And map no port scan.

2

Of course and map is a program that's used to perform active scans.

3

And the discovery of the results will help you set your goals for what your pen test will be.

4

It's gonna be unnecessary to scan all the ports for each IP especially when scanning large networks

5

instead.

6

Wouldn't it be quick and logical to detect open computers as first step and then only scan for ports

7

on those computers Yeah.

8

So let's do this then and map can perform a ping scan just to detect the computers that are turned on

9

so scanning with S N consists of an ICMP echo request DCP send to port 443 DCP back to port 80 and then

10

ICMP timestamp request by default only send packets are sent to Port eighty and four for three on the

11

destination by a non privileged user so let's uh let me show you an example.

12

So let's make an active discovery on the network where the virtual computers are that we have established

13

so over this let's open all of the virtual computers that we have install open virtual box open Kelly

Linux 10 0 dot to dot 1 5 open meadows plausible 10 dot 0 dot to dot for open in 1 to 10 0 down to that

15

16

open up terminal and write this command and map as in ten down zero dot to dot zero slash to four and

17

press enter okay.

18

So here the scan results and we can see the computers that are open here.
