Re: Using Tor with BitTorrent

I believe that the only mechanism for inward connecting to a listener with
Tor is not via an out-proxy but via a "hidden service" - i.e. there is no
way to establish a proxy listener at an out-proxy (but I'm sure someone will
correct me if I'm wrong here:)

Use of a "hidden service" requires the inward connecting clients to
explicitly connect through Tor, as outlined in the Azureus document, so
there's no way to get such inward connections from non-Tor aware clients.


PS I also get a load of the error logs similar to the ones you report on
Windows with the latest RC and logging switched off (well, not enabled).

Hi Paul,

thanks for your quick answer, I couldn't answer so quick, had not much time
recently. I read some stuff about BitTorrent protocol and the Azureus
documentation now, and I guess a few things became clear now.
So you say, as I am only outward connected, nobody can connect to me, but I
can upload to clients I am connected with. So in my understanding I should
be completely anonym with these bi-directional down-/uploads, as long as I
restrict the program to only connect via Tor, right?

I re-installed Azureus now, and with help of the documentation I finally
made it work now. No outgoing connection anymore, all the traffic goes
through Tor and even the "...application is giving Tor only IP adress..."
failure is gone.
But I thought about the problem, that nobody can connect to me. What if I
would make a connection to a Tor outproxy and this outproxy would offer me a
listinig port to which clients can connect to me. Then all data could be
send over the already existing connection. Wouldn't that be a possible
solution. Or maybe there is some sort of an external service to which I
could connect via Tor and which then provides me that port. What do you

Besides: The "[warn] conn_read(): Unhandled error on read for OR
connection (fd368); removing" problem is gone since I de-installed some
programs, but I still have that problem saying: "[warn] circuit_log_path():
circ (length 3, exit randomtrash):solid(open) cannabis(open)
randomtrash(open)" if anybody could help
