WEBVTT 00:01.060 --> 00:01.510 Okay. 00:01.510 --> 00:08.140 So now that we have cubes installed and we booted into it and we logged in and this lecture, I want 00:08.140 --> 00:15.130 to give you a very basic overview of the operating system, and then we'll get to use it more and more 00:15.130 --> 00:16.720 as we go through the course. 00:17.650 --> 00:24.970 So as soon as you log in, you will probably see this window right here, which is a configuration window 00:24.970 --> 00:26.780 for the Unix gateway. 00:26.800 --> 00:34.030 This is the gateway that will direct all the data that we send to the Internet and force it to go through 00:34.030 --> 00:35.110 the Tor network. 00:35.680 --> 00:40.810 Now, before configuring this, I want to give you an overview of the operating system. 00:40.810 --> 00:41.670 Like I said. 00:41.680 --> 00:47.350 So I'm going to keep this to the side because I want to connect to the Internet first before we configure 00:47.350 --> 00:47.890 this. 00:48.690 --> 00:49.740 The first impression. 00:49.740 --> 00:54.880 You'll probably notice that this looks very similar to a lot of Linux operating systems. 00:54.900 --> 01:01.380 You have a status bar in here that shows the running applications and on the left here you have a menu 01:01.380 --> 01:06.060 which allows you to run various applications in this operating system. 01:06.540 --> 01:12.270 You'll notice we can run a terminal in here, which is very similar to Linux terminals, like I said, 01:12.270 --> 01:17.520 and runs a lot of Linux commands plus some cube specific commands. 01:18.770 --> 01:25.220 Other than this, you will also notice that we have System Tools menu which allows you to access different 01:25.220 --> 01:28.490 applications related to the operating system. 01:28.490 --> 01:32.510 The one that you'll be using the most is the Settings manager. 01:32.660 --> 01:35.390 Again, this is very similar to the settings application. 01:35.390 --> 01:41.060 You get on a lot of Linux distros and it allows you to change the various settings of the operating 01:41.060 --> 01:41.720 system. 01:42.200 --> 01:48.510 You can change the appearance, the desktop, the background, the windows, the mouse and keyboard, 01:48.510 --> 01:50.150 the languages and so on. 01:50.570 --> 01:55.520 I've actually used this to modify the font size and the icons and even the theme here on top. 01:55.520 --> 02:01.370 So you'll notice the theme that I have right now is slightly different than what you see on your desktop 02:01.370 --> 02:02.960 if you just install cubes. 02:02.990 --> 02:08.630 The reason why I did this is just to make it a little bit more readable and easy for you to see what 02:08.630 --> 02:09.220 I'm doing. 02:09.230 --> 02:15.710 If you're watching this from a small screen or from a phone, so very simple settings, you can click 02:15.710 --> 02:21.290 on whatever center you want to modify and then you can modify the different settings just like any other 02:21.290 --> 02:22.310 operating system. 02:22.310 --> 02:26.450 So it's very, very intuitive and there is no point of wasting time on this. 02:27.260 --> 02:32.720 Again, in the system tools other than the settings manager, you will find various settings and various 02:32.720 --> 02:36.170 applications that you can use to configure your system. 02:36.170 --> 02:40.760 So you have the package manager where you can install different programs in different packages. 02:40.760 --> 02:44.570 You have the updater where you can check for updates and update the system. 02:44.900 --> 02:48.470 You will have your cubes manager and we'll talk about that in details. 02:48.470 --> 02:49.360 Later on. 02:49.370 --> 02:52.520 You'll have the global settings for the operating system. 02:52.520 --> 02:54.590 Again, we'll talk about that later on. 02:54.590 --> 02:59.420 You have your backups, you have your updates again, screen saver and so on. 02:59.420 --> 03:04.760 So you can spend some time with this trying to familiarize yourself with it or just keep this in mind 03:04.760 --> 03:10.820 that you have the system tools in here in case you want it to modify any settings related to your system. 03:12.230 --> 03:18.440 Other than this, everything else you see in this menu will allow you to launch applications, and all 03:18.440 --> 03:25.460 of these applications are categorized or grouped based on different security domains and different virtual 03:25.460 --> 03:26.300 machines. 03:26.300 --> 03:29.390 And we'll talk about that in more details later on. 03:30.230 --> 03:36.020 Now, moving on to the right on the status bar, you will see that we have four different boxes. 03:36.050 --> 03:38.810 Each box of these is a desktop. 03:38.810 --> 03:42.980 So again, this is similar to a lot of Linux distros and even OS X. 03:43.310 --> 03:49.100 So you can have multiple workspaces where you can launch different applications and manage your windows 03:49.100 --> 03:55.100 and you can easily navigate through them using the status bar in here by simply clicking on the workspace 03:55.100 --> 04:03.140 you want to go to or using the control alt right or left, so control alt and arrow to navigate between 04:03.140 --> 04:03.650 them. 04:04.190 --> 04:09.890 So for example, we already have this window opening here and if I go to the second workspace in here, 04:09.890 --> 04:18.110 I can open my terminal and I can easily navigate between them and here by simply clicking at the workspace 04:18.110 --> 04:22.850 or by doing control, all are left to go back to the first workspace or control. 04:22.850 --> 04:23.450 All right. 04:23.450 --> 04:27.320 To go back to where I have the terminal open at my second workspace. 04:29.400 --> 04:33.060 Moving on to the right again, we have our time and data calendar. 04:33.060 --> 04:34.890 We have the audio settings. 04:34.890 --> 04:37.170 Beside that, we have the network settings. 04:37.170 --> 04:43.530 So if we click on this, you can see first of all, we have the Ethernet network which is saying disconnected. 04:43.530 --> 04:47.640 This is because I don't have a wire connected to the computer. 04:47.640 --> 04:53.610 If you want to connect to an Ethernet network, just plug the Ethernet cable into your computer and 04:53.610 --> 04:56.040 you should be able to see the network in here. 04:56.040 --> 05:00.930 And all we have to do is literally click on the network and connect to connect to it. 05:01.770 --> 05:07.260 Alternatively, if you want to connect over wi fi again for me, you can see it's saying disconnected, 05:07.260 --> 05:10.650 but it's listing all the wi fi networks around me. 05:11.340 --> 05:17.310 Now if you have a wireless card in your computer but you're not seeing any networks, that means that 05:17.310 --> 05:20.160 you need to install the drivers for your card. 05:20.160 --> 05:23.400 And this really depends on the chipset used in the card. 05:23.400 --> 05:29.250 So you'll have to go and Google and research the chipset used and see if it's compatible with cubes. 05:29.250 --> 05:32.400 If it is, you'll have to see how to install the drivers. 05:32.400 --> 05:34.230 In my case I was lucky. 05:34.260 --> 05:39.540 Cube's is able to detect my wi fi card automatically without having to install anything. 05:39.540 --> 05:46.050 So all I have to do is literally click on the network that I want to connect to put the wi fi password. 05:49.100 --> 05:49.790 And perfect. 05:49.790 --> 05:54.320 As you can see, the icon in here changed to an icon that is showing me the signal strength. 05:54.320 --> 05:58.000 And it's also saying the name of the network that I connected to. 05:58.010 --> 06:04.280 And if I click on it, we can see that we are connected to this network and we can click here to disconnect. 06:04.490 --> 06:10.390 So right now, I should have Internet connection on this computer, but I'm not going to open any websites. 06:10.400 --> 06:12.320 We'll talk about that later on. 06:12.980 --> 06:14.330 So we're just going to move on. 06:14.330 --> 06:21.620 Just talking about the basics of cubes and the next icon that we have in here is the clipboard icon. 06:21.620 --> 06:27.830 And this is basically where you'll see whatever you have copied because copy and pasting in this operating 06:27.830 --> 06:33.090 system is slightly different than what you're used to in other operating systems. 06:33.110 --> 06:35.750 Again, to improve the security of the system. 06:36.600 --> 06:38.840 Next we have the device manager. 06:38.850 --> 06:43.950 So in here you have all of the devices connected to this computer right now. 06:43.950 --> 06:49.950 And using this menu you can select where do you want to connect each of these devices? 06:49.950 --> 06:57.330 So as we mentioned, CUBES is designed to improve the security by separating and isolating the different 06:57.330 --> 06:59.010 components of the system. 06:59.400 --> 07:06.300 Therefore, when you connect a USB device or any type of a device, you'll have to explicitly say which 07:06.300 --> 07:08.950 domain you want to connect this device to. 07:08.970 --> 07:14.190 Now, I know this sounds a little bit vague right now, but we'll use it in the future and you'll see 07:14.190 --> 07:20.670 how you can connect different devices to specific security domains and you'll understand how this actually 07:20.670 --> 07:22.380 improves our security. 07:24.330 --> 07:30.570 Next we have the storage manager and you can see the storage devices connected to this computer right 07:30.570 --> 07:30.840 now. 07:30.840 --> 07:34.170 We can also see the disk usage of our system. 07:34.710 --> 07:40.860 Next, we have the cubes manager, which is something that we will spend a lot of time talking about 07:40.860 --> 07:42.120 again later on. 07:42.450 --> 07:50.940 Basically what it does is it shows you the amount of resources each cube or each virtual machine is 07:50.940 --> 07:52.430 using at the moment. 07:52.440 --> 07:57.900 And by hovering over any of these virtual machines will be able to enter its settings. 07:57.900 --> 08:03.120 We'll be able to pause it, shut it down, or run a terminal inside the virtual machine. 08:03.780 --> 08:10.980 If you just go down to the last option in here, open cubes manager, you'll get the cube virtual machine 08:10.980 --> 08:17.400 manager, which allows us to modify various settings of all the installed virtual machines and see their 08:17.400 --> 08:19.740 status, update them and all of that. 08:19.740 --> 08:25.330 And like I said, we will spend a full lecture talking about this, so don't worry about it for now. 08:25.350 --> 08:29.670 Just wanted to show you what it is and how to enter the cube manager. 08:31.170 --> 08:34.380 Finally, we have the update icon in here. 08:34.380 --> 08:37.270 You'll only see this if there are updates available. 08:37.290 --> 08:41.630 Again, you can click on it and launch the updater to update your installation. 08:41.640 --> 08:47.580 We have the power settings beside it and finally we have our user, which is in my case, John. 08:47.760 --> 08:53.310 Clicking on this will allow you to lock the screen, suspend, shut down or log out. 08:53.820 --> 08:59.970 So as you can see, very simple and intuitive interface, you're probably able to figure out most of 08:59.970 --> 09:04.980 the things that I was speaking about earlier by yourself, but I just wanted to make sure that I cover 09:04.980 --> 09:09.330 everything in here before we dive deeper into this operating system. 09:09.330 --> 09:15.600 And I also wanted to cover how all of these are virtual machines in here so that you get an idea of 09:15.600 --> 09:17.640 what's coming in the next lectures. 09:18.180 --> 09:23.190 Now I'm going to go back to the window that I said, you'll see as soon as you log into the computer. 09:23.250 --> 09:27.480 So like I said, this windows is related to the Unix gateway. 09:27.510 --> 09:32.630 This is the gateway that will force all traffic to go through the Tor network. 09:32.640 --> 09:35.670 So this is something that we actually do want to configure. 09:36.060 --> 09:41.640 And you can see the options in here are very similar to the options that we see when we first launch 09:41.640 --> 09:42.720 the Tor browser. 09:42.720 --> 09:47.520 So we can leave it at connect to just connect simply to the Tor network. 09:47.520 --> 09:53.010 We can click configure if you want to use a bridge or a pluggable transport. 09:53.040 --> 09:58.380 Now, if you don't remember what bridges our pluggable transports are, please go back and revise the 09:58.380 --> 10:01.230 lectures where I cover them because I cover them in details. 10:01.230 --> 10:07.320 And I covered multiple ways on how to get bridges and and pluggable transports and why you might want 10:07.320 --> 10:08.100 to use them. 10:08.490 --> 10:13.710 Therefore, I'm just going to keep this at connect at the basic setting and I'm going to click on next. 10:14.340 --> 10:19.280 And this is just showing us a summary that we're going to be connecting to the Tor network. 10:19.290 --> 10:23.430 The bridges are disabled and we're not using any proxies, so that's fine. 10:23.430 --> 10:24.930 We're going to click on next. 10:26.380 --> 10:27.070 And perfect. 10:27.070 --> 10:31.060 As you can see right now, it's telling us that we are connected to the terror network. 10:31.090 --> 10:35.350 Now, keep in mind, please don't go and start browsing straight away. 10:35.380 --> 10:41.250 Not all web browsers in this operating system will forward traffic through the Tor network. 10:41.260 --> 10:44.830 So don't just go and access dark web websites right now. 10:44.860 --> 10:46.690 Wait for the next lectures. 10:46.690 --> 10:53.380 And I will explain to you the different web browsers and the different gateways inside this cool operating 10:53.380 --> 10:54.040 system.
