网络唤醒主要需要主板支持， 在BIOS里设置Wake on lan[Enable]
网络唤醒的包很容易构建，但是在网管服务器上始终不能工作，刚开始以为是程序的问题， 后来发现Ubuntu里有一个wakeonlan的perl脚本，在ubuntu上工作正常，而在网关上却不能正常工作 最后发现是好像是双网卡的问题，给wakeonlan加上一个-i参数指定内网的ip，启动成功！ sudo apt-get install wakeonlan #实际就是在/usr/bin下生成一个名为wakeonlan的perl脚本，拷贝到Fedora等也可以用。 wakeonlan -i 192.201.0.255 00:1c:25:db:bd:46
贴上一个c语言的网络唤醒代码 #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #define oops(msg) {perror(msg); exit(1);}
