meskio,

Presently, it sounds like security through obscurity (hide the Tor listener on a publicly-facing port, not within nmap's default top-1000 most scanned ports, and among a number of publicly-facing, non-Tor ports with a touch of Snort or Suricata IPS is the best solution for now)?

Hopefully, it won't take another 10 years to implement this security request and improve Tor Bridge survival rates.

I appreciate the status update of Bug #7349.

BTW... My bridge has been running for about a week. I am able to successfully connect to it manually. When should I expect to see stats for my bridge? Currently, I continue to receive the message "no resources for the given id."

Thank you for your assistance.

Respectfully,


Gary
