I'm using EC2 with RHEL8.5 (Red Hat Enterprise Linux release 8.5 (Ootpa)). I wanted to install OpenLiteSpeed on that instance. my Question, Does OpenLiteSpeed support with RHEL8? If I don't wrong, centos and RHEL is on same umbrella, Red Hat. So why I cannot install OpenLiteSpeed using centos RPM in my RHEL 8.5?

Cannot password a channel using Unrealircd 5.2.4 and Anope 2.0
cn flag

I'm running ubuntu impish with unrealircd-5.2.4 and anope 2.0. I managed to setup things up and registered a channel using ChanServ, however the channel just can't seem to be locked, i.e. I can still join the channel without specifying a key.

This is the command I added, and I can see the key when viewing the channel's properties using mIRC

Allow docker containers on the bridge network to connect to the host using iptables
my flag

I have recently tried deploying iptables to only expose relevant ports. I'm dropping every incoming connection using iptables -P INPUT DROP and later on allowing access to relevant ports. This does work but breaks my haproxy setup with web servers running in docker containers. The containers now can't connect to the host network. I tried allowing the docker containers to connect to the host using

Can Google Virtual Private Cloud be used to give a GAS project access to resources inside a corporate network?
in flag

By default, a Google Apps Script project cannot access a resource (like an API or a DB using JDBC) inside a corporate network. The company would have to put holes in their firewall for the GAS servers to be able to connect to those internal resources.

But since all GAS projects run on the same Google servers, using the same APIs, putting holes in the firewall means that ANYONE, including GAS proj ...

How to hide origin IP of SMTP server by tunneling/proxying incoming port 25 traffic to real mail server
nl flag

We have most of our stuff behind Cloudflare.

However, some services such as mail (ex: mail.mydomain.com MX record) cannot be pushed through cloudflare and they expose our mail server's IP which makes it easy to discover where our infrastructure is located because they all share the same block and organization name (per ARIN whois).

Since our mail servers and VMs are at the same colo facility, knowin ...

Dynamic IP Address in VPN Setup

I have an infrastructure with two physical locations which we are connecting via a Site-to-Site VPN. Only one side has a static IP from the ISP whilst the other site does not as the ISP there does not offer static IP services. Long story short, we do not own the line at SiteB so cannot switch providers etc.

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.
