无法从 WSL2 访问网络 [英] unable to access network from WSL2
问题描述
我无法从 WSL2 子系统访问我的家庭网络.我安装了 Ubuntu.
I am unable to access my home network from WSL2 subsystem. I have Ubuntu installed in it.
anirban@Desktop:/mnt/g/BASH_WORKSPACE$ lsb_release -a No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
anirban@Desktop:/mnt/g/BASH_WORKSPACE$ uname -r 4.19.57-microsoft-standard
WSL2 中的 eth0 具有以下配置:
The eth0 in WSL2 has the following config:
anirban@Desktop:/mnt/g/BASH_WORKSPACE$ ifconfig

来自 WSL2 的路由没有默认路由.所以，我添加了一个默认路由，通过 eth0.
The routes from WSL2 did not have a default route. So, I added in a default route, through eth0.
anirban@Desktop:/mnt/g/BASH_WORKSPACE$ ip route
172.20.208.0/20 dev eth0 proto kernel scope link src 172.20.213.230
anirban@Desktop:/mnt/g/BASH_WORKSPACE$ sudo ip route add default dev eth0 anirban@Desktop:/mnt/g/BASH_WORKSPACE$ ip route default dev eth0 scope link
172.20.208.0/20 dev eth0 proto kernel scope link src 172.20.213.230
Windows 中的 vEthernet 具有默认配置，并且令人惊讶地不属于 WSL 的子网.
The vEthernet in Windows has the default config, and surprisingly does not fall within the subnet of the WSL.

有人对可能是什么问题有任何线索吗?注意:我的 wifi 显然可以访问互联网，我正在尝试从 WSL2 子系统 ping 8.8.8.8 以检查互联网连接.我使用的是 Windows 预览版 10.0.18956
Anybody has any leads on what the problem could be? Note: My wifi obviously has internet access, and I am trying to ping 8.8.8.8 from WSL2 subsystem to check for internet connectivity. I am using Windows Preview build 10.0.18956
谢谢，
推荐答案
我遇到了同样的问题，并且能够通过运行以下命令使其再次工作(我从其他地方得到的，抱歉我不记得在哪里):
I had the same issue and was able to make it work again by running the commands below (I got this from somewhere else, sorry I don't remember where):
在 wsl 中
修复网络问题，删除自动生成的文件
[root@PC-NAME user]# rm /etc/resolv.conf || true
[root@PC-NAME user]# rm /etc/wsl.conf || true
启用更改/etc/resolv.conf，启用 Windows 驱动器上的扩展属性
[root@PC-NAME user]# cat <<EOF > /etc/wsl.conf
[network]
generateResolvConf = false
[automount]
enabled = true
options = "metadata"
mountFsTab = false
EOF
使用谷歌域名服务器进行 DNS 解析
[root@PC-NAME user]# cat <<EOF > /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
EOF
退出 Linux WSL
在 Windows 中，cmd 作为管理员:
wsl --shutdown
netsh winsock reset
netsh int ip reset all
netsh winhttp reset proxy
ipconfig /flushdns
Windows 搜索 >网络重置
