1 1 00:00:01,090 --> 00:00:03,850 Okay, now that we have Kali Linux installed, 2 2 00:00:03,850 --> 00:00:07,760 I want to give you a basic overview of this Operating System 3 3 00:00:07,760 --> 00:00:10,550 in this lecture, so that you're comfortable with it. 4 4 00:00:10,550 --> 00:00:13,240 And we're gonna be using it throughout the whole course, 5 5 00:00:13,240 --> 00:00:15,940 so, everything is going to become easier for you 6 6 00:00:15,940 --> 00:00:17,423 as we go through the course. 7 7 00:00:18,630 --> 00:00:20,380 Now, the first thing that I wanna talk about 8 8 00:00:20,380 --> 00:00:22,610 is the status bar in here. 9 9 00:00:22,610 --> 00:00:26,250 So you can see we have an Applications Menu in here, 10 10 00:00:26,250 --> 00:00:28,320 and inside it, you can see 11 11 00:00:28,320 --> 00:00:31,520 all the applications are categorized. 12 12 00:00:31,520 --> 00:00:34,310 So we have information gathering applications, 13 13 00:00:34,310 --> 00:00:38,020 vulnerability analysis, web application analysis, 14 14 00:00:38,020 --> 00:00:41,430 reverse engineering, and so on. 15 15 00:00:41,430 --> 00:00:43,960 So you can go on each one of these entries 16 16 00:00:43,960 --> 00:00:46,513 and just select any program that you want to run. 17 17 00:00:47,560 --> 00:00:50,430 And the next menu that we have is the Places, 18 18 00:00:50,430 --> 00:00:54,510 which shows you the most common places in the file system. 19 19 00:00:54,510 --> 00:00:57,380 So, we have home we have the desktop, we have the documents, 20 20 00:00:57,380 --> 00:00:58,743 downloads, and so on. 21 21 00:00:59,720 --> 00:01:01,680 So you can access the places from here 22 22 00:01:01,680 --> 00:01:03,520 and then you click on home, 23 23 00:01:03,520 --> 00:01:07,120 or you can just click on the files icon in here on the left. 24 24 00:01:07,120 --> 00:01:10,310 And both of these will bring you to the home directory, 25 25 00:01:10,310 --> 00:01:13,120 which is actually the root directory. 26 26 00:01:13,120 --> 00:01:17,410 So, it says home in here, but the actual location of this, 27 27 00:01:17,410 --> 00:01:22,023 if I do Control + L, you'll see it is /route. 28 28 00:01:23,080 --> 00:01:25,740 So, inside this you can see we have our Downloads, 29 29 00:01:25,740 --> 00:01:28,720 Music, Pictures, similar to the way that you'd have it 30 30 00:01:28,720 --> 00:01:30,473 in Windows and OS X. 31 31 00:01:31,550 --> 00:01:35,070 We also have the time in here, and in here on the right, 32 32 00:01:35,070 --> 00:01:36,870 we have more controls. 33 33 00:01:36,870 --> 00:01:40,750 So, the first thing that we have in here is the workspaces. 34 34 00:01:40,750 --> 00:01:44,323 So, Linux comes with multiple workspaces by default. 35 35 00:01:45,170 --> 00:01:47,150 Basically, what these allows us to do, 36 36 00:01:47,150 --> 00:01:49,940 is we can have this desktop in here for example, 37 37 00:01:49,940 --> 00:01:53,360 we can open the places and we can, for example, 38 38 00:01:53,360 --> 00:01:55,973 navigate to Downloads and do some work in here. 39 39 00:01:56,860 --> 00:02:01,860 But if we go here to work places and go to the second one, 40 40 00:02:02,530 --> 00:02:04,530 you can see that I have an empty desktop 41 41 00:02:04,530 --> 00:02:06,280 that I can do whatever I want. 42 42 00:02:06,280 --> 00:02:08,853 And for example, I can launch Firefox in here. 43 43 00:02:10,610 --> 00:02:14,160 And then again, if I want to go back to the first workspace, 44 44 00:02:14,160 --> 00:02:17,810 all I have to do is click on here, click on number one, 45 45 00:02:17,810 --> 00:02:19,133 and I'm back in here. 46 46 00:02:20,090 --> 00:02:23,020 And because I've already used up two spaces, 47 47 00:02:23,020 --> 00:02:26,430 the system is already creating a third empty space, 48 48 00:02:26,430 --> 00:02:28,770 so I can click on that and as you can see, 49 49 00:02:28,770 --> 00:02:31,633 I'm in the third space where I can do more stuff. 50 50 00:02:32,870 --> 00:02:35,240 Now, you can also navigate between the spaces 51 51 00:02:35,240 --> 00:02:40,240 by pressing Control + Alt up or down to go up and down 52 52 00:02:40,720 --> 00:02:41,713 in the spaces. 53 53 00:02:42,630 --> 00:02:46,450 The next part of the status bar is this last part in here. 54 54 00:02:46,450 --> 00:02:48,900 And if you click on it, basically the first thing 55 55 00:02:48,900 --> 00:02:51,830 it'll allow you to do is control the sound. 56 56 00:02:51,830 --> 00:02:54,450 Next, you'll see your connections. 57 57 00:02:54,450 --> 00:02:57,330 So, as you can see right now, as I showed you before, 58 58 00:02:57,330 --> 00:02:59,270 this is showing up as if we're connected 59 59 00:02:59,270 --> 00:03:02,930 to a wired network because I configured this network 60 60 00:03:02,930 --> 00:03:04,543 to use a NAT network. 61 61 00:03:05,520 --> 00:03:08,930 If you have a wireless adapter connected to this computer, 62 62 00:03:08,930 --> 00:03:11,150 you should be able to see it here. 63 63 00:03:11,150 --> 00:03:13,770 If you don't see it, then follow the link 64 64 00:03:13,770 --> 00:03:15,720 in the resources of this lecture 65 65 00:03:15,720 --> 00:03:19,010 to see how to properly connect your wireless adapter 66 66 00:03:19,010 --> 00:03:22,483 or any USB device to a virtual machine. 67 67 00:03:23,380 --> 00:03:28,230 Now I should note you can only use external USB adapters 68 68 00:03:28,230 --> 00:03:31,760 in order to access WiFi networks from Kali. 69 69 00:03:31,760 --> 00:03:34,443 You cannot use the built in WiFi card. 70 70 00:03:35,350 --> 00:03:38,040 But Kali should have Internet connection anyway 71 71 00:03:38,040 --> 00:03:40,770 because it is configured to use a NAT network 72 72 00:03:40,770 --> 00:03:42,060 and as you can see in here 73 73 00:03:42,060 --> 00:03:45,090 it's telling me my wired is connected. 74 74 00:03:45,090 --> 00:03:48,773 So, if I actually go down to Firefox, I'll close this. 75 75 00:03:50,660 --> 00:03:53,513 And if I just go to google.com, 76 76 00:03:54,390 --> 00:03:56,933 you can see it is connected to the Internet. 77 77 00:03:58,000 --> 00:04:03,000 So, let's go back to where we were, and if we click here, 78 78 00:04:04,140 --> 00:04:08,670 we also have the battery settings, the user settings, 79 79 00:04:08,670 --> 00:04:11,150 you have this button to turn off the machine, 80 80 00:04:11,150 --> 00:04:13,090 this is to lock the machine, 81 81 00:04:13,090 --> 00:04:15,210 and this will show the preferences 82 82 00:04:15,210 --> 00:04:17,810 where you can modify the preferences of the machine. 83 83 00:04:17,810 --> 00:04:21,480 So, you have Bluetooth, WiFi, change the background, 84 84 00:04:21,480 --> 00:04:24,670 change the languages, and so on. 85 85 00:04:24,670 --> 00:04:27,430 So you can spend some time getting familiar with this, 86 86 00:04:27,430 --> 00:04:30,060 it's very easy and very intuitive. 87 87 00:04:30,060 --> 00:04:33,170 Same goes to the file manager in here, very intuitive. 88 88 00:04:33,170 --> 00:04:36,180 Double click to go in, you can right click on archive 89 89 00:04:36,180 --> 00:04:38,700 and extract here to uncompressed it. 90 90 00:04:38,700 --> 00:04:41,820 You can navigate throughout these files by clicking them 91 91 00:04:41,820 --> 00:04:43,420 and then you have the trash here, 92 92 00:04:43,420 --> 00:04:45,593 which contains the deleted files. 93 93 00:04:47,350 --> 00:04:49,150 Now, we also have the doc in here 94 94 00:04:49,150 --> 00:04:52,270 which contains the favorite applications. 95 95 00:04:52,270 --> 00:04:56,060 And you can also access all the other applications 96 96 00:04:56,060 --> 00:05:00,420 by clicking on this icon right here, the show applications. 97 97 00:05:00,420 --> 00:05:02,110 And this will show you a menu 98 98 00:05:02,110 --> 00:05:04,570 with the most frequent applications. 99 99 00:05:04,570 --> 00:05:06,560 And then if you click on all, 100 100 00:05:06,560 --> 00:05:09,403 it will show you all the available applications.
