我不能在 WSL-Ubuntu 上使用 ufw

Question

我将 Windows 10 家庭版（内部版本 17134.471）与 WSL-Ubuntu 16.04（xenial）一起使用。

我执行apt update -y && ufw --force enable并得到以下跟踪（我不知道这意味着什么 - 也许缺少一些内核函数，因此一些失败的系统调用）。

无论如何，有没有办法像今天一样使用 WSL-Ubuntu？

痕迹：

Answer 1

因为你没有Linux内核。

ufw是 的前端netfilter。Netfilter 是用于过滤 IP 数据包的 Linux 内核支持。Windows 具有不同的机制，通常称为 Windows 防火墙。

ufw仅支持 netfilter，不支持 Windows 防火墙或其他 IP 过滤技术。因此，它仅适用于具有 Linux 内核的系统。

手册页提到了这一点：

This  program  is for managing a Linux firewall and aims to provide an
easy to use interface for the user.

有些工具确实不能移植到不同的平台。这包括ufw尝试连接操作系统内核的工具，例如。
