How to find out DNS Server IP of other ISPs
sa flag

I am currently building a tool that needs the response from multiple different DNS Servers. The programming part is all done but I am currently lacking the IP Addresses of major ISP DNS Servers. All I can find are, what I assume, old ones that don't work anymore. When entering my local DNS Server or Public DNS Servers (Google, Cloudflare, etc.) I get the expected result. So my question is, is there a li ...

Kafka: monitoring length of queues / topics
in flag

We have several producers and several consumers connected via Kafka - basically, it's batch processing jobs that are created on demand, placed on Kafka in several queues, and the batch processors pick them up via Kafka and process them one by one.

I want to visualize and monitor the lengths of these queues in Kafka. The queue lengths will serve as proxies for the "load" of the overall system. The ...

I'm not familiar with any of this proxy stuff.

nginx config

I can't seem to find a solution to this issue. Right now when I type ex.domain.com it redirects to the IP address 192.168.1.202. How do I get it to visit that address but keep ex.domain.com.

I have port forwarding setup for nginx and if i remove "proxy_pass" it shows the nginx page with the domain url. which is what I want.

archlinux: kubernetes - coredns does not work properly
in flag

I have installed kubernetes v1.23.0 with Arch Linux as distribution. The cluster consists of a master and a node. Booth systems are KVM based VMs.

When a pod wants to make a DNS query, it gets a timeout when the service forwards the requests to a pod instance of coredns which is running on another kubernetes node.

So I suspect that the network provider is not working properly or some settings (ke ...

Can kerberos admin-server be on different machine than KDC?

I'm currently learning about Kerberos, and there's something I don't quite understand: Seemingly, the admin-server: kadmind - doesn't HAVE to run on the same machine as of the KDC. But that sounds weird - since kadmind does changes to the database by directly accessing the database file principal or principal.ok (Don't sure the exactly which does what but overall they're the ones that hold the databas ...

Which history file does the command in ssh client commandline go to?
id flag

If I do ssh user@server and then, inside the bash session, I run whatever, when ssh session is closed these executed commands go to .bash_history file. Simple and clear.

But if I do ssh user@server command, this command isn't logged anywhere. Beyond the reason (I suspect no bash session is spawned), what I want to know is: how can I log what commands have been executed in this manner, then?

How to assign a tty to a process?
fi flag

I can configure a command which will be run without a tty (similar to a cronjob). The problem is that the binary to be run seems to require a terminal. Is there a way to run a process with a new tty assigned? I don't really care about the output, but the binary seems to fail without it.

I tried to run it with tmux, but it seems like tmux fails if there is no terminal.

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.
