aspadistra Posted October 1, 2007 Report Share Posted October 1, 2007 Sandvine's (out of net) connection kill trick -- is MUTorrent immune?Sandvine sends a counterfit packet to seeding clients making them belive that the remote connection has hung up.This Sandvine hack has revealed a fatal weakness in the protocol.Comcast has implimented this approach, but it could become widespread.A secure VPN for client to client communications could help fix the problem, for the supervisory packets (not the file segment packets).The protocol may itself need to be fixed -- but how must be subject to some debate.At least 5 solutions to this problem probably need to be found.

Firon Posted October 1, 2007 Report Share Posted October 1, 2007 The protocol can't fix it. It's a TCP-level problem (as in, it sends the RST TCP flag to both sides). Link to comment Share on other sites More sharing options...
aspadistra Posted March 9, 2008 Author Report Share Posted March 9, 2008 Technically both clients could at least ask each other if the shutdown signal is true, technically making it a protocol issue...There is naturally room for some kind of AES or crypto authentication here as well -- again protocol level...

jewelisheaven Posted March 9, 2008 Report Share Posted March 9, 2008 Given the current FCC hearings I think it's a bit premature to even discuss changing the protocol over packet injection... I'm more interested in if http://bittorrent.org/beps/bep_0008.html gets adopted and keeps network hardware from harvesting the peerlists and thereby interfering with traffic at all Link to comment Share on other sites More sharing options...
aspadistra Posted September 12, 2008 Author Report Share Posted September 12, 2008 I am for peer obstrufication being implimented as soon as reasonably possible.However, the whole BT client communications structure needs to be moved to XML -- and encrypted (and compressed) XML at that.

thelittlefire Posted September 12, 2008 Report Share Posted September 12, 2008 Yes, bloated and ... infinitely useful (aka not the best idea for massive data transfer) datatypes. :`( Not on your life.Heh, well I searched for XML on the forum and popped up this http://forum.utorrent.com/viewtopic.php?pid=321384#p321384 Link to comment Share on other sites More sharing options...
