Why would DNS fail on the DNS server, but not on a host using the same DNS server?
in flag

I have set up Bind on a server running Centos Stream. The server has two interfaces, one to a corporate network and the other a private network. The DNS is set up for the private (192.168.0.0) network.

On the DNS server (192.168.0.2)

Mutual TLS on NGINX with 2 CAs?
jp flag

I'm curious, if I have a cert and private key issued by a well-known CA such as letsencrypt to establish a secure connection, but I'm using mutual TLS on NGINX, is it possible to have only the mutual tls auth reference a custom CA?

For example:

Connection is established and verified from Let's Encrypt CA. When client visits a path that requires a client cert to be present, I want that certificate to ...

We are looking at enabling the preconfigured WAF rules for added security measures and are wondering if anyone has implemented these rules or any manual rule to prevent DDOS attacks? What can be done manually within Cloud Armor to mitigate DDOS attacks outside of the Adaption Protection plan? Thanks in advance for any feedback.

How to get rid of secondary IP address without disabling dhcpcd (because there is no DHCP server anyway)
es flag

I have one system running RHEL7 that mysteriously keeps coming up with a secondary IP address in addition to the one I set statically. When I do "ip addr show eno0", it describes this secondary address as being "scope global secondary dynamic". There are no files in "/etc/sysconfig/network-scripts/" that call for a dynamic IP. And in the past, this has been good enough to get only static IP.

SSL certificate error when not typing FQDN and relying on default search domain
tr flag

DNS and SSL aren't really in my wheelhouse more than a rudimentary understanding, I hope what I want to do isn't impossible!

Here's the situation:

  • We have an internal domain and DNS servers, let's call it inside-company.com
  • We're migrating from self-signed certs and bought a wildcard DV cert for *.inside-company.com -- This is all internal-facing so DV is sufficient

OWA 500 error, ECP works fine

Tim

I'm getting a 500 error after logging in to OWA. I enter the credentials on the sign in form, it redirects to the frowny face with error 500. More details just shows my server name and the UTC date/time (I am -6 Central). However if I modify the URL from my.domain\owa to my.domain\ecp, I am immediately taken to the ECP. That seems to indicate that I am authenticating.

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.
