oracle linux6.3下遇到some other host already uses adress

oracle linux6.3下遇到some other host already uses adress，解决过程：

配置网络如下：

[root@tandb1 ~]# more /etc/hosts

127.0.0.1   localhost.localdomain localhost

::1         localhost6 localhost6.localdomain6

192.168.33.247   tandb1

[root@tandb1 ~]# cd /etc/sysconfig/

[root@tandb1 sysconfig]# more network

NETWORKING=yes

HOSTNAME=tandb1

gateway=192.168.33.254

[root@tandb1 sysconfig]# cd network-scripts/

[root@tandb1 network-scripts]# more ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

ONBOOT="yes"

IPADDR=192.168.33.247

NETMASK=255.255.255.0

[root@tandb1 network-scripts]#

重启网络：

# service network restart

遇到下面的错误：

some other host already uses adress

解决办法:

vi /etc/sysconfig/network-scripts/ifup-eth

注解掉下面的几行内容,然后再重启网络

if ! /sbin/arping -q -c 2 -w 3 -D -I ${REALDEVICE} ${IPADDR} ; then 

  echo {1}quot;Error, some other host already uses address ${IPADDR}." 

  exit 1
