Removing specific characters from a string on ansible
lc flag

I have the following

- set_fact:
   test_result: " {{ htmlres.content | regex_search('http://website([0-9]+)', '\\1') }}"

Using debug, this returns the following " '[01]'"

Wanting only the number, I did some experimenting using the replace() function and was able to strip the [ ] by adding the following:

Check_mk agent listening on ipv6, how to change to ipv4
gb flag

Hi I am new to check_mk and not very good in linux server configuration at all, so thanks for your patience.

I installed check_mk under debian via gdebi (systemd not xinetd - and used default configuration so far) and also deployed several agents already. That worked good on most machines. but on machines, where ipv6 is deaktivated for security reasons, it does not work. (https://security.stackexchange ...

I'm monitoring my servers using Wazuh 4.1.x. My servers are Ubuntu and CentOS. They are also monitored using Icinga2 and NRPE agent. Wazuh is logging all sudo authentications or commands ran with sudo (which is fine). But since some of the nrpe commands need to be executed with sudo I would like to ignore all the sudo request from the nagios user. What I've tried so far is this:

Microsoft Outlook (on Android) will not connect to postfix (SMTP). In the Android app, you will get the message that an error has occurred. On the postfix side I see that an SSL error occurred:

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
