检查linux网络状态的两个脚本

一、通过定时收发email检测网络连通性

#/bin/bash
echo "daily test mail" > state.txt
mail -s server_state [e-mail] < state.txt
rm -df ./state.txt

~                        
crontab -e
增加如下任务
10 07 * * * /root/checknkmail &
分时日月周

二、定时检测网络状态通过email发送

checkserverstat脚本内容：

#/bin/bash
echo "hztelecomdns" > state.txt
ping -c 5 202.101.172.35 >> state.txt
echo "
bju" >> state.txt
ping -c 5 10.x.x.x >> state.txt
echo "adsl gateway" >>state.txt
ping -c 5 x.x.x.x >> state.txt
echo "server_outside vpn" >>state.txt
ping -c 5 192.168.2.100 >>state.txt
echo "server_outside wan" >> state.txt
ping -c 5 x.x.x.x >> state.txt
echo "vpn in company" >> state.txt
ping -c 5 192.168.1.4 >>state.txt
echo "l2tp at aaa libweb" >>state.txt
ping -c 5 x.x.x.x & >>state.txt
mail -s server_state [e-mail] <state.txt
rm -df ./state.txt

crontab中增加任务

corntab -e
10 16 * * * /root/checkweatherstate &
10 09 * * * /root/checkserverstate &
10 13 * * * /root/checkserverstate &
