Subject [jira] [Created] (AMQ-4023) updateClusterClients with multiple NICs: wrong hostnames

-----------------------------------

             Summary: updateClusterClients with multiple NICs: wrong hostnames
                 Key: AMQ-4023
                 URL: https://issues.apache.org/jira/browse/AMQ-4023
             Project: ActiveMQ
          Issue Type: New Feature
          Components: Broker
    Affects Versions: 5.6.0
            Reporter: Raul Kripalani


TcpTransportServer's instance variable 'connectURI' is initialised when the socket is bound.
If the address is ANY ADDRESS (0.0.0.0) in a multi-NIC machine, the socket is bound to all
NICs, but only a *single* connect URI is registered.

{{InetAddressUtil.getLocalHostName()}} is invoked to calculate the connect URI.

The connectURI is used to represent the current broker when the list of peers is populated
as part of the updateClusterClients feature.

In real life, a client transport connection could come in from any NIC, where each NIC has
a different hostname. So it's easy to send back a wrong hostname in the updated list to the
client.

I propose a solution comprised of the following:
* Remember the *actual* connect URI for each individual transport connection and use that
for the current broker in the updated connect list.
* Turn the connectURI variable on TcpTransportServer into a List<String>.
