Come on.
OK.
And then we're going to learn how to restart and shut down your computer.
OK.
Or your server.
And also we're going to learn how to install the guest additions.
OK.
Inside this Ubuntu Linux server.
OK.
So let's see step by step.
All these commands.
So before actually performing any operation we need to connect them to the Internet.
OK.
So after installing virtual box actually medically configured for the Internet if you're not getting
Internet into the watch box.
OK.
What do you need to do is first select the operating system from this list here and then click on settings
and here click on network.
OK.
And here make sure you have selected the next option.
Ok amongst all these options you should be selected this that option and this option should be checked.
At this point and click OK and after that Google file preferences and here just click on that in this
that network to make sure this option is present here and it should be checked out.
And if you do not get this option here then just click on this button that this will add this option
at this point.
And after that just click on this host to make sure this virtual box has so little that are kept that
option should represent here.
And of the conference this.

So now let's move on to our virtual server.
So now let's talk about the Suda.
So what is pseudo pseudo stands for super user do or substitute user do sudo is.
C'mon is a powerful tool.
OK.
Which users do administrators level privileges.
OK.
What that means is ok I suppose you are a normal user normal user on the server.
And if you don't do exec you some sort of commands and you are trying to execute that.
So what happens is that one cannot be executed.
It gives you the error that you don't how the admin is to do well fruitage execute the command.
That means you do not have that right exec come on.
But sudo can do that right.
Or the administrators will privilege to execute the come on.
OK so if you are not a super user or root user OK within the next list and about what is the root user.
But for just and then you can exec you at once.
Come on.
OK.
With the help of sudo You can also install software on various packages with the help of pseudo Sulu's

OK but the current version that we are using is Dola Pratt maintained by Todd Miller.
So let's get started with sudo.
OK.
First of all of installing overdrew server or a Linux system you need to update all the packages.
OK so who do this.

OK which are present in the root directly.
OK to good this operation you can press control see.
Let me show you again.
Type 3 and I'm going to press conference see the operation is paused here.
So in this way you can install any command which is not already present there.
OK on the Ubuntu server with the help of sudo and then you can perform the operation.
You can cancel any operation at any time by pressing the control c key.
So just clear the screen.
OK let's get to the whole.
The next thing that I would like to show you here is installing guest additions.
