00:00:01,040 --> 00:00:03,758
Ok, now that we have Kali Linux installed,

2
00:00:03,760 --> 00:00:10,340
I want to give you a basic overview of this operating system in this lecture, so that you're comfortable with it

3
00:00:10,540 --> 00:00:15,740
and we're going to be using it throughout the whole course so everything is going to become easier for you

4
00:00:15,740 --> 00:00:17,240
as we go through the course.

5
00:00:18,620 --> 00:00:21,800
Now the first thing that I want to talk about is the status bar in here,

6
00:00:22,460 --> 00:00:25,680
so, you can see we have an applications menu in here

7
00:00:25,940 --> 00:00:30,540
and inside it you can see all the applications are categorized.

8
00:00:31,380 --> 00:00:37,780
So we have information gathering applications, vulnerability analysis, web application analysis,

9
00:00:37,780 --> 00:00:40,500
reverse engineering and so on.

10
00:00:41,440 --> 00:00:46,260
So you can go on each one of these entries and just select any program that you want to run.

11
00:00:47,580 --> 00:00:51,080
And the next menu that we have is the places which shows you

12
00:00:51,080 --> 00:00:53,840
the most common places in the file system.

13
00:00:54,320 --> 00:00:58,460
So we have home, we have the desktop, we have the documents, downloads and so on.

14
00:00:59,600 --> 00:01:02,960
So you can access the places from here and then you click on 'home'

15
00:01:03,360 --> 00:01:06,757
or you can just click on the files icon in here on the left

16
00:01:06,760 --> 00:01:12,800
and both of these will bring you to the home directory, which is actually the root directory.

17
00:01:13,100 --> 00:01:21,980
So it says home in here but the actual location of this, if I do 'Ctrl + L' , you'll see it is '/root'.

18
00:01:23,100 --> 00:01:26,760
So inside this you can see we have our downloads, music, pictures,

19
00:01:27,040 --> 00:01:30,080
similar to the way that you'd have it in Windows and OS X.

20
00:01:31,340 --> 00:01:36,520
We also have the time in here and in here on the right we have more controls,

21
00:01:36,700 --> 00:01:40,400
So the first thing that we have in here is the workspaces.

22
00:01:40,820 --> 00:01:44,240
So Linux comes with multiple workspaces by default.

23
00:01:45,040 --> 00:01:49,200
Basically what this allow us to do is we can have this desktop in here

24
00:01:49,200 --> 00:01:54,420
for example we can open the places and we can, for example, navigate to downloads

25
00:01:54,420 --> 00:01:55,860
and do some work in here.

26
00:01:56,680 --> 00:02:01,720
But if we go here to workplaces and go to the second one,

27
00:02:02,560 --> 00:02:05,980
you can see that I have an empty desktop that I can do whatever I want

28
00:02:06,340 --> 00:02:08,580
and for example I can launch Firefox in here.

29
00:02:10,420 --> 00:02:16,060
And then again if I want to go back to the first workspace, all I have to do is click on here,

30
00:02:16,060 --> 00:02:19,000
click on number one and I'm back in here.

31
00:02:20,140 --> 00:02:26,480
And because I've already used up two spaces, the system is already creating a third empty space,

32
00:02:26,480 --> 00:02:31,440
so I can click on that and as you can see I'm in the third space, where I can do more stuff.

33
00:02:32,680 --> 00:02:38,932
Now you can also navigate between the spaces by pressing 'Ctrl + Alt + up or down',

34
00:02:39,480 --> 00:02:41,559
to go up and down in the spaces.

35
00:02:42,580 --> 00:02:47,900
The next part of the status bar is this last part in here and if you click on it

36
00:02:47,900 --> 00:02:51,080
basically the first thing it'll allow you to do is control the sound.

37
00:02:51,700 --> 00:02:57,040
Next you'll see your connections, so as you can see right now and as I showed you before,

38
00:02:57,040 --> 00:03:00,519
this is showing up as if we're connected to a wired network

39
00:03:00,860 --> 00:03:04,440
because I configured this network to use a nat network.

40
00:03:05,500 --> 00:03:10,720
If you have a wireless adapter connected to this computer, you should be able to see it here.

41
00:03:10,940 --> 00:03:15,560
If you don't see it, then follow the link in the resources of this lecture

42
00:03:15,560 --> 00:03:22,470
to see how to properly connect your wireless adapter or any USB device to a virtual machine.

43
00:03:23,420 --> 00:03:31,600
Now I should note, you can only use external USB adapters in order to access Wi-Fi networks from Kali.

44
00:03:31,600 --> 00:03:34,240
You can not use the built-in Wi-Fi card.

45
00:03:34,880 --> 00:03:40,510
But Kali should have internet connection anyway because it is configured to use an ad network

46
00:03:40,510 --> 00:03:44,380
and as you can see in here it's telling
me my wired is connected.

47
00:03:44,900 --> 00:03:48,620
So if I actually go down to Firefox, I'll close this,

48
00:03:50,380 --> 00:03:53,220
and if I just go to 'google.com'

49
00:03:54,280 --> 00:03:56,800
you can see it is connected to the Internet.

50
00:03:57,780 --> 00:04:00,100
So, let's go back to where we were

51
00:04:01,480 --> 00:04:08,500
and if we click here, we also have the battery settings, the user settings,

52
00:04:08,500 --> 00:04:12,920
you have this button to turn off the machine, this is to lock the machine

53
00:04:12,920 --> 00:04:17,720
and this will show the preferences where you can modify the preferences of the machine.

54
00:04:17,720 --> 00:04:23,740
So you have Bluetooth, Wi-Fi, change the background, change the languages and so on.

55
00:04:24,720 --> 00:04:27,500
So you can spend some time getting familiar with this.

56
00:04:27,500 --> 00:04:29,360
It's very easy and very intuitive.

57
00:04:30,060 --> 00:04:34,178
Same goes to the file manager in here, very intuitive, double-click to go in.

58
00:04:34,720 --> 00:04:38,580
You can right click an archive and extract here to uncompress it.

59
00:04:38,580 --> 00:04:43,180
You can navigate throughout these files by clicking them and then you have the trash here,

60
00:04:43,180 --> 00:04:45,420
which contains the deleted files.

61
00:04:47,260 --> 00:04:52,034
Now we also have the dock in here which contains the favorite applications

62
00:04:52,040 --> 00:04:58,780
and you can also access all the other applications by clicking on this icon right here.

63
00:04:58,780 --> 00:05:04,180
This shows applications and this will show you a menu with the most frequent applications

64
00:05:04,360 --> 00:05:09,360
and then if you click on all, it will show you all the available applications.
