Hey, everyone, welcome back to the
course. So in the last video, we
just went ahead and ran our second
and met command, so we combined
three different IP addresses, one of
the two one six eight zero
one than we did 10, as well as
that one hundred.
So that was step 16 of our lab.
So now the results are complete.
So question number two here, are
there any ports displaying for
the particular IP addresses that we
ran the scan on?
So you can easily see in the
background there for me at least,
that, yes, I see all sorts of ports
open, so I see them open
on the dot.
One address for us.
All right, so the last step of our
lab here, we're going to actually
just run the ping three command,
so I'm going to go ahead and clear
my terminal window here to make it a
little easier to read.
You're welcome to do so as well.
Or you can just levers as is.
It doesn't actually affect the
output of the command we're running.
So to clear my screen, I'm just
going to type in the word clear and
then just press enter and you'll see
all the commands I previously typed
disappear for us.
All right, so the command we're
going to run here is going to be HPN
three, Dash eight,
which is basically just enabling the
scan mode that we're going to give
it a range of ports to scan.
We're going to scan it with a
CINCPAC sort of sending the sin flag
or we're setting the same flag,
excuse me, and then we're just going
to do going to do it against just
one IP address.
So that main IP address that we've
been using throughout this entire
lab, our Cisco
and type, that is we'll go step by
step here.
So HPN three,
we'll put a space and then we're
going to type in the Dash eight,
and then we're going to put a space
and then type in zero, dash five
thousand. So let's go and do that.
Now we're going to type in
dash eight, space
zero, dash five thousand.
Again, we're specifying the range of
ports that we want to scan.
We're going to put another space
and then we're just going to type in
a dash capital S..
Again, that the tell
it that we want to do is scan
and then our IP address again.
Then we've been using this entire
time.
So Dash Capital s,
we'll put another space and then our
one only two one six eight
zero one and then just press
and turn your keyboard.
Now it might take a moment or so to
pull back the results.
You'll see it gives us some results
right away there.
So we can actually go ahead and
answer our question on our lab as
it's finishing running.
So the question is, are there any
ports not responding?
So let's take a look at our output,
you see just takes a few seconds to
actually run that command.
So we see all these different point
numbers here.
Well, let's scroll back up a little
bit and see what does this actually
mean? What are these poll numbers
right here that we see?
Are these open or closed?
Where are they not responding?
Let's see here.
So my take a moment or so to come
all the way back up and their
results here.
But basically what we're looking for
is it's going to tell us that all
these numbers we're seeing down here
near the bottom section of the
output, this is all going to be
ports that are not responding.
So let's go back up here.
We should be almost there.
And you'll see some of them are
labeled like open VPN, et cetera.
Many of them are not labeled.
They're just random ports.
All right, so you'll see here as we
scroll back up, you'll see not
responding.
Right there.
And that's what we're looking for.
So here in question number three,
are there any ports not responding?
The answer, of course, would be yes,
there. And if you wanted to put all
these port numbers down, you
certainly could do so.
It's probably quite a bit.
So it's it'll take you a moment,
certainly. And then if we scroll
back up a little further, we can see
all the ports that are responding to
us and the services running on those
particular ports.
All right. So this lab, again, we
were just looking for some open
ports again, just a little bit of
hands on practice to
take a look at those things.
It's part of the scanning process
that we would normally be doing.
Again, the intent, of course, is to
find vulnerable systems
in a way into the network.
And that way we can compromise and
move forward with whatever our
nefarious goal is from there.
So in the next video, we're just
going to go over some more scanning.
So we'll take a look at that in the
next module.
