 Welcome back everyone. Today, we're going to be installing virtual box guest additions into CaliLinux. So before we installed CaliLinux into a virtual machine using virtual box and then we upgraded CaliLinux, now we need to install virtual box guest additions. And you know, you can tell whether guest additions are installed because inside our virtual machine here, if we try to stretch or resize the actual virtual machine, the desktop will not resize with the actual virtual machine. So with guest additions, we can do a lot of things with file sharing and also better support for resizing and basically changing the resolution of the system itself. So installing guest additions is kind of a must have if we want to get all of the features out of the virtual machine. So we have CaliLinux open and we go back into the terminal, this black icon here. If I open this up, black icon, I'm logged in currently as root. So if you're logged in as a different user that doesn't have administrative access, you need to either log in as root or use sudo before you type any of these commands. Because I'm logged in as root, I do not need to use sudo. And what we want to do is run sudo apt get update to be able to update the software or the packages that we have in here. So we need to run sudo apt get update. And this will go out and look for all of the packages that are currently available for this system. Okay, so it's already found the packages. So now it has an updated list of all of the software. Then we want to run apt get install virtual box guest. And I believe it was x11. Yep. So apt dash get install virtual box dash guest dash x11. Okay. And then when we install that, then it will download looks like 25 megabyte, 25 megabytes of data. And then it will install the guest additions. And whenever we restart the system, then guest additions will be installed. And we'll see a major difference in the guest system. So I'll let that download and I'll come back to you whenever it's finished. Okay. So now that we're finished installing the guest additions, then we need to reboot. So you can just type reboot shutdown now dash R shut down now dash R. And that will shut down the computer now. And the dash R makes it restart. Okay. So now we've logged in and you can see that the screen is actually a little bit smaller. And the resolution is much higher now. So that's that's looking good. And if we resize the screen should be able to resize the screen here. Then you notice that the size of the display actually changes as well. And that's what we should see. So whenever guest additions is installed properly, then you can basically maximize the screen size. And this is what we want. So that's it for installing guest additions into Kali Linux. Basically, we can just open up command line. We do not, you cannot install the normal way by going to devices, insert guest addition, addition CD image. We do not want to install this way. We need to install from the Kali repository in Kali. If this were a Linux system, then we need to insert guest addition CD image and then use the software that's in that CD, which we may do it another video on later. So that's it for installing guest additions into Kali Linux. Thank you very much. If you like this video, please subscribe for more.
