Python TCP Socket Connection

Description

This project demonstrates a simple TCP server implementation in Python using the socket module. The server listens for incoming connections, sends a greeting message to the client, and then closes the connection.

Languages and Utilities Used

• Python3

Environments Used

• Kali Linux
• Visual Studio Code

Program walk-through:

• TCP Socket: Creates a TCP/IP socket using socket.AF_INET and socket.SOCK_STREAM.

• Server Binding: Binds the server to the host and port.

• Connection Handling: Listens for incoming connections and accepts them.

• Message Sending: Sends a greeting message to the connected client.

• Connection Management: Closes the client connection after sending the message.

How It Works (Client)

1. Establishes a TCP connection to a specified server and port.

2. Receives data from the server.

3. Closes the connection after receiving the message.

4. Prints the received message in ASCII format.

How It Works (Server)

1. Create a TCP Socket: Uses socket.AF_INET and socket.SOCK_STREAM to create a TCP/IP socket.
2. Bind to Host and Port: Binds the socket to the host (hostname) and a port (444).
3. Listen for Connections: Listens for up to 3 incoming connections.
4. Accept Connections: Accepts incoming client connections and prints the client's address.
5. Send Message: Sends a greeting message to the client.
6. Close Connection: Closes the client socket after sending the message.

Usage

To run the server:

1. Execute the script: python server.py

2. The server will start listening for incoming connections on port 444 and will send a greeting message to each connected client.

Requirements

• Python 3.x
• No additional dependencies
