Accessing the server using the router's IP works inside the network, but not outside
in flag

So I have a domain (nextcloud.selfhosted.tamashalasi.com) which points to 91.101.56.134: A Record which connects the domain to the IP

The public IP of my router is the mentioned IP, this screenshot is from https://whatismyipaddress.com/ My IP address

...and this is from the router's page (note that although it is a dynamic IP address, the IP address only changes if the MAC address of the router changes): enter image description here

I have a server on the network which has the name  ...

virt-manager's remote-viewer: fails to connect thru SSH tunnel with "incomplete link header (-104/16)
ne flag

I have a server running libvirtd with QEMU/KVM domains. I would like to access it with virt-manager from a remote machine, for which I open an SSH tunnel and forward a TCP port (libvirtd is listening on a local TCP port). Then, virt-manager is able to connect to the local socket with virt-manager -c qemu+tcp://host:port/system.

Unfortunately, virt-manager is not using its own connection for tunneling  ...

Why apache2 is using so much CPU power from a EC2 instance?
cn flag

This is my case: i have a ec2 instance with 5 virtual hosts running apache2. Sometimes, randomly, the CPU goes over 80% utilization because of apache. The sites are not so elaborated, and not even get so much traffic, thet're informative.

We thought it was a DoS attack, or a dictionary attack (for SSH). The instance has fail2ban and strong parameters in sshd.conf.

Is there any way to track exactly what ...

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.
