shutdown -h now from a cron job on the server that's run on each client. The server should have ssh keys installed for root onto the clients so it's pretty easy to script up a shutdown process. Alternatively, add a cronjob in the /etc/crontab for the clients that shuts down daily at say, 8 pm. But then you must have time synched properly. <div class="gmail_quote">On Sun, May 29, 2011 at 10:36 AM, Phydeaux <<a href="mailto:reb@taco.com">reb@taco.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi! After spending a couple of hours cleaning the dust out of our client machines and reading the discussions here about power savings, it occurs to me that I'm missing something. Despite my encouraging both students and teachers to turn off our client machines at the end of each day, nothing is ever turned off. How can I force our ltsp client machines to power off? I'm happy to pick a timeframe of two or three hours of inactivity. At that point I don't really care what the machine is doing -- I just want it off. I would imagine that there is some way to set this within the client image (not that I care where it is set). I've done some digging and have not found any way of doing this, though. We're running ltsp5 on Fedora 13, if it matters.
