windows上的openssh設置：連接重置

我在我的 Windows 機器（Windows 10 Enterprise Edition OS）上使用 Hyper-V 設置了一個（Ubuntu）虛擬機，但似乎我的學校網路安全規則不允許我將網際網路共享到 VM，所以我想設置建立一個 ssh 隧道（允許在虛擬機上訪問網際網路，以便使用 輕鬆安裝包apt install）。

我在 windows 機器上安裝了 OpenSSH-Win64。但是當我嘗試從 ubuntu VM 連接時，它給了我錯誤：

我不知道在哪裡看。一些來自 Ubuntu VM 的檢查：

miranda@ubuntu-vm:~$ tcpdchk -v

我手動添加了一個包含hosts.allow以下C:\Windows\System32\drivers\etc內容的文件：

sshd: 150.203.213.248

它沒有任何區別。

這是一個已知問題，在此處進行了描述：

https://github.com/PowerShell/Win32-OpenSSH/issues/1027

執行 sshd 並收集日誌時，請確保您是 SYSTEM。

將最新版本的內容提取到 C:\Program Files\OpenSSH （確保二進制位置僅對 SYSTEM、管理員組具有寫入權限。經過身份驗證的使用者應該並且只有讀取和執行權限。）

就我而言，在為“經過身份驗證的使用者”分配“讀取和執行”權限後，它就可以工作了。

請參考安裝文件https://github.com/PowerShell/Win32-OpenSSH/wiki/Install-Win32-OpenSSH#install-win32-openssh-test-release
