Write code in PYTHON.TWO FILES SERVER.PY and CLIENT.PY

Keeping the specifications in mind below

Modify the client.py and server.py provided and

Use a 2 dimensional parity checker.

A. Simple server

#!/usr/bin/python

import socket # Import socket module

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) # Create a socket object

host = socket.gethostbyname(socket.gethostname()) # Get local machine name

port = 12345 # Reserve a port for your service.

s.bind((host, port)) # Bind to the port

print 'host ip', host

s.listen(5) # Now wait for client connection.

while True:

c, addr = s.accept() # Establish connection with client.

print 'Got connection from', addr

c.send('Thank you for connecting')

c.close() # Close the connection

B. Simple client

#!/usr/bin/python # This is client.py file

import socket # Import socket module

s = socket.socket() # Create a socket object

host = socket.gethostname() # Get local machine name/for this example

ports = 12345 #server port

portc = 32451 #client's own port for incoming connections (if any)

s.bind((host, portc))

s.connect((host, ports))

print s.recv(1024)

s.close # Close the socket when done

Lab 3: Error detection and recovery This lab focuses on detection of bit errors and recovering from such errors. Task: Generate a NxN matrix of bits, i.e., 0s and 1s only, at the client. The client transmits this matrix to the server. Before transmission, the client may induce a 1-bit error in the data at random. A 1-bit error means 1 is changed to 0 or 0 is changed to 1. Programming Tasks 1. Design and execute a program to detect all such 1-bit errors 2. Design an error correcting code so that the server can correct the 1 bit error
