I know this is an old thread, but here's something that might work. I have a Wheezy system running LXDE and if you try to shut down using the gui while another user is logged in, it refuses. Actually, I think it requests the root password. So if your backup process involves an ssh login of a regular user (uid of 1000 or greater), other users won't be able to shut down the computer by normal gui methods. -Rob signature.asc Description: Digital signature
Re: Preventing the computer from shutting down.
Thanks everybody for their help. I will use molly-guard to guard from accidental shut down from the CLI. Is there something like molly-guard for the LXDE power off/close session button?. I must clarify that what I mean by “preventing the computer from shutting down” is preventing the operator from inadvertently shutting down or rebooting the system while it is undergoing a backup. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

I'd try to fix the bug that makes it shut down. Do you have broken hardware or power failures, or is there something running that randomly shuts it down? PS: Look into /etc/X11 for some freedesktop.org directory. It may have some policy xml files you could modify to disable the shutdown. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us.

Instead it implements, e.g. /usr/sbin/shutdown. Since /usr/sbin precedes /sbin in $PATH this allows them to be overridden. A bit clumsy, I agree, but sufficient to prevent administrator mistakes. Personally, I would have preferred molly-guard to use dpkg-divert, but it works as it is. > This is probably at least a documentation bug, and possibly a real bug. In the case of molly-guard, I belive that is up for debate. It only intentds to be a safety net, not a security feature.

I think that you can get *some* of the way by installing the molly-guard package. Although molly-guard is primarily aimed towards preventing system administrators from blowing their feet off, it does allow the system adminstrator to add in scripts in /etc/molly-guard/run.d which can prevent "shutdown" or "poweroff" from working. It's a safety net - not a guarantee. And it is reasonably simple to bypass by a half-competent admin. I doubt this affects the LXDE power off button though. (I do not use LXDE).

If you're using systemd, this can be done using systemd-inhibit. See http://www.freedesktop.org/software/systemd/man/systemd-inhibit.html for details. Quickly: systemd-inhibit --who='backup script' --why='backup is running currently' \ --mode=block yourbackupscript; Otherwise, you can add in an init scripts which runs in rc6 and rc0, and blocks until the backup is done.
