Arch Linux, incoming remote connections get dropped
cn flag

I'm running into an issue on my (up to date) Arch Linux server. I've been able to reproduce it with netcat.

If I start listening on my server with:

ncat -l -p 2000 -k

and then

telnet (my local ip) 2000

from a local machine, I'm able to see the connection working both ways.

However, if I telnet from a remote machine, the connection is established but nothing I type on the server side appears on t ...

It has an IPSec VPN connection to AWS VPC.

  • All hosts in the LAN can traverse the IPSec VPN successfully. Traffic flows back & forth fine.

Remove hashmark (#) from nginx url and redirect
in flag

I want to take a url, add a prefix as well as remove the hashmark from the url. For example, redirect from http://localhost:8088/app1/#/hello to http://localhost:8088/apps/app1/hello.

I've tried this but it doesn't seem to work:

  location /app1/ {
    rewrite ^([^#]*)([#])\/(.*) /apps$1$3 permanent;

It seems to have something to do with the hashmark. As I can go from http://localhost:8088/app1/q/h ...

Require authentication from subset of mynetworks in postfix

Is it possible to configure smtp for postfix to require authentication, (e.g. with smtp_sasl_auth_enable = yes), for certain IP ranges but have other ranges un-authenticated?

For our local network we want hosts to be able to relay through the smtp servers without authentication, including sending externally. That network range is listed in mynetworks.

But for other ranges, not on our network but in

How to force users to change their Windows Hello Pin
in flag

We changed our password policy in the Microsoft Endpoint Manager and now require a longer PIN.

The issue is, in testing we noticed you're only asked to change the Windows Hello PIN, when logging in with it. Since many of our users use biometric logins, they aren't asked to change it.

I'm looking for a solution where the user is asked to change the PIN regardless of the sign-in method. Just like when ...

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.
