It might be as simple as the wrong file protection mask on the file. ACPI S3 suspend) while the wireless NIC remains active and does varying things for the host, e.g. ![]() On the other hand Linux WoW documentation clearly says: Wake on Wireless is a feature to allow the system to go into a low-power state (e.g. ![]() Regarding your specific question, how is it "not working"? Is "g" not set after the systemd command? If so put in something like:Īt various points in the script and see where it goes wrong, or if it is even executing at all. On one hand tutorials, like on HowToGeek or LifeWire, make it sound like suspend is not necessary. I wouldn't do this on a server, but on a desktop turning off the power strip at various times during the shutdown can sometimes reveal where that might be happening, when the power is yanked before that critical point the system will respond to WOL, and after it won't. So ironically a power failure which is gracefully handled (UPS detects, controlled shutdown) may leave the system unresponsive to a WOL packet. That said, it can be quite bothersome for people who want their servers to wake and return to operation. Hello forum Although I am a complete n00b when it comes to Linux and OMV, I successfully installed OMV 5.x on (top) of my Debian 10.7 installation with some random hardware & a Atlantic AQC-107 10GBE NIC. The other WOL problem one often encounters is that while ethtool may have been used to set the network interface to "g", somewhere during the shutdown something else will turn that off again. 2 Answers Sorted by: 2 The Wake-on-LAN feature is a hardware setting rather than something the OS controls, so it technically makes sense that the machine remains suspended when receiving the magic packet. However, in the case of most desktops that setting will not be sufficient in that scenario. That will in the case of most servers make the machine respond to WOL packets following a power failure (without UPS/nice shutdown) if it is not set to automatically start when it sees power. Add this line last in the file: hass ALL=NOPASSWD:/usr/sbin/pm-suspend, where you replace hass with the name of your user on the target, if different, and /usr/sbin/pm-suspend with the command of your choice, if different.Does the system in question have an option in its firmware that enables WOL? If so, be sure that it is turned on. On the target, using an account with sudo access (typically your main account), sudo visudo.On my system, this is /usr/sbin/pm-suspend. First, get the full path: which pm-suspend. The basic principle of Wake-on-LAN is to setup your computer's network interface to react to specific incoming packets by powering up or resuming the machine, allowing you to suspend or power down the machine, and turn it up or wake it up remotely. Here is it pm-suspend, use poweroff to turn off the computer. On the target, we need to let the hass user execute the program needed to suspend/shut down the target computer.On the server, verify that you can reach your target machine without password by ssh TARGET.Enter the password you created in step 3. On the server, transfer your public SSH key by ssh-copy-id where TARGET is your target machine’s name or IP address.To put a Linux machine in sleep state, a SSH connection to the remote PC can be made for example by executing pm-suspend command (Install via sudo apt install pm-utils ), reference Ubuntu pm-action documentation. There is no shutdown/suspend functionality. If you do, you can leave out in the SSH commands below. Wake-On-Lan (WOL) can only wake a PC from suspend or power-off state. It’s recommended using the same user name as on the server. Just press enter on all questions except password. ![]() On the target, create a new account that Home Assistant can ssh into: sudo adduser hass. ![]() On the server, create SSH keys by running ssh-keygen.On the server, log in as the user account Home Assistant is running under.What am I doing wrong How can I get suspend to work correctly again, and then get it to wake on ethernet I need it for a dvr. There doesnt seem to be anything else on point for ethernet waking. I have an Award bios, it has an option for 'wake on PME event' which is enabled. Suggested recipe for letting the turn_off script suspend a Linux computer (the target)įrom Home Assistant running on another Linux computer (the server). It suspends for about 2 seconds, then wakes itself back up. Here are some real-life examples of how to use the turn_off variable. House of Representatives voted on Wednesday to approve a bipartisan bill to suspend the governments 31.
