Use
Wireshark to Sniff Traffic
1. Download and install the latest stable version of Wireshark .
2. Click on the Capture menu and then select interfaces.
3. Click the Start button next to the interface that shows packets being
sent and
received.
If you have multiple interfaces with packet activity, choose one of them—
preferably
the interface with the most activity.
4. Click on a packet to analyze that single packet.
The detailed headers will be displayed
beneath
the packet capture screen.
5. Expand each header (IP, TCP) of a packet and
identify the address information.
This
exercise will provide much more network traffic if performed on a hub rather
than a
switch.
A wireless network can be used, as a wireless LAN is a shared network segment
similar to how a hub
operates.
