手机网络配置

技术点 ： 操作网络配置命令 ifconfig

busybox ifconfig
lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

inet6 addr: ::1/128 Scope:Host

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:681 errors:0 dropped:0 overruns:0 frame:0

TX packets:681 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:66005 (64.4 KiB) TX bytes:66005 (64.4 KiB)

rndis0 Link encap:Ethernet HWaddr 6A:8B:73:98:30:84

inet addr:192.168.42.129 Bcast:192.168.42.255 Mask:255.255.255.0

inet6 addr: fe80::688b:73ff:fe98:3084/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:542 errors:0 dropped:0 overruns:0 frame:0

TX packets:7 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:147939 (144.4 KiB) TX bytes:802 (802.0 B)

技术点 ： 枚举网络接口

单独获取网络接口列表

busybox ifconfig | busybox grep '^[a-z0-9]' | busybox awk '{ print $1 }'

结果示例

lo

rndis0

技术点 ： 获取具体网络接口数据

busybox ifconfig rndis0

rndis0 Link encap:Ethernet HWaddr 6A:8B:73:98:30:84

inet addr:192.168.42.129 Bcast:192.168.42.255 Mask:255.255.255.0

inet6 addr: fe80::688b:73ff:fe98:3084/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:542 errors:0 dropped:0 overruns:0 frame:0

TX packets:7 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:147939 (144.4 KiB) TX bytes:802 (802.0 B)

这里我只需要IPv4的地址信息
