Re: [privoxy-users] Reverse DNS Lookups?

TOR questions should be directed to the onion router mailing list - I've added
them to the cc: list

grc.com is good enough to tell if you've got things configured correctly, but
it isn't a very good test site.  I just tried it & they didn't display my real
IP adddress.  A better test site is
http://metasploit.com/research/misc/decloak/  that one can find my real IP
address if I leave enough plugins enabled.

Are you sure that you've got Firefox configured correctly?  Click on
Tools/Options and then Advanced/Network/Settings.  Make sure "Manual Proxy
Configuration" is selected.  Enter port 8118 for the http host & port
and make sure that "Use this proxy server for all protocols" is checked.

Are you sure that you've got Privoxy configured correctly?  Somewhere in the
main config file you need to have a line like this
  forward-socks4a  /  .
to tell Privoxy to forward all traffic to TOR

I think your browser and/or privoxy is not configured correctly.  Once you
straighten out the configuration issues then you get to deal with the problem
of plug-ins leaking info.  I don't know where the Tor group is with that.. but
it seems like the only resolution is to disable all plugins.  I've been reading
things about running your browser session inside a virtual machine that sends
all of the network traffic through Tor but I don't if or how well that works.

Hope this helps..
