• 我以为网络设备跟linux服务器一样可以用ssh远程执行命令，但是发现我错了，

  • 第一版脚本如下

    #!/bin/bash
#20230130
#by lipeichao

cat list|while read line
do
ip=$(echo $line |awk '{print $1}')
user=$(echo $line |awk '{print $2}')
passwd=$(echo $line |awk '{print $3}')
fip=$(echo $line |awk '{print $4}')
system=$(echo $line |awk '{print $5}')
time=$(date "+%Y/%m/%d %H:%M:%S")
echo $time
if sshpass -p "$passwd" ssh $user@$ip "ping -q -i 0.1 -c 5 $fip" < /dev/null 
then
      echo "$ip $system $fip is ok"
else
      echo "$ip $system $fip is fail"
fi
done
  • 发现并不返回执行后的结果，还卡死了

  • 第二版脚本

    #!/bin/bash

cat /home/monitor/list |while read ip fip system
do
time=$(date "+Y/%m/%d %H:%M:%S")
echo  $time
  {
      /usr/bin/expect <<-EOF
      spawn ssh xunjian@$ip
      expect{
          "yes/no"{send "yes\n";exp_continue}
          "*password:"{send "$passwd"}
      }
      expect "*>"
      send "ping $fip\n"
      sleep 5
      send "quit\n"
      interact
      EOF
  }
echo \n
echo $system
done
