 Replying to [ticket:5376 kevin]:

 `TestingTorNetwork`.

 Right. You haven't shown a descriptor here -- what does the exit policy
 section in the descriptor look like?

 Rejecting.`

 My first thought is that the client doesn't know about any relays.

 Speaking of which! Tor 0.2.3 uses microdescriptors, rather than
 descriptors. So the relay will be publishing a descriptor to the directory
 authorities, and the directory authorities will be producing a microdesc-
 consensus and microdescs. Clients should have these files:
 {{{
 -rw-------  1 arma arma  565725 Mar 13 08:44 cached-microdesc-consensus
 -rw-------  1 arma arma 2656826 Mar 11 13:42 cached-microdescs
 -rw-------  1 arma arma  448091 Mar 13 08:44 cached-microdescs.new
 }}}

 and microdescs don't specify addresses, just ports.

 I wonder if we have broken ExitPolicyRejectPrivate in 0.2.3.x, not just
 for TestingTorNetwork.

 Suggested workaround for now: set "UseMicrodescriptors 0" in your torrcs.
