normally fail2ban useses iptables to block traffic originating from the intruder's IP

However my server is behind a reverse proxy and from my server's point of view all traffic originates from the reverse proxy:

How to set multiple listener rules to load balancer in AWS?
dz flag

I have set multiple listeners and rules for an internet-facing ALB as below

enter image description here

The 80 port only redirect to 443. On 443, I set two kinds of different rules with different target groups.

If I access /* path on my domain, it can forward to targetgroup1. But when I access /static/* path it got a 503 error.

If I change the order between /* and /static/, I can access /static but the /* got a 503 error.

I tried restarting sshd, doing a systemctl reboot, and shutting down/restarting the server from my host's web panel, but I'm still unable to SSH into the server. I'v ...

Providing working-directory in AWS CLI ECS run-task command
cn flag

Is there any way of overriding the working-directory from the task-definition default when starting a task from the CLI? It seems like a fairly easy thing and a potentially important thing, but, if it is available, it looks like it's going to be very obscure, in that it's not advertised in the CLI documentation or UI.

I'd like to protect two servers against attackers who blindly probe for urls.

my idea is to block requests after a certain amount of 404 status codes.

I could do this with fail2ban.

However one of the servers is behind a reverse proxy that I do not control and that does not communicate the originating IP address (and it will need a very long time before the request of forwarding the originating IP ...

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.
