CNT 4704: Analysis of Computer Communication Networks
Fall 2012
Lab assignment 1: Getting familiar with Wireshark
software.
(Assigned Sept. 4th, Due date: Sept. 11th midnight via
WebCourse)
In this simple assignment, you will install Wireshark software on your own desktop/laptop computer and get to know the basic procedure on how to use it to check network traffic.
Please go to: http://www.wireshark.org/ to download the software.
I want you to follow what I have demonstrated in class to capture the http traffic when you check any one website. For the example of the procedure, please see this lab assignment from Prof. Jim Kurose.
Then answer the following questions:
1. What is the IP address of your computer and the IP address of the website you connected? Did the web server keep the connection open? Did the server run HTTP 1.0 or 1.1?
2. How long did it take from when the
HTTP GET message was sent until the HTTP OK reply was received?
(notes: there could be many http get and http ok packets during
the packet capturing. Make sure you obtain the right pair of get
and ok messages. The http get message should be the first
message sent from your computer to the designation web server)
3. Save the HTTP GET message and the HTTP OK message. For the first HTTP GET message, right-click mouse on the selected packet. On the pop-up window, select "Copy"=>"Summary (Text)", which will save this HTTP GET message into a plaintext file. Do this also for the corresponding HTTP OK message. Then copy the content of both plain-text file into the end of your lab report.
After finishing your lab report, submit it through Webcourse@UCF.
