My Exchange Server 2013 writes "Error 15021" dozens of times in the Error log. It says, that there is an error using the SSL-Configuration. I googled the error but there seem to be a lot of hits concerning Port 443 but in my case it is Port 444.

How do I refer to the 'LXD host from an LXD container
mm flag

We currently run our services in a series of LXD containers - we have one running a nginx server as a reverse proxy, pointing at each service, and where I need to connect to a container from the host or another container, I use the LXD assigned hostname. It works very well, and its extremely clean.

Thanks.

What is a secure and user-friendly way to provide only a few users access to web app on Amazon EC2?
cn flag

Situation

We have a web app hosted on Amazon EC2. It's intended to be used only by a few users in a company.

How we're dealing with this

  • We share the (Elastic) IP address of the instance with the users.
  • We add each user's IP address to the security group of the instance as and when needed.

When I say as and when needed, I mean emails from the users complaining that the web portal is showing an error  ...

Getaddrinfo does not resolve in some kubernetes pod on some hosts
ma flag

I have a pod where getaddrinfo cannot resolve the address to a Kubernetes Service in the same namespace but can connect to the service if I use the IP address instead. Using tcpdump, I can confirm that it does not send DNS queries to nodelocaldns or to coredns. Manually adding the address to /etc/hosts does not resolve the issue.

Changing your kernel in AWS appears to break boot sequence (grub config issue?)

Using Ubuntu 20.04 on AWS (ec2), I wanted to change my kernel from AWS to a generic one. When I try it the suggested way with changing the Grub Config, it stops the machine.

This is because Jibri (Jitsi Video Recorder) requires the use of ALSA and to modprobe snd-aloop , but anything that would want a lowlatency or different kernel would have the same need.

What I tried:

/var/lib/mysql taking up large amount of space
cn flag

I have a very simple drupal project that I launched onto an AWS EC2 instance with 8GB of storage. However, something strange has happened and my EC2 ran out of storage. My mysql databases don't even take up 1/2 a GB, but my /var/lib/mysql folder has over 4GB allocated to it and I have zero idea why.

Where would I even start here to clean that up?

GKE autopilot, manual load balancer and firewall rules

I have this GKE autopilot cluster and I'm trying to setup a Load Balancer for it's services. The caveat is: Instead of defining an Ingress for the cluster, which would create the LB and all the related configs, I have to manually define an LB.

GKE creates all the NEGs I need and I'm just pointing existing cluster to them as backends, and it works fine.

The problem: I can't manually create a firewall ...

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.
