‫-: Hi, starting from this lecture
‫we are gonna take a look at the Kali Linux and in fact
‫we're gonna have a look at the Linux generally.
‫We're gonna see how it looks, how to use it,
‫how to use the command line,
‫how to change the settings, so on and so forth.
‫This will be introduction to Linux.
‫So make sure your Kali Linux is working
‫and you managed to solve all the problems
‫in the previous section.
‫Okay, so we are going to start the Kali Linux.
‫It doesn't matter if you're using Virtual Box
‫it doesn't matter if you're using VMware, or UTM.
‫Just start the Kali Linux.
‫And in fact, it doesn't even matter
‫if what kind of version of Kali Linux you are using, okay?
‫Make sure you have a working copy and as I said before
‫you may witness different kind of backgrounds
‫on the desktop for Kali Linux during the course,
‫during you watched the lectures of this course.
‫And it doesn't even matter
‫whether you downloaded my own version of VA
‫for specifically created for this course
‫or even if you downloaded kali.org ISO or OVA.
‫It doesn't matter.
‫Again, the thing is we have to learn how to use Linux.
‫We don't learn how to use specific kind of Kali Linux
‫or specific version of Kali Linux.
‫We need to learn about the logic,
‫we need to learn about foldering mechanisms of Kali Linux
‫and something like that, okay?
‫And that's what we intend to do during this section.
‫So I'm going to start my Kali Linux, okay?
‫And I'm going to use the one that I have downloaded
‫from the kali.org
‫because it's a little bit trickier
‫to use that kind of version rather than the specific version
‫that has been created for this course, okay?
‫So let me log in with the Kali in Kali.
‫And remember you need to log in with Root and T-O-O-R
‫if you're using the specific version, okay?
‫But if not, just log in with the Kali in Kali
‫and then later on after this section,
‫I believe you would be able to understand everything
‫that we are doing inside of the Linux
‫for the rest of the course.
‫And again, if you come across in a situation
‫where you can't make it work,
‫just go back and download the one
‫that has been created for this course.
‫Anyway, as you can see right now, I'm seeing the Kali Linux.
‫If you are not seeing it full screen like this,
‫just make it full screen.
‫But if it does not adjust, don't worry about it.
‫I'm gonna show you how to change the resolution
‫of this Kali Linux.
‫Anyway, long story short, we have our operating system.
‫As you can see, this is the desktop.
‫There are some icons over here just like Windows
‫or just like Mac.
‫You can put anything you want over here
‫and you will see some kind of icons over there.
‫They're just shortcuts.
‫We can reach them through the main menu, okay?
‫Don't worry about the shortcuts over here.
‫So let me walk you over
‫to everything that you see on the screen.
‫If you click on the left hand side over this icon
‫you will see the tools.
‫So these are tools that come with Kali Linux, okay?
‫The ordering of the tools and stuff can change
‫but there should be some kind of settings icon, okay?
‫If you click on that settings icon
‫you can change the settings of the Kali Linux.
‫You can change the appearance, you can change the desktop,
‫you can change whatever you want.
‫It's all up to you.
‫For example, if I go into the appearance, as you can see
‫I'm using, it seems that I'm using Kali Dark right now.
‫I can go to something else, I can change the fonts,
‫I can change the icons, I can do whatever I want.
‫I'm not even going to change that, okay?
‫I'm not even going to bother with that.
‫But the thing that I want to show you over here
‫is that you can change everything.
‫You can change the desktop settings,
‫you can change the file manager notification settings
‫as well.
‫And over here there is something called display
‫which is important.
‫If you are not seeing this full screen,
‫you can come over here to display
‫and change your resolution.
‫Right now I'm using this with 1920, 1080, okay?
‫You can just change it
‫in a way that you want and if you apply it
‫then your screen resolution will be adjusted.
‫Just change it from here and you will have a bigger screen.
‫Great, now that's the only option, that's the only setting
‫that I wanted to show you, okay?
‫Because if you are not using Kali Linux with a proper screen
‫then you will have a hard time.
‫So if you adjusted that, then it's okay.
‫You don't even have to change any settings.
‫Now maybe you may want to change the keyboard, okay?
‫As you can see there is a keyboard option here as well.
‫For example, I'm using a Turkish keyboard right now
‫and it'll cause me some problems,
‫but it's easier to do this
‫with the command line with the terminal.
‫I'm going to show you what I mean
‫later on during this lecture,
‫but I just wanted to give you a heads up.
‫Anyway, so I don't wanna change the keyboard right now.
‫I'm just gonna do it with the terminal.
‫But if you want, you can just go over there
‫and add some languages.
‫So over here you have the Firefox as the browser.
‫This is one thing you should check
‫because if you don't have an internet connection
‫then it will be kind of problem for you.
‫Right now, you can browse to any website, like google.com
‫or kali.org just to test if you have any kind of connection.
‫Now I'm gonna go into the google.com
‫and let's see if we see the thing.
‫Yeah, here you go.
‫By the way, my keyboard is not very working right now.
‫As you can see, if I click on some of the characters,
‫it displays another character over here.
‫That's because we haven't adjusted it
‫according to our local machine.
‫I'm gonna show you have to do that.
‫But make sure you have an internet connection,
‫if you don't, go back to the virtual box
‫and make sure you choose the NAT network
‫from the network section, okay?
‫If you have the internet connection
‫you shouldn't change anything.
‫If you selected the NAT network
‫and still don't have the internet connection
‫maybe you can go to preferences
‫or settings and create another NAT network
‫like we have done before from here.
‫And make sure you choose the name NATNetwork
‫from the Kali Linux and try one more time.
‫Sometimes antivirus solutions
‫block this kind of connection as well.
‫Maybe you can try to disable your antivirus solution
‫and try with that.
‫But you gotta have internet connection,
‫not only to connect internet from Kali Linux
‫but also to download tools that we will be using
‫throughout the course, okay?
‫So over here, which we have the terminal emulator
‫which is the most important thing
‫and you can reach it from this icon as well.
‫So you will see terminal emulator and root terminal emulator
‫if you're using the latest version.
‫So I will talk about the differences between them.
‫And if you are using the OVA
‫that has been created for this course,
‫all the emulators will be root emulators, okay?
‫The root terminals.
‫So if you click on the terminal
‫it will be open as root and root or root and Kali.
‫But over here we are seeing that Kali and Kali,
‫and if you have installed with the ISO,
‫let me make this a little bit smaller,
‫you may see your own username
‫and that is okay, we're going to talk about this, okay?
‫You can make this smaller, you can make this full size
‫and everything.
‫So this is a terminal, and once we write a command
‫and hit enter, the command will be executed for us
‫by the Kali Linux.
‫We will be using this a lot throughout the course.
‫And in fact, we are not going to use GUI,
‫the graphical user interface very much.
‫We are going to do everything with the terminal, okay?
‫So you better get used to it and I'll just make sure
‫that I will walk you through every step Of it.
‫No worries.
‫So I'm here and if I write any comment
‫that Kali Linux accepts, it will be executed for me.
‫So what do I mean by that?
‫By writing comments?
‫For example, changing the keyboard,
‫changing the, seeing the IP addresses,
‫creating files, deleting folders, stuff like that, okay?
‫Anything that comes to your mind.
‫But first of all, I want to start by changing my keyboard.
‫So the command to do that is this, setskbmaptr.
‫Don't do that right now, okay?
‫If you are keyboard is working
‫as you would expect, then it's okay.
‫Don't do that.
‫Since I'm using a Turkish keyboard right now
‫I have to write that comment
‫and make sure Kali adjusts itself to my keyboard.
‫If you're using any kind of keyboard
‫that does not work well right now,
‫just write this comment and put your own country code.
‫For example, for UK you may put UK, okay?
‫So for Turkish characters I just put TR.
‫Right now every Turkish character works for me
‫and I have to do that every time I open the Kali Linux,
‫okay?
‫So if your keyboard is already working,
‫don't worry about it.
‫But if not, just make sure you write this comment
‫every time you open the Kali Linux.
‫Great, now I'm ready to write some comment
‫and execute those commands.
‫But that is not why we are here for in this lecture.
‫We are just seeing the overview of the Kali Linux.
‫We are going to spend so much time doing that.
‫Following with the next lecture so I just closed this down.
‫Here you see some icons,
‫there is a wired connection over here
‫which is the NAT network, obviously.
‫We are connected with the NAT network.
‫It thinks it's wirely connect,
‫connect with wire to the virtual box.
‫We have the other things like volume, we have the clock
‫and we have some kind of battery status
‫and something like that.
‫So these are just for notifications
‫and very general settings, okay?
‫You don't need to do anything over here.
‫Of course you can see the calendar,
‫you can log out, shut down Kali from here,
‫from this icons, lock the screen
‫and log in one more time.
‫You don't have to do that.
‫In my opinion, all you gotta do
‫is just find where to open the terminal, okay?
‫Also, if you come over here, you can see the favorites,
‫you can see other stuff, other tools.
‫If you double click on the home or any kind of file system
‫it'll take you through the file manager
‫you will see the documents,
‫you will see the downloads, music, pictures.
‫So for example, apparently I have some files over here.
‫I'm just gonna delete them.
‫As you can see, we can use Kali
‫as if it's a a regular operating system
‫like Windows and Mac.
‫We can create files
‫we can store folders, something like that.
‫And over here
‫in the file system we see the Linux folders,
‫which we will be covering in the upcoming lectures.
‫These are general Linux folders
‫not specific to Kali Linux
‫but also for the other distributions as well.
‫So we will learn what kind of things
‫that we can store inside of those folders, okay?
‫So that's it.
‫That's the file system.
‫You can go into the music, you can go into the desktop,
‫you can go into the downloads
‫and just store anything you want.
‫On the computer of,
‫obviously you will see the CD that we have created,
‫the virtual box hard disc for this kind of purpose.
‫But we cannot go into that and change anything from here.
‫Obviously it wouldn't make sense.
‫Great, now there are some workspaces over here.
‫For example, if you open any window like this,
‫if you go to another workspace,
‫assume that you have a lot of things going on,
‫you go into the second workspace which is clean,
‫and when you are done,
‫you can go back to the first workspace
‫and you see the things,
‫the windows that you left open before.
‫So these are just workspaces.
‫And again, all you gotta do is just figure out
‫how to open the terminal and maybe the file system as well.
‫So long story short,
‫we have to understand how to work with terminal.
‫So that's exactly what we are going to do
‫following the next lecture.
