1
00:00:01,000 --> 00:00:01,000
Okay.

2
00:00:01,000 --> 00:00:08,000
So now that we have cubes installed and we booted into it and we logged in and this lecture, I want

3
00:00:08,000 --> 00:00:15,000
to give you a very basic overview of the operating system, and then we'll get to use it more and more

4
00:00:15,000 --> 00:00:16,000
as we go through the course.

5
00:00:17,000 --> 00:00:24,000
So as soon as you log in, you will probably see this window right here, which is a configuration window

6
00:00:24,000 --> 00:00:26,000
for the Unix gateway.

7
00:00:26,000 --> 00:00:34,000
This is the gateway that will direct all the data that we send to the Internet and force it to go through

8
00:00:34,000 --> 00:00:35,000
the Tor network.

9
00:00:35,000 --> 00:00:40,000
Now, before configuring this, I want to give you an overview of the operating system.

10
00:00:40,000 --> 00:00:41,000
Like I said.

11
00:00:41,000 --> 00:00:47,000
So I'm going to keep this to the side because I want to connect to the Internet first before we configure

12
00:00:47,000 --> 00:00:47,000
this.

13
00:00:48,000 --> 00:00:49,000
The first impression.

14
00:00:49,000 --> 00:00:54,000
You'll probably notice that this looks very similar to a lot of Linux operating systems.

15
00:00:54,000 --> 00:01:01,000
You have a status bar in here that shows the running applications and on the left here you have a menu

16
00:01:01,000 --> 00:01:06,000
which allows you to run various applications in this operating system.

17
00:01:06,000 --> 00:01:12,000
You'll notice we can run a terminal in here, which is very similar to Linux terminals, like I said,

18
00:01:12,000 --> 00:01:17,000
and runs a lot of Linux commands plus some cube specific commands.

19
00:01:18,000 --> 00:01:25,000
Other than this, you will also notice that we have System Tools menu which allows you to access different

20
00:01:25,000 --> 00:01:28,000
applications related to the operating system.

21
00:01:28,000 --> 00:01:32,000
The one that you'll be using the most is the Settings manager.

22
00:01:32,000 --> 00:01:35,000
Again, this is very similar to the settings application.

23
00:01:35,000 --> 00:01:41,000
You get on a lot of Linux distros and it allows you to change the various settings of the operating

24
00:01:41,000 --> 00:01:41,000
system.

25
00:01:42,000 --> 00:01:48,000
You can change the appearance, the desktop, the background, the windows, the mouse and keyboard,

26
00:01:48,000 --> 00:01:50,000
the languages and so on.

27
00:01:50,000 --> 00:01:55,000
I've actually used this to modify the font size and the icons and even the theme here on top.

28
00:01:55,000 --> 00:02:01,000
So you'll notice the theme that I have right now is slightly different than what you see on your desktop

29
00:02:01,000 --> 00:02:02,000
if you just install cubes.

30
00:02:02,000 --> 00:02:08,000
The reason why I did this is just to make it a little bit more readable and easy for you to see what

31
00:02:08,000 --> 00:02:09,000
I'm doing.

32
00:02:09,000 --> 00:02:15,000
If you're watching this from a small screen or from a phone, so very simple settings, you can click

33
00:02:15,000 --> 00:02:21,000
on whatever center you want to modify and then you can modify the different settings just like any other

34
00:02:21,000 --> 00:02:22,000
operating system.

35
00:02:22,000 --> 00:02:26,000
So it's very, very intuitive and there is no point of wasting time on this.

36
00:02:27,000 --> 00:02:32,000
Again, in the system tools other than the settings manager, you will find various settings and various

37
00:02:32,000 --> 00:02:36,000
applications that you can use to configure your system.

38
00:02:36,000 --> 00:02:40,000
So you have the package manager where you can install different programs in different packages.

39
00:02:40,000 --> 00:02:44,000
You have the updater where you can check for updates and update the system.

40
00:02:44,000 --> 00:02:48,000
You will have your cubes manager and we'll talk about that in details.

41
00:02:48,000 --> 00:02:49,000
Later on.

42
00:02:49,000 --> 00:02:52,000
You'll have the global settings for the operating system.

43
00:02:52,000 --> 00:02:54,000
Again, we'll talk about that later on.

44
00:02:54,000 --> 00:02:59,000
You have your backups, you have your updates again, screen saver and so on.

45
00:02:59,000 --> 00:03:04,000
So you can spend some time with this trying to familiarize yourself with it or just keep this in mind

46
00:03:04,000 --> 00:03:10,000
that you have the system tools in here in case you want it to modify any settings related to your system.

47
00:03:12,000 --> 00:03:18,000
Other than this, everything else you see in this menu will allow you to launch applications, and all

48
00:03:18,000 --> 00:03:25,000
of these applications are categorized or grouped based on different security domains and different virtual

49
00:03:25,000 --> 00:03:26,000
machines.

50
00:03:26,000 --> 00:03:29,000
And we'll talk about that in more details later on.

51
00:03:30,000 --> 00:03:36,000
Now, moving on to the right on the status bar, you will see that we have four different boxes.

52
00:03:36,000 --> 00:03:38,000
Each box of these is a desktop.

53
00:03:38,000 --> 00:03:42,000
So again, this is similar to a lot of Linux distros and even OS X.

54
00:03:43,000 --> 00:03:49,000
So you can have multiple workspaces where you can launch different applications and manage your windows

55
00:03:49,000 --> 00:03:55,000
and you can easily navigate through them using the status bar in here by simply clicking on the workspace

56
00:03:55,000 --> 00:04:03,000
you want to go to or using the control alt right or left, so control alt and arrow to navigate between

57
00:04:03,000 --> 00:04:03,000
them.

58
00:04:04,000 --> 00:04:09,000
So for example, we already have this window opening here and if I go to the second workspace in here,

59
00:04:09,000 --> 00:04:18,000
I can open my terminal and I can easily navigate between them and here by simply clicking at the workspace

60
00:04:18,000 --> 00:04:22,000
or by doing control, all are left to go back to the first workspace or control.

61
00:04:22,000 --> 00:04:23,000
All right.

62
00:04:23,000 --> 00:04:27,000
To go back to where I have the terminal open at my second workspace.

63
00:04:29,000 --> 00:04:33,000
Moving on to the right again, we have our time and data calendar.

64
00:04:33,000 --> 00:04:34,000
We have the audio settings.

65
00:04:34,000 --> 00:04:37,000
Beside that, we have the network settings.

66
00:04:37,000 --> 00:04:43,000
So if we click on this, you can see first of all, we have the Ethernet network which is saying disconnected.

67
00:04:43,000 --> 00:04:47,000
This is because I don't have a wire connected to the computer.

68
00:04:47,000 --> 00:04:53,000
If you want to connect to an Ethernet network, just plug the Ethernet cable into your computer and

69
00:04:53,000 --> 00:04:56,000
you should be able to see the network in here.

70
00:04:56,000 --> 00:05:00,000
And all we have to do is literally click on the network and connect to connect to it.

71
00:05:01,000 --> 00:05:07,000
Alternatively, if you want to connect over wi fi again for me, you can see it's saying disconnected,

72
00:05:07,000 --> 00:05:10,000
but it's listing all the wi fi networks around me.

73
00:05:11,000 --> 00:05:17,000
Now if you have a wireless card in your computer but you're not seeing any networks, that means that

74
00:05:17,000 --> 00:05:20,000
you need to install the drivers for your card.

75
00:05:20,000 --> 00:05:23,000
And this really depends on the chipset used in the card.

76
00:05:23,000 --> 00:05:29,000
So you'll have to go and Google and research the chipset used and see if it's compatible with cubes.

77
00:05:29,000 --> 00:05:32,000
If it is, you'll have to see how to install the drivers.

78
00:05:32,000 --> 00:05:34,000
In my case I was lucky.

79
00:05:34,000 --> 00:05:39,000
Cube's is able to detect my wi fi card automatically without having to install anything.

80
00:05:39,000 --> 00:05:46,000
So all I have to do is literally click on the network that I want to connect to put the wi fi password.

81
00:05:49,000 --> 00:05:49,000
And perfect.

82
00:05:49,000 --> 00:05:54,000
As you can see, the icon in here changed to an icon that is showing me the signal strength.

83
00:05:54,000 --> 00:05:58,000
And it's also saying the name of the network that I connected to.

84
00:05:58,000 --> 00:06:04,000
And if I click on it, we can see that we are connected to this network and we can click here to disconnect.

85
00:06:04,000 --> 00:06:10,000
So right now, I should have Internet connection on this computer, but I'm not going to open any websites.

86
00:06:10,000 --> 00:06:12,000
We'll talk about that later on.

87
00:06:12,000 --> 00:06:14,000
So we're just going to move on.

88
00:06:14,000 --> 00:06:21,000
Just talking about the basics of cubes and the next icon that we have in here is the clipboard icon.

89
00:06:21,000 --> 00:06:27,000
And this is basically where you'll see whatever you have copied because copy and pasting in this operating

90
00:06:27,000 --> 00:06:33,000
system is slightly different than what you're used to in other operating systems.

91
00:06:33,000 --> 00:06:35,000
Again, to improve the security of the system.

92
00:06:36,000 --> 00:06:38,000
Next we have the device manager.

93
00:06:38,000 --> 00:06:43,000
So in here you have all of the devices connected to this computer right now.

94
00:06:43,000 --> 00:06:49,000
And using this menu you can select where do you want to connect each of these devices?

95
00:06:49,000 --> 00:06:57,000
So as we mentioned, CUBES is designed to improve the security by separating and isolating the different

96
00:06:57,000 --> 00:06:59,000
components of the system.

97
00:06:59,000 --> 00:07:06,000
Therefore, when you connect a USB device or any type of a device, you'll have to explicitly say which

98
00:07:06,000 --> 00:07:08,000
domain you want to connect this device to.

99
00:07:08,000 --> 00:07:14,000
Now, I know this sounds a little bit vague right now, but we'll use it in the future and you'll see

100
00:07:14,000 --> 00:07:20,000
how you can connect different devices to specific security domains and you'll understand how this actually

101
00:07:20,000 --> 00:07:22,000
improves our security.

102
00:07:24,000 --> 00:07:30,000
Next we have the storage manager and you can see the storage devices connected to this computer right

103
00:07:30,000 --> 00:07:30,000
now.

104
00:07:30,000 --> 00:07:34,000
We can also see the disk usage of our system.

105
00:07:34,000 --> 00:07:40,000
Next, we have the cubes manager, which is something that we will spend a lot of time talking about

106
00:07:40,000 --> 00:07:42,000
again later on.

107
00:07:42,000 --> 00:07:50,000
Basically what it does is it shows you the amount of resources each cube or each virtual machine is

108
00:07:50,000 --> 00:07:52,000
using at the moment.

109
00:07:52,000 --> 00:07:57,000
And by hovering over any of these virtual machines will be able to enter its settings.

110
00:07:57,000 --> 00:08:03,000
We'll be able to pause it, shut it down, or run a terminal inside the virtual machine.

111
00:08:03,000 --> 00:08:10,000
If you just go down to the last option in here, open cubes manager, you'll get the cube virtual machine

112
00:08:10,000 --> 00:08:17,000
manager, which allows us to modify various settings of all the installed virtual machines and see their

113
00:08:17,000 --> 00:08:19,000
status, update them and all of that.

114
00:08:19,000 --> 00:08:25,000
And like I said, we will spend a full lecture talking about this, so don't worry about it for now.

115
00:08:25,000 --> 00:08:29,000
Just wanted to show you what it is and how to enter the cube manager.

116
00:08:31,000 --> 00:08:34,000
Finally, we have the update icon in here.

117
00:08:34,000 --> 00:08:37,000
You'll only see this if there are updates available.

118
00:08:37,000 --> 00:08:41,000
Again, you can click on it and launch the updater to update your installation.

119
00:08:41,000 --> 00:08:47,000
We have the power settings beside it and finally we have our user, which is in my case, John.

120
00:08:47,000 --> 00:08:53,000
Clicking on this will allow you to lock the screen, suspend, shut down or log out.

121
00:08:53,000 --> 00:08:59,000
So as you can see, very simple and intuitive interface, you're probably able to figure out most of

122
00:08:59,000 --> 00:09:04,000
the things that I was speaking about earlier by yourself, but I just wanted to make sure that I cover

123
00:09:04,000 --> 00:09:09,000
everything in here before we dive deeper into this operating system.

124
00:09:09,000 --> 00:09:15,000
And I also wanted to cover how all of these are virtual machines in here so that you get an idea of

125
00:09:15,000 --> 00:09:17,000
what's coming in the next lectures.

126
00:09:18,000 --> 00:09:23,000
Now I'm going to go back to the window that I said, you'll see as soon as you log into the computer.

127
00:09:23,000 --> 00:09:27,000
So like I said, this windows is related to the Unix gateway.

128
00:09:27,000 --> 00:09:32,000
This is the gateway that will force all traffic to go through the Tor network.

129
00:09:32,000 --> 00:09:35,000
So this is something that we actually do want to configure.

130
00:09:36,000 --> 00:09:41,000
And you can see the options in here are very similar to the options that we see when we first launch

131
00:09:41,000 --> 00:09:42,000
the Tor browser.

132
00:09:42,000 --> 00:09:47,000
So we can leave it at connect to just connect simply to the Tor network.

133
00:09:47,000 --> 00:09:53,000
We can click configure if you want to use a bridge or a pluggable transport.

134
00:09:53,000 --> 00:09:58,000
Now, if you don't remember what bridges our pluggable transports are, please go back and revise the

135
00:09:58,000 --> 00:10:01,000
lectures where I cover them because I cover them in details.

136
00:10:01,000 --> 00:10:07,000
And I covered multiple ways on how to get bridges and and pluggable transports and why you might want

137
00:10:07,000 --> 00:10:08,000
to use them.

138
00:10:08,000 --> 00:10:13,000
Therefore, I'm just going to keep this at connect at the basic setting and I'm going to click on next.

139
00:10:14,000 --> 00:10:19,000
And this is just showing us a summary that we're going to be connecting to the Tor network.

140
00:10:19,000 --> 00:10:23,000
The bridges are disabled and we're not using any proxies, so that's fine.

141
00:10:23,000 --> 00:10:24,000
We're going to click on next.

142
00:10:26,000 --> 00:10:27,000
And perfect.

143
00:10:27,000 --> 00:10:31,000
As you can see right now, it's telling us that we are connected to the terror network.

144
00:10:31,000 --> 00:10:35,000
Now, keep in mind, please don't go and start browsing straight away.

145
00:10:35,000 --> 00:10:41,000
Not all web browsers in this operating system will forward traffic through the Tor network.

146
00:10:41,000 --> 00:10:44,000
So don't just go and access dark web websites right now.

147
00:10:44,000 --> 00:10:46,000
Wait for the next lectures.

148
00:10:46,000 --> 00:10:53,000
And I will explain to you the different web browsers and the different gateways inside this cool operating

149
00:10:53,000 --> 00:10:54,000
system.
