Can sniffers act in remote networks?

[Bruno Negr�o]

Hy all, Could someone tell me if sniffers can hear remote connections? In my conception, sniffers just can hear the traffic where they are directly connected. Is it right?   Thank you -------------------------------------------------  -- Bruno Negr�o -- Suporte  -- Plugway Acesso Internet Ltda.  -- (31)34812311  -- [EMAIL PROTECTED]
