TCP-Client-Server

A basic TCP Client and Server implementation in Python.

Key Features & Benefits

• Simple TCP Communication: Establishes a fundamental client-server connection for data exchange.
• Easy to Understand: Clear and concise code, ideal for beginners learning network programming.
• Customizable Port: Allows users to configure the port for communication.

Prerequisites & Dependencies

• Python 3.x: Ensure Python 3 or a later version is installed on your system.
• No external libraries required: This project only uses the built-in socket module.

Installation & Setup Instructions

1. Clone the repository:

   git clone https://github.com/Paddywelch117/TCP-Client-Server.git
   cd TCP-Client-Server

2. No installation needed: The project consists of Python scripts that can be run directly.

Usage Examples

1. Run the server:

   python TCP\ Server.py

2. Run the client:

   python TCP\ Client.Py

   Note: Ensure the server is running before starting the client. The client will attempt to connect to the server at the specified host and port.

Code Snippets

TCP Server.py:

import socket


#Creating the socket object
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = socket.gethostname()
port = 4444

serversocket.bind((host, port))

#Starting TCP listener
serversocket.listen(3)

while True:
    #Starting the connection
    clientsocket,address = serversocket.accept()

    print("received connection from: %s " % str(address))

    #Message sent to client after successful connection
    message = 'hello! Thank you for connecting to the server' + "\r\n"
    clientsocket.send(message.encode('ascii'))

    clientsocket.close()

TCP Client.py:

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

host = socket.gethostname()
port = 4444

s.connect((host, port))

tm = s.recv(1024)

s.close()

print("The time got from the server is %s" % tm.decode('ascii'))

Configuration Options

• Port: The default port is 4444. You can modify the port variable in both TCP Server.py and TCP Client.Py to use a different port. Ensure that both the client and server use the same port.

  # Example: Changing the port to 12345
  port = 12345

• Host: The server uses socket.gethostname() to determine the host. This is typically your local machine's hostname. You can change this to a specific IP address if needed, but ensure the client can reach that address.
