A Vagrantfile that provides an enviroment for PXE boot, to solve problems with OS deployment.
If you don't have the needed tools, get them with the next comands
$ sudo apt update && sudo apt upgrade && sudo apt install vagrant && sudo apt install virtualbox
If you have issues installing Vagrant and Virtualbox at the same time, you will need to execute the following lines
$ sudo apt update && sudo apt upgrade && sudo apt install vagrant
$ wget -O- https://www.virtualbox.org/download/oracle_vbox_2016.asc
$ sudo gpg --dearmor --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpg
We will need to create a folder where we will store our Vagrantfile and everything we will want to sync with the virtual machine.
$ mkdir PXEBOOTvagrant && cd PXEBOOTvagrant
Then we will need to create the Vagrantfile, you can choose any text editor, in my case I will be using nano
$ nano Vagrantfile
After creating our Vagrantfile, we must paste the following code (Lines that start with "#" are comments, so they aren't needed)
#We set the number of client machines that we want
num_cli = 4
Vagrant.configure("2") do |config|
#We set the Server machine with the box that we want, I will be using debian/buster64 but you can choose any linux box in https://app.vagrantup.com/boxes/search
config.vm.define "server" do |subconfig|
subconfig.vm.box = "debian/buster64"
subconfig.vm.hostname = "server"
#We set the network in our machine, we will set a private network with the IP address that we prefer
subconfig.vm.network :private_network, ip: "192.168.100.5",
#We set a second adapter with a intnet of virtualbox
virtualbox__intnet: "lan1"
#Optional machine configurations
subconfig.vm.provider :virtualbox do |vb|
#We set an especific name for our Server machine
vb.name = "server"
vb.gui = false
end
#Then we set up the server that will be holding the netboot image
subconfig.vm.provision "shell", inline: <<-SHELL
sudo su -
apt update -y && apt upgrade -y && apt install -y dnsmasq
echo "dhcp-range=192.168.100.50,192.168.100.150,255.255.255.0,12h
dhcp-boot=pxelinux.0
enable-tftp
tftp-root=/srv/tftp" > /etc/dnsmasq.conf
mkdir /srv/tftp
systemctl restart dnsmasq
cd /srv/tftp
#The following line will define the OS that our clients will have, I will use kali, but you can set other OS with the links in OsNetbootLinks.txt on the top of the page
wget https://http.kali.org/kali/dists/kali-rolling/main/installer-amd64/current/images/netboot/netboot.tar.gz
tar -zxf netboot.tar.gz && rm netboot.tar.gz
SHELL
#Once we have our server up, we set up our clients
end
#We set a loop with the number of clients that we defined at the top of the file
(1..num_cli).each do |x|
config.vm.define "client#{x}", autostart: false do |cli|
#We define a empty box prepared for pxe
cli.vm.box = "TimGesekus/pxe-boot"
cli.vm.hostname = "client#{x}"
#We set up the network of our VM, we need a private dhcp network with a lan and we will set in the first adapter of our machine
cli.vm.network "private_network", type: "dhcp",
:adapter => 1, virtualbox__intnet: "lan1"
#Lastly we will set the name of our client machine and we auto show it when we do vagrant up
cli.vm.provider :virtualbox do |vb|
vb.name = "client#{x}"
vb.gui = true
end
end
end
end
After setting up our Vagrantfile we vagrant up our Server
$ vagrant up
The Server will delay several time to init because it has to download and transfer the needed files
When it finishes, we can vagrant up our clients.
$ vagrant up client1
In this case I only launched client1, but you can also launch client2,client3.... (The number of clients that we can launch is set up on top of the vagrant file "num_cli = x ")
When the machine sets up, it will pxe boot with an installer of the OS that we set up in the provision of the Server in our Vagrantfile If the OS that you need inst in our file, you can easily search "exampleOS" netboot and get the link that you need
