wsl-ssh-amb

This little program invokes wsl ssh or ssh.exe by detect ssh-target has special prefix (or not).

Build

Please build for Windows target.

In WSL (or in Linux)

GOOS=windows GOARCH=amd64 go build .

In Windows

go build .

Settings

VSCode

Settings.json

{
  "remote.SSH.path": "C:\\path\\to\\wsl-ssh-amb.exe",
  "remote.SSH.remoteServerListenOnSocket": true
}

I don't know what remoteServerListenOnSocket actually does. But, without this, Remote-SSH fails with various errors.

• failed to install vscode-server to remote
• failed to establish socket between local and remote
• etc.

SSH config

You need to add dummy target to Windows side config. Dummy must be correspond to WSL side config.

For example, if you set target like this in WSL,

Host foo
    HostName foo.example.com
    User tbistr
    IdentityFile ~/.ssh/id_rsa
Host bar
    HostName bar.example.com
    User tbistr
    IdentityFile ~/.ssh/id_rsa
    ProxyCommand ssh -W %h:%p foo

add dummy like this in Windows.

Host wsl_foo
Host wsl_bar

The default prefix is wsl_.

Background

VSCode Remote-SSH Extension uses Windows ssh.exe and config file. You cant use WSL ssh, .ssh/config and keys. The problem was reported by this issue.

Great workaround is provided by this gist. However, this approach completely switches to use wsl ssh. I want to switch wsl ssh and ssh.exe depend on target. (I use vagrant (virtualbox) on Windows and use vagrant ssh-config >> ~/.ssh/config to access VMs.)

This little program invokes wsl ssh or ssh.exe by detect ssh-target has special prefix (or not).
