Ah, OK, thank you.
So if I want to track the complete network traffic in my network, I need on both a running Wireshark on monitor / promiscuous mode.

Franc, you wrote:

If you want to see the (unicast) traffic between your both endpoints you only need one Wireshark instance at one of both PCs. The promiscuous mode is not necessary in this case.

If you want to see what else is on the network (like broadcasts or packets not sent to to your 'other end') you will need Wireshark at both ends when a router or any switching hub is between them.

Hi Frank,

No, your router will be behaving like a switch and will not send all packets
to all machines. Therefore you will not see the packets in this setup.

You might want to have a look on the wireshark wiki pages. Here is a good
link.

Subject: [Wireshark-users] Basic question about Wireshark


Hello,

I am just a wireshark beginner and don't know basic things. I have this
question:

When I sniff a Wireless Network, will I be able to sniff packets of the
same network but sent not wireless but by cable (LAN)?
Vice versa, when I sniff with my LAN Network adapter will I see wireless
packets in the same network?

I have a router with wireless and LAN. I have connected my laptop with
wireless and my PC with cable in the same network.
I want to see the data of each other with Wireshark. Is this possible?

Thank you for clarification.
