TCP Server in C

A lightweight, efficient TCP server implementation in pure C. This project provides a simple echo server with a client example for testing.

Features

• ✨ Simple and clean C implementation
• 🚀 Lightweight and fast
• 🔌 Configurable port
• 📡 Echo server functionality
• 🧪 Includes test client
• 🛠️ Easy to build with Makefile

Building

make

This will compile both the server and client executables.

Usage

Server

Run the server with default port (8080):

./tcp_server

Or specify a custom port:

./tcp_server 9000

Client

Connect to server on localhost:

./tcp_client

Connect to a specific server and port:

./tcp_client 192.168.1.100 9000

Testing with netcat

You can also test the server using netcat:

nc localhost 8080

Architecture

• tcp_server.c: Main server implementation with connection handling
• tcp_client.c: Simple client for testing server functionality
• Makefile: Build configuration

Configuration

Default settings in tcp_server.c:

• PORT: 8080
• BUFFER_SIZE: 1024 bytes
• MAX_CLIENTS: 10 concurrent connections

Future Enhancements

• Multi-threaded connection handling
• SSL/TLS support
• Custom protocol implementation
• Connection pooling
• Logging system
