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 or strace -o strace.txt sh -c 'cat rnd.bin > /dev/urandom' It looked like from the strace that reading worked, but writing didn't.
