6.1 ZENworks Agent (zmd)
The ZENworks Agent is named zmd. It is sometimes referred to as the ZENworks Management
Daemon (zmd).
The ZENworks Agent 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 initiated through the
ZENworks Control Center or the
rug
utility, which means you should not need to interact directly
with the ZENworks Agent.
The ZENworks Agent is installed to the following directory:
/opt/novell/zenworks/sbin
For SUSE LINUX Enterprise Server 10 (SLES 10) and SUSE LINUX Enterprise Desktop 10
(SLED 10) devices, the ZENworks Agent is located in the following directory:
/usr/sbin
6.1.1 ZENworks Agent (zmd) Cache Settings
As the ZENworks Agent (zmd) performs its duties, it maintains a cache that stores the content of
bundles that are downloaded for installation on that managed device. You can control the age of
contents in the cache and its size by using cache settings. Cache cleanup is enforced on both client
startup and refresh.
If the process of downloading the bundle is interrupted on the managed device, the zmd starts the
download of individual packages from where it was left off.
The cleaning of cached information is always enabled. You can configure the following settings
using the
rug set
command in the
rug
utility to manage the cache. For more information about the
rug utility, see Section 4.4, “rug,” on page 46 .
