Simple UDP Server

This is a basic Python UDP server that listens for incoming datagrams and prints messages received from clients. It runs a listener in a separate thread and allows the server operator to send messages via the console. The current implementation sends messages back to the server address (for demo/testing purposes), but can be extended to respond to actual client addresses.

Features

• Uses UDP sockets (socket.SOCK_DGRAM)
• Listens for incoming messages in a separate thread
• Prints received messages from clients
• Allows sending messages from server console

How to Run

1. Clone or download the repo.
2. Run the server script:

python server.py

3. Connect with a UDP client like nc (netcat):

nc -u localhost 10000

4. Type messages in the client to send them to the server.
5. Type messages in the server console to send messages (currently sent to localhost:10000, can be modified to respond to clients).

Notes

• The server uses UDP, which is connectionless — there are no persistent client connections.
• Messages from clients are printed in the console along with their address.
• Currently, messages sent from the server go to its own address (localhost:10000); you can update the code to store and respond to client addresses dynamically.
• You can enhance the server by keeping a list of client addresses and sending replies back to them individually or broadcasting.
