TCPChat

TCP Chat Application

This is a simple TCP-based chat application built using Python. It allows multiple clients to connect to a server and communicate in real time.

Features

• Multiple clients can join the chat.
• Messages are broadcasted to all connected clients.
• Clients can join and leave the chat dynamically.
• Simple implementation using Python sockets and threading.

Prerequisites

• Python 3.10 or higher (Check your version by running python3 --version)

Installation

1. Clone the Repository

Usage

1. Run the Server

python3 server.py

You should see:

Server is running...

2. Run the Client

Open a new terminal and run:

python3 client.py

Enter a nickname when prompted.

3. Connect Multiple Clients

Open additional terminals and run more instances of client.py to simulate multiple users.

Troubleshooting

• If the server does not start, try a different port in server.py and client.py (e.g., PORT = 5050).
• If messages are not showing up, check if the server is running properly:

  lsof -i :55556

  If no process is listening, restart server.py.
• Firewall Issues on macOS: Allow Python through the firewall using:

  sudo /usr/libexec/ApplicationFirewall/socketfilterfw --unblockapp /usr/bin/python3

Next Steps

• Add a GUI using Tkinter.
• Implement message encryption for security.
• Deploy on a remote server for real-world use.
