Alan Conway commented on DISPATCH-878:
--------------------------------------

FYI, on Unix platforms you can find the port using standard UNIX tools like 
lsof, ss or netstat - with no help from qdrouterd. These tricks work on any 
server with a single listening port - it gets trickier if your router has 
multiple listening ports:

{code}
[aconway@grommit ~]$ lsof -p $(pidof qdrouterd) | grep TCP
qdrouterd 19463 aconway    7u     IPv4 7805194       0t0     TCP 
localhost:42433 (LISTEN)
[aconway@grommit ~]$ ss -tlp | grep qdrouter
LISTEN     0      50     127.0.0.1:42433                    *:*                 
    users:(("qdrouterd",pid=19463,fd=7))
[aconway@grommit ~]$ netstat -tlp | grep qdrouter
tcp        0      0 localhost:42433         0.0.0.0:*               LISTEN      
19463/qdrouterd     
{code}

> qdrouterd should log real port if port 0 was specified for the listener port 
> property in qdrouterd.conf

>                 Key: DISPATCH-878
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-878
>             Project: Qpid Dispatch
>          Issue Type: Improvement
>          Components: Container
>         Environment: OS: Red Hat Linux Server release 6.4
> Dispatch version: 0.7.0
>            Reporter: Jeremy
>
> For such a qdrouterd.conf configuration:
> {noformat}
> router {
>     mode: standalone
>     id: Router.A
> }
> listener {
>     host: 0.0.0.0
>     *port: 5673*
>     authenticatePeer: no
>     saslMechanisms: ANONYMOUS
> }
> {noformat}
> qdrouterd logs the port as such:
> {noformat}
> CONN_MGR (info) Configured Listener: 0.0.0.0:5673 proto=any, role=normal
> {noformat}
> When specifying port 0, so that the dispatch router runs on a random 
> available port, the log is as such:
> {noformat}
> CONN_MGR (info) Configured Listener: 0.0.0.0:0 proto=any, role=normal
> {noformat}
> qdrouterd process can log instead the real port that was randomly chosen.
