cpp-linux-sockets-app

Client-server application based on Linux sockets and written in C++ programming language.

Overview

Server

The server is capable of connecting multiple clients and processing their requests.

main_server.cc is specialized in such way that it can only process 3 types of commands:

1. connections - return current number of connections to the server
2. count <message> - count letters in the message and return it in the table form
3. send <message> - send a message to all other connected clients

If you want to wtite down your own server - you can specialize server.h server by providing ResponseProcessor caller to the Serve method.

Client

The client is capable of connecting to the server once and sending/receiving data with it.

main_client.cc is specialized to endlessly ask for command and send it to the server if it is correct. After each succesfull transaction to the server client checks for incoming messages from server or other clients.

Installation

cmake -B build src
cmake --build build

Launching

Server

Server accepts only one command-line argument - port on which it will be serving.

./server 8888

Client

Client accepts two command-line arguments: address and port. Instead of actual address localhost can be specified to connect to local instances of the server.

./client localhost 8888
