You can notice in the example above we launched ethtool with the -s option. How can we do this? All we have to do is to use the ethtool utility and run the following command: $ sudo ethtool -s ens5f5 wol g Once we established the Wake On Lan feature if supported by our network card, we can proceed to enable it. In this case we can see that it is currently disabled (“d”). The current status of the Wake On Lan feature, instead, is reported under the “Wake-on” key. The value associated with the “Supports Wake-on” key, reports what types of Wake-on method are supported: LetterĮnable SecureOn(tm) password for MagicPacket(tm) Here the letter resembles the feature status. The relevant line of the output we want to take a look at in our case, is Supports Wake-on: pg and Wake-on: d. Link partner advertised FEC modes: Not reported Link partner advertised auto-negotiation: Yes Link partner advertised pause frame use: Symmetric Receive-only Link partner advertised link modes: 10baseT/Half 10baseT/Full Supported link modes: 10baseT/Half 10baseT/Full The command returns the following output: Settings for ens5f5: In my case the name assigned to the ethernet interface is ens5f5, so I run: $ sudo ethtool ens5f5 We invoke it with administrative privileges and without any specific option, just passing the NIC name as argument. All we have to do is to use the ethtool utility. This is actually a really simple to task. Inside the firmware interface, the feature, if supported, is typically listed under the “advanced” section (search something like “PCI Device Power On”).Īfter we enabled WOL in our machine firmware, we need to make sure that our network interface card actually supports it. ![]() To do the latter, we must enter the firmware settings interface when the machine starts (this is typically achieved by pressing a key such as F2 just after turning power on). If we want to use Wake On Lan, the very first thing we have to do is to make sure the option is supported by the network interface we want to use to wake up our machine by the machine BIOS or UEFI firmware. $ – requires given linux-commands to be executed as a regular non-privileged userĬheck if the Wake On Lan feature is supported # – requires given linux-commands to be executed with root privileges either directly as a root user or by use of sudo command Requirements, Conventions or Software Version Used ![]() You can also confirm this by running ping -c3 & arp -a and compare the MAC address just to be sure.Software requirements and conventions used Software Requirements and Linux Command Line Conventions Category Since my development box is a Mac, I did brew install wakeonlan and setup a ZSH alias for wakeonlan where the MAC address is that of your network card it will be the same MAC address as the one shown earlier via ifconfig.
