Hi Sandy, if you do a search on the Debian repositories (i.e. package.debian.org ), you'll notice that haveged ( http://packages.debian.org/squeeze-backports/haveged ) is in the squeeze-backports repository. I installed the armel build from there onto my Squeeze installation on my Linksys NSLU2 and QNAP TS-109 machines. As I reported, haveged produces plenty of entropy on these machines, which when tested with ENT ( http://packages.debian.org/squeeze/ent ), the entropy appears to be of sufficient quality. In fact, the amount of entropy generated is so much that I don't think timer entropy daemon or random sound are interesting projects to go after. I haven't tested turbid, but it needs to generate an order of magnitude of entropy more than randomsound before it'll be a contender for entropy generation in my opinion. And I'm personally not very fond of having an active microphone hooked up in the room where my server is.
