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.
