How To Rename The Host and Change IP address

Sometimes host has to be renamed or IP address has to be changed. Please follow these steps.

1. Change the name under

[root@xxxxxx root]# more /etc/sysconfig/network-scripts/ifcfg-vswif0

DEVICE=vswif0

MACADDR=00:50:56:4f:65:19

PORTGROUP="Service Console"

BOOTPROTO=static

BROADCAST=xx.xx.xx.255

IPADDR=xx.xx.xx.xx

NETMASK=255.255.255.0

ONBOOT=yes

2. [root@xxxx root]# more /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=<Full DNS Name>

GATEWAY=XX.XX.XX.XX

GATEWAYDEV=vswif0

3. [root@xxxxxx root]# more /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

xx.xx.xx.xx %FQDN Name of the host% %NetBIOS name%

Best would be reboot the host.
