Name
zmd - The back-end daemon for the Novell
®
ZENworks
®
Linux Management agent.
Syntax
zmd [options]
Description
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 initiated through the
ZENworks Control Center or the rug, zen-installer, zen-updater, or zen-remover utilities, which
means you should not need to interact directly with zmd.
The zmd daemon has built-in download interrupt support. If a download is interrupted, the zmd
daemon resumes the download where it left off.
While making the HTTP requests, the zmd agent sets the HTTP User-Agent value to ZENworks
Management Daemon/<
version >, where < version > is a value as reported by the
rug ping
command.
The Device Black-Out feature of ZMD allows you to configure the following preferences:
Š
blackout-interval “< start_time > - < end_time >”: The time interval for which the device is to
be locked. Specify the start time and end time in the HH:MM format, with hours in 24-hour
format. For example, if the device is to be locked from 9 a.m. to 6 p.m., specify the time
interval as 09:00-18:00.
Š
device-locked: Valid values are “True” and “False”. If the device-locked value is set to True,
then zmd blocks install, removal, refresh, and register operations for packages and bundles.
However, we recommend that you do not manually change the value of device-locked. The
value is automatically set when you configure blackout-interval to specify the time interval
when the device is to be locked. Depending on blackout-interval, the lock or unlock schedule is
created and triggered. The lock or unlock schedule resets the device-locked value accordingly.
If any refresh, bundle install, or bundle remove schedules are to be triggered when the device is
locked, then these schedules are rescheduled to be triggered after the device is unlocked.
