Hello everyone. So in this video we
are going to see no randomize or
sequential type of port scan.
So to do this scan the syntax is and map
the target IP address hyphen small
r
Which stands for no randomize or sequential and
hyphen V to see the
output in verbose mode?
So you can scan a Target Port number using
no randomized Sports scan and nmap
will start scanning the TCP and UDP
ports in a sequential manner.
So the port scanning will go in a
sequence manner with starts from 1
to 3, and it will go till 65,535
ports.
So you can always add a hyphen V to see the
verbose output the example of
do this type of scan is nmap. The
IP address followed by a small hyphen R.
So let's see this practical in action
over here onto my screen.
I'm going to type a command, which is nmap.
the target IP address that I want to
scan
followed by
hyphen, small R which stands for no
randomize
as you can see and map by default performs.
top 1000 port scan, but you
can see the output over here is in a
sequential manner as you can see first is
21 then 22 80
1 1 1 9 8 7 6
So in this way, we found out that if
you want to do a port scan into a
sequential manner, then you can do it this
way.
So let's try to do one more scan of nmap of
scanme Dot nmap.org.
In this you can see the port scan has again started
and it will perform in a sequential manner
again.
As you can see the ports that we have identified which are
open are these 422 followed by
80 139 445 9929
3 1 double
37. So these are the port numbers which are
shown but in a sequential manner.
So I hope you guys understood how you can perform this type
of scan.
Thank you.
