rug is the command line frontend to zmd. It does no actual work except for issuing commands to zmd and reporting to the user the status of the command.

You can use rug  for installing patches and updates. For full documentation see man rug.

To install updates with rug:

First you need to check if zmd is running. To do this try rug ping:

$ rug ping
ZMD 7.1.1, Copyright (C) 2006 Novell, Inc.
Started at 7/17/2006 2:47:39 PM (uptime: 1 days, 0 hours, 38 minutes)
RSS size: 42252
Network Connected: Yes
Running on Mono

OS Target: SUSE Linux Enterprise Server 10 (i586)

Module Name        | Description
NetworkManager     | NetworkManager support
Package Management | Package Management module for Linux
ZENworks Server    | SOAP methods used by a ZENworks server
XML-RPC interface  | Export ZMD public interfaces over XML-RPC

If zmd isn't running you'll get a message like this:

$ rug ping
ERROR: ZMD does not appear to be running.

In that case you must be root and do % rczmd start.


Adding a service

Before we can install any packages we must first add a service. To do this you must generally be root or run the command with sudo. The general syntax is:

$ rug service-add --type=zypp URL unique-name

So, to use the SUSE mirror, you can do:

$ rug sa --type=zypp factory

Adding ZYPP service

Now let's check what services zmd is using:

$ rug service-list

# | Status | Type | Name      | URI
1 | Active | ZYPP | factory   |

Renaming a service

Subscribing to a catalog

It is not enough to simply add a service and start installing packages. Services may contain one or more catalogs. Think of services as a repository of catalogs and catalogs as a repository for packages and patches. Let's see what catalogs we have available:

$ rug catalogs

Sub'd? | Name      | Service
       | factory   | factory

Great, we have the "factory" catalog from our "factory" service that we added earlier. Now we can subscribe:

$ rug subscribe factory
Subscribed to 'factory'

Finding, Installing, Upgrading, and Removing Packages

Now that we have a catalog which we are subscribed to we can install some packages. For a lot of these commands you usually need to be root or run them with sudo. There is this great program I like called boo for mono. I'm not sure what the package name is. Let's find out:

$ rug search boo

S | Catalog | Bundle | Name                            | Version     | Arch
  | factory |        | boo                             |     | noarch

Sweet the package name is "boo" time to install it:

$ rug install boo
Resolving Dependencies...

The following packages will be installed:
  boo (


Transaction Finished

Great now I can write sweet boo programs. *5 years pass* Oh it's been 5 years! I need to upgrade boo. Fortunately the same command "install" is used for both upgrading a previously installed package and installing a package for the first time.

$ rug install boo
Resolving Dependencies...

The following packages will be installed:
  boo (


Transaction Finished

Now I have version of boo! Unfortunately, after five years, I've stopped programming in boo, I'd rather just use Perl 6 on Parrot. I need to get rid of it:

$ rug remove boo
root's password:
Resolving Dependencies...

The following packages will be removed:
  boo (system)


Transaction Finished

Doing More, Getting Help

rug is a robust program with many commands and options. To get a list of available commands try:

$ rug --help

To get help on any specific command try:

$ rug <command> --help


Manpage of zmd

Content-type: text/html


Section: Software management daemon (8)
Updated: 1.0


zmd - The backend daemon for the Novell ZENworks Linux Management Agent.  


/etc/init.d/novell-zmd [start|stop|restart] <options>
zmd <options>  


The zmd daemon performs software management functions on the ZENworks managed device, including updating, installing and removing software and performing basic queries of the device's package management database. Typically, these management tasks are initiatied through the ZENworks Control Center or the rug utility, which means you should not need to interact directly with zmd.

The daemon is kept apart from the control application so that the control application can be used to administer remote systems. See the rug man page for more information about this process.  



-n, --non-daemon
Do not run the daemon in the background.
-m, --no-modules
Do not load any optional modules.
-r, --no-remote
Do not listen for remote connections. This means that the daemon can only be controlled from the local system.
Don't load the saved services. .LP HELP OPTIONS
--help, -?
Display the help information and exit.


Configuration file. Options such as proxy and cache settings can be adjusted through this file directly or with the rug set command.


Initialization script. It is recommended that you use this script to start and stop zmd, rather than running it directly.


Log file.


Cached information from servers.


Url for the ZENworks service that zmd will use at initial startup. You can optionally specify a registration key on the next line.




This program normally runs as root.


To run this program the standard way type:
/etc/init.d/novell-zmd start
Alternatively, run the program directly:
