RE: A Solution for sniffing

[<Bruce.Orcutt () alltel com>]

As sniffing is a passive act, there is no way that you can detect the act itself, unless you have access to the machine 
that's doing the possible sniffing itself.

Perhaps one of the simplest ways to ensure sniffing is made much more difficult at the least is by switching from a hub 
type network to a switched network.  In a switched environment, other users cannot see each others network streams, 
thus providing a layer of protection.  

Of course, like all techniques, this can be gotten around by various additional techniques, but it does make life more 
difficult to would be sniffers. (ie: user installs a hub via an uplink port to switched segment, and connects target's 
system and a sniffing machine to the hub.)

Hello Folks,
I think i am being sniffed by somone on my network, and i was wondering. is 
there an application to check wether i am being sniffed or not, and if i 
was, how can i fix that ?(like PGP for mail, what about other protocols) 

P.S. : Running Linux Slackware 8.1 (if that would help) 

cheers,
