How To Rename The Host and Change IP address

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

  1. [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.
