3)加载启动脚本命令：sudo /bin/launchctl load -w /System/Library/LaunchDaemons/bootps.plist

4)去除启动脚本命令：sudo /bin/launchctl unload -w /System/Library/LaunchDaemons/bootps.plist

设置bootpd的运行方式

1)bootpd有两个配置文件，一个是bootps.plist用于指导dhcp和bootp服务的工作方式，另一个是bootptab，用于设置地址池。(注意，此处的bootps.plist与上一个步骤的plist文件同名，但作用完全不同，前者的目的是设置开机启动bootpd程序，本文件的目地是指导bootpd程序的运行方式)

2)bootps.plist的路径：/etc/bootps.plist

3)bootps.plist配置文件内容：

Subnets

allocate

allow

5)手动启动bootpd的命令：bootpd -Ddv，D表示要启动DHCP模式，d表示前台运行并把调试信息重定向到标准输出，v表示输出更加全面的调试信息。

6)使用苹果系统自带的“控制台”工具程序可以查看bootpd的运行日志。

7)bootpd的日志文件输出到/var/log/system.log文件中。

如果输出以下调试信息，恭喜你，这说明bootpd的启动是没有问题的：

Jan  4 00:05:16 bogon bootpd[3185]: server starting

Jan  4 00:05:16 bogon bootpd[3185]: re-reading /etc/bootptab

Jan  4 00:05:16 bogon bootpd[3185]: Loaded 16 entries from bootptab (0 bad)

Jan  4 00:05:16 bogon bootpd[3185]: server name bogon

Jan  4 00:05:16 bogon bootpd[3185]: interface en0: ip 192.168.1.2 mask 255.255.255.0

常见错误信息：

1.bootpd[1091]: bind call failed: Permission denied

2.bootpd[1290]: bind call failed: Address already in use，说明地址已经被绑定，很可能有bootpd的另一个实例在运行。
