Environment

• Ubuntu 24.04 LTS
• gcc 13.2.0
• GNU Make 4.3

How to Build

There are several ways to build the programs:

• Build all the programs:

  make

  This will generate two programs: client and server, under the current directory.

• Or accelerate the building phase with multiple cores:

  make -j$(nproc)

  Warning: build with this method may mess up the output messages from builing.

• Only build the client program:

  make client

  This will only generate client.

• Only build the server program:

  make server

  This will only generate server.

Clear the outputs generated from the building phase:

make clean

This will delete both client and server.

How to Run

1. Run the server side:

   ./server <port>

   • port: Specify the port to which the server should bind. The range is between [1024, 65535].

2. Run the client side:

   ./client <host> <port>

   • host: The host that server is running on. If the server is run locally, type 127.0.0.1.
   • port: The port to which the server binds.

   Note that it is possible to run multiple clients simultaneously.
