Re: PirateBox is setup and inactive but the USB key is always blinking

I don't know how to install a additional software tool to monitor the softwares disk activity, but i have find this way to check the general disk activity : cat /sys/block/sda/stat ( [www.kernel.org] ).

Result of my test :

# swapoff --all

After 20 minutes (the LED blinking has no changed) :

The incredible thing is that it seems there was no disk activity, however the LED has not stop blinking.

After browsing (for 15 sec) the PirateBox in WIFI with a smartphone (the blinking was a bit slower) :
