Start the first node

  cd Node
  python3 main.py --firstNode -port [port number]

Change [port number] for any port you want.

Start the rest of the nodes

  cd Node
  python3 main.py -address [IP]:[port] -port [port number]

Change [IP] for the IP of the node you want to connect, if you only have one node (first node) use the IP of that node, the same for [port], example (192.168.0.2:1234). Change [port number] for any port you want.

Run the client, open other terminal

Upload

python3 client.py --upload -address [IP]:[port] -fileName [file name]

Change [IP] for the IP of the node you want to connect, if you only have one node (first node) use the IP of that node, the same for [port], example (192.168.0.2:1234). Change [file name] for the name of the file do you want to upload, it have to be in the same folder of main.py.

Download

python3 client.py --download -address [IP]:[port] -magnetLink [magnet link]

Change [IP] for the IP of the node you want to connect, if you only have one node (first node) use the IP of that node, the same for [port], example (192.168.0.2:1234). Change [magnet link] for the magnet link of your file, is looks like 7399ccd544529d1bf2dd74f7e0814bcbdee42fb536c872a0850aaffdc182775f.
