Python TCP Echo Server

A simple, safe, and robust TCP Echo Server written in native Python. This project is a great foundational example for learning network programming and socket handling.

Features

• Listens on localhost:8080 (TCP)
• Gracefully handles client connections and disconnections
• Immediately releases the bound port on exit using SO_REUSEADDR
• Safely echoes received data back to the client without executing system commands

Usage

1. Start the Server

Run the script in your terminal to start the server. It will begin listening on port 8080.

python simple.py

2. Connect with a Client

Open a new terminal window and connect to the server using netcat (or telnet).

nc 127.0.0.1 8080

Once connected, anything you type into the netcat terminal will be sent to the server and safely echoed right back to you.

3. Stop the Server

To stop the server, press Ctrl+C in the terminal where it is running.
