[Alix 2] Basic working solution to drive the front LEDs

[PatrickB]

Hello.

Sorry I still have no solution to make a front LED of the Alix show the network activity. 😥

But I could find a little program with some features and doctor it to provide the basic functions. This script is self-explanatory.

I did not implement the CPU and disk activity, it would be easy to add. But my LED #2 is reserved for WAN activity, when I can do it… 🙄

# set-alix-led.include.sh

#

# This script can be included by any script having to drive a LED on a Alix system.

#

# It relies on the very limited possibilities of the operator alix-leds that can be

# found there:    http://linux.1wt.eu/alix/util/

# - the executable can be found in alix-leds-3.0-flx0.1-i386.tgz,

# - the source file can be found in alix-leds-3.0.tgz (for real functionalities).

#

# Arguments:

#

# $1 = 1|2|3  (actually not verified, if you want to play, have fun...)

# = the LED to operate. LED #1 is the leftmost, normally it is permanently lit on Alix.

# $2 = on|off|slow|fast

# = what to do: switch on, off or set to blinking slow or fast.



ZtNicAlwaysUp="ETH01"

ZtNicNotExisting="ETH666"



SetLed()	# $1 = 1|2|3,  $2 = on|off|slow|fast

{

# Here is all what I can do with that poor operator 'alix-leds':

# - start monitor an existing/unexisting NIC to tun the LED on/off,

# - immediately kill the process become useless :-(

# - for slow|fast blinking the process must remain,

# - so it has to be killed first before any change.



ZtPidFile="/tmp/SetLed$1.pid"

if [ -f $ZtPidFile ]; then

kill $(cat $ZtPidFile) ;

rm -rf $ZtPidFile ;

fi

case "$2" in

on)

alix-leds -l $1 -i $ZtNicAlwaysUp -p $ZtPidFile ;

kill $(cat $ZtPidFile) ;

rm -rf $ZtPidFile ;

;;

off)

alix-leds -l $1 -i $ZtNicNotExisting -p $ZtPidFile ;

kill $(cat $ZtPidFile) ;

rm -rf $ZtPidFile ;

;;

slow)

alix-leds -l $1 -r -p $ZtPidFile ;

;;

fast)

alix-leds -l $1 -R -p $ZtPidFile ;

;;

*)

echo -e "set-alix-led.include.sh: SetLed( $1, $2) not implemented.n"

;;

esac

}

Now I use this script in my project [Janus / twin Alix2] and it works very fine. 😀

Hope it can help.
