Hi All, I'm quite new to linux world. I've a very awkard question for you. That is: I'm writting an user process, where I need all outgoing IP packets to be blocked and captured. First, is it really possible? If yes, how? I don't want to make any kernel source code changes. A wild guess: by configuration changes, is it possible to make IP process write on to a particular FD which I can read when I require?
