Asuswrt Official - RT-AC68U - Turn Off LEDS - Cron Job

[shauno100]

Hi,

I was wondering if it is possible to turn off all of the LEDS on the AC68U using cron jobs in the Asuswrt stock firmware for AC68U?

I know it can be done on Asuswrt Merlin (stealthmode) and Shibbys Tomato via a modified script but i was wondering if i could run some commands via a cron job to turn off the LEDS at a set time and back on in the official firmware.

Thanks in advance

Shaun

i managed to get it working although it was alot of stuffing around using the below if anyone was interested.

TURN OFF LEDS
led_ctrl 0 0 #Turn off Power LED
wl -i eth1 leddc 1 #Turn off 2.4Ghz LED
wl -i eth2 leddc 1 #Turn off 5Ghz LED
et robowr 0x00 0x1a 0x1e0 #Ethernet LEDS off
et robowr 0x00 0x18 0x1e0 #Ethernet LEDS off
led_ctrl 10 0 #Turn off Rear ASUS Logo LED
led_ctrl 9 0 #Cant remember exactly if this was the number i used but it successfully turned off USB LED

TURN ON LEDS
led_ctrl 0 1 #Turn on Power LED
wl -i eth1 leddc 0 #Turn on 2.4Ghz LED
wl -i eth2 leddc 0 #Turn on 5Ghz LED
et robowr 0x00 0x18 0x1ff #Ethernet LEDS on
et robowr 0x00 0x1a 0x1ff #Ethernet LEDS on
led_ctrl 10 1 #Turn on Rear ASUS Logo LED

I put these into 2 scripts LEDSOFF.sh and LEDSON.sh and placed them into /jffs/scripts and set them as executable

I then created 2 cron jobs and scheduled the above scripts to run at specified times each day. Everything worked, only thing that didn't was the cron jobs were wiped after a reboot as the stock firmware clears the contents of /var/spool/cron/crontabs

I then came across https://www.securityforrealpeople.com/2015/08/cron-on-asus.html which mentions a USB mount feature of the stock firmware that you can run commands/scripts from, so i set it to copy a file containing the 2 cron jobs from /jffs to /var/spool/cron/crontabs which effectively reactivated the 2 cron jobs upon reboot. Only downpoint is the USB flash drive needs to be plugged in at all times for this to work.


Cheers
