HTTP and HTTPS ports are controlled, in Karaf and Fabric by these pids:
org.ops4j.pax.web.cfg/org.osgi.service.http.port
org.ops4j.pax.web.cfg/org.osgi.service.http.port.secure
So you should always set your desired values, via ConfigAdmin or configuration, to those pids.
These values are used by pax-web project to inject programmatically connectors for you.
Be aware that you can ADD additional connectors, directly in jetty.xml configuration.
The suggestion is to comment out or completely remove that <Set/> node from you jetty.xml and to use only ConfigAdmin to control that value.
The default port for sshd embedded service is 8101 and it's default value is present in both the ssh feature definition and in an explicit OSGi config file:
etc/org.apache.karaf.shell.cfg
Either change it directly in the file, or with usual ConfigAdmin operations (that will persist it on the same file, anyway.)
RMI port is defined in this file etc/org.apache.karaf.management.cfg. Notice that the rmiRegistryPort variable is used in the composite serviceUrl variable, so be careful regarding which one you modify.
--minPort and --max-port are parameters that you can specify at fabric:create and fabric:join time to influence the ports chosed by the managed services running on your container.
NOTE:
The range is going to be used for the new services that will be created and deployed on the container, like Zookeeper for examples and others.
But it will not affect already running services, that came from the Standalone instance. Most notably: http/https, jmx, ssh. To change this "pre-existing" assignment you still have to pass through usual OSGi-ConfigAdmin options.
