Hello everyone. Welcome to another video from section 9.
And I think in this video I'm
going to talk about opening a circuit in a Linux machine
in a section 9 with your 9.2. So
we're going to answer three questions and more corrosion also
work in our lab. I showed it comments. But let's have
an overview. Is it going to the network consumers as a communication and
points? So it's provide a connection between two into dies.
Their wish to communicate with each other order. A
within a network. For example, your limit.
And a Target or a Windows inert server or
your network. So going to use on a TCP IP
stack transport earlier. I used to send and
receive the data packets in this video.
And in this recording today, we'll explain later date to,
you know, the difference M of listing down,
although open circuits that are listening on the
Linux, or your machine.
So there are several methods that we're going to tell
you two of them, that's usually works
an orbit, attend and other ones.
So for this thing called open circuits your machine, you
can follow the two minutes. The first one is this thing
called open circuit. Listening on a Linux machine on
the, with the SS you to lie. So, if you want to
list down all the ports, and all the circuits listening on the
Linux Mint or your any machine
you using any
Always using that's based on your decision.
We are using calendars here regardless
of which into our internal protocol layering using. So
then you can eat or execute a comments. Then
I'm going to tell you the next slide. So let's go
travel app.
Well, the first comment and I'm going to use as I say
SS.
And dash.
that, she'll
OK, Google intern and we
can see the result here.
We're real.
Also, you can hear the others and import, colonel colonel and
all the usages.
And receive a kiwi, the process.
Aries path.
And I see all the information for example, some of
them are listening.
Usually they are using it. So well, I'm
going to kill the bridge and go into the second method that
we're going to use. If you want to list down all the
up in TCP sockets listened on a Linux, your
machine.
Then you need to execute this coming up and show you and
use cat or more or less
common. So I'm just going to use more
categorical going
to be a process and net.
And then TCP, for example.
All right. Where is it? If you want to
see it, another way you can also use another for
any editor that you want. There.
Is it?
Also this clip page. Again. This
comment will show that although
participate so gets their own single Linux. So
in the next one, I'm going to show you how to see
the UDP actually. So
it's exactly the same as this one. Just did
you disappear to European your? Is it?
We can use that.
Cat comment as well.
We are here to result.
So in this video, we shared three minutes that listing
all the down open circuits this in Ghana Linux. So
the first models are all the listening. So get
your goal is over Internet Protocol. There are following and the order
to on a CPM, UDP protocols. So but
we have another subject to pay attention to
it.
Just some of the comments that you want to know that
Willis dash s as
you can see here, gonna give you a summary of
the ports. And so because that are open, we
have iron it to total. And one IP, n, 1 IP V6
as May argue earned six,
So I told me about SS is that she'll sample output
should be this by all the ports and
all the opening four ports with the SSS. Come on,
Linux. We have another comment. This
is Dash BL.
To see process named going to click on
went. Well, please have this process named here.
If you want to organize it, you can use a grip common or
for now. It's going to pass it.
So, you know, let's see if it's okay.
So, if you want to who's responsible to opening circuits for, for
example, Port 4949 using NASA's Comet,
you can see like this one, dash LP.
I'm going to use a comment grip to Links basic
grip. Common. You talked about it before. All
right, we don't have it. So, spin out a
port. Maybe this. We have it yet. All right, here
is the result.
All right, we have another thing.
We can use cultural price.
And example. OK
let's first go to the treasury and
I love this. Okay, these are reports that we have.
For example were going to do.
Whatever is okay.
Our stash shell.
So you can get more information about a process like memory users
and use and current working directory. So we
can visit this territory. There I go to the path here and
you can 3
All right. I'm going to back to me page.
So what's happen? If you want to again? See
all the dishabille circus without using the more common
that I told you before or a cat and
to see the doctors. I'm going to use SSL again and danish
team. The Akshay.
We are. So if you want to display all the
Europeans of it's just going to change it to Didi you from
T to you. You we are a
router Peters and the ports would be
C. And if you
want to display all the Unix sockets going
to use this one, use x, here
we are.
Let's have a video summary. First. We have an introduction, a quick
brief on a so, get somewhere. Is it down with me why we needed? So,
I how we check it out with actually, how it
works for your security for your analyzing, explain
the comments. And we saw the comments Works in our Criminal.
The next video we're going to talk about implementing the driver class. Good
luck.
