This is a very simple and dumb chat server where multiple clients can simultaneously connect and broadcast messages to each other. Under the hood, it makes use of TCP (transmission control protocol) via Berkeley Sockets.
The purpose is to apply concepts I learned in network programming.
First, Make sure you have CMake installed and available in your PATH.
Then,
mkdir build
cd build
cmake ..
makeThis will create an executable called server in the build directory.
To start the server from the command line, simply run ./server <PORT>.
You'll see something like this:
server: listening to connections on port 3000In order to connect to the server, you can use telnet or any similar program.
telnet localhost <PORT>Open it in multiple terminal windows to simulate multiple clients and have fun!
