Duplicate ports ?

["Ory Segal" <ory () avnet co il>]

Hi everyone, 

I've been quietly listening to all your questions and answers - first of all keep on the good work.
second, What does the msg :"Duplicate port.." means ? 

And by the way ? has anyone noticed that the -vv doesn't really work ? or is it just me ?

                                                                                                                    Ory.
