Can you access /dev/urandom outside of ruby? It might be a simpler
check to ensure that /dev/urandom is working.
Something like to check reading:
head -c 10 /dev/urandom > rnd.bin
and then to check writing:
cat rnd.bin > /dev/urandom
strace -o strace.txt sh -c 'cat rnd.bin > /dev/urandom'
It looked like from the strace that reading worked, but writing didn't.
