Supports Wake On Pumbg

After enabling the Wake on LAN in the BIOS the operating system must be informed to enable it before the shutdown otherwise the machine will not turn on even if everything else is done properly. To check if the network card supports the Wake On LAN then the following command can be used. Supports Wake-on: pumbg Wake-on: g ubuntu@tegra-ubuntu:$ Then I putting the TK1 into LP1. Cd /sys/power echo lp1 suspend/mode echo mem state I try to send the magic packet from another machine using wakeonlan, but the TK1 doesn’t seem to wake up. $ sudo ethtool enp2s0 grep Wake Supports Wake-on: pumbg Wake-on: g $ sudo ethtool -i enp2s0 grep bus bus-info: 0000:02:00.0 $ cat /proc/acpi/wakeup grep 0000:02:00.0 PXSX S4.enabled pci:0000:02:00.0 $ lspci grep Ethernet 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Today, we continue our series on readying the homelab for unattended access. Previously, we set up a Raspberry Pi to allow us to remote into our network via a reverse SSH tunnel. That’s useful by itself, especially as a backup if our normal route of access (VPN) is down, but we can also use that same reverse SSH tunnel to do some other incredibly useful things such as waking up other devices on the network with wake-on-LAN (WOL). Today’s tutorial will focus on precisely that: enabling our servers to be woken up on LAN, and configuring our RPi sleeper cell to wake those servers up. Let’s begin!Enable Server for Wake-On-LAN (WOL):
1. On your server, install ethtool:
ethtool allows us to verify that our NIC can support wake-on-lan. It is also used to enable wake-on-LAN on Ubuntu.
2. Find the name of the network adapter you are currently using with the following command:
If you don’t already have ifconfig, you can install it with:
If you need help figuring out which network adapter you are currently using, look for the one with an IP address assigned. You can also look at which network adapter has had traffic go through it (the RX and TX packets line will have non-blank values):
In my case, eth0 is the network adapter in use, and chances are it probably is for you too. If you need help with this, feel free to ask me in the comments/forum.
3. While you’re here, record the address next to ether (highlighted above). That’s your MAC address and that’s how we will ultimately address the server when we are ready to wake it up.
4. Check to see if wake-on-LAN is available on your NIC with ethtool:
In my case that command would be:
If WOL is available on your card, you should see a line that appears as so:
We really only care to see that this line contains a ’g’, indicating a that it will accept a ’magic packet’ (the mechanism by which wake-on-LAN works).
N.B.: If you don’t see it, all hope is not lost, you may just need to enable ’Wake-On-LAN’ in the BIOS. This varies from motherboard to motherboard but almost all have this setting so look for it.
5. Enable the system for Wake-On-LAN:
Don’t forget to replace eth0 with the adapter you’re using if you have a different one.
6. Create the script to insure that WOL is always enabled:
Now, there’s an unpleasant little ’feature’ in OS’s where the above setting gets reset after every reboot.
If you’re using unRAID, this easily handled with the User Scripts plugin. Just create a user script with the following content and set it to run ’At startup of array’ (make sure you have the array set to always start):
If you’re using Ubuntu, we’ll need to create a system service:
In this add the following:
Again, don’t forget to replace eth0 with whatever network adapter you’re using.
Enable the service:
That’s it for setting everything up on the server side. Now, let’s set everything up on our RPi (or whatever other device you have the reverse SSH tunnel set up on).Install Etherwake on RPi:
7. Super easy job here. Just install etherwake on the RPi with:
That’s all!Test Everything Out:
8. Shutdown your server so we can test waking it up.
9. SSH (reverse SSH if working remotely) into your RPi.
10. Just like we did in Step 2 above, identify the network device in use on your RPi.
This is where A LOT of people trip up and why they fail to get wake-on-LAN/etherwake working. By default, etherwake attempts to send out the WOL magic packet on eth0 of the device it’s being run on. If eth0 isn’t in use, you’ll get the following error message:
11. Send the WOL magic packet with the following command using the MAC address you found in Step 2/3 above and the RPi network device you found in step 10 above:
Example:
At this point, you should hear your server kick on and boot up!

We currently have a need for moderators so if you can help out it would be much appreciated!I have two systems. One is my HTPC and the other is my notebook (both running slackware as usual). Both system are connected via my home router. My HTPC is connected directly via lan cable to my home router and my notebook is connected to my home router via wireless lan. In my case I want to wake up my HTPC from my notebook. To check if WOL is supported use the tool ethtool:
notebook# ethtool eth0... Supports Wake-on: pumbg Wake-on: g...htpc# ethtool eth0... Supports Wake-on: g Wake-on: g...
Each letter stands for a specific mode but in most cases the g mode (Magic Packet) should be ok. In my case my HTPC only supports g while my notebook supports the modes p, u, m, b and g. I only use the g mode. If youe need to change the WOL mode then use ethtool again:
# ethtool -s eth0 wol p
The above command will set the WOL mode to p. If you recheck it then the mode should be set to p (if it is supported):
# ethtool eth0... Supports Wake-on: pumbg Wake-on: p...
The next thing you need to know is the mac address of your system you want to wake up. You can get mac address easily with ifconfig:
# ifconfig eth0... ether 00:11:22:33:44:55 txqueuelen 1000 (Ethernet)...
The string 00:11:22:33:44:55 represents your mac address.
Before you can wake up your system you need a WOL capable tool. One is wol which I like to use. Depending on your distribution you can download and install it directly. With Slackware the source has to be compiled first. Before you can compile anything you need the source:
# cd /usr/src# wget -c ’http://downloads.sourceforge.net/project/wake-on-lan/wol/0.7.1/wol-0.7.1.tar.gz’
Then extract the source package and change into the new created directory:
# tar xf wol-0.7.1.tar.gz# cd wol-0.7.1
Run the configure script (no changes are needed for 32/64bit system eg. libdir):
# ./configure --prefix=/usr...wol 0.7.1 configuration: prefix: /usr exec_prefix: ${prefix} bindir: ${exec_prefix}/bin libdir: ${exec_prefix}/lib datadir: ${prefix}/share mandir: ${prefix}/man infodir: ${prefix}/info ether_hostton support: yes generate wol manpage: yes EXTRA_LIBS: ANSI emulation: noProxmox Enable Wake On Lan
Run make to compile the source and make install to install the compiled binaries:
# make && make install
Then check that the wol tool is available:
# which wol/usr/bin/wol
Executing wol is a very simple task. Just type wol followed by the mac address to wake up the desired systems (of course make sure that the system that you want to wake up is turned off):Supports Wake-on D
# wol 00:11:22:33:44:55Waking up 00:11:22:33:44:55...
This works when I wake up my HTPC from my notebook over wireless lan. And there is no difference if my HTPC is turned off or in suspend to ram/disk mode.Supports Wake On Lan Pumbg
