二:DHCP服务器端:(编译器)
1. 修改Makefile: 添加:     CROSS_COMPILE=arm-linux-

2. #make , 把生成的dhcpd文件下载到板子上.
make LDFLAGS="-static"
我编译时提示有个C文件出错,是因为文件中switch case 少了个break。
使用/usr/local/arm/2.95.3/bin/arm-linux-strip处理一下,
3. #cp samples/udhcpd.conf    /etc/                #copy udhcp/samples下的文件到目标板子的 /etc目录
4. # vi /etc/udhcpd.conf: 修改如下:
3 # The start and end of the IP lease block
4
5 start       192.168.1.20    #default: 192.168.0.20   为winXP的ip地址范围
6 end        192.168.1.25    #default: 192.168.0.254

9 # The interface that udhcpd will use
10
11 interface   wlan0       #default: eth 0#目标板子上的无线网卡wlan0 ,按照实际情况改写如ra0等
85 #Examles
86 opt dns 222.201.130.30 222.201.130.33   #dns服务器
87 option subnet 255.255.255.0
88 opt router 192.168.1.10                       #wlan的 ip地址,做为网关地址
89 #opt    wins    192.168.10.10              #注释掉
90 option dns 192.168.1.10 # appened to above DNS servers for a total of 3
91 option domain local
92 option lease   864000      # 10 days of seconds
5# ./dhcpd //运行dhcpd服务器
到此DHCP服务器运行成功。

//compile dhcpd
$ cd ltib/
$ ./ltib -c

Package list  --->
 [*] dhcp                                                     
   [*]   Include DHCP server                            
   [*]   Include DHCP client support
