP address>\u00a0 <IP address>’<\/div>\n
Nmap 192.168.225.62 192.168.225.159<\/div>\n
\"\"<\/div>\n
OR<\/div>\n
You can just write all the IP address in one file and just call that file on the nmap command<\/div>\n
‘Nmap -iL <filename.txt>\u2019<\/div>\n
nmap -iL \/root\/Desktop\/test<\/div>\n
\"\"<\/div>\n
\"\"<\/div>\n
<\/div>\n
3.\u00a0\u00a0Now lets go with Aggression scan.<\/span><\/div>\n
In Aggression scan you will get to know the OS used and its version and also scripts running and also trace route scan <\/span><\/div>\n
‘Nmap -A <Target IP address>\u2019 i.e, nmap -A 192.168.225.159<\/span><\/div>\n
<\/div>\n
The result is shown below. <\/span><\/div>\n
\"\"<\/div>\n
\"\"<\/div>\n
Note1:-\u00a0 \u00a0if you are using windows os you can opt for Zenmap, its GUI based and easy to install.<\/span><\/div>\n
Note2:-\u00a0\u00a0I have not covered OS detection and trace route scan and version scan and script as the result will be shown in Aggression scan<\/span><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
