systemctl restart httpd Failed to start The Apache HTTP Server httpd pid already running

Forgive the cross post from Stack Overflow but I realized this was probably the better location to ask.

I recently rebuilt my server on AWS, upgrading from Amazon Linux to Amazon Linux 2, which like Linux 1 appears to be a fork of CentOS, now CentOS 7. My vhost config remains the same as the previous build while all the other conf files are the newer default files. (Just FYI, not sure it has any  ...

How to properly and completely remove a Windows domain controller?
jo flag

I have a single forest/domain with 2 DCs, SERVER2 and SERVER3. SERVER2 holds the FSMO roles. Both are healthy.

I now wish to remove SERVER2 for a clean reinstall. Based on my research for the project, I propose to take these steps:

  1. Transfer the FSMO roles to SERVER3
  2. Demote SERVER2 to a member server
  3. Remove SERVER2 from the domain
  4. Perform the reinstall of SERVER2
  5. Join SERVER2 to the domain

Construct public ipv6 adress from hostname of router and interface id of client
us flag
dba

I'm trying to ssh to some client behind a router that has a dynamic IPv6 address.

Directly using the public IPv6 address of the client works just fine.

Now, I'd like to dynamically construct the IPv6 address based on the hostname of the router and the IPv6 interface id of my client.

For example, let 2001:db8:: be my public prefix and the hostname's (example.com) ip be 2001:db8::1319:8a2e:0370:7347 ...

I have a publicly hosted zone in GCP for example.com. I want to move the hosted zone to AWS route 53. Is there a tool which can make this process easier?

Alternate: I will export the records using gcp cloud cli, modify the file to match the AWS route 53 specs, remove NS and SOA records and then import into Amazon route 53 using AWS cli tool

Does Postfix add the DKIM header before or after a message is queued?
eg flag

The Postfix configuration has been changed to add a DKIM header when sending a mail.

But Postfix is currently in the stop status, and mailq shows that new mails have been queuing in the meantime.

Will postfix start make Postfix add the DKIM header to these queued messages, or are these already processed and will be sent without the new DKIM header?

In github actions, we can set this using

Need to investigate why our server was DDOSing our host service provider

Hello everyone and hopefully somebody can give me a first step where I can begin investigating the reason to know why our Linux server appears to have attacked our service provider where the server is hosted on.

Today I received e-mail that one of our servers has been compromising one of our service provider customers as part of a coordinated DDoS botnet so they had to null-route it in order to m ...

IPv6 on ESXi with Hetzner

Haf

I'm having trouble with this one since I'm neither good at ESXi or networking so I'm mostly just following tutorials without being very sure about what I'm doing.

So I just followed this guide to use a separate VM as a router. Everything went fine up until the last step, since the "test" VM has no connection (the router one does).

This tutorial is supposed to work for an IPv6 subnet, as stated in the co ...

I've been following Kelsey Hightower's Kubernetes the Hard Way which walks you through manually setting up a k8s cluster.

This is not running on minikube - it's running on a remote VPS.

I'm on the step where I set up the k8s control plane.

However when trying to run a health check on kube-apiserver I get the following:

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.
