Distributed File System

Project Overview

This project implements a Distributed File System using C and socket programming. The system consists of three servers: Smain, Spdf, and Stext. It supports multiple client connections, allowing clients to upload, download, and manage files transparently. The Smain server handles communication and distributes specific file types to Spdf and Stext in the background.

Features

Upload: .c files (stored in Smain), .txt files (stored in Stext), and .pdf files (stored in Spdf).
Download: Retrieve any file via Smain, with Smain fetching files from Stext/Spdf in the background.
Delete: Remove files from the respective servers.
File Listing: View available files in specified directories.
Archive Creation: Generate tar files for .c, .txt, or .pdf files.

Project Components

Smain.c: The main server that handles client interactions.
Spdf.c: A server that manages .pdf files.
Stext.c: A server that manages .txt files.
client24s.c: Client-side program for interacting with the servers.

Prerequisites

Basic knowledge of socket programming in C.
Linux environment.

Installation

Clone the Repository:

git clone https://github.com/hetvishah1005/MultiServerFS.git
cd MultiServerFS

Running the Project

Compile the .c files on different machines or terminals.

gcc Smain.c -o Smain
gcc Spdf.c -o Spdf
gcc Stext.c -o Stext
gcc client24s.c -o client24s

Run the servers and the client on different terminals:
```
./Smain
./Spdf
./Stext
./client24s
```
The client can now send commands to Smain and interact with the system.

Usage

Commands

`ufile filename destination_path`

Upload a file to the server.

Description: Uploads the file specified by filename to the destination_path on the server.
Example:
```
client24s$ ufile sample.c ~smain/folder
```

`dfile filename`

Download a file from the server.

Description: Downloads the file specified by filename from the server to your local machine.

Example:

client24s$ dfile ~smain/folder/sample.txt

`rmfile filename`

Delete a file from the server.

Description: Deletes the file specified by filename from the server.

Example:

client24s$ rmfile ~smain/folder/sample.pdf

`dtar filetype`

Create a tar archive of files of a specific type.

Description: Creates a tar archive of all files matching the specified filetype (e.g., .c, .txt, .pdf) on the server.
Example:
```
client24s$ dtar .c
```

`display pathname`

List files in a specified directory.

Description: Lists all files and directories under the specified pathname on the server.
Example:
```
client24s$ display ~smain/folder
```

This will list .c, .pdf, and .txt files in the specified directory.

Error Handling

The system provides appropriate error messages for invalid commands, incorrect paths, network issues, or failed file operations.
Error messages guide users to correct their actions.
