3. Task Set 2: Writing Programs to Sniff and Spoof Packets Task 2.1: Writing Packet Sniffing Program Sniffer programs can be easily written using the pcap library. With pcap, the task of sniffers becomes invoking a simple sequence of procedures in the pcap library. At the end of the sequence, packets will be put in buffer for further processing as soon as they are captured. All the details of packet capturing are handled by the pcap library The SEED book Computer Security: A Hands-on Approach provides a sample code in Chapter 12, showing how to write a simple sniffer program using pcap. We include the sample code in the following (see the book for detailed explanation) t include <pcap.h> #include <stdio.h> This function will be invoked by pcap for each captured packet We can process each packet inside the function void got_packet(u_char args, const struct pcap_pkthdr *header, const u_char packet) printf(Got a packet ); int main() This project is based on SEED labs by Wenliang Du, Syracuse University pcap_t *handle; char errbuf[PCAP_ERRBUF_SIZE]; struct bpf_program fp; char filter_exp[]-ip proto icmp; bpf_u_int32 net; // Step 1: Open live pcap session on NIC with name eth3 // Students needs to change eth3 to the name // found on their own machines (using ifconfig) handle = pcap-open-live ( eth3, BUFSIZ, 1, 1000, errbuf); // Step 2: Compile filter_exp into BPF psuedo-code pcap compile(handle, &fp, filter_exp, e, net) pcap_setfilter(handle, &fp); // Step 3: Capture packets pcap_loop (handle, -1, got_packet, NULL); pcap_close (handle); //Close the handle return 0; // Note: dont forget to add-1pcap to the compilation command. // For example: gcc -o sniff sniff.c -1pcap Tim Carstens has also written a tutorial on how to use pcap library to write a sniffer program The tutorial is available at http://www.tcpdump.org/pcap.htm.

Task 2.1A: Understanding How a Sniffer Works. In this task, students need to write a sniffer program to print out the source and destination IP addresses of each captured packet. Students should provide screenshots as evidences to show that their sniffer pro-gram can run successfully and produces expected results. In addition, please answer the following questions: Question 1. Please use your own words to describe the sequence of the library calls that are essential for sniffer programs. This is meant to be a summary, not detailed explanation like the one in the tutorial or book. Question 2. Why do you need the root privilege to run a sniffer program? Where does the program fail if it is executed without the root privilege? Quesiton 3. Please turn on and turn off the promiscuous mode in your sniffer program. Can you demonstrate the difference when this mode is on and off? Please describe how you can demonstrate this Task 2.1B: Writing Filters. Please write filter expressions for your sniffer program to capture each of the followings. You can find online manuals for pcap filters. In your project reports, you need to include screenshots to show the results after applying each of these filters. Capture the ICMP packets between two specific hosts. Capture the TCP packets with a destination port number in the range from 10 to 100. This project is based on SEED labs by Wenliang Du, Syracuse University. Task 2.1C: Sniffing Passwords. Please show how you can use your sniffer program to capture the pass-word when somebody is using telnet on the network that you are monitoring. You may need to modify your sniffer code to print out the data part of a captured TCP packet (telnet uses TCP). I is acceptable if you print out the entire data part, and then manually mark where the password (or part of it) is

INTRODUCTION TO PROJECT MANAGEMENT ASSIGNEMENT

Lucy is the project manager for MySportWear Company. Her project is to lead a team to develop a web-based application that allows customers to visit the corporate website and search for shoes, clothing and bags based on several factors such as size, style, color, price and brand. Throughout the project, Lucy has periodically, tested the cumulative work to see how the project is progressing. With just a few days to the project date, the application developers report that the project is complete, and the website is ready for users.

Of course, Lucy wants to experience the application before the management and the others see the results. Lucy open the website and successfully complete a few searches. She then discovers that she cannot search for a combination of factors for each item such as size, colors and brands.

Based on the scenario above:

  1. Develop an action plan for Lucy to do first to rectify the problem. Justify your answer. [10 Marks]

  1. Outline what Lucy could have done earlier in the project to avoid this problem. Discuss your answer [10 Marks]

  1. Propose what should Lucy do if the developers report that the rework can be done but it may take two weeks to complete. Justify your answer. [10 Marks]

  1. Recommend what Lucy can report to the management about the project. Elaborate your answer. [10 Marks]

1. In a turbo jet engine, the momentum of the gases leaving the nozzle produces the propulsive force. The enthalpy and velocity of the gases at the nozzle entrance are 1200 kJ/kg and 200 m/s respectively. The enthalpy of the gas at exit is 900 kJ/kg. If the heat loss from the nozzle is negligible, determine the velocity of the gas jet at exit from the nozzle.

2. For question 1, if the diameter of the nozzle at exit is 500 mm, find the mass flow rate of gas. The gas density at the nozzle inlet and exit are 0.81 kg/m3 and 0.39 kg/m3 respectively. Also determine the diameter of the nozzle at the inlet.
