Re: I can't sniff my LAN

Port mirroring only applies to a switch. And not all switches  
(especially the cheaper, unmanaged ones) can handle port mirroring.   
All traffic in a hub is available to all ports.  You've got to figure  
out what you've got.  And that link is in Brazilian Portuguese only-- 
maybe a fellow Brazilian or Portuguese-speaking subscriber to this  
list might be able to tell us what it says.
