 Sep 19 22:42:11.251 [warn] Problem bootstrapping. Stuck at 85%: Finishing
 handshake with first hop. (No route to host; NOROUTE; count 1;
 recommendation warn)

 $ telnet 89.54.142.227 443
 Trying 89.54.142.227...
 telnet: Unable to connect to remote host: No route to host

 This isn't a problem with my network, it's a problem with that host.

 And it looks like Tor can't tell the difference:
 $ grep END_OR_CONN_REASON_NO_ROUTE *.h
 or.h:#define END_OR_CONN_REASON_NO_ROUTE       6 /* no route to host/net
 */

 We should teach it the difference.

 Step one is to do this in errno_to_orconn_end_reason(), which I think will
 solve the particular issue here.

 Step two would be to solve it in tls_error_to_orconn_end_reason(), but I
 bet that might be trickier.

Comment:

 shadowsjack's stuff isn't related to this problem; it's an ssl handshake
 thing.  Does it still occur for you in a recent version?  We did some more
 fixes since January.  If not, please open a new ticket.

 arma: marking this for 0.2.3.x.
