Previous step is here
When you select "Launch Console" a new browser window download a jnlp file. Click on the first button ("Conserva" in my language and with Chrome browser) and a java console will appear.
If you take a look at the status of network service you can see that only loopback interface is active. You can type also ifconfig command to see the same result: if you issue the ifconfig -a command you can see all the available interface, so eth0 appears as output.
We have now to modify the /etc/hosts file and change the template hosts file with the right one.
The following is my current hosts file, with the right IP address and hostname
Now rename the ifcfg-eth0.bak file in ifcfg-eth0
