shell实现自动adsl拨号并检测连接状况脚本分享
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:centos5.x
脚本1:
cat/root/soft_shell/auto_adsl_1.sh
#!/bin/bash
gateway=`ifconfigppp0|grepP-t-P|cut-f3-d":"|cut-f1-d""`
inter=`ifconfig|grepppp0|awk'{print$1}'`
N=2
if[[$inter-eqppp0]]
then
/sbin/adsl-stop
sleep10
/sbin/adsl-start
sleep20
pkgloss=`ping-c4$gateway|grep'transm'|awk-F',''{print$2}'|awk'{print$1}'`
if[[$pkgloss-lt$N]]
then
echo"`date+%Y-%m-%d/%T`Thenetworkisnotstable">>/root/adsl.txt
else
echo"`date+%Y-%m-%d/%T`Thenetworkisnormal">>/root/adsl.txt
fi
fi
脚本2:
cat/root/soft_shell/auto_adsl_2.sh
#!/bin/bash
gateway=`ifconfigppp0|grepP-t-P|cut-f3-d":"|cut-f1-d""`
inter=`ifconfig|grepppp0|awk'{print$1}'`
N=2
if[[$inter!=ppp0]]
then
/sbin/adsl-start
sleep20
pkgloss=`ping-c4$gateway|grep'transm'|awk-F',''{print$2}'|awk'{print$1}'`
if[[$pkgloss-lt$N]]
then
echo"`date+%Y-%m-%d/%T`Thenetworkisnotstable">>/root/adsl.txt
else
echo"`date+%Y-%m-%d/%T`Thenetworkisnormal">>/root/adsl.txt
fi
fi
ps:脚本2的作用就是检测adsl拨号是否有连上.
