Hello!

I have a small network at home.

I want to setup the gateway/router Debian Etch to wake up the server box with
wakeonlan.

The server box - Debian Etch has enabled the "Resume on LAN" field in
the Power Management Setup of the Award BIOS.

The server box have also a NIC with wake on LAN cable properly set up.

When I run the command wakeonlan the server box wan't not to wake up.

I use the right MAC address of the servers NIC in this command.

Why can't I use wakeonlan to bring up the server from the gateway?

Any advices will be appreciated!

I never used wake-on-lan, but I see from the description of the
wakeonlan package that it used UDP packets in order to avoid the need
for root. Maybe you should also try etherwake?

Maybe I don't understand the description of wakeonlan:

"You can wake up WOL compliant Computers which have been powered down
to sleep mode or start WOL compliant Computers with a BIOS feature."

Well, if I power down the server with "shutdown -t 1 -h now" then I
can't to wake it up with wakeonlan?

Have you tried suspending (hibernating) the system and then waking it
up? If I understand you correctly, you are trying to power up a system
that is not in suspend-to-disk or suspend-to-ram mode, but off.

I have never used a system with a NIC that actually has a special cable
for Wake-on LAN (my cheap NICs were always regular PCI ones without that
connection) and I haven't read the docs for wakeonlan, so I am not sure
if that makes a difference, but I always thought (and verified by
experiment for my hardware) that I needed to suspend the system for WOL
to work; starting a machine which had simply been powered off with the
shutdown command never worked. Again, maybe this is possible with
certain
hardware, but it would certainly be special.

Wake On LAN wakes a system from poweroff. There is no need to suspend or
hibernate.

I red in the motherboard manual:
"... It will allow the network to remotely power-on a Soft Power Off
(Soft-Off) PC. However, if your system is in the Suspend mode, you can
power-on the system only through an IRQ or DMA interrupt."

I red here too:
"Important: The 5VSB power source of your power supply must support
greater or equal 720 mA."

I shall to see my power supply for that attribute.

So, if I shut down the system with 'shutdown -t 1 -h now' then I have
a Soft-Off PC, right?

Not sure of if it but try google on wakeonlan + free ,
you should find something in french, but internet addresses should be

You have to ensure that the network card is not powered down when the
system is shut down. After shutdown, check whether the LEDs of the
ethernet adapter are on. If not you may have to use `ethtool` to ensure
that the ethernet card is not powered down.

I use `ethtool -s eth0 wol g` to achieve this.

On my Centos box i also had to do the following to get it to work:

ethtool -s eth0 wol g
echo PCI1 > /proc/acpi/wakeup

cat /proc/acpi/wakeup

Device Sleep state Status
PCI0 4 enabled
PCI1 4 enabled
PCI2 4 enabled
UAR1 4 disabled
UAR2 4 disabled
USB0 4 disabled
USB1 4 disabled
AC97 4 disabled

I have setup 'Enabled' in BIOS 'Power Management Setup' the 'Resume on PCI
Event' too, soo finally I can to wake on from gateway/router my server
box with wakeonlan.

I must to give too the proper Broadcast address to my LAN.

Check the BIOS or motherboard specification, but the machines I have
which can use WOL *must* be powered off fully, they won't wake from any
kind of sleep or standby mode. The specification may state which S modes
the WOL will work on.

However I can't wake up the PC box debian server from the debian
gateway when I power off the debian server with shutdown command and
after that I plug off the power cable of the PC supply.

But when I power on the debian server with it's power button and right
after that I power it off with power button, then I can to wake up the
debian server from the debian gateway with wakeonlan command.

What cause this event?

I set up in debian server's Award BIOS the following:
* Integrated Peripherals / Onboard SuperIO Device / PWR Lost Resume
State: Turnk On
*Power Management Setup / Resume On PCI Event: Enabled
*Power Management Setup / Resume On LAN: Enabled

When the abowe mentioned PWR Lost Resume State was: Off, I can't too
to wake up debian server with wakeonlan.

I check that the power supply of the debian server has +5VSB / 2A and
that is enough to use wake on lan.

Why can't I wake up the debian server from the debian gateway with
wakeonlan?

Any advices will be appreciated!

Warning: I do *not* know what I am writing, so please correct me.

I suspect that when the power supply is "completely off" (first case),
then the harware (the nic) loses the status that makes it able to wake
on lan (a manual boot, with the re-initialization of the nic by the bios
would be necessary to re-enter the "wake on lan" status)

You might have success putting 'NETDOWN=no' into the file
/etc/default/halt (if it doesn't exist, just create it). I have read
somewhere that it should make sure that the NIC isn't powered off on
shutdown and /etc/init.d/halt appears to use this value. But it didn't
in my case. Wake on LAN only works after Windows has been booted.
