WoL (Wake on LAN) from various routers

Posted by jpluimers on 2019/02/25

Until recently, I hardly used Wake on LAN, so I never noticed that many routers nowadays can send WoL requests themselves.

A few links:

And a few ones from my previous WoL related posts:

Windows 7..10: disable shutdown/hibernate/sleep/restart from UI

Posted by jpluimers on 2019/02/18

I needed this for the Windows 10 machine of my mentally retarded brother: WoL (wake-on LAN) for his machine always works when it is in sleep or deep sleep mode, not every now and then fails when fully powered off.

After it is disabled in the UI, you can still perform it with [WayBackshutdown.exe, so I added these shortcuts first:

Disabling the Shutdown related actions in the UI consists of two steps:

  1. Removing it from the logon screen using the registry
  2. Removing it from the user using gpedit.msc (which is wrapped in mmc.exe)

I will try to get the registry changes for the second using [WayBackRegFromApp – Generate RegEdit .reg file from Registry changes made by application (thanks [WayBack] magicandre1981 for suggesting that at [WayBackwindows – How can I use Process Monitor to detect register changes made by GPEdit modifications? – Super User).
The wrapping mmc.exeis easiest to obtain using Process Explorer, and RegFromApp likely needs to run in elevated mode.

If that fails, I can try Process Monitor as suggested by [WayBack] Tom Wijsman in [WayBackcommand line – Change group policy using windows CMD – Super User.

The reason for the above is that I want to avoid UI based modifications that are hard to script.

Remove Shutdown options from the logon screen

This is just the registry setting below.

It also removes the reboot/hibernate/sleep options from the logon screen, so you need shortcuts for that.

Remove Shutdown for the regular users UI

This can be done using either gpedit.msc (Group Policy Editor) drilling down to the local policies or secpol.msc (the Local Policy Editor):

  1. Drill down to
    1. Local Policies
    2. User Rights Management
  2. Double click Shut down the system
  3. Remove the groups you don’t want the system to shutdown
  4. Press OK to confirm

See the video below how.

I’ve removed the group Users and kept the group Administrators to allow ShutDown.

Administrators now do need to execute the above commands (for instance shutdown.exe /h /f) in with an UAC administrative token enabled!

If you do not want that, add the users that can perform Shutdown commands to a new group, then aadd that group to Shutdown the system.

If you want to perform this system wide for all users, then it’s faster to change the [WayBackWindows Explorer NoClose policy (see also [WayBackGroup Policy Registry Reference).

Raspberry Pi cannot be woken up by WOL, but it can send, and there is Whack-on-LAN

Posted by jpluimers on 2019/01/17

Cool stuff if you want to make your own WOL devices out of spare parts.

From old to new:

They can be woken up by anything sending magic WOL packets, including Raspberry Pi (which cannot be woken up by them, though you could use a Whack-on-LAN for that).

Basically the Raspberry Pi cannot be woken up with WOL because of a few reasons:

  1. The ethernet chip is connected over USB so it cannot pass the WOL result further on.
  2. If it could, there still is no BIOS to process the WOL result.
  3. When it is halted but has power, the CPU isn’t active. The GPU is, but cannot process the WOL.

It can be a WOL server though: [WayBackRaspberry Pi As Wake on LAN Server: 5 Steps (with Pictures)

Mac/PC: sending Wake-on-LAN (WOL) packets

Posted by jpluimers on 2014/07/25

I’ve succesfully woken up these machines:

  • HP XW6600 running ESXi 5.1
  • ThinkPad W701U running Windows 7

I still need to try to wake up a Mac Mini Server running OS X 10.6 (Snow Leopard).

MacBook Air on 10.7 (Lion) and Retina on 10.8 (Mountain Lion) won’t work as they are WiFi only, and WOL does not work over WiFi.

On 10.7 and up it might not work on a Mac Mini Server either, as Apple Introduced Dark Wake.

I used these tools to send WOL packets: Read the rest of this entry »

Some Mikrotik and RouterOS Links to get it running on ESXi for experimental purposes.

Posted by jpluimers on 2014/03/27

RouterOS runs on many kinds of hardware. Of course on the MikroTik hardware itself (which always comes with a license), but also on x86 hardware, even virtualized systems.

In that respect, it looks a bit like pfSense, or Endian, but on steroids and closed source.

Here are some links focused on MikroTik  on ESXi (which is great for experimental purposes):
