I heard of the Tor browser from friend and downloaded it.

I'm curious to see what exists on the .onion sites but all the ones I tried shows me an error message telling me that there is a connection problem.

I wonder if I have properly configure Tor and if not, how can I make it correctly?

    Here is the address of the DuckDuckGo hidden service.<br/> I've confirmed that it's working. If you can't connect to this then it's likely you have a configuration issue.<br/> If you download and use the Tor browser bundle you shouldn't have any configuration issues. Here is a link to a page containing links to other .onion sites. While it contains active links I can't guarantee that it's trustable.

  • I've configured firefox to use my proxies dns when using tor. The new firefox versions his is done in the configuration. Without it , your browser attempt to resolve the hidden service address with your normal DNS (isp's or googles) and that will not happen.

    In my experience it just depends on the site; some work some don't. This is probably do to the site no longer existing so just keep trying! JpR

  • Tor, if configured, will automatically run .onion links on its browser. Oct 7, 2016 at 3:40

Enable the dns function of tor. In torrc, add the line

DNSPort 53

If you use unix, you will also need to add the line

user tor

to torrc and run tor as root, because it needs to bind to port 53.

And configure your operating system to use localhost as DNS server.

There are also other ways, such as using a caching dns server.

  • Is this really necessary? I run the Tor Browser with the default configuration, and I can access Onion services just fine. Apr 8, 2016 at 12:55
  • Agreed with the last comment. It's likely this is just the problem of the hidden service no longer existing, as per one of the comments on the question itself. Apr 9, 2016 at 22:52
