Okay, now that we have Kali Linux installed, 2

2

I want to give you a basic overview of this Operating System 3

3

in this lecture, so that you're comfortable with it. 4

4

And we're gonna be using it throughout the whole course, 5

5

so, everything is going to become easier for you 6

6

as we go through the course. 7

7

Now, the first thing that I wanna talk about 8

8

is the status bar in here. 9

9

So you can see we have an Applications Menu in here, 10

10

and inside it, you can see 11

11

all the applications are categorized. 12

12

So we have information gathering applications, 13

13

vulnerability analysis, web application analysis, 14

14

reverse engineering, and so on. 15

15

So you can go on each one of these entries 16

16

and just select any program that you want to run. 17

17

And the next menu that we have is the Places, 18

18

which shows you the most common places in the file system. 19

19

So, we have home we have the desktop, we have the documents, 20

20

downloads, and so on. 21

21

So you can access the places from here 22

22

and then you click on home, 23

23

or you can just click on the files icon in here on the left. 24

24

And both of these will bring you to the home directory, 25

25

which is actually the root directory. 26

26

So, it says home in here, but the actual location of this, 27

27

if I do Control + L, you'll see it is /route. 28

28

So, inside this you can see we have our Downloads, 29

29

Music, Pictures, similar to the way that you'd have it 30

30

in Windows and OS X. 31

31

We also have the time in here, and in here on the right, 32

32

we have more controls. 33

33

So, the first thing that we have in here is the workspaces. 34

34

So, Linux comes with multiple workspaces by default. 35

35

Basically, what these allows us to do, 36

36

is we can have this desktop in here for example, 37

37

we can open the places and we can, for example, 38

38

navigate to Downloads and do some work in here. 39

39

But if we go here to work places and go to the second one, 40

40

you can see that I have an empty desktop 41

41

that I can do whatever I want. 42

42

And for example, I can launch Firefox in here. 43

43

And then again, if I want to go back to the first workspace, 44

44

all I have to do is click on here, click on number one, 45

45

and I'm back in here. 46

46

And because I've already used up two spaces, 47

47

the system is already creating a third empty space, 48

48

so I can click on that and as you can see, 49

49

I'm in the third space where I can do more stuff. 50

50

Now, you can also navigate between the spaces 51

51

by pressing Control + Alt up or down to go up and down 52

52

in the spaces. 53

53

The next part of the status bar is this last part in here. 54

54

And if you click on it, basically the first thing 55

55

it'll allow you to do is control the sound. 56

56

Next, you'll see your connections. 57

57

So, as you can see right now, as I showed you before, 58

58

this is showing up as if we're connected 59

59

to a wired network because I configured this network 60

60

to use a NAT network. 61

61

If you have a wireless adapter connected to this computer, 62

62

you should be able to see it here. 63

63

If you don't see it, then follow the link 64

64

in the resources of this lecture 65

65

to see how to properly connect your wireless adapter 66

66

or any USB device to a virtual machine. 67

67

Now I should note you can only use external USB adapters 68

68

in order to access WiFi networks from Kali. 69

69

You cannot use the built in WiFi card. 70

70

But Kali should have Internet connection anyway 71

71

because it is configured to use a NAT network 72

72

and as you can see in here 73

73

it's telling me my wired is connected. 74

74

So, if I actually go down to Firefox, I'll close this. 75

75

And if I just go to google.com, 76

76

you can see it is connected to the Internet. 77

77

So, let's go back to where we were, and if we click here, 78

78

we also have the battery settings, the user settings, 79

79

you have this button to turn off the machine, 80

80

this is to lock the machine, 81

81

and this will show the preferences 82

82

where you can modify the preferences of the machine. 83

83

So, you have Bluetooth, WiFi, change the background, 84

84

change the languages, and so on. 85

85

So you can spend some time getting familiar with this, 86

86

it's very easy and very intuitive. 87

87

Same goes to the file manager in here, very intuitive. 88

88

Double click to go in, you can right click on archive 89

89

and extract here to uncompressed it. 90

90

You can navigate throughout these files by clicking them 91

91

and then you have the trash here, 92

92

which contains the deleted files. 93

93

Now, we also have the doc in here 94

94

which contains the favorite applications. 95

95

And you can also access all the other applications 96

96

by clicking on this icon right here, the show applications. 97

97

And this will show you a menu 98

98

with the most frequent applications. 99

99

And then if you click on all, 100

100

it will show you all the available applications.
