If my Mac goes to sleep, will JBidwatcher not function?

I’m using an iMac running 10.6.2.

The sleep settings are currently configured as follows:
Computer sleep: 10 mins
Display sleep: 10 mins
- Put the hard disk(s) to sleep when possible [checked]
- Wake for network access [checked]

Since I have the box “Wake for network access” checked, will that mean that JBidwatcher can function?

Or do I need to move the sleep time sliders all the way to “Never”?

Thanks for the help

“wake for network access” will most probably not include the internet connection (because there is no action caused by an external source)

Greetings,
In JBidwatcher there’s a FAQ, under Help… This question is #17:

Q. I have a laptop/sleep-enabled computer. What if it goes to sleep?

A. When most computers go to sleep, they are not running any software, including JBidwatcher, until they wake up again. Often they will shut down their network connections, too, until they wake. This means JBidwatcher will not be able to snipe while the computer is asleep. Make sure to disable sleep mode well in advance of any snipes you want JBidwatcher to fire.

Greetings,
And just to clarify, ‘Wake for network access’ is specifically to allow a specially crafted incoming packet on your network to wake you computer, not for your computer to wake when any application requests network access. Again, remember, when your computer is asleep, it’s not running any software.

‘Wake on network access’ is actually implemented in the firmware of your network card, where it passively watches the wire even during ‘sleep’ mode (because code can run in firmware on your network card when the main CPU is asleep), for the specially constructed packet to appear.

You can sleep your display, but if you’re sleeping your computer, then JBidwatcher won’t be able to snipe.

I’m working on a solution, but it requires using a 3rd party sniping service.

With OS X it is easy to set events (at least with applescript, or other scripts) to wake a computer from sleep at a specific time. Maybe windows has something similar? I’m pretty sure linux does not at the moment.

I don’t know how easy it is to do this from java. Perhaps one could provide some hooks for a platform specific wrapper script?

According to

Acpi wakeup can be used on any sufficiently modern computer to set a wakeup time by saving a time to the bios. Java is designed to prevent this kind of thing…
