By default, only Rhino’s management tools (such as the command-line console or stats console) can run on the same host as Rhino. You can, however, securely manage Rhino from a remote host.

As discussed in the preceding topic, Rhino uses SSL to secure its interconnect with management clients. To configure Rhino to support remote management clients:

  1. Copy the client directory to the remote machine.

  2. Allow the remote host to connect to the JMX remote adaptor.

Set up the client directory on the remote machine

The client directory (and subdirectories) contain all the scripts, configuration files and other dependencies needed for Rhino management clients. To setup the client directory on the remote machine:

  1. Copy the entire directory structure to the remote host: $ scp -r client <user>@<host>:<destination>/

  2. Edit client/etc/client.properties and change rhino.remote.host:

    # RMI properties, file names are relative to client home directory
rhino.remote.host=<rhino host>
rhino.remote.port=1199
# ...

Allow the remote host to connect to the JMX remote adaptor

All management tools connect to Rhino using the JMX Remote Adaptor m-let. By default this component only permits access from the same host that Rhino is running on.

The security-spec section of the node-XXX/config/permachine-mlet.conf and node-XXX/config/pernode-mlet.conf files defines the security environment of an m-let. To allow a remote host to connect to the JMX remote adaptor, edit the security-permission-spec sections of the node-XXX/config/permachine-mlet.conf file, to enable remote access with appropriate java.net.SocketPermission:

<mlet enabled="true">
<classpath>
<jar-url>@FILE_URL@@RHINO_BASE@/lib/jmxr-adaptor.jar</jar-url>
<security-permission-spec>
grant {
...
permission java.net.SocketPermission "<REMOTE_HOST>","accept";
...
};
...
</mlet>
Warning If you would like to connect to Rhino SDK, the file that defines the m-let configuration is $RHINO_SDK/config/mlet.conf.
