Server auto-suspend?

[fkjensen]

Looks like that could be it! Thank you.

Can I use apt-get to install it? I can only find a tar.gz-file, and although I am sure that would work just fine, I am a total linux-newbie, and I have only used apt-get so far

Is it included in 9.10? I am currently running 9.4.

This should do it:

sudo apt-get install powernap

Just installed it but not even read the man page yet so need to investigate the possibilities....

Hmmmmm looks fairly broken to me:

* Starting powernap Cannot get device settings: Operation not permitted
Cannot get wake-on-lan settings: Operation not permitted
Cannot get link status: Operation not permitted
Traceback (most recent call last):

Ooops spoke too soon sorry, you need to be root to restart the daemon

sudo away. I'm looking for similar functionality, keep us informed.

Do you run 9.10? I don't think it's part of 9.4, as I can't install it with apt-get.

I've just installed it on 9-10 and it does work ok for suspend but I've not tried the other functions.

[fkjensen]

How do I install it on 9.4?

Look at the launchpad pages for powernap, I think you have to add a PPA to your apt sources file, there are versions in the main repos for jaunty and karmic but for older versions you need to add the PPA.

Progress up to now...

Powernap works at shutting down NAS server after 5 minutes of inactivity. To use powernap with pm-suspend, an 'action' file needs to be created and made executable in etc/powernap/
I've also created an icon on my kubuntu client which when clicked will wake the NAS, this also works well. Which means that starting the NAS from a client computer start is also easily accomplished by setting a script in KDE's autostart.

The problem I have right now is that sometimes the NAS wakes and doesn't fully load....

...I'll check the logs!

Hi Muttley

What processes are you using to keep the NAS/server up (via the config file) ? I've been trying to find one that don't keep it up all the time, without much success unfortunately

I want my box to provide Squeezebox streams plus files and print services to Windows clients both via Samba then sleep when not but the processes associated with these services never go away and hence powernap never powers down.

It's not much help to you but my box goes down and up from suspend and hibernate using WOL 100% reliably, my plan is to add a script to the action file to put the box in suspend for a period then take it down to hibernate if not used for a further period.

Cheers
