System Standby For Untangle

[datdamnmachine]

Not sure this is the right forum but I figured I'd give it a shot here. Basically, I have my Untangle box protecting my home network. What I would like to do, is be able to manually place my Untangle box in power standby. Also, if possible, I would like to schedule a standby time. For example, I'm usually not on the computer from 2am - 7am so it would be nice to schedule the system to go into standby during that time. It would help save some power when the system is obviously not in use. Let me know if this is possible and if not, I'll submit a feature request.

Oh, and I'm talking S3 standby-to-memory.

If your BIOS supports "Wake at $time" you can set it for the wakeup, and put a cron job to sleep or just shut down the server.

Cron job, do tell. As many others, I am new to the whole "Linux" thing.

Should I use the obligatory ?

I will be searching on my own but at the same time, any help is always appreciated.

The Microsoft "System Scheduler" is a bad copy of cron. (Simele overview at http://www.tech-geeks.org/contrib/md...ron-howto.html ) You can put in a command (like 'shutdown -P now') that will shut down at 2:15am, and the computer will turn off.

Now to come back on, your BIOS for your computer must have a wake at time function to turn on at 6:50am.

I've been looking for power saving modes for UT for a while, since, on my hardware, bootup time is 6.5 minutes and that's something I want to improve.

Anyway, my hardware supports ACPI "standby" (S1) and "disk" (S4), but nothing else.

S1 works (in a Bash shell, not the default Z shell) using:

echo -n standby > /sys/power/state

Though it works, in my hardware, only the HDD powers down - everything else remains powered, including the graphics adapter (on the mobo). The power savings being so meagre, there seems no point to doing this.

S4 initially seemed to work (again in a Bash shell) using:

echo -n disk > /sys/power/state

... but on resuming, only the Linux boot sequence is saved - the UVM reloads from the start, which takes nearly 6 minutes (from the 6.5 minutes for a full bootup from power off) so, again, there seems no point to doing this.

That therefore leads me to a feature request: adding a Suspend-to-Disk feature to Untangle that will work without the long UVM reload.
