I am trying to generate a GPG key, and I cannot generate enough entropy. So I installed rng-tools
and tried following these instructions: https://serverfault.com/questions/214605/gpg-not-enough-entropy
When I am logged in as root, and try to run rngd -r /dev/urandom
I get the following error: can't open /dev/random: Permission denied
I find this disturbing as I am root.
This is Ubuntu on a virtual server (via Parallels I believe.)
