Wake on Lan feature

More of a comment then a query but I'm amazed that the WOL is not implemented correctly. Very frustrating that it only works when a system is in sleep mode. If a PC is off it can be woken up, so why Apple chose not to allow this is beyond me.
This means if I need to image some systems I have to go and switch each one on manually. I'd chose to have each systems default boot-device as the network card so if no netboot foud it'd go and boot off the HDD.

Wake-on-LAN is implemented correctly, in that a sleeping Mac can be awakened by a signal across the network. What you want is Boot-on-LAN, and that's never been a feature of Macs (at least not any I can remember, back to the original Mac models) with the exception of the Intel-based Xserves. But you can submit your comment to Apple via their feedback pages:

Using the Wake On LAN feature

I use software that allows me to turn off the computer, and then have it come back on if I "activate". I believe this feature is called WAKE ON LAN. My questions is what do I have to do to the MAC to get it to do this? Is there something in the OS that I have to say "wait for signal, then start up"
Any help with this would be appreciated!
Thanks

You need to plug that Mac into the network(wireless won't work), enable the feature from the Energy Saver pane of System Preferences, and then use a tool on another computer to send it a magic packet.

Wake On Lan Feature - How to enable??

Hi..
I would like to enable WoL feature in certain part of our network. Is there a global command to enable that?. or does it only require 'dot1x control-direction in' interface configuration?..
Also does the WoL Magic packet get forwarded through routers??
Any help appreciated.
Thanks.

Could I just clarify the answer that Rick gave? I fear that it might give the impression that the ip helper-address is on the remote LAN, which it is not.
You should put the ip helper-address on the LAN where you have the management server that is trying to wake up the remote PCs. If the remote PCs are distributed across several remote LANs, you will need one ip helper-address command on the "central" LAN for each and every remote LAN you are trying to get to. You can have as many ip helper-address commands as you need to cover the remote LANs you have.
As Rick says, if you have multiple routers between the server and clients, then the ip helper-address commands only need to be on the LAN that hosts your management server.
What the ip helper-address command does, is to recognise broadcasts on the server LAN, and convert them into unicasts to the address you specify: in my example 192.168.42.255. These unicasts are routed through the network in the normal way until they reach the destination LAN. When they get there, the client LAN's router say "eh-up, this is my IP subnet broadcast address; I had better put a broadcast MAC header on it." But it will only do that if you have configured ip directed-broadcast on the target LAN.
If you think of the way it works, you could even do WoL across the Internet, where you do not have the hand on the intermediate routers.
Is that OK?

Wake on LAN across subnets

Is there a way to get Zenwork's wake-on-lan feature to work across subnets?
I am not a LAN administrator so pardon any ignorance you see in my
question.
Zenwork's wake-on-lan function won't work on our LAN because our switches
are set to not allow forwarding of subnet-oriented broadcasts, which is a
generic requirment for zenworks wake-on-lan function to work. Our security
folks say enabling this on the switches is not an option because it
introduce a security vulnerbility. I find it strange that there wouldn't
be a solution for this by Novell/Zenworks considering that multiple
subnets, switches, and security considerations are usually a component of
all networks which zenworks is specifically targeted for in the first
place.
Thanks

limit the packets comming from either your c1 wks or the zenworks server

Exactly, and this is the best choice. Make "Replication Servers" in each subnet, is very simple. U can use a Windows machine or SuSE, both without installing zenworks. Only registering them as servers satellites. You must install the agent (logically, hehe).

Can't Wake-On-LAN up iBook from Sleep Options

Seasons Greetings!
I can't get my 1.25gHz eMac to wake my 900mHz G3 iBook from sleep to
auto backup overnight via the Wake-On-LAN feature using an Ethernet
connection and Wake 550. I set the Administrator Wake tab in the
Energy Panel and looked up my iBook's Machine Address in the Network
Utility to type into the Machine Address box in Wake 550 but no go. I
even put in the IP and my iBook still sleeps. Any hints?
Thanks!

I'm starting to wnder if the PB has a Wake-On-LAN compatible ethernet card!?
Or if maybe you have something like a Cat-3 cable that doesn't have as many lines as a Cat-5e/Cat-6 cable?
After hours of experimentation WOL, 550, & Nudge all work reliably for waking if you have a WOL Ethernet card, somewhere above a Cat-2 cable, even if the originator is Airport only to an Ethernet Router that the others connect to.
Can't find much info as to which Macs have WOL capable cards except that up to the original iMac they didn't. I'm thinking maybe a G3 Powerbook doesn't since it's on the list of needing a Crossover cable to connect to another on that list...

MSI G70 Dragon Edition 2 and wake on lan

Hi everybody.
Does G70 laptop support wake on lan feature ?
Or how i can get wake on lan feature for this laptop.

Here I reply to myself : I think this will be useful to other people, whatever the motherboard model.
So, I just SUCCESSFULLY have been able to wake up my PC from the LAN
Here are my conclusions :
1- There's nothing in the motherboard documentation that explicitly indicates that it's supported. But it is !
2 - I didn't need to connect the LAN card to the motherboard (didn't need any WOL connection)
3 - I have a patched Windows XP. But its standard drivers for my network card weren't enough. I had to install the updated drivers from the manufacturer (admtek).
4 - With these drivers, I could then access, from Windows devices setup tool, to the network adapter APM properties, and I could "Allow Device to Bring Computer Out of Standby".
5. Inside the BIOS, a few things to setup :
Power Management Features
-> IPCA Function : Enabled
-> Power Management / APM : Enabled
-> Set Wake Up Events ... Wake Up On PME# : Enabled
Actually, this means that there is no explicit need for a "Wake On LAN" configuration. It all goes through PME# (i.e. direct PCI) wakeup events.
6. Then it works :-)
The excellent free tool available at
http://www.depicus.com/wake-on-lan/
does the job at the remote computer side (when fed with the valid MAC and IP addresses).
I'm very pleased... but I wish MSI had somehow indicated that the motherboard is WOL capable !

Wake-over-LAN with WRT54GX2

I'd like to wake up my computer over the internet, so I'm trying to use the Wake-on-LAN feature.
I can get it to work when waking from the local network....but I can't over the internet. I've read that I need to forward the right port to 192.168.1.255, but I can't forward to that address.
Is there anything I can do?

hoping someone can help me here, as I want to accomplish WOL in my workplace. I'm in a building that has a central router that divides the internet into 4 different offices (into jacks in the wall). The central router is a linksys befsr41 that I don't have access to because it belongs to the property manager. The central router's ip address is 192.168.1.1 This router is not wireless, but I need wireless in my office, so I have my wrt54gc in my office to use with my tablet pc. I've gotten my computer to wake up no problem over LAN at home, over WAN at home (from remote location), but when I'm at my office (2 routers chained together) I don't know what I need to do to get it to work consistently. So my questions are: 1. What settings, if any, do i need to change on the central router? Do I need to port forward to the IP of MY router (or my CPU)?? 2. Same question for my router? I've looked all over the net and can't find any info on what to do for WOL in a multiple router environment such as mine. I guess I need to somehow tell that magic packet thingy to go through the central router, then through my router, and recognize my MAC address and ip. I really appreciate help in this matter.

Wake on Lan questions

Hey,
I remember way back when I was using a PC that I could actually boot my computer through the network, using the Wake On Lan feature on the motherboard/bios.
Is this possible to do on a MBP?
I'm not talking about "waking it", as if it was asleep, I'm talking about "wake" as in start/boot up.
If this is even possible, I guess it's limited to Ethernet only and not supported by Wifi.
But would it be possible for the sender of the wake-up package to be on Wifi (from say an iPhone or another MBP connected with wifi).

I found out this is not a problem with iWol, its about configuring the router correct.
Check this out, it helped me solve my problems:

Wake on LAN does not wake computer

Hi,
I'm using ARD 3.2 on OSX 10.5.2 on a dual G5 system. Its IP address is 192.100.1.102, and it is connected using the built-in wired Ethernet jack.
I can't wake my other computer, which is a G4 iMac running OSX 10.4.11. It is also connected to the network using its built-in wired Ethernet connection, with an IP address of 192.100.1.100. I have also disabled the wireless interface in this system. I have verified that under System Settings, the check box "Wake for Ethernet network administrator access" is checked.
Both systems are connected to a D-Link home router like many people have. Nothing exotic. But when I try to Wake the G4 using ARD, under Manage -> Wake, it does not work. The G4 doesn't respond, and eventually ARD times out and gives up.
However, two interesting points:
1. I found a freeware utility called "WakeUp" at http://www.coriolis.ch/en/wakeup and that is always able to wake up the G4.
2. I have found that if I put the G4 to sleep using ARD, I am then able to wake it up using ARD also.
Any help?
Thanks!

Consumer routers/switches such as your D-Link generally do not support the enabling of directed broadcast packets, which are required for use with the wake on LAN feature, so that may be the problem.

Wake on lan with Iphone.

Hi, I installed a wake on lan feature on my MBP from apples homepage and likewise I installed the iWOL app on my iphone. However I cannot get it to work. At home I use Airport express connected wirelessly to the MBP and likewise with the Iphone. Do I have to configure the airport express or something? Or does anyone have a step by step guide on how to set it up?
Thank you very much

its right , router has to be connected to Ethernet port.
ary you trying to wake your Mac on your local network ( meaning when you are conected to your router through wi fi directly ?) that is not to difficult to achieve . little tricky bit is if you want to wake your Mac
from remote location from your iphone , well literality from anywhere . it can be done but not all routers will allow you to do that . but it can be done with right router . plus there's quite a bit needs to be changed in correct router's configuration. but good thing is if you really want that to happen there is a possibility .
for my needs its essential . i use iwol and SleepOver apps. both of them do same thing but first i got iwol
and only could wake my MP locally . then i tried SleepOver app and i achieved both Local Wake up and over internet too . again both can achieve same things but i wouldn't have done it without good support and recomendations of SleepOver's developer .
so if you get it working either of them IWOL or SleepOver is a fantastic combination with Jaadu VNC and File Magnet apps . you can wake your Mac from say Paris in London then use Jaadu VNC app to browse your remote Mac as if you were sitting in front of you Mac at home the open other end of File Magnet from within Jaadu VNC which is installed on your mac and drag and drop file you want to have on your iphone . then you open File Magnet on your iphone and there they are! file you wanted .

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

Wake on lan - I can't get it to work

Sorry for the nubie here.
I am unable to wake my new iMac from my Macbook using WakeOnLand. The MB is using wifi and the others are using ethernet.
Also, I am unable to see a G4 running 10.4.11.
The MB and iMac are running 10.6.2. No firewalls.
I have a Dlink router and know how to get into its admin page but really am afraid to change its configurations due to lack of knowledge.
Any help appreciated.
Lewis

no. wake on lan works over ethernet only. it does not matter what router you use. but SNow leopard has a new feature "wake on demand" that does work over wireless. but for that you need a very recent apple router (TC or AEBS) and and a very recent computer.

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

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...

Compaq Presario 1714EA (Laptop) (BIOS Update and/or Wake-on-Lan)

Hi guys, can anyone tell me if there is a way to update the BIOS on that Laptop or a way to make Wake-on-Lan work on this Laptop? Thank You

I'm fairly certain that there is not. HP locks out certain features from the BIOS, and there isn't much you can do to get them back.
Though I am an HP employee, I am not here as a representative for them. I am here of my own accord to help those requesting it.
Please demonstrate any appreciation for help with a kudos!
