NETWORKING HACK

cloning disks over the network
I needed to clone a number of notebook hdd's for a small rollout. I'm a lazy bastard so I thought the easiest way to do this was over the LAN.

First boot up the target machine, you need have an sshd daemon running on the target machine with a network interface. In my case I used the gentoo linux bootable cd.

start the sshd daemon with
#/etc/init/sshd start
you will also need to change the root passwd
#passwd
If you need more info RTFM.

next bootup the machine you are going to clone, login as root and type the following

#dd if=/dev/hda bs=10k | ssh $TARGET_IPADDRESS
\ dd of=/dev/hda bs=10k

Wait a couple of hours and your done.

Note: The drive geometry needs to be exactly the same. There are probably better ways to do this.
