1.SetUp Hyper-V on Windows

Check if your system is compatible

Read:

• https://techcommunity.microsoft.com/blog/educatordeveloperblog/step-by-step-enabling-hyper-v-for-use-on-windows-11/3745905
• https://support.microsoft.com/en-us/windows/upgrade-windows-home-to-windows-pro-ef34d520-e73f-3198-c525-d1a218cc2818

To check if your system is compatible with Hyper-V, follow these steps:

1. Press the Windows key + R to open the Run dialog box.
2. Type msinfo32 and press Enter.
3. In the System Information window, scroll down to the "System Summary" section and look for the Hyper-V Requirements line. If it says "Yes", then your system is compatible

You can also check to see if the BIOS firmware has virtualization enabled by looking in the CIM_Processor class.

(Get-CimInstance win32_processor).VirtualizationFirmwareEnabled

True

Get-Service vmcompute

Status   Name               DisplayName
------   ----               -----------
Running  vmcompute          Service de calcul hôte Hyper-V

2.Enable Hyper-V on Windows 11

Once you have confirmed that your system is compatible, you can proceed to enable Hyper-V on your Windows 11 machine. Here's how:

1. Press the Windows key + R to open the Run dialog box.
2. Type appwiz.cpl and press Enter.
3. In the Programs and Features window, select Turn Windows features on or off in the left-hand pane.
4. In the Windows Features window, scroll down to Hyper-V and check the box next to it.
5. Click on OK and wait for the installation process to complete.
6. Once the installation is complete, click on Restart Now to restart your computer.

3.Configure Hyper-V settings

Run C:\WINDOWS\System32\mmc.exe

- Virtual switch: Hyper-V uses a virtual switch to connect virtual machines to your physical network. You can create a new virtual switch or use an existing one.
- Virtual machine settings: You can configure various settings for your virtual machine, such as memory allocation, processor allocation, and network adapter settings.
- Integration services: Hyper-V integration services enhance the performance and functionality of virtual machines. You can enable or disable integration services as needed.

Further resources surrounding the enablement of these resources can be found here: https://learn.microsoft.com/training/modules/configure-manage-hyper-v/?WT.mc_id=academic-89565-abartolo

With automation:

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -NoExit 
Get-ExecutionPolicy

New-VMSwitch -name XXXLabXXXExternalSwitch -NetAdapterName Ethernet -AllowManagementOS $true
Get-NetAdapter -Name * -Physical
New-VMSwitch -name DockerExternalSwitch -NetAdapterName Wi-Fi -AllowManagementOS $true

4.Install VS Code

Go to https://code.visualstudio.com/download

5.Install WSL2

Read https://aka.ms/wslinstall

Run Terminal :

wsl -l -v
wsl.exe --update

wsl.exe --list --online
wsl.exe --install Ubuntu-24.04
wsl.exe --install kali-linux

wsl -l -v
wsl date
# pour voir où le chemin du répertoire actif est monté dans WSL.
wsl pwd

/mnt/c/Users/yourusername

6.Update the list of the OS products

sudo apt-get update
sudo apt upgrade --yes

uname -a 

Linux westpoint 5.15.167.4-microsoft-standard-WSL2 #1 SMP Tue Nov 5 00:21:55 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

7.Prepare GitHub SSH Keys

Check the fingerprint of your SSH key in GitHub with the SSH Key used by git.

If your Git repo URL starts with HTTPS (ex: "https://github.com/<!XXXyour-git-homeXXX!/sec102.git"), git CLI will always prompt for password. When MFA is enabled on GitHub and that you plan to use SSH Keys, you have to use: git clone git@github.com:your-git-home/sec102.git

appName="sec102" 
echo "appName is : " $appName

# /!\ IMPORTANT : check & save your ssh_passphrase !!!
ssh_passphrase="<your secret>"
ssh_key="${appName}-key" # id_rsa

github_usr="<Your Git Hub Account>"
echo "GitHub user Name : " $github_usr 

git_url="git@github.com:$github_usr/$appName.git" # "https://github.com/$github_usr/xxx.git"
echo "Project git repo URL : " $git_url 

ssh-keygen --help # -t ecdsa -b 256
echo $HOME
mkdir ~/.ssh
ls -al $HOME
ssh-keygen -t rsa -b 4096 -N $ssh_passphrase -f ~/.ssh/$ssh_key -C "youremail@groland.grd"

# Check Private & Public Keys
ls -al ~/.ssh/
cat ~/.ssh/$ssh_key.pub

# Now add this PUBLIC Key to your GitHub Account as an Authentication Key: https://github.com/settings/ssh/new

# Create your Git Config

echo "
[user]
	name = bob.jojo
	email = bob.jojo@yourcorp.com
[core]
	editor = nano
	#sshCommand = ssh -i /c/Users/bob.jojo/.ssh/id_rsa
	sshCommand = ssh -i /c/Users/bob.jojo/.ssh/githubkey
	autocrlf = false

[alias]
	hist = log --all --graph --decorate --oneline

	# Put the certificate at C:\Users\~YourUserName\AppData\Local\Programs\Git\mingw64\ssl\certs

" >> $HOME/.gitconfig

cat $HOME/.gitconfig
# update the config as you need
vim $HOME/.gitconfig

git version
git config --list --global
# ssh -T $git_url -i /c/Users/bob.jojo/.ssh/githubkey

8.Change mount folder owner

Read :

• https://askubuntu.com/questions/911804/ubuntu-for-windows-10-all-files-are-own-by-root-and-i-cannot-change-it
• microsoft/WSL#7798

cat /etc/group | grep $USER
# get the group of your user, ex: 1000

# Check WSL conf:
cat /etc/wsl.conf

mount | grep -i C:
# uid=0;gid=0 means it is owned by root

ls -al /etc/wsl.conf
# sudo chmod g+w /etc/wsl.conf

# Add this section in /etc/wsl.conf
[automount]
enabled = true
options = "metadata"
mountFsTab = false

cat /etc/wsl.conf 

# remount to fix the issue
sudo umount /mnt/c; sudo mount -t drvfs C: /mnt/c -o metadata,uid=1000,gid=1000

9.Clone the repository

cd $HOME
git clone $git_url
cd $appName

At this step, you will be able to use git in WSL, but NOT from windows, if you want to leverage VSCode/Source Control view to push your code to GitHub, then you have to complete step 10 below.

10.Install Gitbash for Windows

Follow this instruction to install Choloatey (package manager for Windows)

@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

choco upgrade chocolatey
choco –version
choco --help

Install Git bash CLI with Chocolatey

choco install git.install --Yes --confirm --accept-license

Open Git Bash Windows Application, create SSH Keys in Git Bash like at step 7, also configure your .gitconfig like at step 7.

hostname
whoami
date
git version
git --help

Test a git clone and a git push to verify your SSH Keys

cd $HOME
git clone $git_url
cd $appName

. setEnv.sh

Run the script

bash ./rot13.sh encode --message "Hello WORLD 2025 !"
