![]() ![]() You can check if WOL is enabled using the ethtool command from the ethtool package: Alternatively you can activate it manually. You can use the integrated WOL functionality of systemd networkd, NetworkManager or ifupdown. If it is not activated, then you need to enable automatic activation. If it is activated, then you can power down your system, and then use another system to wake it. Shuttle XPC SK41G: Power Management Setup -> IRQ/Event Activity Detect -> PowerOn by PCI Card or Modem Ring ResumeĪfter activating WOL in hardware and firmware, it must also be activated in software.įirst check if WOL functionality is already activated. If you do not have that option, there may be another power management or network option that enables WOL. In the UEFI/BIOS boot firmware settings under power management or network you may have a clear, intuitive option labelled "Wake On LAN". 3Com's -NM (non managed) cards do not support WOL while their -M (managed) cards do.Some motherboards support both and only provide the header for backwards compatibility with network cards that don't support the PCI pin.Older motherboards use a WOL three pin connector between your network card and your main board.Newer motherboards use a WOL pin on the PCI bus, negating the need for the cable.Motherboards with onboard NICs usually support WOL without the need for any pins/cables.įor motherboards without onboard NICs there are two main systems: A filename alongside the sol binary (i.e., in the same folder) and named sol.Your first step towards booting your computer from over the network is to make sure your network card and motherboard support some type of Wake On LAN (WOL) feature.(linux only) A filename under /etc/sleep-on-lan.json (if available on disk).(linux only) A filename under /etc/sol.json (if available on disk).The filename manually configured inside the command line with the -config parameter (if available on disk).Order of priority for configuration filenames are : ConfigurationĪn optional configuration file may be used. You can then easily send any computer running Sleep-On-LAN with an HTTP request, with CURL or anything else : curl, for example.Īll other registered custom commands (per configuration) can be triggered in the same way. (all available endpoints are displayed in the logs of the process when it starts) will output the local state of a remoter server for which IP is provided will output the local state of that server, in order to remotely knows if the server is alive or not sends a wake-on-lan magic packet on the network to the provided mac address remotely sleep this computer through this URL If this HTTP listener is activated, the Sleep-On-Lan process then exposes a few REST services, for example : // index page, just shows local IP / mac Wakeonlan 35:78:7a:87:d9:c4 192.168.255.255 // reversed mac address, will trigger the UDP listener of the sleep-on-lan process and will thus remotely sleep the computer Provided you are using a wake-on-lan script like this one : wake-on-lan python script (available as a debian package for example), you may use : wakeonlan c4:d9:87:7a:78:35 192.168.255.255 // regular mac address, will wake an asleep computer ![]() Thus, the same wake-on-lan tools may be used for both wake and sleep operations (python wake-on-lan script, OpenHab WoL plugin, Android applications, and so on). Just send a regular wake-on-lan command but with a reversed MAC address. Grab the latest windows + linux release or snapshot : Sleep through UDP Written in go, the code shoud run on linux and windows platforms. Executed commands are fully customizable. Additionnaly, it can also be triggered through a REST endpoint (with something like curl). that will listen the same Wake-On-LAN port and send the computer in sleep mode when the reversed MAC address received matches a local address. ![]() Technically, you have to run a little daemon (the sleep-on-lan program on your computeri, server, NAS. It works with the exact same magic packet than for Wake-On-LAN, the only difference is that the MAC address has to be written in reverse order. This project allows a windows or linux box to be put into sleep from any other device. ![]() At this time, there is not standard to make the opposite and send a computer in sleep mode. Wake-on-LAN is a standard low-level protocol implemented in various hardware. ![]()
