افتراضي رد: شرح برنامج Wireshark لسؤال الواجب


هذا السؤال
Q3. Sniffing wireless traffic using Wireshark
Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education. The software and its user guide could be downloaded from its home page (i.e., http://www.wireshark.org/). In this question, you will investigate the 802.11 wireless network protocol using this passive measurement tool. For more information on 802.11 management frame types, you can find many references as for example “Understanding 802.11 Frame Types” by Jim Geier (i.e., http://www.wi-fiplanet.com/tutorials...le.php/1447501).

Unfortunately, most of the device drivers for wireless 802.11 NICs (particularly for Windows operating systems) don’t provide the hooks to capture/copy received 802.11 frames for use in Wireshark. Therefore, we will provide you in this question a trace of captured 802.11 frames to analyze; assume in the following questions that you are using this trace. If you are able to capture 802.11 frames using your hardware settings, we encourage you to train on this software using your proper tests. An alternative solution for packet capture that you can use in your upcoming projects is to use a small USB device, AirPcap, (i.e., http://www.cacetech.com) that captures 802.11 frames and provides integrated support for Wireshark under Windows.

To start the experiment, open in Wireshark the trace Wireshark_802_11.pcap which is attached to the TMA files. You can load the trace into Wireshark using the File pull down menu, choosing Open, and then selecting the Wireshark_802_11.pcap trace file. The resulting display should look just like Figure 1.



Figure 1: Wireshark window, after opening the Wireshark_802_11.pcap file

For answering the following questions, you should look at the details of the IEEE 802.11 frame and subfields in the middle Wireshark window.


To deal with the plagiarized answers in this question, the student must make an oral demo of the software for his/her tutor showing him/her how he/she has opened the trace and manipulated the packets to find the answers provided in the submitted TMA. Then, tutor can decide to deduct (or not) part or whole of the marks awarded based on the quality of the demo.
1. Given that beacon frames are used by an 802.11 AP to advertise its existence. What are the SSIDs of the two access points that are issuing most of the beacon frames in this trace?

2. What are the intervals of time between the transmission of the beacon frames from the
linksys_ses_24086 access point? From the 30 Munroe St. access point? (Hint: this interval of time is contained in the beacon frame itself).

3. What (in hexadecimal notation) is the source MAC address on the beacon frame from 30 Munroe St?

4. What (in hexadecimal notation) is the destination MAC address on the beacon frame from 30 Munroe St?

5. What is the BSS ID of 30 Munroe St?

6. The beacon frames from the 30 Munroe St access point advertise that the access point can support four data rates and eight additional “extended supported rates.” What are these rates?

7. What is the Channel number used for WiFi communication?

8. Consider the first PROBE REQUEST and the soonest subsequent PROBE RESPONSE PAIR occurs after t = 2.0 seconds in the trace. When these frames sent and what are the sender, receiver and BSS ID MAC addresses for these frames? What is the purpose of these two types of frames
