This directory contains the source code for key components of our project. Each file serves a specific purpose, detailed below.

1. network_dissector.c

   • Description: This file contains code for a basic network packet dissector. It interprets the contents of a raw network packet, extracting and displaying information such as the Ethernet source and destination MAC addresses, as well as the IP source and destination addresses.
   • Key Functions: Parsing Ethernet and IP headers from raw packet data.

2. tcp_calculator.c

   • Description: Implements a TCP server that receives a number from a client, calculates its square, and sends the result back. This file showcases basic network communication using the libuv library.
   • Key Functions: Handling TCP connections, reading data, and sending responses.

3. timer.c

   • Description: Demonstrates the use of timers and idle handles in libuv. This file includes a timer that counts up to a user-specified number, and an idle handle that updates the display during the counting process.
   • Key Functions: Timer initialization and callback management, idle loop handling.

To compile and run these programs, follow these steps:

1. Install libuv if not already installed.
2. Compile each file using a C compiler, e.g., gcc -o network_dissector network_dissector.c.
3. Run the compiled executable, e.g., ./network_dissector.

• libuv library for tcp_calculator.c and timer.c.
• Standard C libraries for network_dissector.c.

• network_dissector.c does not handle all possible network protocols and is meant for educational purposes.
• tcp_calculator.c requires a TCP client to interact with the server.
• timer.c uses the terminal for output, and the display updates depend on the idle handle.

Contributions to improve or extend the functionality of these programs are welcome. Please follow standard GitHub pull request procedures.
