Scheduling PCs to be turned On/Off via ghost console

Created: 15 Jun 2010 | 8 comments

My current settings:

I installed GSS 2.5.1 on a windows XP-SP3 machine.

Ghost clients are installed on workstations via Ghost console tools' remote client install.

All workstations show up in the "Machine Groups".

I create tasks to turn on/off machines.

I schedule turn on/off tasks via Ghost Console Scheduler

Inside workstations' BIOS, NIC cards have been set to allow NIC to turn on system.


Problems:

Turn-off task only works on workstations that are still in the ON mode.

Turn-on task fails to turn on workstations which are in the OFF state and/or only turn on some workstations.


Ghost software has been configured in the Cisco switches by a network team.

Has anyone experienced the same problems?

All suggestions would be appreciated.

Hello,

You may need to check the option "Use Wake-on-LAN" on the Network tab in the task. A hibernating machine will not receive any task, and while it might seem odd to wake a machine to tell it to shut down, it does need to be able to process the command. 

Thank you,

Randy

Thanks Randy for your response.

Hibernation option is disabled from workstations.

Wake on LAN feature is selected.

Do those NICs have the SecureOn feature? This is a security mechanism that is designed to protect machines from unwanted magic packets by requiring a hexadecimal password. You may want to verify whether they have this feature, and whether or not it is able to be disabled. Not all NICs have this, and I am not sure which manufacturers and models, but I imagine that if you check the manufacturer's website and/or for a setting in the BIOS you may be able to determine this. 

Thank you,

Randy

I checked my workstation, there is no this feature inside the BIOS. The only item in the Security category is "execute disable" is set ON which means "execute disable memory protection is on". I assume that this feature does not relate to "SecureOn".
By the way, workstations are Dell OptiPlex GX-620. NIC is Broadcom NextXtreme gigabit controller.

As far as I know, and I may be wrong, but Wake on LAN doesn't work too well across subnets.  That may be your problem with only select groups of PC's waking up as they may be on the same subnet as the ghost console

You are correct; the magic packet doesn't always go across subnet boundaries. It may be worthwhile to do a packet capture to see if it is going across.

Thank you,

Randy

Thank you both jltrice and Randy. You are correct.
Workstations are on 2 different vlan. I've been advised trying to set Ghost console on each vlan. Only workstations which are on the same vlan with Ghost console will be turned on.
I informed network team to take a look at Cisco switch. Anything I can do (from my end) while waiting, such as enable tcp/udb ports to let WOL pass thru?

I got this from the wikipedia article on Wake-on-LAN:

"Since the magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it may be sent as a broadcast packet of any network- and transport-layer protocol. It is typically sent as a UDP datagram to port 0, 7 or 9, or, in former times, as an IPX packet."

Here is a link:

I hope that helps!

Thank you,

Randy
