Download the WSL 2 Image​

Download the Rocky Linux container image from the following URL:

https://dl.rockylinux.org/pub/rocky/8/images/x86_64/Rocky-8-Container-Base.latest.x86_64.tar.xz

Reference: https://docs.rockylinux.org/8/guides/interoperability/import_rocky_to_wsl/

Extract the Image​

Extract the .tar.xz file and convert it into a .tar archive.
WSL2 can import .tar files directly.

cd ~/Downloads

xz -d Rocky-8-Container-Base.latest.x86_64.tar.xz

Note: The built‑in Windows bsdtar cannot extract this file.
If the xz command is not available, install it via Cygwin64 or use another WSL distribution.

Import the Image into WSL2​

wsl --import RockyLinux-8.10 $HOME .\Rocky-8-Container-Base.latest.x86_64.tar --version 2

Verify the Imported Image​

wsl -l -v

# Open ~/.bashrc
code ~/.bashrc

Add the following:

export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"

eval "$(pyenv virtualenv-init -)"

Download the install script​

wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh

Make the install script executable​

chmod +x ./dotnet-install.sh

Install the dot.net SDK​

./dotnet-install.sh

To install the latest version​

./dotnet-install.sh --version latest

Add to path​

Open $HOME/.bashrc and add the following:

export DOTNET_ROOT=$HOME/.dotnet
export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools

Step1. Install OpenSSH Server on WSL​

Install OpenSSH Server on WSL2. Also, start the sshd service.

# WSL2 side
sudo apt install openssh-server
sudo service sshd start

Step2. Register the public key on the Windows side​

If you have not registered the public key on Windows, run the following command.

# Windows side
ssh-keygent -t ed25519

Next, register the public key on WSL2.

# Windows side
$pubkey = $(cat $HOME\.ssh\id_ed25519.pub)
wsl -- echo $pubkey `| tee -a `$HOME/.ssh/authorized_keys

Step3. Tunnel with SSH​

Connect to WSL2 from Windows via SSH.

# Windows side
ssh (wsl -- hostname -I).trim() -g -L8081:localhost:8080

Explanation of the command:

• (wsl -- hostname -I).trim() retrieves the IP address of WSL2.
• -g forwards the port to the LAN (accessible from external devices with an address like 192.168.x.x).
• -L is the local forward option. It forwards the server's port to a local port.
• 8081 and localhost:8080 mean that accessing http://localhost:8081 will forward to localhost:8080. Here, localhost refers to localhost as seen from the server side.

Step4. Start the server​

Start the server that you want to expose on WSL2.

# WSL2 side
ruby -run -e httpd . # Directory listing will be exposed

Step5. Access the server​

You can access the service at http://localhost:8081 or http://<IP address displayed by ipcconfig>:8081.

A disadvantage of tunnel connections is that it is tedious to tunnel every time. Although unstable, you can do the same thing by using netsh interface portproxy ~.

Disabling automatic generation of /etc/resolv.conf​

Edit /etc/wsl.conf as follows:

[network]
generateResolvConf = false

Creating /etc/resolv.conf​

For example, if the DNS server is 1.1.1.1, edit /etc/resolv.conf as follows:

nameserver 1.1.1.1

Preventing Deletion​

/etc/resolv.conf is deleted when WSL2 is restarted. To prevent this:

sudo chattr +i /etc/resolv.conf

Reference

• WSL 2 keeps overwriting resolv.conf
