All right, welcome back, everyone.
This is the situation where we'll be understanding about why or why shark interfaces.
All right, so let's get started
again.
Come to the search site was shock.
And what's really happened in the very first glance?
You get an option.
Of course, the wash welcomes you, but you also need you also need to select interfaces.
There are a list of interfaces mentioned from local connections from the land to Bluetooth network to
VMware.
And after we have one and Wi-Fi, then there's there are a couple of more as well.
So you see that this is really interesting because a shock doesn't matter as it is, it only Dilan or
Indurain circuits for Wireshark.
It could be any any connection.
It could be any network.
It could be a Bluetooth network.
It could be USB, it could be lan, it could be wi fi, anything.
So so what we can actually do is we can select any one of them that we are interested off and we can
get started.
So let's say we are interested about Wi-Fi and we select the Wi-Fi circuit here.
And the moment we do that, this dog getting on the back.
Coming up, you see that the live streaming of all the packets on the IP packets through and it has
been started now.
And what you can do is you can stop it at any moment you want to.
OK, so let's say at this moment I decided to stop the stream.
So my sharp symbol is highlighted.
The moment you started again, it would say if you want to save your packet, capture the earlier capture
or not, if you can continue without saving, it will get started as well.
Now you can again stop it.
It's that simple.
It is OK.
Now, on the right hand side, you get a capture the options that you will find input and output options
to.
And that's where you can modify your interface settings as to ASBA.
So this is where, again, you see the list of all the interfaces.
If you and if you did select any of the any of the interfaces from here, you won't see them in the
in the beginning.
OK, so let's say if you are only interested to wi fi network, every time you log into your wireshark,
you can select those and select the rest of them.
OK, and you can manage them as well by making sure which interfaces you are really interested about.
And again, the same stuff you can get to know about which, Nikitas, they're there for any name as
well.
You can modify their name as well and you can apply some default capture before further.
I mean, by applying any of the finger, maybe, let's say whenever I log in to wherever I want to see
only the traffic related to this one.
OK.
So if I start this, all the traffic, all the capture to start happening for this interfaces and I
get to see the captured traffic for all this interfaces but this specific figure.
OK, so this is what this this would Wireshark capture.
It interfaces basically gives you an idea.
One more very important thing, and you might come across a situation where you want to capture the
lookback interface traffic.
What is that Lubeck interface, especially especially in the Windows.
It's basically software interface, just like with the routers and switches and other devices we have
to invoke in the firewall as well.
We have to create a new back interface, which is nothing but a software interface with the IS because
it never goes down like any physical interface.
You can rely on it and loop back interfaces is the it's something which where the all the internal communication
basically happens.
So whenever you want to monitor those traffic in case of windows, you have to add the Windows interface.
For that, you have to go to the hardware section and device manager as well.
You can do that.
And from there you can add the hardware and you can select windows there that and you can get to see
the.
Oh, no, not really.
You have to start with the network adapter and from there you have to select windows and then you will
get an option to add the loop back.
Once you do that, your loop back interface will be life and ready to use.
So this is about the Wireshark interfaces.
I, I hope you got the idea.
Now, in order to go out further, it is very, very important to understand how the how the networking
really works, including the.
Protocol stack from beginning to the end, from the physical layer to the application layer, you have
to understand every piece of it.
So we'll get it sorted from there.
And we'll catch you in the next lecture then.
Thank you.
