Sniffers can only accurately monitor traffic on their own collision domain. To sniff on a switch you need to create a monitor port, which will allow the switch to flood traffic between this port and the selected port(s) which are your target(s).
Some sniffers, NAI's Sniffer Pro for example, sell adapters which allow you to monitor traffic directly on different media ie, ATM, Frame, etc. You can also get sniffers with remote agents which allow the capture/monitor to take place on remote segments, then send the data back to your machine for inspection.

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] _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
