ethtool interface grep Wake-on ethtool eth0 grep Wake-on Supports Wake-on: pumbag Wake-on: d. So while industry-wide Wake-on-LAN is a network device feature based on a magic packet (that requires no OS interaction), Mac's magic "wake-on-LAN and also still respond to pings" is because they haven't actually put the whole OS to sleep and/or have a separate network stack still running in sleep mode. ethtools will help you, but the hardware must allow your needs. My assumption is this is because Apple controls the hardware and software stack. And after I've logged out, 15 minutes later it will go to sleep again. Don’t worry too much about that, as our next task will be to enable it. The second line shows whether Wake-On-LAN is enabled. There might be other letters along with the g. This 2nd property ends up being really nice: it automatically goes to sleep and saves power when not in use and doesn't require any extra thought to power on when I want to ssh into it. The first line tells you whether your PC supports Wake-On-LAN. It will wake up automatically upon incoming ssh connection, no Wake-on-LAN required. You may add customized environment variables following the instruction. run make deploy-test to run without detach mode. or just run make deploy (alias of the docker run command above). It still responds to ping on the network. docker volume create wol docker run -d -networkhost -restartunless-stopped -name wol-web -v wol:/wol-server/data huakunshen/wol:latest. I have noticed that it goes to sleep and has two distinct properties separate from any Linux machine I have while asleep: On boot, Ubuntu should read all the files in /etc/netplan/*.yaml and apply their configs.I have been using Wake-on-LAN successfully for many years now for a number of my Linux devices. Once youre inside the BIOS, look for the Wake On LAN setting. Is there a way to run this command without sudo I need to do so in order to run the command in a php script. Press the correct key at boot (try ESC, DEL, F2, or F8), and your computer should enter the BIOS. However, It only works if I use sudo: sudo wakeonlan xx:xx:xx:xx:xx:xx When I dont use sudo the output says the magic packet has sent, but the server never wakes up. Related articles Wakeup triggers Hardware settings Wake-On-Lan only works if you fulfil the following preconditions: The target computer's motherboard and Network Interface Controller has to support Wake-on-LAN. Then, I had to open the Ubuntu Network Settings UI to switch to the newly created ethernet interface netplan-eth-no-wakeonlan. 1 Im trying to use wakeonlan to send a magic packet. View history Wake-on-LAN (WoL) is a feature to switch on a computer via the network. This tutorial says that a reboot should be enough (and deleting the yaml file, I assume) NOTE: Apparently, it's a known bug that netplan try fails to revert the configs. On RHEL, this is usually done from /etc/init.d. It needs to be configured every time the machine boots. The Wake-on-LAN setting does not persist. In the example above, Wake-on-LAN is currently disabled (d). To test this configuration, I ran sudo netplan try, which applies the configurations for some minutes before reverting. It should list one or more letters, including g (WoL using Magic Packet). Wakeonlan: false # To enable, set to true I created this Netplan config YAML (you need sudo access to create a file in that dir):.Canonical also provided some nice documentation on how to use Netplan:įor my specific case, I wanted to disable Wake on Lan, but this boils down to just setting a boolean to true/ false. For me, using Netplan configurations worked (both for enabling and disabling WOL) since I am using Ubuntu.Ĭheck this similar question about how to enable it.
