Update From The Command Line With Rug - Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 08-05-2008 Installation Manual

-s, --no-services
Do not load initial services.
-r, --no-remote
Do not start remote services.
ZMD configuration is stored in /etc/zmd/zmd.conf. You can change the configu-
ration manually or with rug. The URL for the ZENworks service that zmd uses at
initial start-up and a registration key are stored in /var/lib/zmd. Updates are
downloaded to the ZMD cache in /var/cache/zmd.
ZMD is the back-end only. The software management tasks are initiated through the
command line tool rug or the graphical Software Updater applet.
9.1 Update from the Command Line
rug uses the zmd daemon to install, update, and remove software according to the
commands given. It can either install software from local files, or from servers. You
may use one or more remote servers, known as services. Supported services are mount
for local files, and yum or ZENworks for servers.
rug sorts software from services into catalogs (also known as channels), which corre-
spond to groups of similar software. For example, one catalog might contain software
from an update server as well as software from a third-party software vendor. You are
able to subscribe to individual catalogs in order to control the display of available
packages and prevent the accidental installation of unwanted software. Operations
usually are performed only on software from catalogs to which you are subscribed.
9.1.1 Obtaining Information from rug
rug provides a wide range of useful information. It allows you to check the status of
zmd, view registered services and catalogs, or see information about available patches.
If the zmd is not used for a certain period of time, it can be switched to sleep mode. To
check the zmd status and reactivate the daemon, use rug ping. This command wakes
zmd up and logs its status information.
