Openvas OMP 的 Bash 脚本答案

【问题标题】：Bash Script for Openvas OMPOpenvas OMP 的 Bash 脚本
【发布时间】：2014-05-13 18:30:53
【问题描述】：

我正在编写一个脚本，试图让 OpenVAS OMP 完全自动化。该脚本应该能够询问什么类型的扫描，ip，名称，评论，输出类型。它遍历所有菜单，然后显示以下内容：

Failed to read response.
Starting Scan
Failed to start task.
Failed to read response.
get-report requires one argument.

我有它 echo 开始扫描，但其余的我不确定它们是如何出现的以及为什么。当我在脚本之外运行每个命令时，它们确实有效，所以我猜测它与读取变量的方式有关。代码如下，非常感谢任何帮助。

#!/bin/sh

mkdir openvastmp 
cd openvastmp

【问题讨论】：

当您使用-xml 标志时，您将shell 变量放在单引号内，shell 不会将其扩展为实际值，但将被视为文字。如果你用双引号替换这些会发生什么？
xml标签后或变量周围的单引号？
两者都有！我也很好奇哪个omp 命令给出了Failed to read response. 错误
我会试一试，我现在有一些会议，但一旦我回到实际工作中我会通知你的。我会让你知道是什么导致了这些错误。
所以我实际上知道 Failed to read 响应错误是什么。它们实际上是当系统将数据传输到文件时，因为它看不到响应代码。

【解决方案1】：

当你使用 XML 代码时，它不会将 $a、$b 理解为变量，而是将其理解为字符串 $a、$b。我的代码也遇到了同样的问题。如果您在 XML 代码之前传递变量，则不会有问题。
