Mkiv Led Connectivity Indicator

Hey All,

This is just a simple script I wrote to help troubleshoot, maybe someone will find it useful.

It pings two IP addresses, then turns on or off the unused LAN/WAN LEDs based on the result.

This code runs an infinite loop, DO NOT add directly to rc.local.

#!/bin/sh
# Turn LEDs on/off based on network connectivity
# $LAN_HOST controls Lan LED, $WAN_HOST controls Wan LED 
#
WAN_HOST="8.8.8.8"   # Wan host to ping
LAN_HOST="172.16.42.42"   # Lan host to ping
################
WAN_LED="/sys/devices/platform/leds-gpio/leds/alfa:blue:wan/brightness"
LAN_LED="/sys/devices/platform/leds-gpio/leds/alfa:blue:lan/brightness"
while : ; do
	LAN_CHK=`ping -c 1 -w 4 $LAN_HOST | grep received | cut -d ' ' -f4`
	WAN_CHK=`ping -c 1 -w 4 $WAN_HOST | grep received | cut -d ' ' -f4`
	WAN_LED_CHK=`cat $WAN_LED`
	LAN_LED_CHK=`cat $LAN_LED`

	# Check Wan Connection
	if [ $WAN_CHK == 0 ] ; then
		if [ $WAN_LED_CHK == 1 ]; then
			echo 0 > $WAN_LED
		fi
	else
		if [ $WAN_LED_CHK == 0 ]; then
			echo 1 > $WAN_LED
		fi
	fi
	# Check Lan Connection
	if [ $LAN_CHK == 0 ] ; then
		if [ $LAN_LED_CHK == 1 ]; then
			echo 0 > $LAN_LED
		fi
	else
		if [ $LAN_LED_CHK == 0 ]; then
			echo 1 > $LAN_LED
		fi
	fi
	sleep 2
done

Neat little script, thanks! this will be handy for squeezing all the juice we can out our pineapples :D, would be cool if this could also be a module with auto start, lets face it we dont really need to see and of the leds when we are, "pen testing" lol
