Yes, that is the question being asked. Whether or not any given relay can tell if a given connection being made to it is in fact as the first of the three relays (entry node) that a client has chosen for its circuit. ie: detecting with exclusive certainty the parenthesized relationship below. (client > EntryNodeRelay) > relay > relay > [to internet/hiddenservice] And I presume that once the entry knows it is being used as such by a client, it can be instrumented with code to follow all of that clients network activity (time/size/etc) resulting from that particular relationship? And even if the client is also acting as a relay, by further discriminating in its following of such activity between activity which is a result of the entry relationship, and the activity of the plain relay relationship where a third party is serving as the entry node? _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
