I have tried two times and it always fails. According to this little guy debian stopped packaging mysql-client as of buster. I tried to cope with it by installing MariaDB but I struggle to find a useful tutorial. Then I tried with this tutorial but I get the following error when installing the client:

What could be the reason that docker bridge networks are not able to communicate with the world after an upgrade from debian 8 to 10?
us flag

I know, this question is very specific. After a whole day, I gave up and installed a clean Debian 10. Because on a system that got upgraded from 8 to 10, it was impossible for me to find the reason, why a container connected to a custom bridged network, is no longer able to talk to the outside world. In other words:

On both servers:

docker network create test

On the migrated server:

let teachers reset passwords of students in Active Directory
in flag
tux

I am at a school that runs ActiveDirectory (Windows Server 2012 actually) and our teachers want to be able to reset students passwords, they won't use the ticket system in case a student forgets their password but will be angry on the IT-Administration (duh!)

So I just want to give them the option to reset students passwords (only students passwords!). How do I do this?

k3s - select ingress nodes with default traefik
ru flag

I have a k3s cluster with

  • 1 master + 2 nodes
  • default traefik as ingress

Traefik is running on the master node.

  • Is there a way to label nodes / change manifest so that traefik runs on the nodes instead of the master?
  • Is there a reason for default traefik to run on the master node?

losetup mounts disk image as one device. How to loopback the partitions seperately?
kn flag

I have a disk image with 2 partitions. When I do #losetup -f <file> only /dev/loop0 appears. How do I make /dev/loop0p0 and /dev/loop0p1 appear? Using #parted /dev/loop0 it does show the 2 partitions are present. I need the 2 partitions present as seperate devices to chroot into the main partition and set up grub on the esp partition.

Windows time service sync to external ntp servers only if they coincide

I recently had a problem which I've never seen occur before. One evening around 2030 one of the DC's changed its clock back an hour. This server syncs to two addresses in pool.ntp.org. Nobody was present when this occured and the event logs clearly show time-service syncing against a public ip.

I can only assume that we hit a server which was incorrecly configured because, after the chaos the fol ...

Linking authentication FreeIPA and SSO
be flag

Long story short, my goal is to have all user permissions managed in one place and then deployed everywhere. My thoughts are that Active Directory/FreeIPA is perfect for this sort of thing. It also comes in handy because some users will need to login to linux servers. Also I need to link the account with a GSuite account (this is easy enough with the Google Cloud Directory Connector). The catch is that  ...

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.
