Hello Mike, My feeling is that you are both right, the one who asked you how it is possible and you. It is not possible when the attacker is not on the same virtual path (lets say path instead network) but the attacker has -as the wired-article describes- the possibility to bring himself on the path for instance by modifying the route (BGP). As you see, the answer to your question is no. You cannot pick up any information from a flow you are not connected to somehow. The webserver doesnt see all the information, it sees all information delivered to it once he is a part of the virtual path the information took. -- Best regards, Adam Pal Tuesday, November 11, 2008, 2:16:08 AM, you wrote: <==============Original message text=============== m> Hi, there.
