Log onto the second VM (dbv02) through the VirtualBox console which will be shown when the VM has started. 

The username is root and the password is oracle

1. When logged onto the desktop, right click and click on "Open Terminal" to bring up the terminal.

2. In the terminal edit  /etc/sysconfig/network

vi /etc/sysconfig/network

and change to:

NETWORKING=yes
HOSTNAME=target

3. Right click on the Network Manager icon on the top right hand corner, and click on "Edit Connections..."

4. This brings up the Network connections.

5. Select "Auto eth1" and select "Delete...". This interface is no longer required. 

6. Select "Auto eth2" and click on "Edit...".

7. Select the "IPv4 Settings" tab. Set the Method to "Manual" and add following details (click on "Add" to add the details):

Address: 10.0.2.5

Netmask: 24

Gateway: 10.0.2.1

DNS Servers: 8.8.8.8

Then click on Apply

8. View the network interface

ifconfig
eth2      Link encap:Ethernet  HWaddr 08:00:27:C8:DC:F6  
          inet addr:10.0.2.5  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::a00:27ff:fec8:dcf6/64 Scope:Link

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:340 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0 
          RX bytes:22444 (21.9 KiB)  TX bytes:22444 (21.9 KiB)

There is only one network interface:

  • eth2 which is a fixed IP address. This is used to connect between the source and target servers and also to the Internet. This IP is 10.0.2.5.

9. Test if the network connection is working. Use Control-C to stop the ping.

ping www.dbvisit.com

10. Shutdown the VM (dbv02).

# shutdown -h now

11. Start the first VM (dbv01) again by clicking on "Start".

12. Start the second VM (dbv02) by clicking on "Start".

13. Both VMs should now be running with the correct hostnames (source and target).
