[网络协议]CentOS4添加定时任务_自动更新WAN口IP

#!/bin/bash
#/home/cabal/ip.sh
wan0=`curl icanhazip.com`
#获取WAN口公网IP
wan1=`awk -F '=' '/\[WorldSvr\]/{a=1}a==1&&$1~/IPAddress/{print $2;exit}' /etc/cabal/WorldSvr_24_01.ini`
#读取原ini文件中的IP
if [ "$wan0" != "" ]
	then
		if [ "$wan0" == "$wan1" ]
		then echo "WAN0"	
		exit
		else echo "WAN1"	
		sed /etc/cabal/Templates/WorldSvr_24_01.ini \
		-e "s/cip/$wan0/g" \
		> /etc/cabal/WorldSvr_24_01.ini.tmp
		mv /etc/cabal/WorldSvr_24_01.ini.tmp /etc/cabal/WorldSvr_24_01.ini
		service cabal restart
		exit
		fi
	else
	exit
fi
