Make our test network public
It would be really great if we could have our test network public so people can join it to help and other projects could use its data openly.
However, by doing so right now, the network can basically become a "Tor 2" or have the issue that any tor from the current network could use the nodes in the test network without it being in the consensus. This is problematic since operators signing up for the test network should not be receiving legitimate traffic or their Exit being used for regular traffic which is bad.
Here are some ideas we can play around with:
Make relay in the test network advertise that they are for "Testing" in their descriptor and then making the dirauth ignore that line for the real network consensus which would make a normal tor ignore them. However, it doesn't protect against a modified tor that just ignore that line in the descriptor and end up picking the nodes.
Provide a firewall script for the Exit node operator that blocks all outbound connections except maybe one localhost service that could be setup for testing the actual Exit circuit. This is also partial because hidden service.
Make the test network not connect to unknown relays but I'm not to sympathetic to this fix as it makes the test network behave differently from the real one.
Do NOT make the test network public and just scrubs the data for IP/Port so we can put that data openly but the network stays private.
