Redirect output to urandom and link random to urandom

[alexandre]

Thanks Paul

I was milead i think by the led on the onerng then. when i launch the classic onerng.sh script  on default /dev/random  and then i test with cat /dev/urandom > /dev/null ; the led stay bright. 

However when launching rngd -o /dev/urandom ; then the leds is always dim. I tought this was the result of all the programs (lsof | grep urandom) that where using it .

Can you explain this behavior?
