CentOS 6.5 网卡安装报"Error, some other host already uses address"的解决方案

解决办法:

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

注解掉下面的几行内容,然后再执行ifup eth0

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  
fi  

改为

#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  
#fi
