从Linux到Windows 10设置无密码SSH

Question

我正在尝试设置一个从linux服务器到windows计算机的无密码ssh路径。我目前在windows机器上运行MobaSSH。我可以将ssh从linux服务器转到windows机器，执行命令也很好，但我必须输入密码。

我在linux系统上创建了一个公共RSA密钥，并使用WinSCP将文件复制到C:\Users\MyUserName.ssh文件夹，并在windows机器上重新启动MobaSSh服务。

没有密码它还是不会让我进去的。我在这里错过了什么？任何帮助都会受到极大的赞赏。

OpenSSH适用于Windows 10，对我来说非常可靠。我可以在没有密码的情况下持续地从Linux机器连接。这里是如何设置它。

• 升级到Windows 10版本1809或更高版本

- check via: `powershell -c "(Get-Item 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion').GetValue('ReleaseID')"`; see also `systeminfo | findstr /B /C:"OS Name" /C:"OS Version"` for Pro vs. Home, build number
- upgrade via Windows Update settings or [Download Windows 10](https://www.microsoft.com/en-us/software-download/windows10) (the latter works around an issue where some systems are [stuck at 1803](https://www.reddit.com/r/windows/comments/c3anuk/still_on_1803_and_check_for_updates_still_not/))

​

• 将SSH客户端和服务器(作为管理员；来源) -安装在PowerShell中

Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
Start-Service sshd  # remote login should be possible following this command
Set-Service -Name sshd -StartupType 'Automatic'
Get-NetFirewallRule -Name *ssh*  # there should be a firewall rule named "OpenSSH-Server-In-TCP"  # optional
Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0  # optional

• 从Linux命令行来源为管理员()启用公钥登录

scp ~/.ssh/id_rsa.pub administrator@remote_computer_name:'C:\ProgramData\ssh\administrators_authorized_keys'  # if using an alternate method, ensure file is not UTF-16 encoded
icacls C:\ProgramData\ssh\administrators_authorized_keys /remove "NT AUTHORITY\Authenticated Users"
icacls C:\ProgramData\ssh\administrators_authorized_keys /inheritance:r
get-acl C:\ProgramData\ssh\ssh_host_dsa_key | set-acl C:\ProgramData\ssh\administrators_authorized_keys

• 为非管理员启用公钥登录( in PowerShell )

Install-Module -Force OpenSSHUtils -Scope AllUsers  # for: Repair-AuthorizedKeyPermission
cd C:\Users\...
ssh-keygen  # create ~/.ssh
# add key(s) to ~/.ssh/authorized_keys
$ConfirmPreference = 'None'; Repair-AuthorizedKeyPermission -FilePath .ssh\authorized_keys
# if above fails, try ''%%Set-ExecutionPolicy Unrestricted -Scope CurrentUser%%''; see also https://github.com/PowerShell/Win32-OpenSSH/issues/1245#issuecomment-440388604
