Apache "freezes" few times a day

JYD

I'm writing here after weeks spent fighting an issue that cause Apache to stop responding until it is restarted. It happens 3/4 times a day, sometimes after hours, sometimes after some minutes, sometimes after a day. There's non relation (at least there's no evidence) with the number of concurrent connection to the server: it happens both during heavy traffic period (between 8.00am - 18.00pm) and during ...

How to monitor Segate HDD health under Linux?
cn flag

I'd need to monitor the health of several Seagate ST16000NM002G SAS HDDs hosted in a disk server running CentOS 7. As far as I understand, Seagate disks do not expose S.M.A.R.T. attributes due to a precise management decision (see this page), and the company suggests to use their SeaTool software which according to them is more reliable than S.M.A.R.T. Sadly, it seems that only the SSD version of SeaTo ...

Is it possible to send mails via Postfix on another machine in the same LAN without having to relay it?
ve flag

I thought this was a quite common situation, but I'm struggling a bit getting this to work in the easiest way possible, and also, I'm not sure if I'm doing it in a good/recommended way by now.

I have two servers that can communicate via a LAN (and also, both have public internet IP addresses). One runs Postfix, the other one serves some websites.

What I want to do is to be able to send some mail (e. ...

CertUtil Windows Update gives me 430+ certificates?
us flag

There are several well known methods of downloading certificate lists from Microsoft, including certutil -generateSSTfromWU c:\my_cert\

Doing that (or just downloading authrootstl.cab) gives me a collection of more than 400 root certificates.

Now, I know that none of my connected servers have that many certificates loaded: and I just looked at a Win10 workstation and it has ~90 trusted root certific ...

KDC has no support for encryption type while authentication to OpenLDAP
fr flag

I'm running a Kerberos / LDAP authentication server for many years. Kerberos data is stored inside LDAP. Now, I have a second site and want to mirror the server to the new site. This basically works, but there is a strange side effect. Each server has a KDC and a LDAP running. KDC talks to LDAP using local ldapi:///.

If I use the original KDC krb1.example.com I can authenticate to the master LDAP and th ...

Get-IntuneManagedDevice fails to return devices with an implied "Default" scope tag
tr flag

We explicitly assign a scope tag to a group of devices. When looking at the properties of these devices they only show the assigned Scope Tag, not the implied "Default" scope tag.

This works fine in the UI, for myself with rights to all Scope Tags and for those with rights to just the "Default" Scope Tag.

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.
