Simple TCP Server-Client

Description

Simple TCP Server-Client is a basic C++ application implementing a client-server model using the Asio library for asynchronous input-output operations.

The server can accept connections from clients, handle incoming messages, and log them. The client supports periodic message sending to the server at a defined interval.

This project is being developed for self-educational purposes, but it can be used for any of your tasks. In particular, you can build something more complex using the example provided in the existing main.cpp.

Features

Server:

• Asynchronous acceptance of client connections.
• Logging of incoming messages.
• Multithreaded handling of each connection.

Client:

• Connect to the server by IP and port.
• Periodic message sending with a specified interval.
• Automatic retrying of message sending after successful connection.

Requirements

• Unix-type system
• CMake 3.18+
• C++11 compatible compiler
• vcpkg (for asio)
• Asio library

Cmake install

Debian / Ubuntu

sudo apt update sudo apt install cmake

Fedora

sudo dnf install cmake

CentOS/RHEL

sudo yum install cmake

Arch

sudo pacman -S cmake

vcpkg install

Building the Project

1. Clone the repository:

   git clone https://github.com/CrispusCrew/IP_simpleTCP.git
   cd IP_simpleTCP

2. Build the project with CMake & install the binaries:

   chmod a+x build.sh    # if nessesary
   ./build.sh

Usage

Server

• Start the server, specifying the port to listen on by args:

  ./bin/server <port>

• Or use cmd input after start

  ./bin/server
  Enter portTCP
  <port>

• Stop server by typing "exit" or simple "e"

  exit

Client

• Start the client, specifying the client name, port and ping period on by args:

  ./bin/client <portTCP> <clientMsg> <pingPeriod>

• Or use cmd input after start

  ./bin/client
  Enter clientMsg, portTCP and pingPeriod
  <portTCP> <clientMsg> <pingPeriod>

• You also can use float value of pingPeriod (for example every 0.5 seconds)

  ./bin/client name1 12345 0.5

• Stop client by typing "exit" or simple "e"

  exit
