Cloning the Linux Machine through Network
Release:
Redhat Enterprise Linux
CentOS
Fedora
Problem:
Ghosting the Linux server without third party software
Solution:
Assumption:
a) New server ipaddress 172.16.1.247
b) Running server ipaddress 172.16.1.248
In new machine side Configuration:
1) Booted into the rescue mode
2) Enable the networking option
3) Give the below command to make dd command listening to port 30 for input,
# nc -l -p 30
dd of=/dev/sda
In running server side configuration:
4) Dump the content of the disk to the target pc though port 30 using the following command,
# dd if=/dev/sda
nc 172.16.1.247 30
5) Then to check that traffic is flowing, on the source machine go to another terminal (ALT/F2) and dump the tcp data on the NIC (assuming it's eth0)
# tcpdump -tnli eth0 port 30
Note: Assuming that Network controller driver is available in default OS Kernel.
