    I am not sure how to tie this into my current code could you provide an example your help is very much appreciated. I am assuming I regex to the source address assign this variable a scalar value such as $flag. I am not sure how to check whether the source or dst address has already printed. It will be one or the other as well most of the time source

    thanks in advanced
