[jboss-jira] [JBoss JIRA] (WFCORE-4763) interface "any" tag not working as expected

[Brian Stansberry (Jira)]

    [ https://issues.redhat.com/browse/WFCORE-4763?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13824156#comment-13824156 ] 

Brian Stansberry commented on WFCORE-4763:
------------------------------------------

A single interface resource in the configuration is meant to to produce a single InetAddress that other parts of the server can then use. The 'any' handling is working correctly in doing that -- as soon as it finds a criteria that generates an acceptable InetAddress available on the system, that is what it provides. The interface resource does not itself create a socket. Some other part of the system injects the InetAddress and creates a socket, and for whatever that is to listen on different addresses it would have to support injecting different multiple addresses. The management interface does not support that.

Supporting binding the management interface to multiple different addresses would be an RFE.

>             Project: WildFly Core
>          Issue Type: Bug
>          Components: Management

> The {{<any>}} tag in the {{interface}} configuration of {{standalone.xml}} should accept any connection that matches ANY of the provided rules. This is not the case as demonstrated by the example below.
> This configuration allows to run {{jboss-cli.sh -c}} from the machine where wildfly is running as expected:
> {code:xml}
>     <interfaces>
>         <interface name="management">
>             <any>
>                 <inet-address value="127.0.0.1"/>
>             </any>
>         </interface>
>     </interfaces>
> {code}
> But if I add another (VALID) IP address inside the any tag, I can't connect any more:
> {code:xml}
>     <interfaces>
>         <interface name="management">
>             <any>
>                 <inet-address value="127.0.0.1"/>
>                 <inet-address value="10.20.230.26"/>
>             </any>
>         </interface>
>     </interfaces>
> {code}
> With the latter configuration, {{connect}} fails with the following error:
> {noformat}
> >The controller is not available at localhost:9990: java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: Connection refused
> {noformat}
> Note: to easily reproduce the problem from the cli, starting from a fresh standalone install:
> {code:bash}
> connect
> /interface=management:undefine-attribute(name=inet-address)
> /interface=management:undefine-attribute(name=any)
> /interface=management:write-attribute(name=any,value={inet-address=[127.0.0.1]})
> reload
> /interface=management:write-attribute(name=any,value={inet-address=[127.0.0.1,10.20.230.26]})
> reload
> {code}
> Notes:
> - 10.20.230.26 must be a reachable IP - if I use a random one I can connect normally.
> - if I use {{subnet-match}} I get the same issue
