[tor-relays] Need advice on IPv6 bridge config

[Steve Snyder]

I'm getting my feet wet with IPv6 bridges, so far without success.  I 
set up a test bridge (0.2.3.22-rc) on one network and plugged the 
address:port into Vidalia (TBB x86_64-2.2.39-1) on another.

The bridge config looks like this in part (local IPv4 address hidden):

Address aa.bb.cc.dd
OutboundBindAddress aa.bb.cc.dd
ORPort [2a00:1d70:ed15:37:235:53:64:0]:443

At run time the final Tor log entries are:

[notice] Tor has successfully opened a circuit. Looks like client 
functionality is working.
[notice] Bootstrapped 100%: Done.

In Vidalia the message log entries are:

[Notice] Learned fingerprint 24432B99CA2533BC95ABF66C7AFE835F96DD2B2D 
for bridge 2a00:1d70:ed15:37:235:53:64:0:443
[Notice] no known bridge descriptors running yet; stalling

That last line is repeated periodically forever.

So I have enough connectivity to correctly determine the fingerprint, 
bit not enough to get bridge descriptors.

What am I doing wrong?

Thanks.
