Clone Systems

The 2 HDD in one System Approach

master disk: /dev/hda

clone disk: /dev/hdc

fdisk /dev/hdc

copy directories to /dev/hdc

mount /dev/hdc1 /mnt/hdc1 cd / ; tar cf - boot root bin sbin etc dev lib var usr \ | ( cd /mnt/hdc1 ; tar xvfp - )

change specific parameters on the clone (IP, ...)

run lilo to make the clone bootable ( i just use a boot floppy to boot the clone )

The Over the Network Approach

On the receiver:

nc -p 6666 -l > file

or:

nc -p 6666 -l -v -w 60 < /dev/null | gzip -dc | dd of=/dev/hda bs=512

On the sender:

cat data | gzip -c | nc -v -w 120 -p 6666 -l IP

or:

dd if=/dev/hda1 bs=512 | gzip -c | nc -v -w 60 IP -p 2020

On a Windows sender:
dd.exe if:\\.\C: bs=512 | nc.exe a.b.c.d port
