您好，我需要帮助解决 Windows 10 操作系统上的 sshd 服务器或 ssh 客户端问题。
在以下部分检查--vvv选项输出的日志：

我还提供 EventViewer 日志：
之前安装的 openssh 服务器/客户端可能存在问题
因此还剩下 Openssh Server/Agent 服务。我查看了服务管理器。
虽然这可能不是问题的根源，因为在此之前没有更多不同版本的 Openssh 和代理的实例。
当您尝试使用该密钥时，问题就开始了。但还有很多其他问题，例如无法打开，例如权限不足。但它有：
注意：C:/Users/dsafg/.ssh/config 实际上并不存在。没有这个文件。
检查 ACL：一切都是完全控制，而不是某些授权用户组。
以下是 ProgramData 中 ssh_config 的内容：
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the

该连接仅通过密码验证才有效，而不是现在因尝试使用公钥连接而被禁用。
我只在本地主机上测试过，但它已经在 android wifi 客户端上测试过，但出现了同样的错误。我的 MS 帐户已添加到用户中，我希望这不是问题，因为之前它可以使用。
首先，请帮助我们完全卸载 openssh 的先前客户端实例，然后我们才能继续。
这有帮助：
$administratorsRule = 新对象 system.security.accesscontrol.filesystemaccessrule("管理员","完全控制","允许") $systemRule = 新对象 system.security.accesscontrol.filesystemaccessrule("系统","完全控制","允许") $acl.SetAccessRule($administratorsRule) $acl.SetAccessRule($systemRule)
