But a node's freedom to arbitrarily change the HTL of any search passing through it is an important part of the protocol. Not least because it would be difficult to prevent nodes from doing it anyway, and if you can't eliminate cancer nodes from the network, you can just re-define their behavior as non-cancerous. But also, this freedom to arbitrarily alter of HTL is a central part of Freenet's plausible deniability doctrine. Requesting from a node with HTL 1 doesn't indicate the presence of data on the node, because the node might have upped the search's HTL and passed it on. Furthermore, if the HTL of a request actually means something, then the network becomes more vulnerable to traffic analysis. Allowing nodes to arbitrarily change HTL ensures that all the meta-information in a packet is potentially untrustworthy to someone wishing to map out the network or its behavior based on this information. --RS _______________________________________________ Tech mailing list [EMAIL PROTECTED] http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/tech
