In GCP load balancer monitoring, what is "unhealthy network traffic"?
ar flag

I'm running an Google CloudRun instance for an API. Today I've added a load balancer in front of it, so that I can set an SSL Policy that disallows TLS <1.2.

In the screenshot below, it appears that the traffic I'm getting from America is "unhealthy", and now warning icons are shown next to the different parts of my infrastructure. I'm pretty new to this area of GCP and I'm finding the docs im ...

AWS, nginx and LetsEncrypt

  1. Use nginx instance as a load balancer, attach an EBS to the instance, install certbot and store the certificates on the EBS. certbot will renew and update the certs on EBS. The web server in ...

How do I set up Fail2Ban on an Amazon Lightsail Debian instance, when it has its own firewall?
it flag

This is a very basic question, but all the answers I can find either relate to WordPress installs or Bitnami installs. I have a plain Debian instance running Nginx.

I would like to set up Fail2Ban. The problem is that Lightsail seems to have its own firewall, configurable via the console. It isn't clear to me how Fail2Ban would work with such a firewall, and I don't want to potentially screw up  ...

Showing message to the user during a Debian unattended preseeded installation
tr flag

During the late_command step of an unattended installation, I'm running a shell script :

d-i preseed/late_command string in-target /bin/sh -c './execute-script.sh'

When the late_command step is reached, the UI (blue background, grey window) displays a "Running preseed..." message :

enter image description here

I'm wondering if there is any way to lively displaying other messages based on what the execute-script.sh is doing.

Remote Desktop CAL - Why do I get 1000 licenses when I only bought 2 CALs?
vn flag

We bought 2 CALs from Microsoft and I installed them (probably) successfully (see screenshot below).

Screenshot Licensing Manager

Most things work as expected:

  1. I installed the 2 CALs as "per user" which shows up in the Licensing Manager
  2. For test purposes I connected with 5 different users --> 5 Licenses were issued

What I don't understand/ask myself:

SSH public key authentication with google authenticator still asks for password

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.
