Tor

Présentation
Tor est un logiciel libre et un réseau ouvert qui vous aide à vous défendre contre une forme de surveillance qui menace les libertés individuelles et la vie privée, les activités et relations professionnelles confidentielles, et la sécurité d'État connue sous le nom d'analyse de trafic, ...
  • Empêche quiconque de repérer votre localisation ou vos habitudes de navigation
  • Utile pour les navigateurs web, les clients de messagerie instantanée, les connexions à distance, et encore plus
  • Libre et open source pour Windows, Mac, GNU/Linux / Unix, et Android



Tor vous protège en faisant transiter vos communications au sein d'un réseau distribué de relais hébergés par des volontaires partout dans le monde : il empêche quiconque observant votre connexion Internet de savoir quels sites vous visitez, et il empêche le site que vous visitez de savoir où vous vous trouvez. Tor fonctionne avec bon nombre d'applications existantes, y compris les navigateurs web, les clients de messagerie instantanée, les connexions à distance, et autres applications basées sur le protocole TCP.

Bonjour,

J'ai testé le programme ci-dessous pour le surf anonyme.
Chacune de ces trois méthodes offre la possibilité de fonctionner en mode classique TCP/IP et en mode TOR pour l'anonymat :

new NetlibHttpUsageExamplesRemoteTest().simple_HTTP_GET_request_with_HttpUtil(); 
new NetlibHttpUsageExamplesRemoteTest().execute_HTTP_GET_with_Adapter_URL(); 
new NetlibHttpUsageExamplesRemoteTest().execute_HTTP_GET_with_Adapter_URL_with_global_reconfiguration_of_class_URL();
En mode TCP/IP, tout marche à merveille : les trois méthodes extraient le code HTML des sites concernés tout en affichant mon adresse IP qui est fixe.

En mode TOR (pour l'anonymat), rien ne va plus, le programme tourne en rond sans jamais réussir à capter aucun flux.

// classic:   TcpipNetLayer with NetLayerIDs.TCPIP (--> HTTP over plain TCP/IP) 
// anonymous: TorNetLayer with NetLayerIDs.TOR (--> HTTP over TCP/IP over Tor network) 
//NetLayer lowerNetLayer = NetFactory.getInstance().getNetLayerById(NetLayerIDs.TOR);  
NetLayer lowerNetLayer = NetFactory.getInstance().getNetLayerById(NetLayerIDs.TCPIP);
Merci d'avance pour votre éclairage
