Multi-Client Network Server

A simple TCP server implemented in C that handles basic GET and PUT commands from clients. The server can handle multiple client connections using the fork() system call for concurrent processing.

Features

• Process Management: Utilizes fork() to handle multiple clients concurrently.
• Socket Programming: Demonstrates basic TCP socket operations.
• GET and PUT Operations: Supports GET to read and send file contents to the client, and PUT to receive and write data from the client to a file.
• Error Handling: Provides appropriate error messages for various failure scenarios.

Technologies Used

• Language: C
• Libraries: Standard C libraries, Socket programming
• System Calls: fork(), socket(), bind(), listen(), accept(), recv(), send(), fopen(), fgetc(), fwrite()

Usage

1. Clone the repository.
2. Compile the tcp_server.c file using a C compiler.

Compiling the C file

gcc -o tcp_server tcp_server.c

Running the executable

3. Run the compiled executable providing the port number as a command-line argument.

./tcp_server <port_number>

Replace <port_number> with the desired port number (must be greater than 1024).
