我在 Windows 机器（Windows 10 企业版操作系统）上使用 Hyper-V 设置了一个（Ubuntu）虚拟机，但似乎我的学校网络安全规则不允许我将互联网共享到虚拟机，所以我想设置一个 ssh 隧道（允许虚拟机访问互联网，以便轻松安装软件包apt install）。
我在 Windows 机器上安装了 OpenSSH-Win64。但是当我尝试从 ubuntu VM 连接时，它给出了错误：

我不知道该看哪里。从 Ubuntu VM 进行一些检查：
miranda@ubuntu-vm:~$ tcpdchk
miranda@ubuntu-vm:~$ tcpdchk -v
Using network configuration file: (null)
miranda@ubuntu-vm:~$ ifconfig

hosts.allow我已手动添加了一个包含C:\Windows\System32\drivers\etc以下内容的文件：
sshd: 150.203.213.248
这并没有什么区别。
答案1
答案2
将最新版本的内容提取到 C:\Program Files\OpenSSH（确保二进制位置仅对 SYSTEM、管理员组具有写入权限。经过身份验证的用户应该且只能拥有读取和执行权限。
就我而言，在为“经过身份验证的用户”分配“读取和执行”权限后，它就可以工作了。
