C.7. Script de ejemplo de la API

This is a sample script for use of the experimental RHN Management APIs. #
The API is currently available using XMLRPC only, which is described in  #
depth at:                                                                #
                                                                         #
http://www.xmlrpc.com/                                                   #
                                                                         #
We use the Frontier modules, available from:                             #
                                                                         #

                                                                         #
  Defining an XMLRPC session.                                            #
Define the host first.  This will be the FQDN of your satellite system.
Now we create the client object that will be used throughout the session.
Next, we execute a login call, which returns a session identifier that will
be passed in all subsequent calls.  The syntax of this call is described at:
  http://$HOST/rpc/api/auth/login/
  System calls.                                                          #
This next call returns a list of systems available to the user.  The
syntax of this call is described at:
  http://$HOST/rpc/api/system/list_user_systems/
In the code snippet below, we dump data about our systems, and we
capture the ID of the first system we find for future operations.
This next call returns a list of packages present on this system.  The
syntax of this call is described at:
  http://$HOST/rpc/api/system/list_packages/
This will probably be a pretty long list.
Additional system calls are described at:
  http://$HOST/rpc/api/system/
