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

[Tarun Siripurapu <starunj@xxxxxxxxx>]

Hi,

I do not have access to backend cabling neither do I want to do
anything bad or illegal. I am on a campus network and want to see the
google search queries within my subnet. I heard that it was possible
that I can view all packets from any machine that is not separated
from my machine by a bridge / router. I am not trying to do anything
bad like sniff people's passwords - I only want to view unencrypted
search queries.

Basically, I want to create a type of a local google zeitgeist like:

http://www.google.com/press/zeitgeist.html

within my subnet.

The example setups shown http://wiki.ethereal.com/CaptureSetup do not
describe a topology where I am just a node on the router but want to
capture stuff all nodes. Is it possible at all?

Thanks for your time and help,
Tarun
