Everyone, welcome back to the
course. So in the last video, we
just ran a quick acknowledgment scan
with ping three.
Again, we were just looking at the
percentage of packet loss
in this video. We're going to run a
Christmas scan.
So, again, we have to run
this against Kelly Linux.
We're actually going to run it here
in the terminal.
We'll run the command.
And then we have a couple of
questions in the long run, one
additional command.
And then in the next video is
actually the last component of this
particular lab where we'll just
do some more Windows firewall
changes and then we'll run another
scan against that.
So let's go ahead and get started
here. So we've got a terminal window
here. I'm just going to go ahead and
type in clear like I normally do,
just to clear things up and hit
enter just to make it where we're
starting fresh.
And then we're going to type in this
command here. So it's pretty long.
It will go step by step through it.
So we're going to type in three
space dash lowercase C
space, the number one
space dash capital V
as in Victor space dash
lowercase P space 80
to specify port 80.
Space dash lowercase s
space 555.
To specify that we want to the
initiating port is going to be
the port sending packets.
It's going to be port number five
thousand five hundred fifty five.
We're going to put another space and
then a dash dash capital M
excuse me to set the TCP
sequence number or put a space in
the number zero.
We'll put another space, a dash
capital you p f
to set the urgent push and finish
legs and that will put a space.
And then finally our IP address
again, the same IP address we've
been using for most of the SLAPP
or so as I mentioned, we're going to
do this step by step so everyone can
type in the correct command here.
So we'll start off this by typing in
three space dash
excuse me, space dash lowercase C.
So it's paying three space,
that's case Casey will
put another space there.
Now we're going to type in the one
and then a space dash capital
V.
So we'll put a one space dash
capital V.
We're going to put another space
here and we're going to put dash
lowercase P to specify
number eighty. And then we'll put a
space in the will, actually put the
eighty four point eighty.
Next we're going to put a space,
we're going to put a dash lowercase
s. So if you remember,
we want to specify that we're
sending it from number five thousand
five hundred fifty five
and we're just going to put a space
in our actual number that we want to
use the 555.
We'll put another space,
then we're going to add in the dash
capital M and space in
the number zero so
that we'll put another space
and then we're going to put in Dash
UPF.
And then finally our IP address,
we're going to put all that into one
shot.
So dash pf
space one hundred two point one
six eight zero one.
And again, you can just double check
yourself if you want to make sure
that you're running that correctly.
But you should get an error message
if you're not.
And we'll go ahead and run this
command by pressing internal
keyboard here. You'll see it comes
back pretty quickly.
We have a few questions here.
So question number one, how many
packets does it show it sent
successfully?
And then how many packets were
received successfully?
So questions one and two.
They're.
All right, so at least on my end,
and you should actually have the exact
same results we see that one package
was transmitted and one package was
received. So we were basically a
hundred percent successful on that
one.
So going back to our lab document
here, we have one more command we're
going to run and we're basically
running a city scan again.
So again, the TCP three way
handshake.
We're talking about that first
portion where I say, hey, I want to
talk to you and then nothing
else happens. Right? I just keep
continuously saying, hey, I want to
talk to you. So kind of like the
creepy guy at the club or something
that's like, hey, hey, hey.
Kind of like that. But we're not
going to be creepy on this.
We're just going to run a command.
So let's go ahead here and we're
going to run this command.
And then we want to find out, is 80
showing us open when we run this
particular command?
So let's go and do that now.
So we're going to type in ping
three.
We'll put a face,
we're going to put a Dash eight and
then a space and the number eighty.
Four Dash eight space, the number
80.
We'll put another space there and
then we're going to put a dash
capital V and then a space
and the dash capital S.
So Dash Capital V.
Space Dash Capital S..
And then finally, we're going to end
with our same IP address, the same
one we've been using that 192 dot
one six eight zero one.
So one of the two one six eight
zero one.
And then just press enter our new
keyboard and that'll go ahead and
run the command for us.
So, again, what we want to find out
is port aid is showing as open.
So let's take a look here.
So are we getting a response
that's kind of kind of the main
question there, right. And that'll
help you decide if the ports
actually open. So if we get a
response, then the answer would be
yes. Right. But if we don't get a
response, then the answer will be
no.
So we see here that, yes,
we did get a response from Port A-T.
So the answer to the question would
be, yes, we did.
You know, yes, it is showing us
open. Yes, we did get a response
from it. So we're good to go
in this lab. We just ran a couple of
quick commands with paying three.
Again, we ran our
Sint Can just a moment ago.
And then we also went ahead and ran
our Christmas scan.
Now, in the next video we're going
to do is do some more.
As I mentioned, Windows
firewall.
We're going to do some modifications
or essentially just turn it on again
and run some scans against it and
take a look at what that output
looks like.
