You could give the command-line tool "carml" a try. See here: https://carml.readthedocs.io/en/latest/ You'll want to use something like "carml circ *,*,*" to build a 3-hop circuit through Tor-chosen relays (or replace any of the *'s with a fingerprint) and then "carml stream --attach <circ-number>" to attach streams. -- meejah
