How to block IP range with nginx
ru flag

In my server, I use nginx as web server. This server receives many visits from bad bots.

I know how to block specific ip, editing /etc/nginx/nginx.conf file and within the server block, add this line (example): deny 74.208.136.135;

But I want to block all access from 74.208.***.***

Is this possible with nginx?

Unplugged a working UPS by mistake. UPS made a bang noise and never turned on again
cn flag

I unplugged my running UPS by mistake. The UPS was new so the batteries were fine, also the load was very low. Could it be that the breaking of the ground path lead to the destruction of the UPS? Now it won't turn on and all the fuses I can access externally are not triggered

The UPS is the Eaton Ellipse Eco 1200

Is Ubuntu MAAS only for servers?
us flag

I'm trying to get my head around using Ubuntu MAAS as a means to deploy clients. All the documentation I see exclusively mentions servers. Can I use the MAAS platform to deploy a regular Ubuntu Desktop OS?

How is the age for public folder calendar, task and contacts determined?
jp flag

We are running Exchange 2016 on premise and the upper management wants to set an age limit for public folders. We have a lot of public folders with tasks, contacts and calendar items. How is the age limit (retention age) determined for these types of public folder items? There is a lot of information on how retention age is calculated for mailboxes but not for public folders.

Refreshing Windows DHCP Server reservation active/inactive state
in flag

I have a Windows DHCP server with a number of reservations. These all seem to work correctly (in that the addresses are correctly distributed) but, somehow, the Active/Inactive state of these has become corrupted in the Leases view on the DHCP MMC.

Machines that I know are not plugged in are showing up as Active, making it very difficult to see at-a-glance which machines are on-site or not (at le ...

merge attachments from two emails into one?

Is it possible to merge two emails sent to the same address within a couple of minutes into just one email? I'm dealing with some software that sends invoices in one email and a statement in another and I'd really just like them to be in one email. Can I do this with postfix? Or is there some other way of doing it? Like emailing it to a 'local' email address and then they get repackaged locally? Not sur ...

certbot option to _display_ configs (specifically currently-registered email address)

Does anyone know of an option with certbot (a.k.a. letsencrypt) to show the current configuration options? I know one can specify the config file (--config) and specify the registered email address (-m), but I'd like to inspect (in an automated way) the existing configuration values prior to executing a certbot command. I also know that I can inspect the canonical config file, but it's nice to have t ...

I hope you're doing great so; recently, I started using kemp as a load balancer for my server, and everything works fine when the service (real server) comes already with a self-signed SSL from the host, but when I try to add a new real server that its default is HTTP and doesn't have HTTPS when I try to access it the same way I do with the other the browser returns a 520 error.

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.
