wsl-win32-openssh-agent

A set of systemd units to forward SSH agent socket from Windows to WSL.

Requirements

• WSL
  • systemd
  • OpenSSH
• Windows
  • npiperelay
    • Install: scoop install extras/npiperelay
  • Win32-OpenSSH

NOTE: The OpenSSH agent protocol has changed in version 8.9. If OpenSSH v8.9 or later is installed in WSL and the Win32-OpenSSH is older than v8.9, the agent will not work. You can check the versions by running ssh -V in WSL and PowerShell.

If you are using an older version of Win32-OpenSSH, you can install the latest version with the following commands:

Remove-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0
Remove-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
winget install "openssh beta"

You might need to restart the computer after running these commands to update the PATH.
