NRPE: 用户脚本无法读取输入，但脚本正常工作，它可以是什么？

我写了一个脚本检查 Nagios, 这使其作为参数和检查方式：

如果设置了路径

如果可用，请触摸途中的文件。

如果挂载点目录是空的

[root@hadoop-nn1 mass1]# su - nagios

[nagios@hadoop-nn1 ~]$ /usr/lib64/nagios/plugins/check_nfsmount.sh /mass2/hpfiles/

Warning: /mass2/hpfiles/ is mounted but directory is empty!

[nagios@hadoop-nn1 ~]$ /usr/lib64/nagios/plugins/check_nfsmount.sh /mass1/hpfiles/

Warning: /mass1/hpfiles/ is MOUNTED properly but not writeable for user nagios

[nagios@hadoop-nn1 ~]$ /usr/lib64/nagios/plugins/check_nfsmount.sh /mass1/hp_offline/

Ok: /mass1/hp_offline/ is MOUNTED properly and writeable for user nagios

[nagios@hadoop-nn1 ~]$

B.

        /etc/nagios/nrpe.cfg

      

看起来像：

command[check_nfsmounts]=/usr/lib64/nagios/plugins/check_nfsmounts.sh $ARG1$

正如您可以看到的，当使用用户从跟踪计算机启动命令时 Nagios 结果是预期的，但是当我使用团队使用时

        nrpe

      

使用服务器 Nagios 他回来了 «NRPE: Unable to read input».

我尝试过的其他事情：

在脚本本身提供路径，因此无需通过 NRPE, 但同样的结果。

确保内部的路径

            nrpe.cfg

          

, 还要避免转移参数，但无济于事。

我编辑了

        nrpe.cfg

      

然后打开调试，然后在操作期间

        tail -f /var/log/messages |grep nrpe

      

并从服务器发送远程命令 Nagios, 我在期刊中看到这两条线：

Dec 15 04:09:44 hadoop-nn1 nrpe[9354]: Error: Request contained illegal metachars!

Dec 15 04:09:44 hadoop-nn1 nrpe[9354]: Client request was invalid, bailing out...

但我没有机会知道它是什么违法的象征 ...

对于参数 Don't_blame_nrpe 安装值 1. 脚本如下所示：

#!/bin/bash

# This script checks if the provided mount point is mounted and writeable.

# Script by Itai Ganot

if [ -z "$1" ]; then

                echo "Usage: $(basename $0) PATH_TO_CHECK"

                echo "Available PATH's: /mass1/hp_offline -- /mass1/hpfiles -- /mass2/hpfiles"

什么可能是出现错误的原因 «NRPE: 无法读取输入“？
