Régler problème internet WSL

https://github.com/microsoft/WSL/issues/4731 https://gist.github.com/mandeepsmagh/f1d062fc59e4e6115385c2609b5f0448 https://www.tecklyfe.com/how-to-fix-no-internet-connection-in-wsl/

• Désactiver toutes les interfaces réseau (Wi-Fi, VPN) à l'exception de l'interface que je veux qu'Hyper-V utilise (Ethernet)
• netsh int ip reset, netsh winsock reset
• Désinstaller Hyper-V, WSL et tous les composants associés, redémarrer, réinstaller les composants.
• Arrêter les services cmdservice, hns, vmcompute, lxssmanager et redémarrer ces services.

Restart les services de containers :

sc stop cmservice
sc stop hns
sc stop vmcompute
sc stop lxssmanager
netsh winsock reset
netsh int ip reset all
netsh winhttp reset proxy
ipconfig /flushdns
sc start cmservice
sc start hns
sc start vmcompute
sc start lxssmanager

Etaindre WSL :

wsl --terminate Ubuntu
wsl --shutdown

Relancer une machine.

Script pour toute relancer :

if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process (Get-Process -Id $PID | Select-Object -ExpandProperty Path) "-NoProfile -ExecutionPolicy Bypass -File `"$PSCommandPath`"" -Verb RunAs; exit }

Write-Output "Shutting down WSL..."
wsl --shutdown

Write-Output "Stopping services..."
Stop-Service cmservice
Stop-Service hns
Stop-Service vmcompute
Stop-Service lxssmanager

Write-Output "Starting services..."
Start-Service lxssmanager
Start-Service vmcompute
Start-Service hns
Start-Service cmservice

Write-Output "DONE!"
Read-Host "Press ENTER to continue..."

Dans windows, créer %USERPROFILE%.wslconfig Désactiver le cryptage et la compression des fichiers :
pour %TEMP% - le fichier d'échange qui s'y trouve par défaut
Ou spécifier où sauvegarder dans %USERPROFILE%\N- wslconfig et désactiver à cet endroit :

[wsl2]
...
swapFile = E:\\Temp\\swap.vhdx
...

Disable encryption and compression on directories with distributions:

%appdatalocal%\Packages\CanonicalGroupLimited.Ubuntu*
%appdatalocal%\Packages\TheDebianProject.DebianGNULinux* 

Solution 2

Le resolvonf

• Effectuez les étapes ci-dessus pour modifier le serveur de noms dans le fichier /etc/resolv.conf.
• Exécutez ces deux commandes qui créeront un fichier /etc/wsl.conf et ajouteront quelques paramètres :
  sudo bash -c 'echo "[network]" > /etc/wsl.conf'
  sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
• Dans une invite de commande administrateur, exécutez wsl -shutdown.
• Redémarrez votre image WSL Linux et vous devriez toujours avoir accès à Internet.

1. Inside WSL2, create or append file: /etc/wsl.conf

2. Put the following lines in the file in order to ensure the your DNS changes do not get blown away

   sudo tee /etc/wsl.conf << EOF
   [network]
   generateResolvConf = false
   EOF

3. In a cmd window (!!), run wsl --shutdown

4. Start WSL2

5. Run the following inside WSL2 (line with search is optional)

   sudo rm -rf /etc/resolv.conf
   sudo tee /etc/resolv.conf << EOF
   search yourbase.domain.local
   nameserver 8.8.8.8
   nameserver 1.1.1.1
   EOF

Solution 3

Fix github script test :

Assuming you have followed all the steps to install / setup WSL2 -> https://docs.microsoft.com/en-us/windows/wsl/install-win10

**Tested on Ubuntu 20.04**

Step 1 - Find out default gateway and DNS servers
- Navigate to `Control Panel\Network and Internet\Network Connections`
- Right click on relevant connection type WiFi or Ethernet and select `Status`
- Status screen will be displayed, click on `Details` button
- Network Connection details screen will be displayed
- Note down `IPv4 default gateway` and `IPv4 DNS Servers` if available

                       **OR**
- Run following command from powershell or cmd
  `ipconfig /all`
- Note down `Default Gateway` and `DNS Servers` for relevant connection type WiFi or Ethernet

Step 2 - Create `wsl.conf` file
- Login to WSL2 and create sudo vi `/etc/wsl.conf` with following content
``
[network]
generateResolvConf = false

``
- Save file.

Step 3 - Delete current `resolv.conf` file
`sudo rm /etc/resolv.conf`

Step 4 - Create new custom `resolv.conf` file
- Use below command to create new file
`sudo vi /etc/resolv.conf`
- enter default gateway and any `IPv4 DNS servers` like below example

``
nameserver 192.168.1.254
nameserver 192.165.1.251

``
- Save file

Step 5 - Restart WSL2
- Open powershell and run following command
`wsl --shutdown`

Step 6 - Test internet connection in WSL2 
- ping google.com, it should work now.
