Every port in centos 7 requires elevated privileges

I'm trying to combine an express js app with nginx. The express app runs on port 3001 or 8000 and then with nginx I'd like to listen to port 443 and forward the requests to that app:

/etc/nginx/sites-available/example.com has this content:

Same Jenkinsfile works differently in two apparently equal servers
bd flag

I've been forced to change a jenkins server from one server to another twice. The first time, I moved it from an Ubuntu 20.04 server to an Ubuntu 21 without problems; the build (multibranch pipeline) worked fine.

But now I've been forced to change the jenkins again to another server that runs Debian 10 and now the pipeline skips all steps except checkout and post (sending an email).

This is the Jenk ...

Cannot fully disable gzip content encoding on specific POST requests
cn flag

I've been trying to figure this one out for a while.

I have disabled gzip/compression options on both Apache Tomcat (which is running the reportserver software in docker) and on nginx (acting as a reverse proxy).

Despite that, the server is still serving some gzipped content. There are 2 things that I noticed:

  • The gzipped content is always a json/xhr type
  • Not all requests are gzipped. The gzipped content ...

Is it possible to overlay local LDAP attributes on top of a replicated tree?

A central LDAP server provides user data as posixAccount, whereby the attributes homeDirectory and loginShell are empty. I want allow users in this central LDAP server to access a Linux system.

If I use syncrepl to replicate the data to a local LDAP server, I can use sssd to set the homeDirectory. I could also use sssd to set everyone's loginShell to, say, /usr/bin/bash.

It exists various storage device, file, block and object based. Some filesystem are dedicated to a kind of device. what about Btrfs ?

Here I would like to get some technical facts about Btrfs over a block storage device. Indeed, most of cloud provider documentation use another file system. Which lead to this legitimate question.

Moreover is their for Btrfs some interesting mount option to apply f ...

Only Allow 1 user to Remote Desktop at a time (Windows 2019)

By default Windows 2019 allows 2 users to remote desktop at one time. Is there a way to restrict this even further to allow only 1 remote desktop user at a time? I tried the following tutorial, however I'm still able to remote desktop with 2 different users at the same time. https://support.managed.com/kb/a1816/how-to-enable-disable-multiple-rdp-sessions-in-windows-2012-2012-r2-2016-and-2019.aspx ...

AWS S3 bucket policy for get and upload

I have two buckets each with their own goals. So far I cannot understand the complicated configuration of bucket settings. It seems there are three things to configure

  1. Block public access
  2. Bucket policy
  3. ACL

I know that if I turn off (1), that everything that I want to accomplish just works. Even though these are the four most meaningless settings I have ever seen (why would I care about restricting  ...

configure nginx to use a proxy when connecting to upstream

it's very hard to find something on google - you get too many results from nginx and proxy alone.

so we have a nginx-docker-container which delivers some static files and should talk to a backend-server on specific locations. we gave http_proxy and https_proxy per docker-compose into the environment of the container

trying the connection with curl results in success - its because of the http_proxy/h ...

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.
