WOL持久化设置(保证重新开机仍然开启网卡的WOL功能)

创建一个WOL开机进程

sudo nano /etc/systemd/system/wol.service 

写入内容

[Unit] Description=Configure Wake On LAN  [Service] Type=oneshot ExecStart=/sbin/ethtool -s INTERFACE wol g  [Install] WantedBy=basic.target 

使systemd知道新的WOL脚本

sudo systemctl daemon-reload 

使能WOL脚本

sudo systemctl enable wol.service 

启用WOL脚本

sudo systemctl start wol.service
