Re: [tor-relays] Bad experience with hetzner.de and "Trusted Tor Traceroutes" experiment

[Paul Görgen <tor@xxxxxxxxxxx>]

Hi again,

Hetzner now blocked my testing Server. This gave me chance to finally 
get into contact with a human person. They said their IDS triggered on 
"connects to unrouted IPs" (I assume that will be connects to unrouted 
IPs per time). I will try to convince them to set up an exception rule 
for my server but I am not too hopeful.

As a backup: I guess that there is no way to make sure that you don't 
try to connect to unrouted IPs, given that the IPs owner can decide to 
route or not route at will, right?

If both don't work I will not be able to run the script.

Best,

Paul Görgen
