Simple TCP/IP Server and Client

This project implements a basic TCP/IP server and client that use sockets to communicate over a network. The primary function of this system is to manipulate a simple key-value store, demonstrating fundamental network interaction capabilities.

Features

• TCP Server: Handles multiple client connections using non-blocking sockets.
• Key-Value Store: Supports basic operations like SET, GET, and DELETE.
• Custom Binary Protocol: Uses a simple protocol for message passing between client and server.

Requirements

• GCC compiler
• Linux or Unix-like OS

Building the Code

Clone the repository and compile the server and client:

git clone https://github.com/yourusername/simple-tcpip-server-client.git
cd simple-tcpip-server-client
g++ server.cpp -o server
g++ client.cpp -o client

Running the Server

To start the server, navigate to the directory where the server executable is located and run:

./server

The server will listen on port 1234 for incoming connections. Ensure the port is available and not blocked by any firewall settings.

Running the Client

To interact with the server using the client, open a new terminal window and run the following commands depending on the action you want to perform:

• Set Value:

./client set your_key your_value

Replace your_key and your_value with the key and value you wish to set.

• Get a value:

./client get your_key

Replace your_key with the key whose value you want to retrieve.

• Delete a key:

./client del your_key

Replace your_key with the key you wish to delete.

These commands allow you to interact directly with the key-value store implemented by the server.

Usage Examples

• Setting Value:

./client set username alice

• Retrieving a value:

./client get username

• Deleting a value:

./client del username
