Finally, send the magic packet □ If you’re in Gnome, open the Settings app, select the Network tab, and click the gear by your wired network device. The MAC address is a unique identifier that is used by Wake-on-LAN client applications to send the “magic packet” that will wake up your workstation. Verify this all worked by shutting down your computer, turning off the power supply for 10 seconds, then restarting (to make sure the physical network device isn’t retaining prior settings).Īfter rebooting, sudo ethtool $devicename | grep Wake should show Supports Wake-on: pumbg If you need to tweak anything, you can re-enable the service with sudo systemctl enable -now wol. Description = Enable Wake-on-LAN Documentation = After = network-online.target Type = oneshot ExecStart = /sbin/ethtool -s $deviceName wol g WantedBy = network-online.targetĬheck that there were no errors with sudo systemctl status wol. Replace $deviceName with the name of your device. Run sudo systemctl edit wol.service -full -force and paste this into the editor. SO… It’s gotta be something involving systemd, right?ĬORRECT. NOPE, that file doesn’t reliably exist since NetworkManager times. Good idea, though old man wise neckbeard.Īh, just follow the /etc/network/interfaces instructions on the Ubuntu wiki? That file’s been gone for over a decade on many linux distributions. Simple, just add it to /etc/rc.local, right? If you’ve read to here, you’ve enabled Wake-on-LAN on your hardware… but might have caught the bit about needing to run ethtool -s $devicename wol g after every reboot. Reboot and hit f2/del/f12 to enter BIOS configuration, and poke around–mine was enabled via a Power submenu. If you don’t see it, don’t panic: it may just be disabled in your BIOS. That’s done by running sudo ethtool -s $devicename wol g. If Supports Wake-on: includes g, we’re in business: we just need to set Wake-on: g after every powercycle. You’ll see something like this: Supports Wake-on: pumbg Run sudo ethtool $devicename | grep Wake (replace $devicename with the name of your device). Ignore lo (that’s the localhost LOopback device) and any named docker* or br* devices (those are for docker and bridge networking). Run ip link to get the name of your network device. Install ethtool (via sudo apt install ethtool) Unfortunately, it typically requires a bit of tweaking.įollowing the steps on the Ubuntu wiki, : The answer is yes: Wake-on-LAN is a thing. Is it possible to remotely resume power on my workstation? The issue is if I’m remote, and I need access to my workstation. Remote wakeups: how to enable Wake-on-LAN □ The system wakes up and is available in a couple seconds, and most things are right where I left them–except for Firefox, which regularly crashes, but all my prior tabs restore automatically when I re-launch Firefox. So, I come back to my workstation after my morning coffee, and it springs back to life when I hit a key on my USB keyboard. Power drops to 2 watts (!!) when suspended to RAM. The latest version of Ubuntu (and my current motherboard) support “ suspend toĬonfiguration can be done via the built-in Settings app, which is simple and I can’t do much about the power consumption while I’m using it–but that idleĬonsumption certainly could be reduced. ![]() It’s nice and speedy, but consumes 500+ watts when busy, and 200 watts ![]() ![]() PhotoStructure is (mostly) developed on an AMD Ryzen 9 Photo by Bruno Set up Wake-on-LAN on systemd MaOR: How to Help Save the Earth, and save a couple bucks on your electric bill □
