Requirements

• Computer being captured has been added to the VCL database
• Computer has been installed with Linux
• Two network adapters are enabled on the computer:
  • eth0 - connected to the private network
  • eth1 - connected to the public network
• The ability to log in as root via SSH using an identity key on the private network from management node

Configure SSH Identity Key Authentication

1. On the Linux computer being captured, create a /root/.ssh directory:

   Tip
   mkdir /root/.ssh

2. On the management node, copy the public SSH identity key to the authorized_keys file on the Linux computer being captured:

   Tip
   scp /etc/vcl/vcl.key.pub <hostname or IP address>:/root/.ssh/authorized_keys

3. Or replace the above two steps with the following on the management node:

   Tip
   ssh-copy-id -i /etc/vcl/vcl.key <hostname or IP address>

4. Make sure you can login from the management node to the Linux computer being captured using the identity key:

   Tip
   ssh -i /etc/vcl/vcl.key <hostname or IP address>

Configure the ifcfg-* Files

1. Navigate to the network-scripts directory:

   Tip
   cd /etc/sysconfig/network-scripts

2. Delete any ifcfg-*.bak files:

   Tip
   rm -f /etc/sysconfig/network-scripts/ifcfg-*.bak

3. Edit every ifcfg-eth* file in the network-scripts directory. Remove the HWADDRESS= line:

   Tip
   vi ifcfg-eth0

   Tip
   vi ifcfg-eth1

   The ifcfg-eth0 file should contain the following:

   No Format
   DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes

   The ifcfg-eth1 file should contain the following:

   No Format
   DEVICE=eth1 BOOTPROTO=dhcp ONBOOT=yes

4. Reboot the computer:

   Tip
   shutdown -r now

5. Check the ifcfg-eth* files to make sure there are no ifcfg-eth* files and that the HWADDRESS= lines have not been automatically added back:

   Tip
   ls /etc/sysconfig/network-scripts

   Tip
   cat /etc/sysconfig/network-scripts/ifcfg-eth0

   Tip
   cat /etc/sysconfig/network-scripts/ifcfg-eth1
