Entropy sources for rngd

[Brian Mearns]

Sorry, I know this is only somewhat on topic: if someone can suggest
an appropriate mailing-list or news group, that'd be great.

I want to use rngd to increase my entropy pool for use with GnuPG, but
I don't have a hardware random device. I've seen a lot of references
to using /dev/urandom as the input source for rngd, which claim that
rngd's randomness test is sufficient for ensuring that the entropy
pool remains random. But there's something that really doesn't sit
well about that for me. Can anyone offer informed insight on this?

Thanks,
-Brian
