    Can't connect using JMX remote - WIldfly 8.2.0.Final

      Followed what's mentioned in this document http://jaitechwriteups.blogspot.com/2014/12/remote-jmx-access-to-wildfly-or-jboss.html and this SO post http://stackoverflow.com/questions/22212693/wildfly-8-final-jconsole-cant-connect-remotely and others, all of which essentially said that if I followed the following steps, I'd be able to connect using the JMX console. Well, that's not the case.

       

      1. Create a management user by running add-user.sh. Check, created a user 'jmx-admin' not assigned to any groups.
      2. Check if able to log in to the admin console using the previously created user. Check, able to to log into http://127.0.0.1:9990/console just fine.
      3. Either mess with classpath or run bin/jconsole.sh. Check, ran the later.
      4. Connect using the connection string service:jmx:http-remoting-jmx://localhost:9990. Check. Also tried by relacing localhost with 127.0.0.1 and hostname.
      5. Connecion should be successful. Nop, connection failed.

       

      Few things that I'd like to mention here:

      1. As with most tech articles, none on this topic are up-to-date. What they fail to mention is if the management user needs to be associated with any group. Also on the version that I'm running, adding a user ends with a question "Is this new user going to be used for one AS process to connect to another AS process? e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls." that I answered negative to.
      2. $ hostname prints archlinux. If it matters (shouldn't but...) this is a virtual archlinux install.
      3. $ sudo cat /etc/hosts

       

      127.0.0.1 localhost

      127.0.1.1 archlinux

       

      127.0.0.1       localhost.localdomain   localhost

      ::1             localhost.localdomain   localhost

       

        4.  standalone.xml snippet (nothing changed, AS-IS):

       

      <interfaces>

              <interface name="management">

                  <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>

              </interface>

              <interface name="public">

                  <inet-address value="${jboss.bind.address:127.0.0.1}"/>

              </interface>

              <!-- TODO - only show this if the jacorb subsystem is added  -->

              <interface name="unsecure">

                  <!--

                    ~  Used for IIOP sockets in the standard configuration.

                    ~                  To secure JacORB you need to setup SSL

                    -->

                  <inet-address value="${jboss.bind.address.unsecure:127.0.0.1}"/>

              </interface>

      </interfaces>


        5.  $ ifconfig
