session Examples
Parameter Specifies
name The name of the multicast session. Each device joining the session uses the same
value for this parameter.
IMPORTANT: The name must be unique among concurrent multicast sessions. It
is hashed by the ZENworks Imaging Engine to produce a Class D IP address for
the multicast session. To facilitate troubleshooting (wire sniffing), all Linux
Management imaging multicast addresses start with 231. For example, the
session name
mcast01
can produce the multicast address 231.139.79.72.
master|client Specifies that this device is the session master or a session client.
If you omit this parameter, the ZENworks Imaging Engine waits for the user at the
master device to press
m
to designate that device as the master, or it waits for
another device to be declared master for the imaging session to be started from
the imaging server by selecting
Manually start multicast , providing the required
information, then selecting Yes .
clients= count The number of participating devices that must register with the master before
imaging begins. This option only applies to session masters.
If you omit this parameter, the ZENworks Imaging Engine waits for the user at the
master device to press
g
. After imaging has begun, any participating devices
attempting to register are denied.
time= minutes The number of minutes the master device waits for the next participant to register
before starting the imaging process without reaching
count registered participants.
This option only applies to session masters.
If you omit this parameter, the imaging process does not start until count is
reached, or the user at the master device presses
g
. After that, any participants
attempting to register are denied and queued for the next multicast session.
Example Explanation
img session mcast01
Starts a multicast session named
mcast01
. Each
successive device that issues this same command before
the imaging begins joins the session. Imaging doesn’t start
until one of the users presses
m
to designate himself as
master and presses
g
to start the imaging, or the imaging
session is started from the imaging server by selecting
Manually start multicast , providing the required
information, then selecting Yes .
