Do you want to do remote development on your WSL2 container in Visual Studio Code? Read this.
- On the host set up OpenSSH for Windows
- Run
wsl --update
to make sure you are running the latest WSL - Open WSL and install another SSH server inside WSL with
sudo apt-get install openssh-server
- Now run
sudo systemctl enable --now ssh
to automatically start ssh when WSL starts. - On the remote machine run
ssh -J windows_user@windows_ip wsl_user@localhost
to see if the proxy jump will work
If you see the bash prompt it works. You can add it to the ~/.ssh/config file on the remote machine.
Host remote-wsl
HostName localhost
User wsl_user
ProxyJump windows_user@windows_ip
StrictHostKeyChecking no
Now connect with ssh remote-wsl
.
SSH to your Windows host (SSH Server must be installed in Windows Features)
ssh user@windowshost
Start Powershell
powershell
Run this command to switch SSH from CMD to WSL
New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\WINDOWS\System32\bash.exe" -PropertyType String -Force
ssh user@windowshost
You should now see WSL2 instead of CMD
At this point you can connect to your Win10 host with Remote SSH in VSCode with your Windows username and pw. But you'll actually start and connect to WSL2.
- Install the Remote - SSH extension
- Add a new SSH target and connect with your Windows host, username and password (you will automatically log in as the Linux user)
The workaround was inspired by: https://www.hanselman.com/blog/the-easy-way-how-to-ssh-into-bash-and-wsl2-on-windows-10-from-an-external-machine
Well, I ended up trying it out, but I'm not sure its what I want. Because Windows's SSH daemon is whats brokering the VSCode client, the file system scope is from Window's FS. I've a lots of performance issues running linux binaries on Window's FS, because its translating through a some kind of quasi-network share between the Linux VM and Windows FS. When connected this way, I'm not able to mount VSCode on folders that are inside the Linux VM it appears.
I'm setting up an SSH tunnel from my remote machine, where the tunnel has windows point to the Linux's SSH server, and VS code is connecting to that.
This way VSCode is mounted inside the VM natively with better IO performance.
