Python Networking Protocols

Introduction

In this lab, we will dive into the world of Python networking protocols in a captivating scenario set on the mythical island of Bennist. The island is inhabited by mystical creatures and guarded by the formidable Dragon Sentinels. The goal of this lab is to navigate through the network of caves on Bennist Island and communicate with the Dragon Sentinels using Python networking protocols.

Setting Up the Network Interface

In this step, we will start by configuring our network interface for communication with the Dragon Sentinels.

Open a Python script named /home/labex/project/network_setup.py using your preferred text editor and add the following code to configure the network interface:

import socket

## Create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

## Set up the network interface details
host = '127.0.0.1'
port = 22
s.connect((host, port))

## Connection successful, print a message
print("Connected to", host, "on port", port)

Run the script:

python network_setup.py

The information below should be displayed on your terminal:

Connected to 127.0.0.1 on port 22

Sending Messages to Dragon Sentinels

In this step, we will continue communicating with the Dragon Sentinels by sending them messages using Python networking protocols.

Open a Python script named /home/labex/project/send_message.py using your preferred text editor and add the following code to send a message to the Dragon Sentinels:

## send_message.py
import socket

## Create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

## Set up the network interface details
host = 'dragon.sentinel.com'
port = 12345
s.connect((host, port))

## Send a message
message = "Hello, Dragon Sentinels!"
s.sendall(message.encode('utf-8'))

## Receive and print the response
response = s.recv(1024).decode('utf-8')
print("Response from server:", response)

Run the script:

python send_message.py

The information below should be displayed on your terminal:

Response from server: SSH-2.0-OpenSSH_8.9p1 Ubuntu-3ubuntu0.6

Summary

In this lab, we have delved into the fascinating world of Python networking protocols by simulating communication with the Dragon Sentinels on Bennist Island. We have configured the network interface and sent messages using Python scripts, enhancing our understanding of networking protocols and their application in Python.
