Ok, now that we have Kali Linux installed,
I want to give you a basic overview of this operating system in this lecture, so that you're comfortable with it
and we're going to be using it throughout the whole course so everything is going to become easier for you
as we go through the course.
Now the first thing that I want to talk about is the status bar in here,
so, you can see we have an applications menu in here
and inside it you can see all the applications are categorized.
So we have information gathering applications, vulnerability analysis, web application analysis,
reverse engineering and so on.
So you can go on each one of these entries and just select any program that you want to run.
And the next menu that we have is the places which shows you
the most common places in the file system.
So we have home, we have the desktop, we have the documents, downloads and so on.
So you can access the places from here and then you click on 'home'
or you can just click on the files icon in here on the left
and both of these will bring you to the home directory, which is actually the root directory.
So it says home in here but the actual location of this, if I do 'Ctrl + L' , you'll see it is '/root'.
So inside this you can see we have our downloads, music, pictures,
similar to the way that you'd have it in Windows and OS X.
We also have the time in here and in here on the right we have more controls,
So the first thing that we have in here is the workspaces.
So Linux comes with multiple workspaces by default.
Basically what this allow us to do is we can have this desktop in here
for example we can open the places and we can, for example, navigate to downloads
and do some work in here.
But if we go here to workplaces and go to the second one,
you can see that I have an empty desktop that I can do whatever I want
and for example I can launch Firefox in here.
And then again if I want to go back to the first workspace, all I have to do is click on here,
click on number one and I'm back in here.
And because I've already used up two spaces, the system is already creating a third empty space,
so I can click on that and as you can see I'm in the third space, where I can do more stuff.
Now you can also navigate between the spaces by pressing 'Ctrl + Alt + up or down',
to go up and down in the spaces.
The next part of the status bar is this last part in here and if you click on it
basically the first thing it'll allow you to do is control the sound.
Next you'll see your connections, so as you can see right now and as I showed you before,
this is showing up as if we're connected to a wired network
because I configured this network to use a nat network.
If you have a wireless adapter connected to this computer, you should be able to see it here.
If you don't see it, then follow the link in the resources of this lecture
to see how to properly connect your wireless adapter or any USB device to a virtual machine.
Now I should note, you can only use external USB adapters in order to access Wi-Fi networks from Kali.
You can not use the built-in Wi-Fi card.
But Kali should have internet connection anyway because it is configured to use an ad network
and as you can see in here it's telling me my wired is connected.
So if I actually go down to Firefox, I'll close this,
and if I just go to 'google.com'
you can see it is connected to the Internet.
So, let's go back to where we were
and if we click here, we also have the battery settings, the user settings,
you have this button to turn off the machine, this is to lock the machine
and this will show the preferences where you can modify the preferences of the machine.
So you have Bluetooth, Wi-Fi, change the background, change the languages and so on.
So you can spend some time getting familiar with this.
It's very easy and very intuitive.
Same goes to the file manager in here, very intuitive, double-click to go in.
You can right click an archive and extract here to uncompress it.
You can navigate throughout these files by clicking them and then you have the trash here,
which contains the deleted files.
Now we also have the dock in here which contains the favorite applications
and you can also access all the other applications by clicking on this icon right here.
This shows applications and this will show you a menu with the most frequent applications
and then if you click on all, it will show you all the available applications.
