In order to use this service you can download the LMO client from our GitHub repository LMO client.
You then generate a UUID 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 --dns --icmp --udp --tcp --ports 80,443,8080-8082
You can then search for the UUID on this site and identify if any successful connections have been made.
