what are the counter measures for IP spoofing in a linux box.countermeasures

By now I think you have serious problems understanding what this board is about and how you should interact with it's members. You persist in posting without interaction, and posting the same question repeatedly, nor did you answer any previous questions or react to my invitation to try and find out what problems you have with respect to a possible language barrier.

If we are not able to retrieve relevant details about the scope of what you are talking about, then in essence you are not helping us to help you, and so helping you will amount to giving generic answers, and that's not what we're after here.

Visit your past posts and answer any outstanding questions or mail me what the problem is. Be warned if you persist playing the game this way I'll be forced to take some countermeasures myself.

Since I and Tricky both answered your question below, this post will be closed. If you want to dispute my moderating decisions I invite you to take it up with me by mail.
