Socket File Transfer

This project implements a file transfer mechanism using sockets in C. It allows you to send and receive files between a client and server over a network connection.

Prerequisites

To compile and run this project, you need:

• A C compiler (e.g., GCC)
• Linux or a Unix-like operating system

Usage

Preparation

1. Compile everything using the following command:

   make

Server

1. Run the server program:

   ./server <v4/v6> <port_number>

   Replace <v4/v6> with the v4 for IPv4 addresses or v6 for IPv6 adresses and <port_number> with the port number on which you want the server to listen for incoming connections.

Client

1. Run the client program:

   ./client <server_ip> <port_number>

   Replace <server_ip> with the IP address or hostname of the server, <port_number> with the port number on which the server is listening

How it Works

The server and client communicate using TCP/IP sockets. Here's a high-level overview of how the file transfer process works:

1. The server creates a socket and binds it to a specified port number. It listens for incoming connections from clients.

2. The client creates a socket and establishes a connection with the server using the server's IP address and port number.

3. Once the connection is established, the client can select and send files via cli using "select " and "send file".

4. The server receives the file chunks and writes them to a file on the server-side.

5. After the file transfer is complete, the client and server close their sockets and terminate the connection.

Limitations

• The maximum file size that can be transferred depends on the underlying operating system and file system limitations.
• The program assumes that the client and server are running on the same network and can communicate with each other directly.
