2. Restoring notes
1.1 Configured network at first boot
RedHat and Fedora use some files to configure the network at first boot. These files are located under “/etc/sysconfig/network-scripts/”.
At first boot of any of these servers after the restoration from tar files [link], the “ifcfg-ethX” configuration files are moved to a new file called ifcfg-ethX.bak, even if you have previously changed the hardware address of the corresponding NIC (Network Interface Controller) in the file.
This issue is not important in case of you can physically access the machine to rename back the “ifcfg-ethX.bak” file to “ifcfg-ethX”. But in our case, we will not be able to access the machine physically, and we will not be able to remotely access it until the network is configured.
This is why this step has to be done with high priority, otherwise we will never know if the machine booted and access it.
1.1.1 Correctly configure network scripts
After having untar all files in the new created partitions from your running Fedora or Debian distribution and before rebooting on the new partitions, configure the network scripts for the new system you just installed.
1.1.1.1 Get all data from ifconfig (including the VLANs if you have. If you are restoring on OVH, you HAVE to configure VLANs on your running distribution.

1.1.1.2 And past them into the configuration files of the “/etc/sysconfig/network-scripts/” of the mounted new partitions.
# vi /mnt/root1/etc/sysconfig/network-scripts/ifcfg-eth0
--------------------------------------------------------
DEVICE=eth0
BOOTPROTO=static
BROADCAST=xxx.xxx.xxx.255
IPADDR=xxx.xxx.xxx.99
HWADDR=00:15:F2:5D:DE:9F
NETMASK=255.255.255.0
NETWORK=xxx.xxx.xxx.0
ONBOOT=yes
TYPE=Ethernet
# vi /mnt/root1/etc/sysconfig/network-scripts/ifcfg-vlan5
--------------------------------------------------------
VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
DEVICE=vlan5
PHYSDEV=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
IPADDR=xxx.xxx.xxx.86
NETMASK=255.255.255.255
# vi /mnt/root1/etc/sysconfig/network-scripts/ifcfg-vlan6
--------------------------------------------------------
VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
DEVICE=vlan6
PHYSDEV=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
IPADDR=xxx.xxx.xxx.62
NETMASK=255.255.255.255
1.1.2 Script for moving ifcfg-eth0.bak file to ifcfg-eth0
1.1.2.1 Create the script in order to move “ifcfg-eth0.bak” to “ifcfg-eth0”.
# vi /mnt/root1/root/network-reconf-first-boot.sh
--------------------------------------------------------
#!/bin/bash
if [ -f /etc/sysconfig/network-scripts/ifcfg-eth0.bak ]
then
mv /etc/sysconfig/network-scripts/ifcfg-eth0.bak /etc/sysconfig/network-scripts/ifcfg-eth0
/etc/init.d/network restart
fi
exit 0
1.1.2.2 Program the script to be launched at booting
# chmod +x /mnt/root1/root/network-reconf-first-boot.sh
# vi /mnt/root1/etc/rc.d/rc.local
--------------------------------------------------------
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/root/network-reconf-first-boot.sh
Then you can reboot on hard disk.
If you’re installation is local, plug the RJ45 into the trunked Cisco port.
