sohoxic / connectify

In this project, we implement a File Transfer Protocol (FTP) system for efficient file exchange over a network.

Connectify

Decription

• Connectify is a FTP (File Transfer Protocol) server that facilitates seamless file transfer between multiple clients and the server over a network.
• The server hosts files and allows multiple clients to connect, upload, and download files over TCP sockets. This code doesn't use the standard FTP protocol. This code can only run on Linux (debian-based distros).

Features

• Upload and Download: Allows users to upload files from the client to the server and download files from the server to the client.
• Peek: Allows client to view 1st 1kB of his file on server
• View & Remove: Allows clients to see the names of his files on server and remove them.
• Security: Implements authentication to ensure the confidentiality of transferred files.
• Consistency: Server Maintains a Log file for every transaction

FTP Server and Client Setup Guide

Building the Executables

1. Organize the server.c, common.c, and the Makefile in a folder [X] on PC1.
2. Organize client.c, common.c, and the Makefile in a folder [Y] on PC2.
3. Navigate to the respective folder (X/Y) and execute make to build server.out and client.out files.

Setting Up the Server.

make

1. a.out is created in the server folder.
2. Create a file named "id_passwd.txt" in folder [X], containing usernames and passwords of multiple clients.
3. Each entry in id_passwd.txt should follow the format:

[userName]/:[password]

4. In the same folder [X], create an empty directory with the same name as each client's username for every user.
5. Launch the server by running ./server.out [ServerPortNo].

./server.out [ServerPortNo]

Setting Up the Client

1. Only the client.out file is required in the client computer's folder [Y].
2. To run the client, navigate to folder [Y] and execute ./client.out [ServerIP] [ServerPort].

./client.out [ServerIP] [ServerPort]

Note: Replace terms inside [...] as per your system configuration.
