The communication between Privoxy and Tor was not set up correctly in the configuration files,it is OK now.Additionaly some things in the logs were due to entrynodes and exitnodes restrict options in my torrc.Anyway I downloaded and compiled the most recent Tor which is run now from /usr/local/ when I need,and not when the computer boots(the default in debian). http://check.torproject.org tells me that everything is OK.
The question: can I use the FQDN or IP preferably, instead of nicknames,in torrc entrynodes,exclude nodes,exitnodes options?I have read something lately about the functioning of the Tor system, and it seems the directory servers/client initial dialog to determine the running nodes is protected by strong authentication,but when I access a listing of running nodes(by country,etc.) using https://stat.xenobite.eu(for example) with a webbrowser,how do I have assurance that the nicknames correspond to the real IP address? Does Tor check based on the strong authenticated listing received upon initial dialog with the directory servers the authenticity of the pairs nicknames/computers we could set up in exitnodes etc. of torrc? Thanks.
