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

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.localdomain localhost
::1		localhost6.localdomain6 localhost6
10.1.1.10 source-int source
10.1.1.11 target-int target

4. Set the network address for eth1

cd /etc/sysconfig/network-scripts
vi ifcfg-eth1

Change the settings to the following

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
HWADDR=08:00:27:19:c2:f8
IPADDR=10.1.1.10
NETMASK=255.255.255.0

5. Restart the network interface

[root@source network-scripts]# /etc/init.d/network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down interface eth1:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]

There are 2 network interfaces:

a) eth0 which is a DHCP address so that a connection can be made from the host computer (your laptop). In this case the IP is 10.0.0.20

b) eth1 which is a fixed IP address. This is used to connect between the source and target servers. This IP is 10.1.1.10

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"
