How to research what dominated my CPU for a few hours
cd flag

I have a little server (CentoOS 7 running on Linode) that is normally very quiet. But while I was asleep last night it went nuts for about 6.5 hours running something. By the time I got a chance to research it, it had gone back to normal. Here is what Linode's analytics graphs show for the last 24 hours:

The CPU is what tripped alarm bells and alerted me, but see also the Network IPv4 - there was a ...

Connecting GCP VM instance to Google Domain
bf flag

I am trying to connect a domain name I got from Google Domains to a Google Cloud Platform VM instance. My domain is .dev and when I tried nslookup and dig trace, they are already pointing to the right IP address. Accessing the website using this IP works fine. I just cannot access the same website via the domain name.

The following is the configuration I did:

In my VM instance (Compute Engine API):

Clean install of Kubernetes on Raspberry Pi doesn't work
cn flag

I'm trying to do a clean install of Kubernetes 1.23.x on a cluster of four Raspberry Pis, each running the x64 version of Raspberry Pi OS, however I am running into a major snag as soon as I try and run kubeadm init on the master node (before even attempting to get the other nodes to join). Namely: just five minutes after calling kubeadm init on the master node, the cluster stops working. In fact, ...

prevent ssh connection being lost after connecting to vpn server on Azure ubuntu 20.04 vm
us flag

I've created an Ubuntu 20.04 scale set (2 vms) on Azure and access these vms via ssh from my laptop's shell.

I want one of them to be connected to nordvpn (using nordvpn connect command, default is openvpn connection protocol).

Once the vm connects to nordvpn server the ssh session hangs and no new ssh session can be established, so only hard reset of the vm helps to reconnect to it.

Is it possible to use https with a Tang Network Bound Disk Encryption server?
ca flag

Is it possible to use https with a Tang Network Bound Disk Encryption (NBDE) server?

Redhat's documentation casually says this is possible, but I can't find any examples of this anywhere and the source code leaves me to believe otherwise.

SonicWall VPN Won't Connect
us flag

We use the SonicWall Global VPN Client as well as the built-in windows VPN to create VPN connections. As some of you know, update KB5009543 prevented us from creating VPN connections. Some of the computers I was able to uninstall the update and get the VPN working again. But I have about 5 computers that I cannot uninstall the update. The update history shows that the update was installed, but when I cl ...

PDCe time won't sync
jo flag

I'm encountering a very strange situation where the time on my VM-hosted PDCe is reported as synced, but the actual time doesn't sync. The server's running about an hour fast.

Here's what I've got:

enter image description here

I'm unable to update the time at the command line:

Here's the time service configuration:

I had the time sync set in GPO, as illustrated here, but I've turned it off for the duration of this exercise. Od ...

Good afternoon,

Our main DC out of the blue started restarting ending to BSOD with the error of "system thread exception not handled" caused by http.sys

I have already tried a clean boot, a BIOS update, a replacement of HTTP.sys from the file retracted from the same server's yesterday's backup, disabled the IIS service from safe mode, runned sfc and dism without any luck in restoring the server. I a ...

Postfix - Prevent multiple RCPT from exchange server
in flag

For a particular requirement to just collect incoming emails, I use milter to write and not queue further. Though the same postfix handles two domains, however I need to allow only one RCPT per email (it can have multiple To: not an issue). Found that ms-exchange (sender) at times combines multiple RCPTs in the same email submission to postfix, when it had to send two same emails to both the domains t ...

What is the proper way for multiple IP blocks to point consistently to the same internal IPs?
jp flag

If we have 2 IP blocks from different ISPs coming in and we want to accept traffic on either, how can we map IPs internally (NAT/VIPs) without duplicating for each external IP block?

We are on FortiGate 100Es with FortiOS 6.0.14

For example with ranges 1.2.3.1/27 and 6.5.4.46/27

Currently if we might have:

  • 1.2.3.12 to 192.168.2.56
  • 1.2.3.24 to 192.168.2.28

we would want the other block also mapped ...

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.
