Remotely sleep/hibernate networked computers

peustace

Hi all,

We are trying to implement a system in work where you can remotely sleep/hibernate a large number of computers from a centralised location.

My searching online I've found http://www.rshut.com/ which is quite good but unfortunately not freeware which we could ideally look for.

Have anyone used something that can do something like this? I know you can run a batch file to shutdown a PC but not sure if this will work for sleeping PCs.

Any thoughts?

Cheers

What are your specifics?

Do you need to do this at any time? Or is a specific time of day enough?

Jumpy

Also how many systems are we talking about?

Secondly do you need to wake them again?

Have you looked at Wake-on-LAN? http://en.wikipedia.org/wiki/Wake-on-LAN

Here is a nice little tutorial with PHP code (from 2006):

Sorry I see the hibernation has been answered by corkcomp. I just scanned the original question. You can use the 'swsusp' command in more recent Linux kernels.

The usual sticky is restarting the machine hence my pointers to WOL.

I presume your talking client PC's rather than servers?

do you need to be able to wake again remotely also?

no prob having a batch file - use this command
"%windir%\system32\rundll32.exe powrprof.dll,SetSuspendState Hibernate"

Sorry guys, just getting back to this.

Ideally we would like to be able to remotely sleep/hibernate/shut down about 30 client machines. Not a huge number.

If we could remotely wake them again that would be nice but not a deal breaker. Just reading up on the links provided, cheers for the help

psexec is great to run commands remotely
like shutdown.exe - both on the microsoft site
not a remote hiberate though


to wake up - you need to send a magic packet to the MAC address of the card amd do a utility for this
dhcp should have a list of MAC address and IP's
DNS will have a list of IP's



don't forget to setup wake on lan in the BIOS
also set power save to the correct level , the one that uses a little more power in standby
also set wake up on lan on the network card in windows power management too

If they are all on a Windows Domain you can push this via GPO.

You can also disable the screensaver and put the monitor into standby after a set period of time {after 15mins of inactivate}.
