ph flag

I do the test with the special character password below

~`!@#$%^&*()-_+={}[]|\/:;"'<>,.?

And I realised nginx mail module encoded the % to %25, but the rest of the special character are fine, is it pre encoded from mail client level ?

Why is AWS Route 53 / Application Load balancer resolving a multilevel subdomain
ru flag

Within AWS I terminate TLS at an Application Load Balancer. I have configured a wildcard TLS certificate with AWS' Certificate Manager (ACM), e.g. *.example.com. I have AWS Route 53 resolving *.example.com, but I have nothing for *.*.example.com as I have no need for this.

I know you can't configure wildcard certificates for multi-level domains such as *.*.example.com.

TightVNC / VNC - execute commands inside VNC session from cronjob or just from outside shell?
cn flag

I have an application that cannot start without GUI, so I need some virtual display like VNC provides.

I boot VNC on start

What I want to do is run something each hour inside the VNC, without having to manually connect to it, and manually execute commands (what a nightmare).

Optimally from inside a cronjob.

I'm open to alternatives to VNC. Virtual desktop maybe?? I have never tried those, not sure what pr ...

SSH tunnel HTTP/S, client connections stuck in FIN_WAIT2 status
jp flag

I've set up a tunnel successfully between two servers, such that incoming connections on port 80/443 are forwarded to another server that is actually running the webserver. Further, I've used autossh to maintain the connection.

This works great, except that instead of closing fully, many of the incoming connections end up in a state of FIN_WAIT2:

How to use the output of a command inside ansible ini_file value
ve flag

I wanted to set a value inside a ini_file, but this value is an MD5 hash of the current time. (I am not afraid of accidentally replacing the value, or magically running it twice and having the same value in two different servers.)

This is what I tried, but got only the command as the value in the file (not sure why I thought it would work...):

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.
