Description

Peer to peer Timeline built with Kademlia.

Instructions

NOTE: Our project only works in the Linux environment due to the package simple_term_menu used for menus

1. Clone this repository:

git clone https://git.fe.up.pt/sdle/2021/t3/g13/proj2.git

2. From the root folder (proj2) run the following command to install the requirements:

• Create the Virtual Environment: python -m venv env
• Activate the Virtual Environment: source env/bin/activate
• Install the requirements: pip install -r requirements.txt

3. See the program usage using the following command:

python -m src -h

A detailed help message is printed, describing all the possible arguments. The default ip is 127.0.0.1, the default port for the network is 8000 and the default port for the direct connections is 7000.

For example, running a bootstrap node with the default values would be achieved by the following command:

python -m src -init

Running a new user using the port 8003 for the network and the port 7003 for the direct connections between the peers is achieved using the following command:

python -m src -p 8003 -pl 7003

If values aren't specified, the default ones that are in the config.ini file will be used.

Documents

A presentation and a video demonstration of this project can be found in the folder doc.
