UDP Client-Server Implementation

This project implements a simple UDP Client-Server communication system using C++ and Winsock.

Features

• UDP Communication: The communication between the client and server is done using UDP (User Datagram Protocol), providing a lightweight and connectionless communication mechanism.

• Threading: Both the client and server utilize multithreading to handle sending and receiving messages concurrently. This allows for simultaneous communication without blocking.

• Logging: The server logs all received messages, including timestamps and client IP addresses, to a log file located in the logs directory. This provides a record of communication for debugging and analysis purposes.

• Timestamping: The system includes a function to generate timestamps in the format "dd-mm-yyyy_HH-MM-SS", which are used for logging purposes.

Usage

Server: It will listen for incoming UDP messages on port 54000 and log them to a file. Client: It sends messages to the server on localhost (127.0.0.1) port 54000.

Build Instructions

• The project is developed using Visual Studio with the Winsock library linked (ws2_32.lib). You can compile the code using Visual Studio or any other IDE supporting C++ with Winsock (justdo it in separate projects).

Dependencies

• WS2tcpip.h: Header file providing Winsock API for Windows Sockets programming.
• filesystem: C++17 feature used for creating directories to store log files.
• thread, mutex: C++ standard library features for multithreading support.

Notes

• VERY heavily inspired by this tutorial.
• This implementation is intended for educational purposes and may not be suitable for production environments without further enhancements and security considerations. (I will get to it eventually.)
• Network programming is definitely more interesting than expected...
