There are more ways then one to capture the lan bus. This tutorial will use [wireshark]

Here are some reasons why:

In the example below there is only one Lan card installed.

Press start to start the capture, normally the default options are correct.

Perform the item you want to have logged, and stop the capture. This can be done by:

Make sure that the option All packets is selected.

Save the file, put it in a zip file so the total file size will decrease.
