Overview

      Please read the instructions section below before proceeding.

Instructions

    1.   Download this repository and locate the folder on your computer

    2.   Before proceeding, ensure you have all the following files:

           serv.py cli.py client-data.txt and the uploads subfolder containing server-data.txt

    3.   Open two terminals in your OS. One of these servers will be the server, and the other will be the client.

    4.   In one of your terminals run the serv.py script using the following command:

           python3 serv.py <PORT_NUMBER>

           The server name will be printed to the terminal. Copy this, you will need it for the next step

    5.   In the other terminal, run your cli.py script using the following command:

           python3 cli.py <server_name> <PORT_NUMBER>

    6.   Once both scripts are running, your client terminal will prompt you to enter one of four ftp commands:

           ls - the server will send a string of file names to the client

           get <file_name> - the server will send a file name to the client

           put <file_name> - the server will recieve the specified filename from the client

           close - the server will close the FTP connection after receiving this command from the client

File Structure

Demo

    LS Command

       As expected, the server only returns server-data.txt, the default server data

    PUT Command

       Here we upload client-data.txt to the server

       i.e. client-data.txt can now be found in uploads

    LS Command

       Now the server returns server-data.txt and also client-data.txt since we just sent it to the server in the step above

    GET Command

       Here we request and download server-data.txt from the server to the clients computer
