【wsl2】ssh批处理实现一键固定ip

运行如下命令，即可一键启动ssh并为子系统分配固定ip，以192.168.169.2为例：

@echo off
setlocal enabledelayedexpansion

wsl.exe -d ubuntu-22.04 -u root -- service ssh start

:: set wsl2 ip
wsl -u root ip addr | findstr "192.168.169.2" > nul
if !errorlevel! equ 0 (
    echo wsl ip has set
) else (
    wsl -u root ip addr add 192.168.169.2/28 broadcast 192.168.169.15 dev eth0 label eth0:1
    echo set wsl ip success: 192.168.169.2
)

:: set windows ip
ipconfig | findstr "192.168.169.1" > nul
if !errorlevel! equ 0 (
    echo windows ip has set
) else (
    netsh interface ip add address "vEthernet (WSL)" 192.168.169.1 255.255.255.240
    echo set windows ip success: 192.168.169.1
)
