我正在尝试使局域网唤醒功能与我直接连接的一台设备一起使用。我已经在 BIOS 中启用了该功能,并多次尝试使用wakeonlan
它。
因为以太网上只有两个设备,而第二个设备已关闭,所以我怀疑我的计算机不会尝试在线路上发送数据包。起初,我发现我的网络接口已关闭,因此我将其启动ip link set dev enp0s25 up
。然而这并没有帮助。
我用wireshark检查了一下,接口上没有发送任何数据包。当我尝试通过以太网 ping 或 ARPing 时,Wireshark 也看不到。然而,Wireshark 可以与电缆另一端已打开的计算机完美配合。
那么,我如何确保我的计算机尝试通过线路发送 WoL 数据包,如果没有,我该如何使其工作?
有关发送器设备的一些附加信息:
