I think I've understood a few mor things since my previous mail... I think that ns2 take into account the header, but doesn't register it in nam file, that's why it is not viewable in nam. But now my question is, how to write header length into nam file ? I've tried to write variable hdrlen_ but this variable is equal to 10128 and it's surprising because I've removed all headers exepts comon and IP, so the size of my header shoulb be less than 10128. My second question will be, how to use this stored header length into nam...
I browsed the forum and saw that only a few messages got response... Hope mine get one.
