我是靠谱客的博主粗心百褶裙，最近开发中收集的这篇文章主要介绍linux wake on lan功能通过ethtool配置，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

ethtool工具中的wol功能一直很迷惑。今天看了代码将其帮助中下面的参数说明下，如果有不懂wake on lan的请自己到

intel官网查下。

p|u|m|b|a|g|s|d

        if (wolopts & WAKE_PHY)//物理接口
            *p++ = 'p';
        if (wolopts & WAKE_UCAST)//单播
            *p++ = 'u';
        if (wolopts & WAKE_MCAST)//多播
            *p++ = 'm';
        if (wolopts & WAKE_BCAST)//广播
            *p++ = 'b';
        if (wolopts & WAKE_ARP)//arp包
            *p++ = 'a';
        if (wolopts & WAKE_MAGIC)//magic 包
            *p++ = 'g';
        if (wolopts & WAKE_MAGICSECURE)//magic 加密包
            *p++ = 's';

d很明显了是关闭。
