查看eth0

root@android:/ # ifconfig eth0
ifconfig eth0
eth0: ip 192.168.0.180 mask 255.255.255.0 flags [up broadcast running multicast]

查看dns

root@android:/ # getprop net.eth0.dns1
getprop net.eth0.dns1
8.8.8.8

root@android:/ # getprop net.eth0.dns2
getprop net.eth0.dns2
8.8.4.4

设置ip

root@android:/ # ifconfig eth0 192.168.0.173 netmask 255.255.255.0
ifconfig eth0 192.168.0.173 netmask 255.255.255.0

root@android:/ # ifconfig eth0
ifconfig eth0
eth0: ip 192.168.0.173 mask 255.255.255.0 flags [up broadcast running multicast]

设置网关Gateway

root@android:/ # route add default gw 192.168.0.1 dev eth0
route add default gw 192.168.0.1 dev eth0

添加dns

root@android:/ # setprop net.eth0.dns1 8.8.8.8
setprop net.eth0.dns1 8.8.8.8

root@android:/ # setprop net.eth0.dns2 8.8.4.4
setprop net.eth0.dns2 8.8.4.4
