今天公司同事要我整个adsl自动重拨的shell,并检测是否连上了,这样才能保证内部测试服务器不掉网,好吧,下面我把脚本发出来.

系统:centos 5.x

脚本1:

cat /root/soft_shell/auto_adsl_1.sh 

#!/bin/bash

gateway=`ifconfig ppp0 |grep P-t-P| cut -f 3 -d ":"|cut -f 1 -d " "`

inter=`ifconfig |grep ppp0|awk '{print $1}'`

N=2

if [[ $inter -eq ppp0 ]]

then

/sbin/adsl-stop

sleep 10 

/sbin/adsl-start

sleep 20

pkgloss=`ping -c4 $gateway|grep 'transm' |awk -F',' '{print $2}' |awk '{print $1}'`

if [[ $pkgloss -lt $N ]]

then

echo "`date +%Y-%m-%d/%T` The network is not stable">>/root/adsl.txt

else

echo "`date +%Y-%m-%d/%T` The network is normal">>/root/adsl.txt

fi

fi

cat /root/soft_shell/auto_adsl_2.sh 

#!/bin/bash

gateway=`ifconfig ppp0 |grep P-t-P| cut -f 3 -d ":"|cut -f 1 -d " "`

inter=`ifconfig |grep ppp0|awk '{print $1}'`

N=2

if [[ $inter != ppp0 ]]

then

/sbin/adsl-start

sleep 20

pkgloss=`ping -c4 $gateway|grep 'transm' |awk -F',' '{print $2}' |awk '{print $1}'`

if [[ $pkgloss -lt $N ]]

then

echo "`date +%Y-%m-%d/%T` The network is not stable">>/root/adsl.txt

else

echo "`date +%Y-%m-%d/%T` The network is normal">>/root/adsl.txt

fi

fi
