Hello everyone. So in the previous video we saw how
you can perform the scan on the
whole network and identify which hosts are
up into your network. So in this video we are going
to see the same scan, but we are going to tune the scan
to give the output much more faster.
So we already know that nmap uses and scans
1000 ports.
By default, but we are going to use a fast
scan to scan only 100 ports,
which will give us the results faster compared
to the normal scan.
As you can see on the terminal I have given the
same command. But this time I have added hyphen f
flag which stands for fast scan.
As you can see the scan has started successfully and this
time and map is only scanning for hundred ports.
So
we will get the output very quick. Can you
see we got the output in 9.3636 seconds
only about whatever devices were up
into our Network.
So I hope you guys understood this and
you can utilize this to do a quick scan
and understand the overview of your network, which
devices are up and down. Thank you.
