/******************************************************************** * busybox filesystem udhcpc 原理 * 声明： * 本文主要是记录busybox中的如何运用udhcpc获取IP，参考文章里写的 * 很详细，不再累赘。 * * 2016-1-23 深圳 南山平山村 曾剑锋 *******************************************************************/ 一、参考文章： BusyBox 應用 – udhcpc http://felix-lin.com/linux/busybox-%E6%87%89%E7%94%A8-udhcpc/ 二、应用： 1. 拷贝udhcpc脚本： cp busybox-1.24.1/examples/udhcp/simple.script <filesystem root>/usr/share/udhcpc/default.script 2. 运行： udhcpc -b -S -p /var/run/udhcpc.pid 三、效果如下： udevd version 126 started zengjf login: root login[1423]: root login on 'ttymxc0' udhcpc (v1.24.1) started Setting IP address 0.0.0.0 on eth0 eth0: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=1:01, irq=-1) Sending discover...
