Chipps Ph.D.Ģ9 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ8 Copyright 2007-2010 Kenneth M. Statistics The data rate can be shown Statistics – Summary Average Mbit per second for example Copyright Kenneth M. Chipps Ph.D.Ģ7 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ6 Copyright 2007-2010 Kenneth M. Statistics Wireshark can also show some statistics about the network For example to see the packets per second select Statistics – IO Graphs Copyright Kenneth M. Chipps Ph.D.Ģ5 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ4 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ3 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ2 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ1 Copyright 2007-2010 Kenneth M. Chipps Ph.D.Ģ0 Copyright 2007-2010 Kenneth M. To Capture Frames Let’s capture some frames now Select Capture Interfaces Click Start beside the interface that is showing activity Copyright Kenneth M. Chipps Ph.D.ġ9 Copyright 2007-2010 Kenneth M. The Application Layer Copyright Kenneth M. Chipps Ph.D.ġ8 Copyright 2007-2010 Kenneth M. Chipps Ph.D.ġ7 Copyright 2007-2010 Kenneth M. Chipps Ph.D.ġ6 Copyright 2007-2010 Kenneth M. Chipps Ph.D.ġ5 Copyright 2007-2010 Kenneth M. The Layers Each of these layers can be expanded to see what is inside of them For example Copyright Kenneth M. Chipps Ph.D.ġ4 Copyright 2007-2010 Kenneth M. The Layers The frame shown in detail below All the layers in this frame The contents in hex The contents in ASCII The contents of the selected layer Copyright Kenneth M. Chipps Ph.D.ġ3 Copyright 2007-2010 Kenneth M. The Layers Let’s look more closely at the layers in one of the frames shown above Copyright Kenneth M. Chipps Ph.D.ġ2 Copyright 2007-2010 Kenneth M. Chipps Ph.D.ġ1 Copyright 2007-2010 Kenneth M. The Layers As you will recall from the OSI model there are several layers that each do different functions that are part of the captured frame This is also true of the TCP/IP model which all current networks use It is divided up into these layers Copyright Kenneth M. Chipps Ph.D.ġ0 Copyright 2007-2010 Kenneth M. Wireshark The frames that were captured The layers in the currently selected frame The contents of the current layer in hex and ASCII Copyright Kenneth M. Chipps Ph.D.ĩ Copyright 2007-2010 Kenneth M. Wireshark Let’s see what now appears Copyright Kenneth M. Chipps Ph.D.Ĩ Copyright 2007-2010 Kenneth M. Chipps Ph.D.ħ Copyright 2007-2010 Kenneth M. Wireshark Not very interesting is it It is of more interest after it has captured a frame or two For example Copyright Kenneth M. Chipps Ph.D.Ħ Copyright 2007-2010 Kenneth M. Chipps Ph.D.ĥ Copyright 2007-2010 Kenneth M. Wireshark, once called Ethereal, is an open source network analyzer It looks like this Copyright Kenneth M. They carry the people and cargo in the case of a highway By capturing and examining these frames we can see exactly what is happening on the network Then when the network stops working as we expect, we can use this same tool to determine why it is not working Copyright Kenneth M. Chipps Ph.D.Ī protocol analyzer, such as Wireshark, is used to copy frames off of an active network These frames are like the cars on the highway They are the reason for the highway or network These frames carry the information in the case of a network Copyright Kenneth M.
