nodes-health

Small application to filter gmc nodes

What exactly it does

• nodes-health, saves new nodes in files/bootnodes-not-filtered.json
• Filters files/bootnodes-not-filtered.json for nodes ip/port in the /files/bootnodes-ip-and-port.json
• Runs scan for opened and close ports and saves as files/bootnodes-opened.json' and files/bootnodes-closed.json' files
• Looks for nodes with opened port in the files/bootnodes-opened.json' file and finds those nodes in the files/bootnodes-not-filtered.json` file
• Saves the final result in the www/music-bootnodes/bootnodes.json.
