1
00:00:05,210 --> 00:00:05,480
Now.

2
00:00:05,480 --> 00:00:09,430
There's no better way for you to learn than to follow along practically.

3
00:00:09,440 --> 00:00:15,800
So make sure that you've got Wireshark downloaded and installed and that you open the Pcap files that

4
00:00:15,800 --> 00:00:17,510
I've attached to this course.

5
00:00:18,020 --> 00:00:23,390
Now I'm going to demonstrate stuff practically using Genesis three, but rather than you trying to build

6
00:00:23,390 --> 00:00:29,600
this topology and replicate what I've done, you can simply download the Pcap files and then follow

7
00:00:29,600 --> 00:00:30,230
along.

8
00:00:30,260 --> 00:00:35,360
The Pcap files that I'm sharing are the actual captures that I'm going to do now.

9
00:00:35,450 --> 00:00:42,530
So you'll be able to follow along and also use Wireshark to see the results that I get in this topology.

10
00:00:42,530 --> 00:00:46,130
I've got two Windows PCs, PC one and PC two.

11
00:00:47,740 --> 00:00:48,040
See.

12
00:00:48,040 --> 00:00:49,150
Here's PC one.

13
00:00:49,180 --> 00:00:50,530
Yes, PC two.

14
00:00:52,740 --> 00:01:03,060
PC one has IP address ten 111 default gateways ten 11254 which is the router in the topology PC two.

15
00:01:05,180 --> 00:01:13,990
As IP address ten 121 default gateway is ten 12254 which is the router in the topology.

16
00:01:14,000 --> 00:01:21,050
So I'm simulating an entire network here in June is three and I'm going to show you how to capture packets

17
00:01:21,290 --> 00:01:26,570
or capture frames and we'll talk about those terms in a moment and then you'll be able to see what's

18
00:01:26,570 --> 00:01:27,290
going on.

19
00:01:27,560 --> 00:01:30,200
I've also got a server in this topology.

20
00:01:30,200 --> 00:01:36,080
The server is a web server, FTP server, t ftp server and runs other services.

21
00:01:36,080 --> 00:01:40,850
So what I'll do is send traffic from the hosts to each other.

22
00:01:40,850 --> 00:01:45,530
So PC one to PC to back again and also from the PCs to the server.

23
00:01:45,800 --> 00:01:51,800
And then have a look at the captured packets and hopefully you'll be able to see what's going on and

24
00:01:51,800 --> 00:01:57,530
get an understanding of the frames, packet segments and so forth, and also get an understanding of

25
00:01:57,530 --> 00:01:58,880
how to use Wireshark.
