The GUIs only provide a button/menu item for the user to use, you want to remove or restrict the command that they refer to. Probably removing the "other/all" users execute permissions on the reboot, poweroff, and halt commands, would do the trick. You'd also want to remove the wires from the boxes reset and power switches, and make sure that CTRL+ALT+DEL, and probably CTRL+ALT+BACKSPACE are masked out. The latter two, I don't know where to do that. You might want to try reposting with a better subject line to catch the attention of someone who knows these tricks. Such as, stopping unauthorised users rebooting or shutting down the PC. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
