WOL - how to?

[oshta]

i was wondering how can i "wake" a PC remotely using WOL acrross my home network (wired)

- do i need a progam like Radmin?



- thanks. daniel

ping it

[oshta]

well, i just tryed that and i get nothink?

- when the PC is on, i can ping it fine, but when i ping it when its off i just get "operation timeed out" or what ever

- one of the pc i tryed has onbaord lan (abit at7max2) and the other has a sitcom PCI NIC (with onboard WOL, and the cable into the mobo)

I think you need specialist software and a static arp on the box sending the signal to wake up. You could try adding a static arp and then pinging and see what happens.

To add a static arp goto the machine which is to be woken and do an ipconfig /all(windows) ifconfig eth0 (linux) and note the mac address down, sometimes called the physical address. Or you could try pinging the machine whilst its on from the other machine, and use the command arp -a to display.

On the machine that is trying to wake the other machine use the command :-

arp -s <Ip of the machine to be woken> <MAC address of the machine to be woken>

Then try the ping again. Cant remember the exact syntax for adding a static arp in linux but it uses the same command arp.

eg :-

C:\Documents and Settings\Mark>ping 82.68.48.38

Pinging 82.68.48.38 with 32 bytes of data:

Is this with onboard network card or for a add on network card ?

[oshta]

both, one Pci NIC, two onbards (as in my previous post)

[Jiff Lemon]

Have you shut the machine down or put into standby?

WOL will, IIRC, only wake from standby.

not iirc the network card still has power and so will the onboard nic (modern mobos provide power to the pci slots even when it's supose to be "off"), it just needs the magic packet that tells it to wake up.

All i can say on this is have you tried google ?

Try adding the arp as I posted above. If I remember correctly tho I think you have to have special software to send out the right packet to force the machine to wake.

http://gsd.di.uminho.pt/jpo/software...i-howto-2.html should explain the technical side behind WOL, but if using properly written software you shouldn't need a static ARP even when using IP packets to encapsulate the magic packet as that's what the broadcast address is for.
