All:

After enabling Tor debug logging, we were able to verify the procedure of the router_do_orport_reachability_checks() function.

The router_do_orport_reachability_checks() function creates a circuit using a random Guard and Middle Relay with the Exit Relay always being itself.

This can be verified within the debug logs and viewing the connections section of the nyx application.

Apologies, if this is common knowledge. We needed to confirm the procedure to resolve issues related to Tor's Self-Test.

Respectfully,

Gary

Does anyone here know the procedure of the router_do_orport_reachability_checks() function?

I've increased logging of my Tor Relay to info and taken several packet-captures, but can't seem to identify connections initiated by my Tor Relay when verifying my ORPort reachability. I just see connections from other Tor Relays initiate connections with my Tor Relay.

Any detail that can be provided regarding the procedure of the router_do_orport_reachability_checks() function is greatly appreciated.

Respectfully,

Gary
