Hope it was clear... Hi, Thanks for your reply. Taking from the point that IP addresses are known to your peers, I have another question. I've noticed that the hop-to-live counter is decremented according to the policy of: 1) the source node of the request, 2) the node which recently reported fail for a data request or 3) the node handling the request (usually because the node is the source of the request) Ok, so what if I modify the code for my node so that: 1) maxHTL = 1 2) decrementAtMin = false 3) disableProbabilisticHTLs = false Would this mean that my peers would not forward my message any further?

Or maybe he does not have it, and sends the packet the HE generates? I do not actually know how this will work, but anyway you will end up probing one key. You know how many of them there are? And the probability that some node has a data segment for one of them is you know... not so high=) However, this IS a security issue, and it should be tested. ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

This is because if so, this would allow me to probe my peers using my set of keys for data Your peers will sometimes pass on requests at min htl, specifically to avoid this problem. That's what the probabilistic htl thing is for. Turning off probabilistic htl only turns it off on your node; it doesn't change your peers config, obviously. So turning it off will let other people probe your store, but doesn't help you probe theirs.
