Topic: WOL for SME

When server Shuts down when electricy is Off and dont turne on !!

How to send WOL signal to it and how to enable this service on server!!!

[Ray Mitchell]

I'm just guessing what you ar after here, can you explain in a bit more detail if this answer is not what you want !!

If your machine shuts down when power fails and does not restart when power returns you need to change the BIOS power up options, so that the machine will start up when AC power returns. Most modern BIOSes have this option.
Does this help ??

WOL=Wakeup On Lan, what it's designed to do is turn a machine on when it is pinged.  How can a machine that is not on be pinged?  I have no idea.  But that's what it does, my motherboard supports it, but my network card does not.  Your OS also needs to support it and I have no idea if Red Hat does.

Thanks Terry WOL went straight through my head

Dear Free_one

Would this work ? Just thinking out load. I have not tried this but I will later on.

If your workstation NIC & motherboard supports Wake on LAN and you configure your windows workstation to respond,
then logon via VPN to your sme server and either
ping the workstation IP
or
run net use X: \workstation IP\workstationsharedrivename
from the remote PC
This should create network activity which should (?) turn on the workstation.

Anybody have an opinion whether this will work,

Dear Free_one
Sorry my post referred to getting a workstation started using WOL, not the server.

I would ask why would you have your sme server turned off, it's designed to be left on all the time. If you use a UPS and have it (and the server BIOS) configured correctly the server will restart when AC power returns.

If you really want to remotely turn on your server then you might try one of those dial in electronic switches connected to your phone line and server power outlet. When you dial the device and enter a code it turns on the power to the server or whatever you have plugged in to it.

I agree. WOL would seem to work to restart the server after a power outage, but there should be a BIOS option to do that, which is much easier...

From what I have read the WOL sends a message to your MAC address to tell the PC to wake up. If your PC is off the OS cannot assign an IP to the card. But if the NIC is WOL capabel it will receive MAC address commands.

Keep in mind that just because the system is not "on" does not mean the components are not powered. Many systems leave the NIC powered, and some leave onboard modems powered, so the system can do wake-on-LAN or wake-on-ring startups. Some even do wake-on-key (a nod to the Macintosh!) and I've even seen a few with wake-on-clock options.

For the SME server, small UPS units are cheap. Install one and configure the BIOS to power on when power is restored.

For workstations, you could do the same; however, if the workstations are WOL compatible, then write a small script to do the WOL probes when the server is restarting. Then you can bring the entire network back up automatically.

Thanks,

It helped I just configured my BIOS and it weak up when power returnes to UPS

Many thanks

I have been trying to do just this...eg wake up an e-smith server using WOL for a very long time. Reason ? Simple. I want to run a remote machine, (in a bunker in my garden actually) when I want to do a back up to its disk. SO to avoid any possibility of a network-wide problem with say Klez, I want it off when I am NOT doing a back up. (All this lot is via samba...I got a dose of KLEZ earlier this year and I DO NOT appreciate the changed dates on all my files resulting from the debacle.) I have FINALLY managed to get a SME 5.5 server to wake up using a simple Windows GUI. Im still trying to find out how to make the machine suspend itself when I shut down SME using the web admin interface. I am also struggling to make the damn machine STAY in suspend when I have put it in that state with the button on the front of the case..let alone by remote control. Any ideas ?
