Overview
In this assignment you will create a networked date/time server and a client to access the server.
The basic interaction between the client and server should be as follows:
Server establishes connection and listens for incoming client requests.
Client connects to server and sends ASCII request “What is the current date and time?”
Server responds with “Current Date and Time – 09/29/2016 09:00:01”
Client closes connection, server stays running listening for next connection
Detailed Requirements
Server
Only required to handle one client interaction at a time
Can listen on any IP & port you choose
Must respond to invalid requests with an error message
Valid request is “What is the current date and time?”
Response to valid request must be in the format:
“Current Date and Time – MM/DD/YYYY hh:mm:ss”
Client
Allows user to enter text commands to be sent to the server
Displays response back from server
Note - You can use the Python_Server.py and Python_Client_py files from Assignment #1 as your
starting point or you can start from scratch if you prefer.
Procedure
Part A – Develop your Applications
Using the information above, design and implement your applications using Python. (As discussed in
class you can use Python 3 or 2.7 but please make sure to indicate the version when you submit the
assignment!)
You will be graded on the following:
Design and function of your applications
Documentation within your applications (Yes, it is important. No one wants to work on
undocumented apps)
Part B – “Sniff” Request/Response between Server and Client apps
Using Wireshark (running on the machine hosting the Server app), capture the traffic between
your client and server applications and take a screen shot of the TCP packet showing the response
back from the server. The response will contain the Date/Time data.:
