shell实现自动adsl拨号

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/bashgateway=`ifconfig ppp0 |grep P-t-P| cut -f 3 -d ":"|cut -f 1 -d " "`inter=`ifconfig |grep ppp0|awk '{print $1}'`N=2if [[ $inter -eq ppp0 ]]then/sbin/adsl-stopsleep 10 /sbin/adsl-startsleep 20pkgloss=`ping -c4 $gateway|grep 'transm' |awk -F',' '{print $2}' |awk '{print $1}'`if [[ $pkgloss -lt $N ]]thenecho "`date +%Y-%m-%d/%T` The network is not stable">>/root/adsl.txtelseecho "`date +%Y-%m-%d/%T` The network is normal">>/root/adsl.txtfifi

脚本2:cat /root/soft_shell/auto_adsl_2.sh

#!/bin/bashgateway=`ifconfig ppp0 |grep P-t-P| cut -f 3 -d ":"|cut -f 1 -d " "`inter=`ifconfig |grep ppp0|awk '{print $1}'`N=2if [[ $inter != ppp0 ]]then/sbin/adsl-startsleep 20pkgloss=`ping -c4 $gateway|grep 'transm' |awk -F',' '{print $2}' |awk '{print $1}'`if [[ $pkgloss -lt $N ]]thenecho "`date +%Y-%m-%d/%T` The network is not stable">>/root/adsl.txtelseecho "`date +%Y-%m-%d/%T` The network is normal">>/root/adsl.txtfifi

ps:脚本2的作用就是检测adsl拨号是否有连上.
