Why Debian APT is not listing the same upgrades on two different servers with the same APT config?
in flag

I have two dedicated servers (virtual machines), located in the same datacenter, both running latest Debian Bullseye.

Today, I ran apt update on the first one, and it listed several packages to upgrade, related to PHP update from 7.4.21 to 7.4.25.

Then I ran the exact same command on the other server, which listed nothing. And I checked, PHP was still running the previous version 7.4.21.

How to increase speed of RAID 5 with mdadm + luks + lvm

I think I am kinda lost with my current server setup. It is an HP Proliant dl160 gen 6, and I put 4 spinning disks with a setup that has mdmadm + luks + lvm and on top of it btrfs (maybe I went too far?) and it is really suffering on IO speed it reads around 50MB/s and writes around 2MB/s and I have a feeling that I messed up something.

is it possible to intercept only nmap scannings with IPtables?
cn flag

I'm trying to redirect all scans coming from nmap to another destination. I'm trying IPTABLES, but I have no idea on how to tell apart the nmap scanning from the legitimate traffic.

Is it something achievable through IPTABLES or should I look somewhere else?

Bix

I recently ran a certbot command using --webroot on a server. Everything worked fine for 8+ hours.

This morning my frontend went down. Upon investigation I discovered that the apache2 service was down. It was masked for some reason so I unmasked it. It restarted but did not work. I tried to run a configtest but apache2ctl was not found. I ran sudo apt install apache2. Now everything is working ag ...

Microsoft ADCS: change Subject in existing CSR

Suppose I have a CSR in which some Subject fields were not created according to X.509 - there are forbidden characters in Subject, or Country was provided as "England".

Is there any way to recover from that?

  • editing request directly on CA, but since there's some forbidden stuff in the CSR, the req ...

How can I tell if wget can support LetsEncrypt's new ISRG Root X1 certificate after DST Root CA X3 Expiration

A few weeks ago (Sept 2021), LetsEncrypt changed how their certificates were signed, which can affect some older programmes and clients. I have a standard Apache webserver (stock v2.4.41 from ubuntu 20.04 apt) with several letsencrypt certs.

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.
