Now.
There's no better way for you to learn than to follow along practically.
So make sure that you've got Wireshark downloaded and installed and that you open the Pcap files that
I've attached to this course.
Now I'm going to demonstrate stuff practically using Genesis three, but rather than you trying to build
this topology and replicate what I've done, you can simply download the Pcap files and then follow
along.
The Pcap files that I'm sharing are the actual captures that I'm going to do now.
So you'll be able to follow along and also use Wireshark to see the results that I get in this topology.
I've got two Windows PCs, PC one and PC two.
See.
Here's PC one.
Yes, PC two.
PC one has IP address ten 111 default gateways ten 11254 which is the router in the topology PC two.
As IP address ten 121 default gateway is ten 12254 which is the router in the topology.
So I'm simulating an entire network here in June is three and I'm going to show you how to capture packets
or capture frames and we'll talk about those terms in a moment and then you'll be able to see what's
going on.
I've also got a server in this topology.
The server is a web server, FTP server, t ftp server and runs other services.
So what I'll do is send traffic from the hosts to each other.
So PC one to PC to back again and also from the PCs to the server.
And then have a look at the captured packets and hopefully you'll be able to see what's going on and
get an understanding of the frames, packet segments and so forth, and also get an understanding of
how to use Wireshark.
