The only other thing being in group operator lets you run,
apart from what you've added into /etc/devfs.{conf,rules} is
/sbin/mksnap_ffs ..
In a default devfs config, it grants read permission to
the disk devices (presumably to enable running dump(8)).

True, so if Gilles' dad really wants to run dump, he most likely can.
The .snap directory in the root of a (mounted) file system to be dumped
has owner root, group operator, mode 0770 - paraphrasing from dump(8) -
and then he'd need mount and write permissions on the dump destination.
Doesn't sound too risky if Gilles trusts him enough to run shutdown :)

[6.3] Assigning shutdown to eg. Syst?
Hello I'd like to make it easier for my dad to shutdown a server. Instead of having him plug a keyboard, log on as root (with a complicated password) and finally type shutdown -h now, is it possible to assign this command to some unused key like eg. Syst? Even better, send this command only if the key is hit eg. three times within 2 seconds?

Even better, send this command only if the key is hit eg. three times within 2 seconds? I have a similar setting, but it requires X, WindowMaker and a Sun Type 6 USB keyboard. :-) Short explaination: I have assigned the command xterm -class SHUTDOWN -fg black -bg red -e shutdown -p now ; read DUMMY to the key combination Ctrl+Alt+(I) - the switch off or moon key on the top right. This combination is impossible to press accidentally. (Without Ctrl and Alt, this key closes the X session and leads back to xdm for login.) You could add a clickable menu entry or desktop icon with this command, but make sure it's not accidentally clicked. :-) If your father is already logged in, he could shutdown -p now (or using an alias) from an xterm. He needs to be in the wheel (or at least operator?) group for this. What about pressing the power button on the machine itself, it should perform a shutdown -p now (shut down and power off). By tht eay, the key you're refering to is named System Request, or SysRq. -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The full list of actions isn't documented anywhere, but all you need is 'boot'. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Just add him to the operator group so that he can run /sbin/shutdown. If he's shy, write him a little script that does 'shutdown -p now [comment ..]' Shutdown is cleaner than reboot, runs 'stop' rc.d scripts for all active daemons, and leaves a nice log entry in messages, including any comment. cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
