1
00:00:00,690 --> 00:00:03,510
Before starting our hacking practicals.

2
00:00:03,510 --> 00:00:07,430
First, we have to configure the networking for our virtual machines.

3
00:00:07,440 --> 00:00:15,000
As you can see, by default it is selected to net network, which is not good because it means all of

4
00:00:15,000 --> 00:00:18,420
our virtual machines are sharing the same IP address.

5
00:00:18,600 --> 00:00:19,200
Right.

6
00:00:19,530 --> 00:00:24,780
So to change this, we have to select Net Network, right?

7
00:00:25,170 --> 00:00:29,040
As I'm going for Net Network, it's showing me Net Network as a name.

8
00:00:29,310 --> 00:00:34,200
Right, because VirtualBox automatically created this network.

9
00:00:34,200 --> 00:00:34,830
Right.

10
00:00:34,950 --> 00:00:36,900
But sometimes it won't.

11
00:00:37,380 --> 00:00:38,880
You will see nothing here.

12
00:00:39,060 --> 00:00:49,440
So in that case, what you have to do is go to file, then preferences, go to network and click this

13
00:00:49,440 --> 00:00:53,940
icon, which is as new net as you click this.

14
00:00:53,970 --> 00:00:56,520
See, there is a new network created right.

15
00:00:56,520 --> 00:00:58,680
And to remove, click this.

16
00:01:01,100 --> 00:01:01,640
Right.

17
00:01:02,510 --> 00:01:03,080
Then click.

18
00:01:03,080 --> 00:01:03,730
Okay.

19
00:01:04,550 --> 00:01:05,600
Come again.

20
00:01:07,440 --> 00:01:13,710
And now you will see a list of all of the net networks that you have created.

21
00:01:14,130 --> 00:01:14,730
Right.

22
00:01:15,750 --> 00:01:18,720
So this is the perfect option for networking.

23
00:01:18,750 --> 00:01:21,160
Now what's happening behind the scenes?

24
00:01:21,180 --> 00:01:29,370
See, after selecting Net Network, all of our virtual machines, things that our host machine that

25
00:01:29,370 --> 00:01:32,130
is my physical machine is a router.

26
00:01:32,640 --> 00:01:33,210
Right.

27
00:01:33,900 --> 00:01:39,720
By choosing net network, my physical machine will act as a router for all of my virtual machines.

28
00:01:40,380 --> 00:01:45,600
Because virtual machines cannot directly access to my actual router.

29
00:01:46,530 --> 00:01:49,830
So this is how we can configure our networking.
