Copy etc/sysconfig/network-scripts/ifcfg-eth0 file as /etc/sysconfig/network-scripts/ifcfg-eth0:0
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:0
Open file /etc/sysconfig/network-scripts/ifcfg-eth0:0 using vi text editor:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
Find entry that read as follows:

DEVICE=eth0

Replace with:

DEVICE=eth0:0

Find entry that read as follows:

IPADDR=xxx.xxx.xxx.xxx

Replace it with your actual IP address:

IPADDR=200.200.200.1

At the end your file should like as follows:

DEVICE=eth0:0
IPADDR=200.200.200.1
NETMASK=255.255.255.0
NETWORK=200.200.200.0
ONBOOT=yes
NAME=eth0:0

Open file /etc/sysconfig/network-scripts/ifcfg-eth0 and make sure file does not have a GATEWAY= entry:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
Find the entry that read as follows:

GATEWAY=your-ip

Remove or comment it out by prefixing # (hash) :

 # GATEWAY=200.200.200.254

Save the file. Add the GATEWAY= to your /etc/sysconfig/network:

# vi /etc/sysconfig/network

Append or modify GATEWAY entry:

GATEWAY=200.200.200.254

Save the file. Reboot the system or run the following command:

# ifup eth0:0

OR

# service network restart

What is safe mode?

Safe mode.

Safe mode is a troubleshooting option for all the Operating System.It starts your computer in a limited state. Only the basic files and drivers necessary to run the Operating System are started. An operating system in safe mode will have reduced functionality, but the task of isolating problems is easier because many non-core components are disabled.Safe mode typically provides access to utility and diagnostic programs so a user can troubleshoot what is preventing the operating system from working normally. Safe mode is intended for maintenance, not functionality, and provides minimal access to features.Microsoft Windows' safe mode is accessed by pressing the F8 key as the operating system boots.An equivalently minimal setting in Unix-like operating systems is single-user mode.On Mac OS versions 6, 7, 8 and 9, a similar mode is achieved by holding down theshift key while booting.

                                                       Safe mode in Windows
