<br clear="all"></blockquote><br>Provided you're on a switched network (as everyone is these days), the 'nettee' utility is great for these situations. The disk image to be cloned will get out to the network just once, so you'll not consume 12x time to stream an image. The trick is to build a virtual chain with the stations, giving each nettee process the next host's ip address. Nettee behaves like a 'tee' command but spits output to the network.
<br><br>- download nettee utility to your source machine (there is a DAG RPM package)<br>- on your destination hosts, boot with installation disks in rescue mode or use a tool as System Rescue CD (you can eject it and proceed to next host)
<br>- copy nettee to the destination hosts<br>- on your source machine do dd if=/dev/sda | nettee -in - -next my_next_host_ip<br>- on all your destination machines but the last, do nettee -out - -next my_next_host_ip | dd of=/dev/sda
<br>- on the last, nettee -out - | dd of=/dev/sda<br><br>Of course you will want to look at nettee's man page to verify my syntax and usage. Here my_next_host_ip is always changing, as it is the IP address of the next host in the virtual chain nettee will create. This example assumes you want to clone /dev/sda on source to /dev/sda on every other host. Nettee has many other features, well worth a look.
