4.1. I installed Tor and Privoxy but it's not working.
Are you sure Tor and Privoxy are both running? If you're using Vidalia, you may have to click on the onion and select "Start" to launch Tor.
Did you configure your web browser to http proxy to port 8118? Most people should do this simply by installing Torbutton and making sure it says "Tor enabled" at the bottom.
Check your Tor logs
. Do they give you any hints about what's going wrong?
Check your system clock. If it's more than a few hours off, Tor will refuse to build circuits. For XP users, synchronize your clock under the clock -> Internet time tab. In addition, correct the day and date under the 'Date & Time' Tab.
Is your Internet connection firewalled
, or do you normally need to use a proxy
? Are you running programs like Norton Internet Security that block certain connections, even though you don't realize they do?
If you installed Privoxy yourself (not from a bundle), did you edit the Privoxy config file as described? Did you remember to put the "." at the end of the Privoxy config line? Did you accidentally comment the config line out? Did you restart Privoxy after this change?
For Red Hat Linux and related systems, do you have SELinux enabled? If so, it might be preventing Privoxy from talking to Tor. We also run across BSD users periodically who have local firewall rules that prevent some connections to localhost.
When it's working, Tor should report that it 'has successfully opened a circuit. Looks like client functionality is working.'
Specifically, look at the part about RedHat and SELinux.
