Tunnel packets get filtered or stripped off, also certain packets like BGP

I was trying to figure this out for quite some while now. So I am trying my luck here now...

I have some VMs that should communicate with non VMs. There are 2 use cases.

The first are BareMetal Machines on the subnet that the external router is sitting on. The second are machines outside and behind the gateway pointed to by the external router.

So we have these two connection paths:

Kubernetes managing many distinct UDP servers on GKE
au flag

I'm trying to set up a system that can automatically spin up and down video game servers as docker images. In this case, factoriotools/factorio-docker. Each game is a different, distinct single-pod deployment of that container, and therefore (in the simplified case) needs its own IP address that can listen on a specific UDP port. Load balancers are redundant and irrelevant, and Cloud NAT doesn't ap ...

Connection Two sites

My office is moving and the big concern is about networking. The move will take two months but they need both sides to be operational during that time. The big challenge is our old PBX. Do they need phone connectivity in both offices for these couple of months? If we get a temporary internet provider for the new site can we connect the two modems with a VPN? Will that connection make the PBX work in the ...

self signed certificate vs a certificat authority with email
bo flag

I use a self signed certificate with my mail server. I use dovecot and postfix startTLS. I also have a DKIM setup for digital signatures and everything is working. However, when sending mail to hotmail or outlook it often if not always falls into the client spam unless they request to trust.

I wouldn't make any difference if I would pay to have a signed certificate authority would it? I mean  ...

Can't SSH into macOS machine until I VNC
sz flag

I have several M1 Mac Minis running on MacStadium. They are all remotely manageable, so I can SSH and VNC into them with the auth I was given.

From time to time, the following happens:

  1. I suddenly notice I cannot SSH into a machine anymore, but I have services running on it, so I know it is up and running.
  2. I VNC into the machine, and I’m greeted with the macOS screen requesting my password.

ls command that shows AM/PM

I'm using a CentOS 7 OS, configured based on AM/PM. Is there a linux command line (like ls --full-time) that shows full time information including AM/PM?

Below example does not show AM/PM:

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.
