Task

Functional requirements:

• the application enables communication between two instances over a network
• the user enters their name upon launch
• messages are exchanged in real time * each message contains the sender’s name
• the application runs until the user exits

Technical requirements:

• language: C++ or Python
• system: Linux
• communication method and application architecture to be decided by the candidate
• project placed in a GIT repository
• the project should include a Readme or documentation in another format containing, amongst other things: build/run instructions and any limitations
• the solution should be buildable/runable by a third party on two Linux machines.

Launching the application

all commands need to be executed in Linux terminal

If the git package is not installed, you must install it

On a Debian-based system

  sudo apt-get install git-all

On a Fedora system

dnf install git-all

Cloning the application locally

  git clone https://github.com/AlexFromPoland/Simple-P2PChat.git

Locate the project in the saved directory

  cd Simple-P2PChat

Running the application

  python3 P2Pchat.py

after launching the application:

• you must enter the display name on the network
• new peers on the network are automatically added to the chat

Tested

The application has been tested on both a Linux (Debian) virtual machine and on the Windows operating system, but only with a maximum of two connections

Application Limitations

• The application works only on a local network where users are connected to the same network

• No NAT traversal

• The broadcast port (by default UDP port 5000) must be accessible

• The chat port (by default TCP port 4000) must be accessible
