Your MAC, being an OSI Layer 2 feature, is not propagated beyond the first router (unless you use IPv6, which can embed MAC information within the /64 local part of the address -- Tor doesn't do IPv6 yet) or malware on your system sends that information). -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
