Instruction:Wireshark is a free network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Ethereal has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session. Wireshark is available for Windows (http://www.wireshark.org/). You want to download the Windows installer 32 bit version (first option in the download list). I uploaded a recent version package in the folder too for your convenience. Assignment:After installing Wireshark, 1.launch the application 2.If you have both wired and wireless connection on your computer, you need to select on interface for capturing. 3.Allow Wireshark to run for about 60 seconds before press down the stop button. During this period, try to use your browser to search a web page or login your UHV web email to generate enough packets for later examination. You also want to launch a DOS prompt and run programs like ping and nslookup. If you have another computer in your place, have that computer running programs like ping, nslookup, etc. too. 4.Inspect the results. 5.Pull down the Statistics menus and select Summary, Protocol Hierarchy Statistics as well as others to do post-assignment analysis. Report: 1)Submit answers to the following questions based on the reports you generated. How many packets were captured? How many packets were dropped [look in the summary]? Describe the different types of protocols captured and the different levels of communications (use the different tabs inConversations). Were there any unexpected "conversations"? (hint: if you have another computer ping your computer, then you should be able to see this conversation under IPv4 tab; if you use nslookup, you should be able to see conversation under UDPtab; for any Web browsing activity, you should see conversations under TCP tab.) Which device(s) did your computer "talk" to the most? (hints: are you using router?) Which are the most frequent type of packets captured? Was the traffic constant [look at the IO Graph]? Describe several other uses of Ethereal you explored?
