A possible solution which doesn't seems to be sophisticated as the one you are looking for is a remote console. 1. Have the BIOS restart the machine when it can. 2. Make the Linux boot loader wait for confirmation on the console before it continues. 3. Use a remote console: see the Remote-Serial-Console-HOWTO. Alternatively you can have the machine boot by default into a runlevel which does not provide full services but still gives you sufficient means to switch it from a remote location into one that provides full services. > > On Wed, Jul 10, 2002 at 05:43:21PM +0300, Hetz Ben Hamo wrote: > > Hmm, > > > > As much as I know - WOL (Wake On Line) is totally disabled when you power off > > your machine from the power switch on the back of your machine... > > > > As for electric break - I think you can set it up in the BIOS (don't remember > > which function).. > > > > Hetz > > > > On Wednesday 10 July 2002 17:03, Yedidyah Bar-David wrote: > > > Hello, > > > > > > Sorry for being off-topic. > > > > > > Did anyone here try wake-on-lan and cares to share the experience? > > > > > > Specifically, I have machines that wake up well usually, after > > > being shutdown by software or by the front-panel power button, > > > but not after turning off and on the button in the power supply, > > > or, more importantly, after an electricity break. > > > > > > For those interested, I use ether-wake from > > > <http://www.scyld.com/expert/wake-on-lan.html>. > > > > > > Do others have better experience?
