Connecting To 127.0.0.1…Could not open connection to the host, on port 8123: Connect failed
jp flag

enter image description here

Well aware this has been asked, but I have scoured Google/StackOverflow and tried every single suggested solution, without being able to connect to port 8123 on my local (which is running Windows 10). It is worth noting that I CAN connect when I use port 8080. But I need 8123 to run a legacy application that has the port hardcoded in many (random) places...I have done the following:

Ignore chrony source with obviously wrong time
cn flag

I have a robot and am using timemaster to start chrony and add a PTP source from my GPS. When I start the robot inside where it can't get a satellite fix, the GPS claims it is January 5th, 1980. As a result, I get a stratum 0 source that is selected and the time is stepped to 1980 (because I have "makestep 1 3" configured for chrony) and then when I take the robot outside and the GPS starts advertising  ...

NGINX setup for REST API returning default configuration
cn flag

I've hired a VPS to play with some personal projects. To get started, I'm trying to set it up to host a REST API using Node.js, as I've only ever used Spring Boot for that.

I've implemented the solutions by adapting from the following guides:

https://www.robinwieruch.de/node-express-server-rest-api (most of the API code looks like this)

Automating cloudwatch agent installation for multiple arch types

I need to automate cloudwatch agent installation on new and existing instances created in EC2. We have a mix x86_64 and arm64 arch type vms as well different OSes(Ubuntu/Amazon Linux).

Which clients support self-signed certificates with DANE?
ru flag

We've been considering to make more use of DANE as a decentralised authority for our certificates.

Especially with S/MIME.

However, the key obstacle is... how widely are DANE treated as an authority with mail clients?

Is there a list with all the clients (mail, web, ftp, ssh and etc...) that support DANE?

Thanks,

Can LACP run over Linux tunnel devices?
in flag

I'm looking for a way to know if a tunnel device is up or down without needing to use ping myself. Every single tunnel device (gre, ipip, l2tp, geneve, etc) does not have a logical mechanism to decide if the tunnel is up or down, it is determined by the ip command. Maybe IPSec can do that (because you can look at the status of IPSec) but that's more work than I want to go to.

windows static routes location when created using netsh

On older windows systems persistent routes that were created with "route add" seems like this location is where they are stored in the registry.

When a persistent route on Win2016/Win10 is created using netsh is there a new location where the persistence happens? I tried to isolate it with procmon but didn't find ...

ETCD Cluster configuration for Kubernetes: Which one should be considered?

I would like to know how to deploy a ETCD cluster for Kubernetes. It seems like there are two different documentation and I don't know which one must be considered or the impact of each of them.

From the Kubernetes documentation for a multi-cluster etcd, it suggested to start it like this

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.
