Simple File Transfer System

Overview

This system consists of a server and client component designed to facilitate basic file transfer operations, including uploading and downloading files between a client and server over a network.

Features

• Server: Handles incoming connections, processes commands for file retrieval (download) and storage (upload), and manages data transmission.
• Client: Initiates requests for file operations, receives server responses, and handles file download or upload procedures.

Requirements

• Python 3.x
• Basic understanding of network programming and socket API

Installation

1. Clone or download the repository containing the server and client code.
2. Ensure Python 3.x is installed on both the server and client machines.

Usage

Server

To start the server, run the following command in a terminal:

python server.py

The server will listen for incoming connections and respond to client requests.

Client

To interact with the server, run the client script from another terminal:

python client.py

Upon starting, the client will connect to the server and present an interface for sending commands.

Supported Commands

1. USER: Sets the username for authentication, preparing the system for user login.
2. PASS: Provides the password for the specified user, used in conjunction with USER for authentication.
3. LIST or LS: Lists the contents of the current or specified directory, showing files and directories.
4. RETR: Downloads a file from the server to the client.
5. STOR: Uploads a file from the client to the server.
6. MKD or MKDIR: Creates a new directory in the current working directory.
7. RMD or RMDIR: Removes a directory if it is empty.
8. PWD: Displays the current working directory of the server.
9. CDUP: Moves the current working directory to the parent directory.
10. CWD or CD: Changes the current working directory to a specified path.
11. DELE or RM: Deletes a file from the server.
12. QUIT: Closes the connection and ends the session.
13. REPORT: Generates a report of server activity, useful for administrative purposes.
14. HELP: Provides information on available commands and their usage.

Configuration

• The server and client IP addresses and port numbers can be configured in the respective scripts.
• Ensure the server script is running before attempting to connect with the client.
