Support for Wake On LAN

Would like to request the following changes (could make it more easy to support WOL):
/etc/config.d/wol:
# Comment out the following line to support Wake On LAN
WOL_ARGS="-i"
/etc/rc.shutdown (or wherever there's a reference to 'halt -i' or similar):
. /etc/conf.d/wol
/sbin/poweroff -d -f -h $WOL_ARGS
/sbin/reboot -d -f $WOL_ARGS
[Edit]
/etc/rc.d/network:
. /etc/conf.d/wol
if [ -n $WOL_ARGS ]; then
/sbin/ifconfig ${1} down >/dev/null 2>&1
fi
Thoughts?
Thanks

You should submit a feature request for this on the bugtracker. Here in the forum, there is no guarantee that the right devs, or any devs, will see it.

Supports GT780 wake-on-lan and wake-on-usb?

Does the GT780 support 'Wake-on-lan' and 'wake-on-usb'? Especially the last one is important for me as I will use the laptop 99% with closed lid. So I would like to be able to wake it just by pressing a key on the keyboard.
Thanks!!

Have a look and see what settings there are in the 'Power Management' section of BIOS setup.
I don't own the computer yet. If the wake-on-lan and wake-on-usb works, I'm gonna buy the computer. But: I did find the manual on the internet (I did my research before posting), but it didn't say anything on wake-on-lan en wake-on-usb. So, I hope somebody from MSI or somebody that owns the computer can answer this?

Does ZCM use Magic Packets for Wake On Lan?

Hello,
not sure if this is the correct forum...
can someone please refer me to the technical documentation of wake on lan from ZCM or tell me how Zenworks has internally implemented Wakeonlan - is it simple Magic Packets or is there some other mechanism?
thx,
hugo

I also remembered there is this TID that has some good info.

WRT160Nv2 wake on lan

Can linksys please incorporate support for wake on lan please?

Hallo Forumreaders,
WOL (Wake On Lan) works only through a router when it is capable to forward to broadcast LAN-IP-adres.
In my consideration only the good old BEFSR41 is capable to forward to the broadcast adres for example 192.168.1.255 (SM: 255.255.255.0)
Because there is no IP-adres in powerless PC's the "Magic Packet" (which WOL realy is) MUST be send onto your LAN by means of the broadcast-adres.
Other routers are NOT able to sumit a adres like 192.168.1.255 in a subnet of 255.255.255.0 because they are NOT allowed to use any broadcast-adres.(they can get trouble by means of a broadcaststorm!!!)
So do not get rid of that old router you have!!
More info;
The "Magic Packet" contains the MAC-adres of your recipient host and wil trigger the powersupply of that PC.
For Internet WOL, try http://www.dslreports.com/wakeup, submit your IP-adres of your home, your MAC-adres of your PC and klick on "Wake up".
Looking for an application for on a USB-stick, download the small tool; http://www.depicus.com/wake-on-lan/wake-on-lan-gui.aspx
Hope I helped,

Wake on Lan works on my MacBook Pro, not on my iMac...

Hello everyone, with all these threads about the problem, I wanted to start a new one to make it clear, with all information you may need in order to help me out.
I've got a MacBook Pro '15 and an iMac 21.5', both are running (clean install) OS X Mountain Lion 10.8.2, both are up to date with the latest updates, both have the same apps, both have the same settings in "system preferences", and of course the same settings in "sharing" options.
My iMac is connected to my 5GHz network from my Time Capsule while my MacBook Pro use the 2.4GHz network.
Before going to bed, I leave both my Macs turned on, after 10min they go to sleep automatically. In the morning I can wake up my MacBook Pro from my iPhone or iPad with a screen sharing app.
The iMac doesn't respond at all. It stays in sleep mode. I can leave my MacBook Pro asleep for a week, it always responds. The iMac responds after a few hours but after 6 or 8 hours it seems to be completely asleep and doesn't respond to anything. If you think it's about the iPhone/iPad's app, when I try to wake the iMac from my MacBook Pro with "Back to my Mac" I have the same results.
I tried to connect my iMac to the 2.4GHz network: same problem.
OF COURSE "WAKE ON LAN" is activated in my system preferences.
I made a reset of the PRAM, the cache and the SMC on my iMac: same problem.
I type sudo periodic daily weekly monthly in the terminal and sudo dscacheutil -flushcache: same problem.
I tried everything I may have found in the forums or on this Support from people having the same issue: same problem.
I even tried to set the iMac with the same sleep mode as my MacBook Pro: same problem.
PLEASE HELP ME!

I understand that, but if your router is not an Apple AirPort Base Station then it introduces an element of uncertainty. Apple has implemented many changes related to wireless networking recently.
You are complicating matters by changing networkoversleep:
networkoversleep - this setting affects how OS X networking presents shared network services during system sleep. This setting is not used by all platforms; changing its value is unsupported.
Solving problems like this requires that you simplify your network environment and eliminate its unknowns. Using third party routers and making unsupported changes runs counter to simplification.
The iMac stays connected to the Time Capsule about 6 hours during sleep. Then it dissapears...
The iMac wakes periodically (every few hours) to inform your router of its network presence for Wake on LAN demands. Try changing your router's DHCP lease period to something longer than a few hours. For a home environment, a few days is more appropriate. This may not solve the problem, but it is better than making unsupported changes to your system.

G710 Wake On Lan

Hi all,
I am trying to figure how to enable Wake on lan on G710 laptop.
It works while in sleep mode but not in hibernate or shut down.
Is this laptop cabaple for Wake On Lan in hibernate and shut down?
Will kindly appreciate any help...
Thanks
Benny
Solved!
Go to Solution.

hi benny_ru,
Welcome to Lenovo Community Forums!
This may not be possible. Since this is not supported in BIOS
When the computer is in Hibernate and/or in shutdown state it need to cross the BIOS to wake up the computer or turn it on.
Sleep will be ok since the LAN card supports it and it is the OS that wakes the system up and not the BIOS.

Wake On Lan Q190?

What's the secret?
Went into Device Manage for my NIC. I have ticked "only allow a magic packet to wake up the computer" on the NIC, and unticked ""allow the computer to turn off this device to save power". Verified "shutdown wake on lan" is enabled.
Disabled the wireless adapter.
I disabled fast start up.
I removed every "wake on lan" allowance in device manager except for human interface/mouse/keyboards and the NIC.
Went into BIOS and made sure the energy saving routing ErP routine is not enabled.
My USB connected wireless Logitech keyboard wakes the computer, but I can't get a magic packet to wake it.
Ideas?

Hi bfb1963,
Welcome to Lenovo Community Forums!
AFAIK Wake on Lan has to be supported by the MOBO and BIOS should have an option to enable / disable Wake on LAN.
If the BIOS does not have an option for Wake on LAN then most probably it is not supported.

E900 Wake on LAN/WAN

Helly community!
I'm fairly new but would like to ask someone for help.
I would like to configure my PC to be able to use wake on LAN/WAN mainly for power issues, so I don't have to have it on all the time to access anything I need. I bought a Linksys Cisco E 900 2 weeks ago. Now I am getting really frustrated since as far as I know I did configure everything needed for it but it does not seem to work nor through WAN or even in LAN.
What I did so far is:
1. In my BIOS I could not find a seperate wake on lan option under power management but I did find a "Power on by pci(e) device which I have enable.
2. I have a built in Realtek Ethernet card on my motherboard. In the setting I:
Shutdown wake on lan - Disable
Wake on magic packet - Enabled
Wake on pattern match - Enabled
Also the option to allow this device to wake up the computer using magic packet is also ticked.
3. I use Windows 7 and have installed and started Simple TCP/IP Services
4. I opened up UDP port 9 in Windows Firewall
5. I have set single port forwarding in the E900 to my reserved IP for both TCP and UDP port on port 9 and just in case port 7.
After all this it is not even working inside my LAN. Also I tried a port scanner and checking for open ports and UDP port 9 doesn't seem to be open. Why is that? Did I configure something wrong in the router?
If someone could help me I would really appreciate it.
Thank You in advance!

Wake on LAN (WoL) is a technology that permits someone to turn ON a computer remotely. The network adapter on the computer listens to network activity and will turn the computer ON once it receives a special data packet called a “Magic Packet” that triggers the boot up. Wake on LAN is also referred to as Remote Wake-up.
For Wake on LAN to work on a computer, it must have the following:
•   a wired connection to an active computer network
•   motherboard
•   network adapter and adapter driver that supports the standard Magic Packet format
•   computer basic input/output system (BIOS) configured for WoL
•   an operating system that supports WoL
•   all routers between the remote location and computer required to WoL must allow IP directed broadcasts and support IPv4

T500 Wake on Lan (wireless) does not work.

Hi,
I set up T500 (Windows 7 Ultimate 64bit) for wake on lan,
1) Enable Bios WOL
2) Enable WOL in power manegement tab of Intel WiFi Link 5300 AGN property in device manager.
But WOL does not work. Sending magic packet from a PC in the same WiFi segment does not wake up sleeped T500.
Are there any setting for WOL in lenovo tools ?
Does anybody use WOL(WiFI) on T500?
Thanks,

Is the T500:
Associated with an access point at the time it is put into standby/sleep mode?
Connected to AC power for the whole time it is in standby/sleep mode (in otherwords the whole time it is in a low power state) when you are attempting to use WoWLAN?
If not, that may be at least part of your problem, as it is a known limitation on WoWLAN operation.
You also need to have the laptop "set up" to the master workstation, and the WLAN configured to handle braodcast wireless frame, but I am presuming you have already done that side of things.
Cheers,
Bill

How to configure Wake On LAN to work through the Internet?

I'm using an iOS app to wake my desktop computer. It works perfectly fine when I'm within my WiFi range. However, when I'm out of my Linksys E3000 access point, it no longer works over the Internet. So, if anyone can point me to documentation that have step by step instruction on how to configure this through the Linksys E3000 access point, I'll be grateful.

Hi ohgosh,
I believe your computer is already configured and has all the requirements for Wake on Lan since it works locally. To do it remotely you need to open the regular port numbers used for WOL like UDP ports 9 and 32767. Your desktop IP address must be set to static because that's what you need to enter on the port forwarding page of your router. You may use this link below for instructions on how to do port forwarding on your router.

Another option is to set up DynDNS on your router. With this, you need to subscribe to DynDNS.com. I found some online links that could help you enable WOL remotely:

3.2 Server Stuck Offline & Wake on LAN issues

Got through installation and getting started guide running 1 VM Server and a separate VM Manager I was able to shutdown the Server from the Manager GUI; however, when trying to restart the Server from the Manager I received an error: OVMAPI_4005E No worker server found to perform operation on: ovmserv1. I was able to restart the Server by pressing the power button and the Manager was able to recognize the Server as on after it booted. The Manager reports the Server as having Wake-on-LAN 'Yes'. I'm using onboard NIC on Supermicro server, BIOS has a wake on modem feature, nothing for wake on LAN or PCI device. I checked the Server with ethtool and it reported Wake-on-Lan was enabled on both eth0 and eth1. There is an optional IPMI card available for the server but my understanding is that IPMI is only needed if trying to wake from a different network, while everything here is on the same LAN and ping-able. Any help will be greatly appreciated.
Last night I added an Openfiler iSCSI SAN with 3 SCSI targets, one for the pool file , one for the repository and an extra one. Setup server pool, pool file and repository in the Manager. Everything seemed great and I was looking forward to importing some appliances the next day and I shutdown for the night. Today I was trying to setup an FTP server and was messing with LDAP on the Openfiler server, unable to get that going I tried to setup an FTP server on my laptop which is also on the LAN. Later when firing everything up, somehow the NIC on the Manager had been disabled and the Manager was booted without network connectivity. After shutting down the Manager, re-enabling it's NIC and booting up again, the network connectivity was good. The problem is the Manager reports the Server as either Offline when the Server is on, or Stopped(Error) when the Server is off. Using the Manager trying to start the Server fails with 'already on' and trying to stop Server fails with 'not running'. I shutdown and rebooted all 3 servers a couple of times in different orders and the problem persists with the Server still stuck in Offline status. Any help will be greatly appreciated.

Hi,
I uninstalled Mozy a long time ago just because it did prevent my iMac i7 to go to sleep.
I don't know if they have fixed the problem since with an update, or if they'll do it but yes for me back then Mozy = no sleep.
Wake on lan should stay unchecked if you don't need it, this is also known to be a frequent cause of sleep issues.
EDIT : sorry... I didn't read properly your message... My problem was the opposite... Sorry again for my mistake...

Automatic Wake On Lan/Sleeping Arch Box?

I have my home (media) server setup that runs Arch and it does multiple things, it's the media server for all the XBMC clients in the house along with being an Apache/MySQL/CouchPotato/SickBeard/SABnzbd server. The thing is that about 50% of the time (usually between 2am and 10am and possibly during the day) it isn't really utilized and is just sitting there idle. Is there a way that I can have it go to sleep and have my router (Linksys e3200 soon to be flashed with DD-WRT or I may build one out of a Raspberry Pi) or something else automatically send a "magic packet" to wake it up whenever something tries to make a connection to it? Or would it just be easier to keep it on 24/7? I'm trying to reduce my electric bill a bit and was looking at getting a 4-bay NAS for this reason (considering the one I was looking at consumes 35w active and my pc probably consumes ~400w) but the thing is they're about $500. So in the long run it would definitely save me money but in the short run it would cost me a hell of a lot more than just leaving the pc on all the time.
Suggestions?

For the first part I don't really know but I imagine it can be really simple, perhaps just running a script with cron?
There's a whole section for Wake on Lan in the wiki of both Arch and DD-WRT:
https://wiki.archlinux.org/index.php/Wake_on_lan
http://www.dd-wrt.com/wiki/index.php/WOL
Again a script would probably do the job using the wol package. If you want to put it to sleep automatically when it's idle for a certain amount of time then checking cpu utilisation is easy:

Wake on LAN using get-cmdevice ?

Is it possible trigger the WoL feature that is used by SCCM to deploy apps and updates using a Powershell command?
I'm thinking of something like:
get-cmdevice -devicename xyz | do-CMWakeOnLAN
We have WoL functioning but sometimes it is useful to be able to wake up a PC without deploying anything.
Any thoughts?
Neil
PS I know there are 3rd party WoL tools but they don't use the information that SCCM has collected about a device

You may not need to leverage ConfigMgr for this.

Wake on lan using Artigo A1000

Hello everyone,
I have an VIA Artigo computer. I loaded Arch Linux on it and I wanted to use wake on lan. I followed the instructions on the wiki page for wake on lan, but it would not work correctly when I tried to wake the computer using wol. It would only work if I had hibernated the computer using the pm-hibernate command. If I tried to wake it after turning the computer off by either using the halt command or shutdown command it would not respond to the magic packets. I tried doing some searches for this problem but I couldn't find anyone using Arch Linux with a similar problem. I broadened the search and found that others had experienced this problem in other distributions using similar hardware. According to them, the problem was that when the computer was being shutdown it was taking network offline, which would prevent the system from recognizing the magic packet being sent. Their advice was to prevent the OS from doing that at shutdown. Unfortunately, their specific solutions didn't seem to apply to Arch Linux, I'm not sure if it has to do with their distros using sysv scripts vs Arch Linux's BSD style scripts or if it was my cluelessness. I was able to get it to work by editing the /etc/rc.d/network file and commenting out the line that reads /sbin/ifconfig ${1} down >/dev/null 2>&1 in the ifdown() function. Doing that has resolved my wake on lan problem, now the system will respond to magic packets sent using the wol command after I have shut it down using the shutdown command. My gut feeling tells me that it might not be the best way to fix this problem, I'm concerned that I might update a package some time in the future and this configuration file may get wiped out. Is that a valid concern? Is there perhaps a better way of fixing this problem?
Please let me know.
Thanks!

Wake on Lan works with Ethernet, not over Wi-Fi.

Hello, after several months of tests I came to this conclusion.
Wake on Lan only works with Ethernet for my iMac. Wake on Lan over Wi-Fi works for a few hours, but if the iMac is asleep for 6 hours or so, it becomes unavailable... On the other hand, with Ethernet it's always available even if it sleeps for an entire week.
My iMac isn't that old (mi-2011), so I guess it should handle Wake on Lan over Wi-Fi. Is it a software issue?
- I've got a MacBook Pro since Snow Leopard 10.6 and now with Mountain Lion it handles Wake on Lan over Wi-Fi without problem.
- I've got my iMac since Lion. Does the iMac only handle Wake on Lan with Ethernet and works differently compared to the MacBook Pro?
I prefer to use Wake on Lan over Wi-Fi because for the tests I've placed my iMac in the living room in order to plug it to the Time Capsule, but the right place for my iMac is in my bedroom.
I tried to change the MTU size as it is described here: http://osxdaily.com/2012/08/02/fix-os-x-mountain-lion-wireless-connection-proble ms/
Note that "Wake on Lan" is checked in my System Preferences, I don't think it's my router's fault, because my Apple TV, AirPort Express, iPhone 5, iPad 2 and my Printer don't disconnect even when they're asleep (I'm talking about my printer and Apple TV in that case).
