| This is quick and dirty explanation of a sample capture file. It is a capture of an ARP request injection. To keep things simple, I have only included three rounds. | This is quick and dirty explanation of a sample capture file. It is a capture of an ARP request injection.

| - | To view the capture, use [[http://www.wireshark.org/|Wireshark]] to open it then "View" then "Expand All". This shows all the sections and fields expanded. You will need to scroll through the fields for each packet to locate the ones mentioned.

| Notice the the initialization vector number (IEEE 802.11 -> WEP Parameters) is the same on each. This is because we are injecting the same packet over and over. | Notice the the initialization vector number (IEEE 802.11 -> WEP Parameters) is the same on each.
