Quote from: jase00 on May 27, 2013, 02:56 pmI'm familiar with DNS, HTTP URLS etc etc... not so much with Tor but I do appreciate your assistance.My question wasn't very well written. I meant if your using the Tor browser bundle for e.g and for whatever reason Tor isn't functioning properly.. couldn't your DNS request go out via your normal DNS servers (which could perhaps be your ISP's?) and then I was thinking shouldn't iptables block DNS requests, in case that did happen ?I imagine the DNS is only pushed through Tor for resolution because you tell the browser to use Tor as a proxy ? The same way as if you use a proxy at work or whatever and all DNS that's not excluded in a proxy.pac is sent through to the proxy to resolve ?Ohhh, I see what you're asking. Apologies if I was patronizing or anything. No, it still won't leak even if Tor isn't currently running: Firefox just fails if the proxy you set is unacceptable. The Tor browser bundle is a version of Firefox. Though I can't be positive: I know it just fails, but now that I think about it, I never actually checked whether it goes off and does address resolution anyway... I don't think it's that silly or anything, but I've never checked personally.
