SSH远程连接Windows子系统Ubuntu 22.04

安装完Windows子系统，然后安装ssh服务并启动子系统的ssh服务

$ sudo apt-get install openssh-server
$ sudo service ssh start
$ service ssh status
* sshd is running
 

查看子系统的ip地址：192.168.148.2

4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:3d:41:cf brd ff:ff:ff:ff:ff:ff
    inet 192.168.148.2/20 brd 192.168.159.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fe3d:41cf/64 scope link 
       valid_lft forever preferred_lft forever
       

假设你的Windows的ip地址为：192.168.3.24，默认情况下外界是无法直接通过 192.168.148.2 访问子系统 Ubuntu 的，需要在Windows上做一个端口转发、防火墙放行：

netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=22 connectaddress=192.168.148.2 connectport=22


netsh advfirewall firewall add rule name=WSL2 dir=in action=allow protocol=TCP localport=22

最后局域网的其他机器就登录啦：

[yzy@yzym ~] ssh goldtools@192.168.3.24
