I was interested and have working WOL from the lan side. works fine but useless. Im using remote VNC Enterprise. i would like to use wake on the WAN side. I had an issue a few days ago go to familys house and realized the computer was off. Of course nobody was home to turn it on for access. Any suggestions for software i might use. maybe free, but buying isn't a big issue for a reasonable price.
 
Check the BIOS for that option. If it is available, enable it. It works like a charm.
You may have to set the VNC software to start with Windows.
Be aware, WOL may prematurely start the PC when you don't want it to (any network activity will start the PC).
 
If you are behind a router at home see if there is any config for your router to allow WOL connections from a WAN.
 
i did. maybe it was a pipedream.
Will see........i was more curious than anything.
would be useful though at times. ill be back if i find it.
thanks
 
Well wake on LAN and lights out technology are two different things. Lights out lets you remotely power on a system and wake lets you remotely wake a system, since putting it to sleep kills most processes. So, if you were to try to ssh into a machine that was a sleep, normally it would kill the connection because it would shut down the ssh daemon. The WOL still requires the machine to be on, however with certain ACPI technologies you can have a machine practically turn itself almost completely off but still retain some power (typically in the NIC) for further transactions.

Lights out technology allows you to set a specific NIC that always has power and you can remote into the NIC's IP and power the system on, typically either through a web interface or through a VNC or remote desktop type connection.
 
Thanks tlarkin. i seen lots of info on lights out. you seem to know something about it. when i get a window or weekend i will follow up more. it just got more confusing. i'll reply more when i have time.
thanks
 
Try tomato firmware if your router supports it, has WOL ability.
You can then connect to the routers console over the net and turn your machine on.
WOL does not work with any LAN activity, it is a specific packet called Magic Packet.
 
lights out management came as as standard on my hp/compaq server but i never used it, just standard WOL. Quite handy really, i downloaded a utility for my PDA where i can send magic packets from it, thereby waking up computers with ease
 
Depends on your definition of powered off, WOL will work with Soft Off (ACPI - G2)
G2 is initiated from the OS, so the NIC will therefore be active and responsive to WOL broadcasts

Completely turned off, is what I meant, not a soft off which is similar to a hibernate.

No, hibernate is a function of the OS where OS state is dumped to disk.
Soft off is as good as a mechanical off - except that certain components remain powered e.g. the NIC
