Autopoweroff is a script that shuts down a computer at a specific time, but only if some conditions are met. It works well on home routers/firewalls where the machine can be switched off every night and powered back up in the morning. It can be configured to only shut down the server after any computers which depend on the server for Internet access have been shut down.
