Continue with “Initiating a Multicast Session from Each Client” on page 427 .
Initiating a Multicast Session from Each Client
You can use the bash prompt or the ZENworks Imaging Engine menu to perform the multicast
session as you physically visit each device.
The following sections contain additional information:

Using the Bash Prompt to Perform the Multicast Session
1 (Optional) Install the Novell ZENworks Linux Management Imaging Agent ( novell-zislnx ) on
each of the participating devices.
If you do not install the Imaging Agent on each participating device, the devices have duplicate
network identities. For more information, see
“Limitations of Multicasting Images” on
page 342 .
2 Create an imaging boot CD or DVD for each person who will assist with the multicast session,
or enable PXE on the participating devices.
If you don’t know how to do this, see
Section 29.2, “Setting Up the Preboot Services
Methods,” on page 346 .
3 At each device, including the master device (unless you are starting the multicast session from
the imaging server), access a Linux prompt by using the imaging boot CD or DVD, or if it is
PXE-enabled, boot it.
4 Enter
manual
at the bash prompt.
5
To identify each participating device in the multicast session, enter the following command at
the bash prompt of every device:
img session session_name
where session_name is any string that uniquely identifies this multicast session from other
multicast sessions that might be in progress on the network. Use the same session name on each
of the participating devices in this multicast session. You can specify any multicast session,
including one that originates from the imaging server (as long as you specify the session name
used by the imaging server).
Example:
img session mcast01
