The stem approach (#3) ought to work in general -- the information here isn't enough to tell what the problem is, exactly. Is it possible that the circuit you are constructing is failing for some reason? -- Nick _______________________________________________ tor-dev mailing list tor-dev@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-dev
