The error 'CreateProcessW failed error:2, posix_spawn: No such file or directory' occurs when attempting to use SSH with a jump host on Windows 10 without WSL. This issue affects users who are trying to connect to remote machines using the built-in SSH client in Windows 10.

This error can be frustrating for users who rely on SSH for remote access, as it prevents them from establishing connections to their remote hosts. In this guide, we will explore the root causes of this error and provide two methods to resolve the issue.

⚠️ Common Causes

  • The primary reason for this error is that the OpenSSH binary in Windows 10 does not support the -J option by default. The -J option allows SSH clients to use a proxy or jump host to connect to remote machines. Since WSL (Windows Subsystem for Linux) is not enabled on your system, you cannot use the built-in SSH client with the -J option.
  • An alternative reason for this error could be that the OpenSSH binary in Windows 10 is not properly configured or updated. It's possible that the binary is missing certain dependencies or has incorrect configuration settings, leading to the failure of the CreateProcessW function.

✅ Best Solutions to Fix It

Using a third-party SSH client

  1. Step 1: Download and install a third-party SSH client on your Windows system. Some popular options include PuTTY, WinSCP, or Git Bash. These clients provide support for the -J option and can be used to establish connections to remote machines using a jump host.
  2. Step 2: Configure the third-party SSH client to use the built-in OpenSSH binary as the SSH server. This will allow you to use the -J option with the OpenSSH binary, even though it does not support it by default.
  3. Step 3: Use the third-party SSH client to establish a connection to your remote machine using the jump host. The -J option should now work correctly, allowing you to connect to your remote machine.

Enabling WSL and using the built-in SSH client

  1. Step 1: Enable WSL on your Windows system by running the following command: `enable-wsl` in the Command Prompt. This will enable WSL and allow you to install a Linux distribution on your system.
  2. Step 2: Install a Linux distribution on your system using WSL. Some popular options include Ubuntu, Debian, or Kali Linux. Once installed, you can use the built-in SSH client to establish connections to remote machines using the -J option.
  3. Step 3: Configure your jump host and remote machine to use the built-in SSH client with the -J option. This will allow you to establish connections to your remote machine using a jump host.

💡 Conclusion

To resolve the 'CreateProcessW failed error:2, posix_spawn: No such file or directory' issue when using SSH with a jump host on Windows 10 without WSL, you can try either installing a third-party SSH client and configuring it to use the built-in OpenSSH binary, or enabling WSL and using the built-in SSH client. Both methods should allow you to establish connections to your remote machine using a jump host.
