Two Machine Virtual Network With Debian 11 Bullseye and Vagrant
Start a two computer virtual network in minutes.
- Automatically sets up Virtualbox machines
- Automates SSH login
- No graphical user interface is needed
With Debian and Ubuntu, it's easy
$ sudo apt-get update $ sudo apt-get install vagrant virtualbox
With Mac and Windows, you should download the installers and next-next a couple of times.
Create a new directory for your project, and save this Vagrantfile into it.
$ mkdir twohost/; cd twohost/ $ nano Vagrantfile

Enjoy your two hosts
You can ssh login to a host with
$ vagrant ssh t001
And exit back to your host OS
Both hosts can connect to each other and the Internet.
$ vagrant ssh t001 vagrant@t001$ ping -c 1 192.168.88.102 vagrant@t001$ ping -c 1 220.127.116.11 # Google nameserver vagrant@t001$ exit $ vagrant ssh t002 vagrant@t002$ ping -c 1 192.168.88.101 vagrant@t002$ exit
Best part, it's so quick and easy you can just destroy your virtual machines and start fresh.
$ vagrant destroy # all files on both virtual machines are destroyed
And then get fresh, empty machines
$ vagrant up
Nice way to practice: got something working? Now destroy the machines, do it again from scratch. Rinse and repeat.
Got it working? How do you like it? Feel free to comment below.
