Log onto the VM 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
[root@localhost ~]# vi /etc/sysconfig/network
and change to:
NETWORKING=yes HOSTNAME=source
3. Edit /etc/hosts and add the following two hosts entries
# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost ::1 localhost 10.0.2.4 source-int source dbv01 10.0.2.5 target-int target dbv02
4. Right click on the Network Manager icon on the top right hand corner, and click on "Edit Connections..."
5. Click on Auto eth1 and click on "Edit..."
6. Select the "IPv4 Settings" tab. Set the Method to "Manual" and add following details:
Address: 10.0.2.4
Netmask: 24
Gateway: 10.0.2.1
DNS Servers: 8.8.8.8
Then click on Apply
7. View the network interface
# ifconfig

There is only one network interface:
- eth1 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 10.0.2.4.
8. Test if the network connection is working. Use Control-C to stop the ping.
# ping www.dbvisit.com PING dbvisit.com (67.222.54.241) 56(84) bytes of data. 64 bytes from 67-222-54-241.unifiedlayer.com (67.222.54.241): icmp_seq=1 ttl=47 time=190 ms 64 bytes from 67-222-54-241.unifiedlayer.com (67.222.54.241): icmp_seq=2 ttl=47 time=189 ms 64 bytes from 67-222-54-241.unifiedlayer.com (67.222.54.241): icmp_seq=3 ttl=47 time=192 ms 64 bytes from 67-222-54-241.unifiedlayer.com (67.222.54.241): icmp_seq=4 ttl=47 time=193 ms ^C
9. scp (secure copy) does not work because there is display output in ~oracle/.bashrc and ~oracle/.bash_profile. To fix this:
a. Edit .bashrc in the home directory of oracle
cd ~oracle
vi .bashrc
Put a # in front of the following lines:
#cat ~/Desktop/README.txt #/sbin/ifconfig | grep "inet addr"
b. Edit .bash_profile in the home directory of oracle
cd ~oracle
vi .bash_profile
Put a # in front of the following lines:
#echo IP Address is: #/sbin/ifconfig | grep "inet addr"
