and a log message "Launching a one-hop circuit for dir tunnel."
No, one-hop circuits are for begin_dir cells. See 6.2.1 in
tor-spec.txt. They let you connect to a directory port in an encrypted
authenticated manner, which can also be handy when your local network
is filtering certain http requests or ports. The one-hop circuits
are intended for cases where currently you'd just be making a direct
connection: now you connect to the Tor server and ask to connect to
Thanks for the clarification! That makes sense to me now.
