我正在尝试通过Ansible配置运行OpenSSH（https://github.com/PowerShell/Win32-OpenSSH）的Windows节点。正常的SSH连接工作时，Ansible似乎无法连接到节点。
正常的SSH连接：

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

为什么连接无法通过Ansible工作？
答案 0 :(得分：1)
我相信来自Microsoft的人仍然没有解决文件描述符传递问题，因此ControlMaster函数可能无法正常工作，即使事先没有公布。如评论所建议的那样禁用它应该可以解决您的问题。您也可以在/etc/ansible/ansible.cfg中使用ansible配置：
ssh_args = -o ControlMaster=no
