You are referring to the entropy pool used for /dev/random and crypto operations ?
You could setup a video capture card or radio tuner card, tune it into a good noise source, and arrange for the bit stream to get written to /dev/random
Yes, but then you're also introducing a way for an external attacker to transmit data that can be mixed into your entropy pool. While certainly a cool hack, I don't think anything like this would be safe for cryptographic use. </two cents> Cheers, jof
