Wireshark Lab: Ethernet and ARP v6.01 Supplement to Computer Networking: A Top-Down Approach, 6th ed., J.F. Kurose and K.W. Ross “Tell me and I forget. Show me and I remember. Involve me and I understand.” Chinese proverb © 2005-21012, J.F Kurose and K.W. Ross, All Rights Reserved In this lab, we’ll investigate the Ethernet protocol and the ARP protocol. Before beginning this lab, you’ll probably want to review sections 5.4.1 (link-layer addressing and ARP) and 5.4.2 (Ethernet) in the text1. RFC 826 (ftp://ftp.rfc-editor.org/innotes/std/std37.txt) contains the gory details of the ARP protocol, which is used by an IP device to determine the IP address of a remote interface whose Ethernet address is known. 1. Capturing and analyzing Ethernet frames Let’s begin by capturing a set of Ethernet frames to study. Do the following2: • First, make sure your browser’s cache is empty. To do this under Mozilla Firefox V3, select Tools->Clear Recent History and check the box for Cache. For Internet Explorer, select Tools->Internet Options->Delete Files. Start up the Wireshark packet sniffer • Enter the following URL into your browser http://gaia.cs.umass.edu/wireshark-labs/HTTP-ethereal-lab-file3.html Your browser should display the rather lengthy US Bill of Rights. 1 References to figures and sections are for the 6th edition of our text, Computer Networks, A Top-down Approach, 6th ed., J.F. Kurose and K.W. Ross, Addison-Wesley/Pearson, 2012. 2 If you are unable to run Wireshark live on a computer, you can download the zip file http://gaia.cs.umass.edu/wireshark-labs/wireshark-traces.zip and extract the file ethernet--ethereal-trace-1. The traces in this zip file were collected by Wireshark running on one of the author’s computers, while performing the steps indicated in the Wireshark lab. Once you have downloaded the trace, you can load it into Wireshark and view the trace using the File pull down menu, choosing Open, and then selecting the ethernet-ethereal-trace-1 trace file....
