How to configure DHCPv6 in Proxmox without bridge?
tr flag

(crosspost: Network stack exchange)

I have a setup with Proxmox connected via WiFi. Everything works for my needs and IPv4 connectivity too.

Now, I want to see if it is possible to do some DHCPv6 setup so that my virtual machines have IPv6 addresses as well. I'd prefer a setup without NAT, but it's not mandatory that it is so.

I'm taking a few options into consideration for IPv6 connectivity:

curl --insecure not working

A L

I needed to run the below behind a proxy:

curl -L "https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh" | sudo bash

Which returned errors related to SSL (because the proxy puts its cert in between). I used '--insecure' and re-ran, which works up to a point, however - later in that install script, curl is called again, and returns the same SSL errors.

I added 'insecure' to ...

Make yum not installing dependancies if main package failed

I have 3 packages corepkg, corepkg-optB and corepkg-optC. corepkg-optC depends on corepkg-optB, corepkg-optB depends on corepkg. I've created a repo of these 3 packages. When I run yum install corepkg-optC, and corepkg failed, yum installs corepkg-optB and corepkg-optC. It is not what I would like.

How can I setup NAT with multiple public IPs (/29 subnet) on pfSense?
us flag

Our ISP provides a /29 subnet which includes the following IPs:

Network Address: 199.1.1.0
Router/Gateway Address: 199.1.1.1
Usable IP addresses: 199.1.1.2 - 199.1.1.6

I would like each of the 5 public IPs to have their own network (NAT), so for example the 199.1.1.4 public address could have the internal network 192.168.7.0, and public address 199.1.1.5 could have the internal network 192.168. ...

Logging user creation and deletion with auditd

What is the best way to log/detect user creation on linux machines by using auditd? I was thinking about logging calls to /usr/bin/ and /usr/sbin/ and filtering out useradd, adduser, deluser and userdel respectively. I also thought about using the /etc/passwd rule as for every user creation /etc/passwd is changed? Are there better ways? Are there ways to create and delete users which wouldn't be aud ...

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.
