Can I listen to multiple domains in one ip on HTTP/3?

I'm using NGINX. I found that NGINX throws error when I set multiple domains for one HTTP/3 port.

Using active directory group as netgroup in sssd

I have an active directory domain with a handful of linux servers that interact with AD through sssd. I want to have a different sudoers configuration on different servers, and I know this can be done through netgroups. So far, I've managed to get some servers into a netgroup by adding a nisNetgroup object in AD, and adding servers to the nisNetgroupTriple attribute on that object (and setting the lda ...

How can I force a user to be logged off a specific time when they are using a RemoteApp?
mx flag

I have some RemoteApps that require all users to be logged out for a backup of the database to be able to be made. The issue is that sometimes a user will work very late and not log out.

When the person who's job it is to make the nightly backup goes into do that, they can not as those users are still flagged as active.

I have timeout policies in place for Idle Sessions via a GPO, but we have seen i ...

VirtualBox / OpenVPN - Can't ping between client and server, despite connect is present
uy flag

I have 2 VM's on my host machine. They are connected in "internal network", which is set in VM settings. I set up static IP addresses and ping works normally. I have OpenVPN server on one machine and client on another. I can establish a VPN connection between them but ping through tunnel doesn't work and client get disconnected after some time. Also, I've disabled tls-auth option to make it work.

How does Squid 4 compute a request's cache key?
cn flag

Sorry if I wasn't able to find the relevant doc on this: how does Squid 4 compute a given GET request's cache key? Is there a way to instruct to ignore HTTP headers in how it does this, i.e. only use the URL?

Long story short, I would need Squid to cache (and serve cached answers) purely based on the URL, and ignoring in particular Authorization headers (but still use that header if it needs to hit the  ...

Proper way to set congctl on systemd routes
jp flag

I'm using sysctl to set default tcp_congestion_control to bbr on all routes and I'd like to set the congctl to dctcp on the route added by a private interface. What is the proper way to do this? The only way I see is to add a script using ip command to replace the route but I'm unsure of stability of such setup when the interface flaps.

Safe to do firmware updates for multiple items at same time using SUU on Dell server?

I've run SUU on an older production server that I recently became responsible for (PowerEdge R730) and it has many different firmware updates listed. Is it save to just click the upgrade button or should they be done individually?

Strange issue with Pthreads - Why is there a delay in each new Thread Submit when opcache.enable_cli is disabled?

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.
