=== Socket Port Bindings

The ports opened for each socket have a pre-defined default that can be overriden at the command line or within configuration.
To illustrate this configuration, let's pretend you are running in <<fake/../../operating-mode/standalone.adoc#_standalone-mode,standalone mode>> and
open up the _.../standalone/configuration/standalone.xml_.  Search for `socket-binding-group`.

[source,xml]
----
    <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
        <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
        <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9993}"/>
        <socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
        <socket-binding name="http" port="${jboss.http.port:8080}"/>
        <socket-binding name="https" port="${jboss.https.port:8443}"/>
        <socket-binding name="txn-recovery-environment" port="4712"/>
        <socket-binding name="txn-status-manager" port="4713"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>

`socket-bindings` define socket connections that will be opened by the server.  These bindings specify the
`interface` (bind address) they use as well as what port number they will open.   The ones you will be most interested in are:

http::
   Defines the port used for {{book.project.name}} HTTP connections
https::
   Defines the port used for {{book.project.name}} HTTPS connections
ajp::
   This socket binding defines the port used for the AJP protocol.  This protocol is used by Apache HTTPD server
   in conjunction `mod-cluster` when you are using Apache HTTPD as a load balancer.
management-http::
   Defines the HTTP connection used by {{book.appserver.name}} CLI and web console.

When running in <<fake/../../operating-mode/domain.adoc#_domain-mode,domain mode>> setting the socket configurations
is a bit trickier as the example _domain.xml_ file has multiple `socket-binding-groups` defined.  If you scroll down
to the `server-group` definitions you can see what `socket-binding-group` is used for each `server-group`.

        <server-group name="load-balancer-group" profile="load-balancer">
            ...
            <socket-binding-group ref="load-balancer-sockets"/>
        </server-group>
        <server-group name="auth-server-group" profile="auth-server-clustered">
            ...
            <socket-binding-group ref="ha-sockets"/>
        </server-group>
    </server-groups>

NOTE:  There's a lot more nifty options when setting up `socket-binding-group` definitions.  See the link:{{book.appserver.socket.link}}[the socket binding group]
       chapter of the {{book.appserver.socket.name}}.
