["AMEAUME, ALAIN (ALAIN)** CTR **" <alain.ameaume@xxxxxxxxxxxxxxxxxx>]

Thanks a lot for the info: i decide to insert a hub to simplify my cx -> so that I see all traffic which are broadcasted over any ports.

Still asking who to do if i'm very far from the hostA & B? and connected myself on a remote subnet ? maybe using the remote mirroring ? but for that i need user account to activate mirror session over switches ! ?

Anyhow, thanks all for your help.

There are lots of options for doing this, you might want to start by looking at this http://wiki.wireshark.org/CaptureSetup/Ethernet#Switched_Ethernet

You could do the route option but that seems to add a lot of complexity and will change your packet flow which may work against why you are capturing in the first place.

Hope that helps

Subject: [Wireshark-users] How to use a "wireshark sniffer PC" to capture ftp flows between 2 terminals located on 2 # sub-networks ?

Hi users,

I'm interesting to know how to insert my PC laptop with wireshark as a" PC sniffer" between 2 terminals to capture ftp flows between them:

terminal "A" in sub-network x.y.A.1
terminal "B" in sub-network x.y.B.1
my PC laptop "C" on sub-network x.y.A.2 or x.y.B.2

using this configuration, I do not need to install wireshark on A & B !

I suppose that on "A" terminal I need to create a route from A.1 to B.1 passing thru "C", the same relatively to "B", then I will need also to declare on my laptop "C" a kind of "gateway" function to re-route the ftp flow, after capture, to its original destination  Is it what we call the NAT function on "C": and how to do it on the "C" laptop windows xp sp3 ?

Thanks for your help.

Alain
