Hey, everyone, welcome back to the
course. So in the last video, all we
did is we started off with our first
and map command, so we went ahead
and logged into our lab environment.
We went ahead and launched our Kelly
Linux machine and watched the
terminal window.
Initially, we type if and we took
a look at the Ethernet interface as
well as the loop back interface.
And we also grabbed the IP address
of our Kelly machine.
In this video, we're just going to
finish our reviewing our output
of the particular came in, we typed
in, so we talked and map and then we
use a dash lorcaserin flag
again, that was to disable port
scanning. So basically, it's just
sending a ping request for us.
And we scanned a range of the
192 to one six eight zero one
all the way to 254 to see what kind
of information we get back.
Now, you see in the background there
that we didn't get a whole lot of
information back on the particular
command. But we have a couple of
questions that we need to answer
now. Now, if you have not
done this particular command yet and
ran it, you'll want to go ahead,
pause this video in either run
the command or go back to the last
video if you skipped over that one
and make sure you go through the
steps in this lab again.
We've designed these labs as a step
by step process.
So that way you can go congruently
through all of them.
All right, so question number four,
here's where we're at.
So we've gone ahead and ran out and
mapped our case and and
then our IP address command there.
So question number four are the host
up and if. Yes, right down the Mac
addresses.
All right, so are the Hosta, so I
see on my end, yes, I see all these
hoster up and I see the Mac
addresses here for
these particular items.
And so I would jot all those down in
my document.
Our question number five is the host
are up, which we've already
established. Yes, they are.
What are the IP addresses of those
hosts?
All right, so again, we see that we
have all of our IP addresses that we
found, so here we've got our
initial one here are calling Linux
machine.
And then we've also got one two one
six eight zero to one
nine two one six eight zero four
five 250,
et cetera.
Let's go back to our lab document.
So now we're going to run a command
that basically disables host
discovery again in the downloadable
resources. I have a listing of and
map commands as well as the
specific commands.
I want you to practice as kind of
part of the assessment portion of
this course.
So all we're going to do at our
terminal window here is we're just
going to type in this command here,
the end map dash capital,
P lowercase, and then
again, the same range of IP
addresses.
Now I'm going to go ahead and type
clear in my terminal window just so
I can clear it up and make it a
little prettier. You don't have to
do this step, but if you want to
follow along and do it, just type in
the word clear and then just press
enter. You notice that it clears
everything. It starts is back at
essentially the beginning when
everything looked fine.
All right, so as I mentioned, we're
going to go ahead and type in this
command here and map dash
capital P, lowercase N and
then our IP address range.
So let's go ahead and do that now
and map all lowercase
space, dash capital P, lowercase
N, we'll put a space
and then our IP address range.
So again as one two one six
eight done zero one
forward slash twenty four
and we'll go ahead hit enter on a
keyboard and run that as well.
And I'm going to go ahead pause
video here and just take a moment or
so to run this and we'll pick things
back up once we have the results.
All right, so we have our results
now. We went ahead and ran our scan
to disable host discovery, so we
have some results on the screen
here. So let's take a look at our
lab. We just have one quick question
here. What response do you actually
see?
Ah, so what I see is I see that it's
provided by some ports that
are open. It shows me that there's
some closed ports there that I don't
necessarily care about too much,
at least for the purposes of our
lab. But I do see that there are
some open ports here.
So I know that. OK, well, they are
running S.H.
or they at least have that open
perhaps. You know, there's some way
I can attack through that, you know,
and again, thinking back to the
criminal hacker mentality of
why, you know, why we're actually
scanning stuff. Right.
We're trying to find potential
ways into these systems.
All right, so let's go back to our
lab document here.
So now we're going to do our last
step of this particular lab.
We're just going to run a quick
command.
And with this command, we're
basically just doing a ping ping
scan. So that's what this dash
one switch will do for us with each
ping three.
Now, if you're studying for something
like this certified ethical hacker
exam for council,
you just want to know commands
like and mapping each ping three and
kind of understand the different
flags in use if you're
studying for, like, compter
contests. Plus that you'll also want
to be able to look at like an output
like this, for example, and
understand what command was run
to get to this particular output.
So just keep that in mind, some
differences in those particular
exams and we'll keep moving forward
with our lab so we
are still allowed to do our Calli
machine. We haven't changed at all.
If you have closed it for some
reason, definitely log back in and
get going with a terminal window and
you'll be caught up.
I'm going to go ahead clear again
just to clear the screen.
And then is president turning on my
keyboard and you'll see it'll clear
the screen for us. So we'll go ahead
and run our last command here.
So again, we have our paying three
space dash, one space
and then our IP address here.
I subscribe to that and so aping
three.
Space, that's one
space and then our IP address, so
the one hundred two to one six eight
zero dot one.
And if you need to pause a video to
type that in, feel free to use this
one right here.
All right. So let's go ahead and run
this command by just pressing
internal keyboard.
And again, this one might take a
moment or so to go ahead and finish
out. It's usually pretty quick.
So I'll kind of hang tight here and
we'll see if it'll crank it out for
us quickly.
And then once it completes, I
just want you to note
if you see any type of response at
all.
So may go for a just another moment
or so here, I'm going to go ahead
and pause the video and we'll take a
look at once it's finished out.
All right, so we just ran our big
three command and it was taken just
a moment. So am I.
And so I just actually utilize
control C to cancel it and
stop the scan.
And you're welcome to do that on
your end as well as if you're still
going.
But so the main question here on
this one is, do we see any response
at all?
And the answer is yes.
Right. We do see that we get some
kind of response from the particular
IP address. We also see our time to
live, et cetera, et cetera.
So with this one, we were just
trying to see if we get any response
at all. Again, this lab was just
checking for life systems.
So for our purposes,
we were able to see that, yes, all
the systems that we were touching
were alive and we saw the IP
addresses were getting response from
were live systems.
And so potentially moving through
the additional scanning and then
eventually enumeration aspects,
we could potentially find
vulnerabilities on those systems and
exploit those to gain access and
then from there move laterally
through the network or steal data or
whatever our final objective might
be.
So this video, which is covered,
live system, you know, checking for
life systems in the next lab,
we're going to talk about and
basically do some more and map and
ping three commands, specifically
checking for open ports.
