UDP Task

In the program explained during the lab, in the client side

The OS assigns the port number automatically.

The client sends a line of characters (data) from its keyboard to server.

Update the client side of program so that it takes 2 arguments

The port it will bind to.

The message that will be sent to the server.

Keep the server side of program as it is

Use the screenshots in the presentation as a reference

check the testArg.py --> an example to show you how to use arguments

TCP Task

In the program explained during the lab

the client sends only 1 message to server ‘hello from tcp client’

server responds with the uppercase message.

Update the program / make a simple chat program so that

Client can send/receive multiple messages to server.

A special exit message is used to disconnect ‘Exit’.

Each time client sends a message, server responds with a confirmation of receiving it and its length

(use the screenshots in the presentation as a reference)

using python .

tcp client code

from socket import *
serverIP = '127.0.0.1'
serverPort = 12000
clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverIP,serverPort))
sentence = input('Input lowercase sentence:')
clientSocket.send(sentence.encode())
modifiedSentence = clientSocket.recv(1024)
print ('From Server:', modifiedSentence.decode())
clientSocket.close()

tcp server code

from socket import *
serverPort = 12000
serverSocket = socket(AF_INET,SOCK_STREAM)
serverSocket.bind(('',serverPort))
serverSocket.listen(1)
print ('The server is ready to receive')
while True:
connectionSocket, addr = serverSocket.accept()

sentence = connectionSocket.recv(1024).decode()
capitalizedSentence = sentence.upper()
connectionSocket.send(capitalizedSentence.encode())
connectionSocket.close()

udp client code

from socket import *

serverIP = '127.0.0.1'
serverPort = 12000

clientSocket = socket(AF_INET, SOCK_DGRAM)
clientSocket.bind(('',0))

message = input('Input lowercase sentence:')
clientSocket.sendto(message.encode(), (serverIP, serverPort))
modifiedMessage, serverAddress = clientSocket.recvfrom(2048)
print (modifiedMessage.decode())

clientSocket.close()

udp server code

from socket import *

serverPort = 12000
serverSocket = socket(AF_INET, SOCK_DGRAM)

serverSocket.bind(('', serverPort))

print ("The server is ready to receive")

while True:
message, clientAddress = serverSocket.recvfrom(2048)
modifiedMessage = message.decode().upper()
serverSocket.sendto(modifiedMessage.encode(), clientAddress)
