Re: [Ethereal-users] Sniff all packets in a subnet

["Tom Greaser" <tgreaser@xxxxxxxxxxx>]

1: Guessing you tried to see what "google" searches people were doing..
and since you didnt see any.. and your traffic is getting to the
internet.
I will BET that your on a switch that is connected to a router..

2: One more time.. This is totaly possilbe to sniff an entire subnet!!!!
How.. not telling you exactly.. but ive done it a hundred times with my
linux / ethereal box
(plus other GPL stuff)

Hi, 
 
How are you confident that I am behind a switch and not a router? Is
