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
NETWORKING_IPV6=no
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. Set the network address for eth0

cd /etc/sysconfig/network-scripts
vi ifcfg-eth0

Change the settings to the following (do NOT change the HWADDR)

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
ONBOOT=yes
HWADDR=08:00:27:18:b5:af
BOOTPROTO=none
IPADDR=10.0.2.4
NETMASK=255.255.255.0
GATEWAY=10.0.2.1
NETWORK=10.0.2.0

 

5. Restart the network interface

# /etc/init.d/network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:                                [  OK  ]

 

6. View the network interface

# ifconfig

          inet addr:10.0.2.4  Bcast:10.0.2.255  Mask:255.255.255.0

There is only one network interfaces:

  • 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.

7. 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"
  • No labels
