First download the client lmo-client.py. You then generate a UUID on this page and register it on this site. After that, you can feed the UUID into the client and run a command like this: python3 lmo-client.py --uuid 5eb2df1c-8257-4abb-a6bf-c4dbaeada1db -A --ports 80,443
You can then search for the UUID on this site and identify if any successful connections have been made.
