Step 1: Connect your Imaging Server to the network
•!Connect your Imaging Server, , to a network port in the same subnet as the machines you will be
imaging
•"Let the TCP/IP address be set from your local DHCP server if you are on a live network
" • If you are on an isolated network you will need to setup a static IP address and configure DHCP
to deliver addresses to your client machines.
•"Open Server Admin and select the appropriate NetBoot image to boot your client machines from
Step 2: Setup your Multicast Server (via terminal)
•"Open Terminal on your Imaging Server
•"Create the configuration “.plist” file for your Multicast stream
" • Type: defaults write /Users/admin/Destktop/asr “Data Rate” -int 4000000
" • Hit Return
" • Type: defaults write /Users/admin/Desktop/asr “Multicast Address” 224.77.2.2
" • Hit Return (This file can be saved and reused. You do not have to re-create this every time you image)
•"Start the Multicast Server"
" • Type: sudo asr -source /Volumes/storage/dmgshare/Custom/iLife05_OSX_10.4.7_G3.dmg -server
/Users/admin/Desktop/asr.plist
" • Hit Return (this command can be saved as a script, and ran anytime, without typing it in
•"Your Multicast Server is now fully configured, and started up. The multicast stream does not start until the server is contacted by
the first client
Optional Set 2: Use the GUI tool Proton Pack Server to initiate the multi-cast stream (see
Keith)
Step 3: Connect your Client machines to the network and boot them
up
•"Plug client machines into the network with an Ethernet cable
•"Make sure they are on the same subnet
•"Boot all clients while holding down the “N” key
Step 4: Image Client machines via Multicast ASR
•"Open Apple Remote Desktop on your Imaging Server
•"Click “Scanner” and find your NetBooted client machines
•"Select them all and click “Send Unix”
•"Type the following command in the Unix command window:
# asr -source asr://[ip address of multicast server] -target /Volumes/Macintosh_HD -erase -ver-
bose -noprompt
•"Run Command as “root”
•"Check the “Display all output” box
•"Click “Send” when you are ready for the Multicast to begin
" • NOTE: if this fails, adjust your data rate, or correct other issue, then send the command:
" " diskutil eraseDisk “Journaled HFS+” Macintosh\ HD “disk0”
•"Monitor progress through ARD “Send Unix Command” status window
