使用 bash ping 多个 IP？

使用 bash ping 多个 IP？

我有 10 个 IP 号码，每天必须 ping 一下以进行检查，如何使用 BASH 脚本来做到这一点。这样我就可以使用 cron 自动执行该任务。我只想要 BASH 脚本。

谢谢。

答案1

由于您的 IP 范围不对称，并且只有 10 个节点，我建议将它们列在文本文件中。我正在考虑包含列表的文件，其中list.txt包含每行一个 IP 列表，如下所示，

10.12.13.14
172.15.48.3
192.168.45.54
...
48.114.78.227

你可以使用这个脚本，

#!/bin/bash
# Program name: pingall.sh
date
cat /path/to/list.txt |  while read output
do
    ping -c 1 "$output" > /dev/null
    if [ $? -eq 0 ]; then
    echo "node $output is up" 
    else
    echo "node $output is down"
    fi
done

要以 30 分钟的间隔更新节点的运行状态，请使用 crontab，

*/30 * * * * /path/to/pingall.sh > /path/to/log.txt

log.txt 的输出

$ cat /path/to/log.txt
Fri Jan 31 15:06:01 IST 2014
node 10.12.13.14 is up
node 172.15.48.3 is up
node 192.168.45.54 is up
...
node 48.114.78.227 is down

答案2

检查这个脚本。

   #!/bin/bash
    for i in `seq ${2} ${3}`
    do
        ping -c 1 ${1}.${i} > /dev/null 2>&1
        if [ $? -eq 0 ]; then
            echo "${1}.${i} responded."
        else
            echo "${1}.${i} did not respond."
        fi
    done

例如，运行 ./script 192.168.1 0 10，这将检查 IP 地址 192.168.1.0 到 192.168.1.10，如果 ping 正常，则 echo 响应，否则，则不响应。

注意：如果范围和 IP 始终相同，则可以用静态变量替换 $1 $2 $3。

答案3

假设你有 5 个 IP（仅用于减少答案），那么你可以使用

#!/usr/bin/bash    
for i in xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx xxx.xxx.xxx.xxxx 
do
ping -c 5 $i
done

注意：IP 之间没有花括号，没有逗号（，）。

希望有所帮助。

就这么简单：使用parallel --gnu命令，然后使用你的命令。

获取示例 IP：

$ dig +trace google.com |ipx
