Mac OS 修改ip

使用vnc远程修改IP v4会：报无效的服务器地址 BasicIPv6ValidationError

所以还是用命令吧！设置IPv4地址
终端输入：networksetup -setmanual Ethernet 192.168.31.2 255.255.255.0 192.168.1.1
对应网卡设备、IP地址、子网掩码、网关
为什么是“Ethernet” 看下面

先ifconfig查看网卡文件，如下好多网卡文件，这样问题来了、要修改那个？？？

我们可以使用：networksetup -listallhardwareports网卡设备使用的网卡文件

ptr:~ roothost$ networksetup -listallhardwareports

好吧，原来是 Ethernet、Wi-Fi、Bluetooth、Thunderbolt等 设备使用对应的网卡文件

因为是接网线的，所以我们修改 Ethernet 以太网就有线网卡这个。

当然也可以这样：
终端输入：networksetup -setmanual en0 192.168.31.2 255.255.255.0 192.168.1.1
我表示没有测试过
