wsl2+kali-rolling+win kex+Connection refused 10061

wsl2+kali，可以在win10下运行一个效率高于virtualbox等虚拟机的linux，kali-win-kex基于VNC(In computing, Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.)，可以提供一套GUI系统，虽然不如原生的好看，但是还是可以用的。
我使用的是win10版本为20H2，默认启动kex会报10061的错，后面需要特殊处理一下，

kali win kex

sudo apt install -y kali-win-kex

        Usage:
                kex <mode> <command> <parameters>

                Mode:
                --esm            : Launch KeX desktop in a dedicated window using Windows native RDP
                --sl             : Seemlessly integrate KeX into the Windows desktop
                --win            : Launch KeX desktop in a dedicated window

                Command:
                [none]           : start KeX server and launch KeX client
                --start          : start kex server
                --start-client   : start kex client
                --stop           : stop kex server
                --status         : show kex server status
                --kill           : stop kex server and kill all related processes
                --passwd         : set kex server password
                --wtstart        : start kex server and launch win-kex client
                                   in Windows Terminal session
                --start-sound    : start Windows sound server
                --stop-sound     : stop Windows sound server
                --help           : display help
                --version        : display version

                Parameters:
                -i               : Use container IP address instead of "localhost"
                -m               : Optimized for Multiscreen (Win mode only)
                -s               : Sound support

        Examples:
                kex -s           : Start KeX server in window mode and launch KeX client with sound support
                kex --sl -s      : Start KeX in seemless mode and launch KeX client with sound support
                kex --esm -i -s  : Start KeX in ESM mode with arm workaround and launch KeX client with sound support
                sudo kex         : Start KeX server as root in window mode and launch KeX client

直接执行

kex -s

报如下的错误，

此时需要执行以下命令，不让VNC只接收本机的数据包(wsl2和win10 ip是两个网段)，

# [-localhost [yes|no]]    if enabled, VNC will only accept connections from localhost.
vncserver -localhost no
kex -s

再次执行后，一切正常！

如果需要从GUI退出，可以按F8，然后Exit Viewer，否则再次进入的时候又会报错。如果报错，可以再次执行vncserver的命令。
