Fwd: Wake up time
Begin forwarded message: From: Anselm Strauss Date: September 22, 2009 8:55:42 PM GMT+02:00 To: Don Brearley Subject: Re: Wake up time Good idea. Would work for my setup, my router should be always on. And I think there is a wakeonlan port for FreeBSD. The advantage of this solution would be that I can trigger a wakeup on very dynamic events. If I set the wakeup time in the BIOS it's rather static, and I have to know the next wakeup before I shut down the host.

Re: Wake up time
That would be a possibility. Although I prefer a solution without additional hardware. Also, I'm not sure, if it's good to constantly disconnect the board from power. Well, it's certainly better for your power bill, but maybe not for the BIOS battery. I know that my BIOS supports setting a wake up time (you can set only the time, and it will wake up each day on that time). I've just discovered the /dev/nvram device and there is a program for Linux called nvram-wakeup, that uses the nvram device to set this wakeup time from the OS. One can then compute the next wakeup time (within a day) at every shutdown and write it to the nvram. I have to see if this program also compiles/runs on FreeBSD ...

I have a machine I would like to regularly shutdown and wake up at different times depending the on the day of week. The easy and cheap way to accomplish something like that is to put a timer between the machine's power supply and the power outlet, and use a script started at boot to switch the machine off in a controlled fashion after a specified time before the timer runs out. The only inflexibility in this scheme is that timers usually require a time to switch on and a time to switch off. So if you need the time that the machine is "awake" variable, it won't be as easy.

Wake up time
Hi, anybody knows if it's possible to set BIOS wake up time in FreeBSD. I have a machine I would like to regularly shutdown and wake up at different times depending the on the day of week.
