m does not open automatically you can open Project 1: Capturing and Analyzing Packets using Wireshark here more examples of filtering commands select CaptureCapture Filters..." To stop capturing packets, select "Capture Stop" from the menu bar A nice introduction to Wireshark can be found at this YouTube video. Exercise 1: UDP & TCP (6 points) Open your web browser (e.g, Intemet Explorer), then start capturing packets using Wireshark. a) Visit www.ietforg. You should notice two DNS packets (a query and its response). Identify the IP addresses of the source and destination involved; which one is your machine's address, and which one is the DNS server's address? (1.5 points) b) What transport protocol does DNS use? (0.5 point) c) What is the IP address returned by the DNS response? Is it the same address that the following packets transmitted from your machine use as its destination address? (0.5 point) d) List TCP port numbers that your machine and web server are using? (1 point) e) Identify the messages involved in the TCP setup process along with listing their TCP flags and sequence numbers. Hint: Under Edit, select Preferences, then under Protocols, select TCP and make sure the "Relative sequence numbers and window scaling" is unchecked. (2.5 points) Wireshark will offer to install WinPcap if it is not installed already on your machine. Be sure to check the box, as WinPcap is required to capture live network data.
