Wodle command test

[bah07]

We have detected some issues related to this module:

• When configuring more than one block of Wodle Command only works last one. e.g:

<wodle name="command">
  <disabled>no</disabled>
  <tag>test1</tag>
  <command>/bin/echo `date`:"First wodle command"</command>
  <interval>15s</interval>
  <ignore_output>no</ignore_output>
  <run_on_start>yes</run_on_start>
  <timeout>0</timeout>
</wodle>

<wodle name="command">
  <disabled>no</disabled>
  <tag>test2</tag>
  <command>/bin/echo `date`:"First wodle command"</command>
  <interval>1d</interval>
  <ignore_output>no</ignore_output>
  <run_on_start>yes</run_on_start>
  <timeout>0</timeout>
</wodle>

In log don't appear test1 tag:

2018/08/03 14:13:24 wazuh-modulesd: INFO: Process started.
2018/08/03 14:13:24 wazuh-modulesd:command: INFO: Module command:test2 started

• The second failure detected is related to the timeout parameter. It does not work if ignore_output is enabled. With next configuration:

<wodle name="command">
  <disabled>no</disabled>
  <tag>test1</tag>
  <command>/bin/bash /home/borja/testingwazuh/wodlecommand/noprint.sh</command>
  <interval>15s</interval>
  <ignore_output>no</ignore_output>
  <run_on_start>yes</run_on_start>
  <timeout>5</timeout>
</wodle>

Works fine and get next message error:

2018/08/03 14:22:47 wazuh-modulesd:command: INFO: Module command:test1 started
2018/08/03 14:22:53 wazuh-modulesd:command: ERROR: test1: Internal calling. Exiting...

But if change option ignore_output yo yes, the Internal calling. Exiting never appear.

NOTE: Change error message when killing process.
