HOWTO: Set your system up for Wake On LAN (WOL)

[Big_Croc7]

I think you've probably set it to wake on a unicast message rather than a magic packet. One way to test this is to send anything (e.g. a ping) to that machine and see if it wakes up. This would explain why it doesn't work after a long time, as your router might cache the physical location of the IP address for some time then clear it. Try experimenting with the umbg switches (e.g. ethtool -s eth0 wol bg) - u = unicast, m= multicast, g = magic packet and b = broadcast address I think, or maybe that's not quite right but you get the idea.

Has anyone got WOL working frin the Internet with a BT Home Hub router? I'm having difficulty and the 'Big_Croc' method isnt helping. The BT Home Hub is pretty configurable so I'm hoping someone has worked out how to do it

This may help port forwarding-

I haven't tried by myself yet, I am currently sshing my server over internet but WOL I have to still configure. Probably will try UDP port forwarding for that.

I suggest using etherwake instead of wakeonlan
(sudo apt-get install etherwake)

I experienced problems, when using wakeonlan script on OpenVPN server bridged with local lan with Shorewall enabled. No such problems with etherwake.

What if you have 3 Ethernet Cards like me? lol

Hey everyone, I have a few questions about WOL
I've gotten WOL to work within my home network with the comand
wakeonlan 00:00:00:00:00:00 and my server powers up fine, but when at home it's not that much of a convience because I can just walk to the box and press power. I dont know however how to get this to work outside my network.
also Im not sure how to use wakeonlaa properly, the -i and -p options dont seem to work for me. Im not sure how to type them
for example i've tried to wake up the server from outside the network with the command
wakeonlan -i 76.120.108.232 and I get (ip address) is not a hardware address and could not resolve it as an ip address. just the command
wakeonlan -i gives me the menu of commands
do i need to braket the ip address?
i've got my router fowarding port 9 udp to the servers priviate ip, and that is assigned by it's mac address.

Hey

WakeOnLan needs the mac address of the machine you wish to power up so what I do is put the mac address in a text file and run the following

wakeonlan -i YOU_IP_ADDRESS -f mac_address.txt

Hello,

I want to share my findings of WOL using the 3c905b-tx NIC.

My computer is an old HP Vli8 pIII with an 3c905b-tx NIC with a WOL cable connected to the Mobo

Following two ways worked (first connect the cable to the mobo and enable network wakeup in BIOS):

1. manual way
rmmod 3c59x
modprobe 3c59x enable_wol=1 global_enable_wol=1
shutdown -h now
Then send magic packet (UDP, port 9)

But this way i had to arm the computer manually after each startup

2. Automatic way
Added to /etc/modprobe.d/network
alias eth0 3c59x
options 3c59x enable_wol=1
options 3c59x global_enable_wol=1

rmmod -f 3c59x
update-initramfs -u

shutdown -h
Then send magic packet (UDP, port 9)

Note that i used the -f flag on rmmod, it was not possible to unload the 3c59x module otherwise (please use with care)


Both two ways worked fine on my old computer, hope it helps someone else with the 3c905B-Tx card

(don't forget the sudo above, i did not include it to be more clear)

regards,
Anders

Hi everyone

I have a new mainboard GIGABYTE GA-EP35-DS4 and have problem with WOL. After shutdown I can't wake my pc. Bios is set ok, but led on ethernet port is after shutdown off. On my ASUS P5N-E board ether script with ubuntu hardy works perfec, but with Gigabyte and hardy doesn't work
I'm using ether-wake.

Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: g
Current message level: 0x00000033 (51)
Link detected: yes

any idea?
Thx

I have the same problem with a Gigabyte mobo. I have a feeling that it may not support WOL. See this post:

It should work with the Gigabyte board. I have a Gigabyte P35-DQ6 board and WOL works just fine (unfortunately I haven't tested it with Ubuntu since I'm only running XP on that pc).

Recently I built a server with a Abit A-S78-H board with a 780G chipset and it has a Marvell 88E8056 PCI-E Gigabit Ethernet Controller. Although I set Wake On Lan in the BIOS and used ethtool to use WOL, it still doesn't work. I also adjusted the halt script to remove the -i option but no luck. The light on my LAN-port doesn't light up when I shutdown the server. Btw, I'm using 8.10 server amd64.

Are there others that have the same problem?
