How to Create a Network of Machines in VirtualBox with SSH Access

In this video, we'll be learning how to clone Virtual Machines, add these machines to a network so they can communicate with each other, make sure they have internet access, and also set up SSH so that we are able to SSH into these machines from our host machine. This will allow us to pretty much build an entire virtual lab that we can use to test all kinds of different software. So after we're done, this will give us the ability to quickly spin up a new VM that behaves just like a real machine on our network. Let's get started.

I really enjoy the style of Corey Schafer, He always makes a complex question simple and clear. Thanks a lot. My hero.

[@SolomonSelvam]

Best Tuts so far i have watched for ssh, thank you so much man. this would be great help for the beginners

[@stephanesoren5014]

For those without "Host-Only-Networks" tab in their settings (Virtual Box 6.1.2) : Click on "File" then "Host Network Manager", then "Create"

[@amirsteinhart3301]

it returns an error

[@vincenzonatale8029]

It should be written on the video itself , because this comment about "Host-Only-Networks" is very important.

[@Ambient_Life]

@@amirsteinhart3301 reinstall or update virtual box, I had the same error then updating worked and I have noticed similar solutions at stackoverflow

[@AbhayGoyal]

So we dont need NAT then?

[@Petuhalwai]

Thanks a ton Corey for making such wonderful and helpful tutorial, after long search landed on this and made things working. Keep the good work posting... :)

[@NotMuchHere]

Thank you for providing this. I wanted to do host only networking but was clueless. This has been a great help.

[@PyMoondra]

Thanks for these -- Virtual Machines and networking are areas I really need to get acquainted with.

[@kiranaaditya5345]

Thanks for this video. Bless you. This is exactly what I needed. I was searching for a way to do this for 2 weeks.

[@Ambient_Life]

watched this entire video and gained so so much from it and it took literally 2 hours since I had to do research on troubleshooting but definitely something worth the time. great video Corey ❤thanks

[@kuperlen]

great tutorials, nicely paced and comprehensive, thanks!

[@clintonp8621]

Thank you Very much Corey! That was absolutely helpful..Was about to switch back to Vmware-workstation as I was familiar with that..

[@linix2954]

The /etc/network/interfaces file is no longer available in newer version. Ubuntu 18.04 and above uses netplan to configure your network. Netplan is used instead, the configuration file is in the /etc/netplan/ directory.

[@muhammadakmal1244]

thank you man. This video is clear and the explanation is the best. i subbed to you. You helped me finish my assignment which to copy some shit from one virtual machine to other vms. Thumbs up for the video .

[@luckbychance3179]

for some reason on my window pc VM preference i dont see the host only networks tab. But I can see in my PC network adapter section that Host Only Ethernet Network is present. Please explain reason for this.

[@hamiltonlima]

thanks :)

[@ganeshm4525]

Hi Corey, thanks for your very productive video. At minute 8.56, your duel hosts showing the result from ifconfig -a with enp0s3, .0, enp0s8 and lo. However, I do see enp0s3 and lo only.I went ahead and updated interfaces file, but that did not help. I appreciate your reply.

[@pavanscott]

Kindly add docker videos also 🙏 it's very helpful👍👌✌

[@bestfullapps110]

Ty

[@HPDStudios]

There are 2 interfaces the enp0s3 and enp0s8... I don't get how your interface file does not provide a specification for the enp0s3 yet somehow when you ifconfig -a it shows an ip assignment. ... I'm stuck at this stage for some reason... I just can't seem to match the enp0s3 and the enp0s8 to the appropriate Virtual Machine network adapter offering. Any insight on this would be useful... This essentially shuts down the NAT connection and I can't get any internet access to the server. Everything else is identical.

[@BrijeshYadav-vl7bj]

@Corey Schafer Is it possible to setup similar network using Bridge adapter and allocating static IP to each VMs?

[@raghavtalwar3962]

You saved my ass bro thank you so much

[@AbhayGoyal]

Which VM version are you using for your mac?

[@krishnaguru4483]

Why use NAT in one adapter and Host only in another? why not use bridged networking, will it not give access to both interconnection between VM and also internet? is there any advantage of using 2 adapters instead of one bridged networking?

[@kilianbrandt1069]

That was a great tutorial, thank you! I've got an extra question and hope someone can give me an hint. For example in the video ubuntu-1 git the IP: 192.168.56.100. There are 2 network adapters defined. As far as I understand NAT for internet and the second for the communication inside the vm network. Now the question: What would be the approach to connect and lets say ping ubuntu-1 from another physical machine (e.g. an Raspberry Pi), which is connected to the host pc? Do we need a third adapter allowing the connection between them?

[@srihariitsme]

To connect to your host pc - the one which is running virtual box, you need to change your network adapter1 setting from NAT to Bridged adapter.

[@Eggsec]

Wonder if I can have kali and Kioptrix machine in save network.. for pen practice?

[@squelchedotter]

Personally, I just use Vagrant. It's a nice wrapper around all of this VM stuff.

[@coreyms]

Yes, that's a good one to know. I've used it in the past and slowly got away from it. I'll probably try to start using it again in the near future and possible do some videos on it.

[@nouseofaname2010]

what if I only have one network adapter? Is there a way to set it up so that I can use my Ubuntu vm to ssh into my CentOS machine? Both currently have the same adapter with the same IP address. :/

[@ChangeMyBody94]

for some reason on my mac i dont see the host only networks tab

[@abhisheksaharan]

its under global tools on the top right. It has been changed with newer version.

[@pjmclenon]

hello thanx for the vid..how can we deply this cluster network on different actual physical machinses?/..i am still not ablle to do this..thxz alot...jessica

[@shun747]

So can this affect other devices that are not a VM across the internet as well?

[@amitbajpai6265]

How did you come out without saving the name of file in nano while changing the hostname

[@abdularif951]

I would appreciate, if you could show me how do make IP address of NAT interface card to static ?

[@ionutvali5295]

Thank you for the info and for the time, your videos are very easy to understand, But this is very old and all most no of the info it updated. I try with CentOS and i can ping from one machine to another right after install . So can you please do one update video but with CentOS. Thank you

[@pxl-cube]

2:49 There is no Host-Only-Networks tab in my settings :(

[@abhisheksaharan]

In mac its on top right corner under global tools

[@Daldavid]

How does the configuration differs in CentOS ? Especially when you edit the "eth0" and "eth1" files ? Thanks.

[@abhisheksaharan]

in centos you have to create a new file under vi /etc/sysconfig/network-scripts/ifcfg-enp0s8

[@vladyslavstadnyk9156]

why do you have 3 devices in ifconfig -a, and I have only lo and enp0s3?

[@eecopper670]

I'm trying to do this on Ubuntu 20.04.1 LTS (Guest) and Arch Linux (Host), however on the guest machine, /etc/network/interfaces has apparently been obsoleted. What should I do here? Does this only work with Ubuntu 16.04?

[@fernfaba]

/etc/network/interfaces is deprecated (google this for more info) I installed the following and it worked: -------- sudo apt install ifupdown

[@whoseversquare3214]

Why can I connect to Ubuntu-2 but not Ubuntu-1 when I am trying to ssh into it from the terminal on my computer?

[@kristiannn]

8:33 - ifconfig -a 9:30 - 11:44 14:50 - ssh from host into vm

[@zhencao6115]

Nice vedio Corey. Btw, why I can,t ping a virtual machine at my host machine. I also use mac os.

[@coreyms]

Hmm, there could be a lot of reasons it isn't working. Are you sure they're on the same Host-Only network and that you've set all of the static IPs correctly?

[@zhencao6115]

I will try tonight!. Thank you for your answer. Really love your tutorial. I enjoy one of your video per night. Thank you for sharing your knowledge and your skillful teaching technique!

[@mikesmith9538]

I have the same issue. I'm running Windows 10 on the host and I followed the directions explicitly and rechecked them many times. I can ping the host from the virtual machine, but I can't ping the virtual machine from the host. I can ping 192.168.56.1 from the host, but I can't ping 192.168.56.100 (the virtual machine) from the Windows 10 host. Do you have any idea what could be causing the issue? Mike

[@mikesmith9538]

I solved my issue. It was caused by the Windows 10 Firewall. This is what I did: Start Windows Firewall (Control Panel) Choose Windows Firewall Properties Choose - Domain Profile Tab Click Customize (Protected network connections Uncheck - Virtual-Host Only Network Click OK Repeat the above for the Private Profile and the Public Profile tabs Verify the Host can ping the VM. Go back and re-check the Virtual-Host Only Network to re-enable the Windows 10 Firewall. Verify the Host can still ping the VM. I don't know if leaving the Windows Firewall active for the Virtual-Host Only Network connection will continue to work, but now I know how to disable it.

Now, it has been three years since this video was created and a lot has changed since then. I couldn't do this on Ubuntu version 20 LTS since sudo nano /etc/network/interfaces command didn't work. So I have to install Ubuntu version 16 LTS to achieve it. Anybody knows how to do it on Ubuntu 20 or any newer tools to do this same thing? Thank you all

[@dinuzakbayev4349]

Can you learn creating a physical network of machines with this?

[@coreyms]

I have always used virtual machines so I don't really have the experience to say. I would assume the process is similar, but with some differences here and there. Someone more experienced in IT and small office networks could likely answer this better than myself though.
