Demonstrate data transfer using TCP /UDP/MDNS and DNS packets (advance networking)

Assignment

Task 1: Install Wireshark (https://www.wireshark.org/#download) by downloading the appropriate package.

Task 2: Capture TCP packets using Wireshark to demonstrate 3-way handshaking. Submit a screenshot containing SYN, SYN+ACK, and ACK packets information. Also, provide the following information based on the packets that you capture:

First Packet (SYN packet) from Client to Server:

1. Source IP address:
2. Destination IP address:
3. Source Port Number:
4. Destination Port Number:
5. Sequence Number:
6. Acknowledgment Number:
7. Flags:
   1. Which flag bit(s) is/are set:
8. Window Size:
9. Checksum:

Second Packet (SYN + ACK packet) from Server to Client:

1. Source IP address:
2. Destination IP address:
3. Source Port Number:
4. Destination Port Number:
5. Sequence Number:
6. Acknowledgment Number:
7. Flags:
   1. Which flag bit(s) is/are set:
8. Window Size:
9. Checksum:

Third Packet (ACK packet) from Client to Server:

1. Source IP address:
2. Destination IP address:
3. Source Port Number:
4. Destination Port Number:
5. Sequence Number:
6. Acknowledgment Number:
7. Flags:
   1. Which flag bit(s) is/are set:
8. Window Size:
9. Checksum:

Task 3: Capture UDP packets using Wireshark to demonstrate data transfer using UDP. Submit a screenshot. Also, provide the following information based on the packets that you capture:

1. Source IP address:
2. Destination IP address:
3. Source Port Number:
4. Destination Port Number:
5. Length:
6. Checksum:

Task 4 (Optional for bonus points): Capture MDNS packets using Wireshark to demonstrate data transfer. Submit a screenshot.

Task 5 (Optional for bonus points): run DNS resolver script to know the IP address of your undergraduate institute’s host name. Submit the code as well as the output as a screenshot or as a separate file.
