Good day all.

The goal of the setup is to allow these internal VMs send passive checks to the Nagios Core Server on the public subnet of the same VCN.

Windows 10 blocking DNS queries on one interface when other interface returns Server Fault, in case of multiple active interfaces
ng flag

I have two active interfaces on my Windows 10 machine - Wi-Fi and Ethernet, each having their own set of DNS servers.

In ideal case I could see DNS request being sent on both the interfaces and response is also received from both the interfaces. But occasionally, the DNS on the Ethernet returns Server Fault in the response. In this case there is no DNS packet sent on the Wi-Fi. Is this the expect ...

Is AWS Fargate included in their "first year for free" plan?

I'm working for a cash-strapped not-yet-startup :D. We want to use Amazon for free to deploy a simple Python REST API endpoint. I was told that Amazon has a "1 year for free" tier. I've built my docker, put it on DockerHub and have successfully deployed it to Fargate.

However, I can't find the Fargate product here in their list of free stuff:

Isolating my docker container from the rest of my local network (route add reject not working)
jp flag

I'm just simply trying to add a route to reject any traffic to other systems on my local network from my docker container, but seems like my route add command isn't working and I'm not quite sure why.

The command I'm used to running is route add -net x.x.x.x/CIDR reject

enter image description here

I know I'm missing something very minor here in regards to the command, but cannot figure out what it is.

How to use modsecurity on AWS EC2 with ELB

Query attacks from outside are too frequent since AWS EC2 was used. AWS WAF is too expensive and burdensome. I'm trying to install modsecurity inside the server, but it's not working properly because of ELB. Is there any other alternative or way?

I have the following scenario: Two sites, each with their own network (non-overlapping private subnet), connected with a site-to-site VPN (layer 3, Wireguard). Routes to the other sites are configured in the default gateways and also distributed to the clients over DHCP. IP traffic (v4 and v6) travels fine between the networks.

Local DNS not resolving local hostname but DIG does

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.
