Title: automatic shutdown
Post by: Maniac on April 10, 2007, 11:29:45 AM

hi everyone!

I couldn't find a solution for this problem, so I'm posting here:

Is it possible to let the server automatically shut down every day at a specific time?
Starting up is no porblem, this is easy to setup by bios.

Is there a plugin or something?

thanks, Maniac

You can set up a cron job to do this.

Yes, you will need to run the 'shutdown' command in a cron job.

Do a 'man shutdown' to see how to use it.

An alternative is 'signal-event halt' , also run as a cron job.

Are you certain that your bios can wake up at a certain time everyday ?

ok thanks, I'll try this..

Yes, I tried it. The function in the bios is called "wake up by date"

It took some time today (cause I'm a noob  :wink: )but now the Server starts accurately at 10 o'clock and shuts down at 0, friday and saturday at 2.
This will save a lot of energy over time.  

my crontab file:

MAILTO=root
HOME=/

0 0 * * 1-4,7 shutdown -h now
0 2 * * 5-6 shutdown -h now

I advice you to use the signal-event halt instead of the shutdown command, as this is a SME Server specific event which might handle other things which are not done with the shutdown command (no wor in the future).

My advice is not to do shutdown/start-up stuff like this as you risk loss of data and corruption of data, this might in the end cost you more than your energy bill.
