Hello everyone. So in
this video we are going to see the nmap port
ratio scan.
So the syntax of doing this scan is nmap the target
IP address.
Followed by hyphen hyphen ports hyphen ratio and
hyphen V to see the output in
verbose mode so you can scan a target's
port number using Port ratio scan.
So when you run this scan, it scans all the ports
in the nmap services file with the ratio
greater than the one which is given remember
you can give the ratio between 0 and
1.
Okay.
You can always add a hyphen V flag to see
the output in verbose mode the example
of doing this type of scan is nmap. The target IP
address followed by - ports hyphen
ratio.
So let's see this type of scan in action as you
can see on my screen. I have typed the command which is nmap
the target IP address -
Port hyphen ratio and hyphen V to
see the output in verbose mode, so
Here when I will hit enter I will be able to
see the status of the ports.
Which is over here like this.
If I just type - F and open then I'm only
able to see the open ports out of those ports
as you can see.
The port ratio scan. There are eight three
one five close ports Okay,
so
We got to see one two, three four and
five total open ports. So
which means this in this can total
eight three two, zero
ports were scanned out of which
we identified only five were open.
