ttdnsd is a small dns resolver for TOR which I wrote during the last two weeks. It basically bridges DNS from UDP to TCP to allow DNS requests using the TOR network. I know that there are other solutions for doing DNS over TOR but non of the solutions I know about are usable on small hardware like a router that runs OpenWRT. ttdnsd is made to run on this kind of hardware (about 600 lines of C).
Feel invited to comment and report bugs.
So now that I kicked out ttdnsd I can dedicate my weekend to my new toy (the N800) ;-)
