Hello, everyone, and this is your instructor again, Emraan Eversole, and in this class or saying
this lesson, I'm going to cover the issues that you might be facing connecting to the anextra to Pudi.
Now, I do have a few students, very limited students who did experience some of the issues.
When they build a Linux VM, they install the operating system.
And then when it comes to the point when they use Pudi session to connect to the Linux to the next machine,
they are having issues.
So I'm going to quickly COHRE what could be the issues or how or what are the steps that can be taken
to resolve those issues.
Some of the issues, the primary ones is the next setting on the Oracle Warshel box.
So if you go to Oracle Virtual Box and go to network and there is a niche setting that you have to make
sure it is selected and it's configured the right way, we'll cover that later.
Then the advanced setting on the NEC on the same Oracle, a shoebox setting that will also covered here
as well.
And the third one is if the network interface is down at the operating system level, which means that
your next setting is perfectly fine at the Oracle virtual box level.
But on the operating system, the interface itself is down, so you will have to bring it up or restarted.
And the last one would be the S.H. Damon is not running on your next operating system, which is very,
very highly unlikely because by default, when you install Linux operating system in your machine,
the SSA is running anyway.
I am covering this just in case, just to make sure that you have you have went through all the different
troubleshooting steps.
So I have my next machine open.
I'll go over it and we'll cover all of these steps one by one.
So this is my next machine that's already up.
Now, the first thing that I have mentioned is Nick sitting on Oracle Virtual Box.
So now what is the next setting?
If you go to Oracle Virtual Box, which is this window, and from here you select your Linux machine
and then go to setting.
And then there is this option called network and this network option.
You have this adapter one, it says enable network adapter, make sure this is checked.
The reason you don't see on my Oracle box not checked or great out is because my machine is running
powered on.
If you power it off, you will have this enable network adapter checkbox option available to you.
So make sure it is checked.
The next thing you have to make sure is that you have hosted only adapter selected.
Now we have different options that will cover first.
One is cost only adapter, which means that you could connect only from your PC or on your laptop where
you're running this article or shoebox.
You will connect from that PC to your next machine and you can go out on the Internet.
And then on the name side, you have a virtual box host only Ethernet adapter.
There is no other option.
So by default, you have to select this one.
So when you have this host only adapter, then you click, OK, then you go back to your machine and
then you type if config or IP, whichever the command that is available to you, you hit and then you
will see if config.
The first interface that we are concerned about is this one.
And this is the part that you have to look into the other two ELO and we are B-R zero.
Just ignore that for now.
I have covered these two interfaces in my module seven.
You will learn that in module seven, what are these different options are used for.
But anyway, for now, just focus on this one, which is ENPI zero three.
And if you notice right here, the eye net right here it is the IP address of my Linux machine that
is given to me.
And also you have to verify that this interface is running up and running.
And if you have all the settings correct until now, but you still do not have an IP address right here,
which would be in a case like this, if you do if down ENP zero is three hit enter.
And now if I do have config, you'll notice I do not have that iiNet IP address.
Right.
So if that is your case, then what do you have to do is you either have to restart your network service
or simply to f up ENP zero has three hit enter lets you hit enter.
You'll see the connection successfully activated.
Now when you do if config or.
IP, and you will see that you have an IP address, one eight to one 68 56 one one, that's one way
of doing it.
The other way you could simply restart your network service, the command to do it.
A system, Ketel restart network DOT service and enter
it will bring down your interface and bring it back up and then you run if config and you will see you
have this IP.
Now by default, everyone should have the same IP address.
So you could just go into your PUDI machine temporary terminal and then you input the IP 192, dot 168,
dot 56 dot one o one.
And then you could simply click on Open and there you have your login prompt.
So that's how you actually create a connection between your position and your Linux machine.
So let me open up a new session here just in case.
Go onto the one.
So just close it.
So was this close to now?
The second option I wanted to COHRE is this one.
It says Advanced Nick Setting.
So what is advanced setting?
Sorry, one more thing before I go to advanced setting, let's go to the other setting.
Now, if you go to your VM and then click on network, there is attached to, there's another option.
So now if host only adapter option is now working for you, that is fine.
Don't worry about it.
It's not the end of the world.
Pick a different option, which is bridge adapter.
Pick that one now and bridge adapter.
As soon as you select big adapter, it's going to give you a different option for the name, which is
Intel or dual band wireless.
Now my laptop right now is connected to the Internet wirelessly through the Wi-Fi.
So make sure if that's your case, then you select Band Wireless.
If your machine, your PC or laptop is connected through the Ethernet cable, which is a physically
wired cable to the modem or router, then you will pick even a connection.
This is the one which is the Wired connection.
So you'll pick that anyway.
I had the wireless, I pick wireless and then you click OK, once you click OK, then you come back
to your Linux machine and then you do the same thing.
You restart your network service, which is system ctrl, restart, network service hit, enter
and you got your problem back now type IP config or so if confect hit enter and now you'll see you have
a different IP one eye to 161 dot eight.
Now this is the IP your Linux VM is getting from your modem in your house or at your work.
Now you could just simply go again into your PUDI session and now you could type one 92 one 68 one eight
and click open and it will give you the prompt back.
So this works the same way.
The only difference between hosts Only Adapter and Bridgid adapter is that bridge adapter will allow
you to communicate outside on the Internet.
So if you want to download anything or if you want to open up a Web browser on your Linux machine right
here, then you would need a bridge adapter.
But if you do not want to go outside, you just wanted to have a communication between your PC, where
you running this article or shoebox annualise machine and you pick host only that.
Now, that option I said that you could try out is the advanced setting.
When you click on add that drop down menu, make sure that Intel Pro 1000 empty desktop is selected
for the adapter type.
Now this is my adapter model that is inside of my laptop.
You might have a different model that represents your wi fi card.
So by default it should pick the the one that is attached to your card then promiscuous mode.
Lidell as Dinni That's fine.
That's a Mac address.
You don't have to change that.
Make sure the cable is connected.
And then again, of course, you hit OK and come back here and then you could try doing the same thing.
System ctrl restart network service.
Now what a system.
Ctrl command.
That is something that we will cover in module seven on.
The last one I have on my slide is.
SSA demon is not running now what what does it mean?
It means that when I go into my machine, all you have to make sure.
But again, as I said earlier, this is the chances of this not running is very, very slim, but still
verified.
And to verify that SFH demon process is running you Dupas minus if Piper and up S.H. minus EAF Pipe
and Greb.
S.H., what the hell is that?
Don't worry about it.
Just run this command.
You will learn this as you go on with my training.
I just want you to test these and see if you get this output.
And if you do get this output, especially this line that says user s been S.H. Dashti, this shows
that your demon are the process that is listening to accept your incoming traffic is running.
So that is perfect.
Now, in my case, is running.
In your case, it should be running in case it's not running, then I would say that you do system skil
restart ss SFH and then you hit enter.
Sorry, it's probably SS.
Yes.
So it will start back again.
Again.
It's the chassé.
Very slim, but you should try that too.
So anyway, these are the few troubleshooting tips.
If you still having issues connecting from Pudi to your Linux machine then don't worry about it.
Just send me an email.
I would prefer if you could send me a screenshot.
That'll be great and I will definitely help you.
