Unable to get federation routing between two exchanges.

[Gary Taylor <sq...@SDF.ORG>]

I am trying to set up a federation between two brokers and
am unable to get a route working between the two.  I've
included a script below that I've been using and it may be easier
to understand than my verbal explanation.  
Exchange A on localhost port 5673 is the destination.
Exchange B on localhost port 5674 is the source. 
So I'm trying to route from B > A.  

As part of the script I send this message using spout:
spout -b localhost:5674 B.Q
Message(properties={'spout-id':
'1209db3e-225c-40f1-8017-3c62bd7120b2:0'})

It never arrives at Exchange A. 
Can anyone tell me what I've missed? 



# qpid-route route map localhost:5674

Finding Linked Brokers:
    localhost:5674... Ok

Dynamic Routes:
  none found

Static Routes:
  none found



# qpid-route route map localhost:5673

Finding Linked Brokers:
    localhost:5673... Ok
    localhost:5674... Ok

Dynamic Routes:
  none found

Static Routes:

  localhost:5673(ex=A.EX) <= localhost:5674(queue=B.Q)


In case the output below from qpid-stat gets wrapped badly,
the qpid-stat shows 
1 msg
1 msgIn
0 msgOut

# qpid-stat -b localhost:5674 -q

# Add routing queue

# Add route between A and B. ??? necessary ???

Resolved the issue and answering my own question for future reference.

Saw this in /var/log/messages 
[Broker] warning Client closed connection with 320: ACL denied anonymous@QPID creating a federation link (qpid/broker/ConnectionHandler.cpp:204)

Modified /etc/qpid/qpidd.acl by commenting the "deny" line as below:
#acl deny all create link
