Simple TCP Socket Server

Description

This project implements a simple TCP socket server in C. The server listens for client connections, receives messages from the client, and responds with a confirmation message. It demonstrates basic socket programming concepts such as creating a socket, binding, listening, accepting connections, reading, and writing data.

Features

• Listens for incoming client connections.
• Reads data sent by the client.
• Sends a confirmation message back to the client.
• Uses a Makefile for easy compilation.
• Error handling for failed operations.

Prerequisites

• GCC Compiler: Required to compile the C source files.
• POSIX-compliant system: Works on Linux/macOS.
• Basic knowledge of networking: Helps in understanding socket programming.

Installation

Clone the repository:

git clone https://github.com/mady20/cserver.git
cd cserver

Compile the project using:

make

This will generate two executable files:

• server: The server application.
• client: The client application.

To remove compiled binaries:

make clean

Usage

Starting the Server

Run the server with a specified port number:

./server <port_number>

Example:

./server 8080

Starting the Client

Once the server is running, start the client (assuming client.c is implemented):

./client <server_ip> <port_number>

Example:

./client 127.0.0.1 8080

How It Works

1. The server binds to a specified port and listens for incoming connections.
2. When a client connects, the server accepts the connection.
3. The server continuously reads data sent by the client.
4. The received data is printed on the server's console.
5. The server responds with a confirmation message.
6. The connection continues until terminated.

Notes

• Ensure the specified port is not blocked by a firewall.
• Modify client.c accordingly to communicate with the server.
• The server currently runs in an infinite loop; you may need to terminate it manually using Ctrl + C.
