Description-en: System to shut down clients at night, and wake them in the morning
With this tool you can schedule regular shutdowns of workstations in the
evening, and also wake them up every morning, using either nvram-wakeup, ACPI
wakeup or wake-on-lan.
.
For the wake-on-lan wake-up sequence you need one awake machine on your local
network / subnet. This can be a server machine or a client machine that got
just previously woken up by nvram-wakeup.
.
The shutdown sequence will be initiated hourly after 4pm via a CRON job.
However, only machines that appear inactive / unused will be shut down.
Machines that are currently in use will remain up and running.
.
The Shutdown-at-Night tool can be activated via a config file or via
membership in a NIS netgroup called shutdown-at-night-hosts.
