OpenHarmony配置网络

方法一：通过命令行配置（临时）

ifconfig eth0 192.168.10.100 netmask 255.255.255.0
route add default gw 192.168.100.1

方法二：写配置文件

对/foundation/communication/netmanager_ext/services/ethernetmanager/config/ethernet_interfaces.json文件进行IP配置，重新编译烧录后即可。
#cat /system/etc/communication/netmanager_ext/ethernet_interfaces.json
{
  "config_ethernet_interfaces":[
    {
      "iface":"eth0",
      "caps":[
      ],
      "ip":"192.168.10.120",
      "gateway":"192.168.10.255",
      "dns":"",
      "netmask":"255.255.255.0",
      "route":"",
      "routemask":""
    },
    {
      "iface":"",
      "caps":[
      ],
      "ip":"",
      "gateway":"",
      "dns":"",
      "netmask":"",
      "route":"",
      "routemask":""
    }
  ]
}

查看网络信息：

查看ip：
ifconfig -a

查看路由表：
cat /proc/net/fib_trie   

或者通过自己移植busybox，使用ip工具族查看或修改网络
