windows - 无法获得公钥登录以在 Windows 10 ssh 服务器上工作

Question

我已经安装了 Windows 10 ssh 包并设置了 sshd。使用密码登录效果很好，但我无法使用公钥登录。我也一样 authorized_keys文件在 .\ssh\authorized_keys就像我在公钥登录效果很好的 Linux 机器上一样。我也跑了:

PS C:\Users\ffoobar> Repair-AuthorizedKeyPermission .\.ssh\authorized_keys
  [*] .\.ssh\authorized_keys

'NT SERVICE\sshd' needs Read access to '.\.ssh\authorized_keys'.
Shall I make the above change?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): y
'NT SERVICE\sshd' now has Read access to '.\.ssh\authorized_keys'.
      Repaired permissions

PS C:\Users\ffoobar> Repair-AuthorizedKeyPermission .\.ssh\authorized_keys
  [*] .\.ssh\authorized_keys
      looks good

PS C:\Users\ffoobar> 

在 C:\ProgramData\ssh\sshd_config , 我设置 PubkeyAuthentication yes .

尝试登录会给出:

Windows 事件日志不包含任何有用的信息。换 SyslogFacility或 LogLevel从默认值导致 sshd 无法启动。

Answer 1

显然，默认情况下它必须是 C:\Program Data\ssh\administrators_authorized_keys
此外，您需要确保此文件具有有限的权限。作为管理员，删除对文件的继承权限:
C:\ProgramData\ssh> icacls administrators_authorized_keys/inheritance:r
然后手动为系统和管理员添加读取权限。
