Here are some tips and tricks about running Debian on the QNAP TS-41x/TS-42x.
Automatic fan control
Debian ships a program called
qcontrol which can be used to control the
fan, LEDs and buttons on QNAP devices. You can edit the
/etc/qcontrol.conf configuration file to change the behaviour of
qcontrol, for example how the fans are regulated depending on the
temperature or which commands to run when a button is pressed.
You can tell your QNAP device to power on at a specific time using the
wakealarm system. For example, if you want your QNAP to power on in 5
minutes, issue the following commands and turn off your device:
echo 0 > /sys/class/rtc/rtc0/wakealarm echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm

qcontrol --direct autopower on
