I've done this, and also added the EXTENDED keyword to get more
information, at Mike Perry's advice. It's helped narrow the scope of
the problem down to a few distinct classes of errors. Recreating the
above situation, I get a more useful message from the socket:
C 20070815020009: EXTENDCIRCUIT 0 [fingerprintscrubbed],[fingerprintscrubbed]
S 20070815020009: 250 EXTENDED 22
S 20070815020009: 650 CIRC 22 LAUNCHED
S 20070815020009: 650 CIRC 22 FAILED REASON=OR_CONN_CLOSED
> B) What do your Tor logs say?
In the above example at INFO level, all I get is this:
Aug 15 02:00:09.185 [info] handle_control_authenticate():
Authenticated control connection (9)
Aug 15 02:00:09.317 [info] circuit_n_conn_done(): or_conn failed. Closing circ.

I'm getting a list of nodes using
GETINFO desc/all-recent
And choosing random paths with acceptable exit policies from the
output. I was working from the assumption that this provides a list
of routers that are all currently usable...maybe my problem is in this
thinking?
