#自动拨号脚本由本人制作QQ:12956620
#请把dns1,dns2修改成拼得通的DNS,开机自动运行,实时监控,断线自动重拨

sleep 12
while true
do
ping -s 1 -c 1 $dns1 ……去PING第一个DNS
if [ "$?" != "0" ] ……假如PING不通
then
ping -s 1 -c 2 $dns2 ……去PING第二个DNS
if [ "$?" != "0" ] ……假如PING不通
then
killall pppd ……结束PPPD进程
pppd call gprs-siem & ……再去拨号
sleep 12 ……等待12秒
else
sleep 5 ……如果是PING DNS2通的话就直接等待5秒
fi
else
sleep 5 ……如果是PING DNS1通的话就直接等待5秒（一般要设置多长时间去PING请改这里）
fi
done
代码简明！！它相当于在后台时时去PING一个DNS发现真正地掉线，它才会去重新拨号！！此版本经测试通过才发表。
