Allow IPs overriding deny rule
gl flag

If one blocks IPs using a deny rule, e.g.

deny 123.124.2.0/24;

Is it possible to then allow certain IPs in that range/CIDR block?

I would like to block all AWS (Amazon) IPs, but there are a small number of IPs I need to allow from the AWS ranges.

Upgrading from very old firmware on HPE ProLiant DL380e Gen8 Server - can I upgrade it to the newest version right away?
cn flag

I'm trying to upgrade firmware on a HPE ProLiant DL380e Gen8 Server. The current version is 1.22 Apr 19 2013, while the newest version available on HP's website is 2.80 (April 8 2022). Is it safe to upgrade it straight to the newest version or should I do it incrementally?

Windows Server 2012/16/19 upgrade
cn flag

I am running tests for the work related to upgrading the operating system while maintaining business apps intact. I'm facing troubles while doing the upgrade from Windows Server 2016 Evaluation Standard to Windows Server 2019 Evaluation Standard. I can do a clean upgrade, wiping out the personal files and apps, but I need to keep those files and apps.

However, I can't choose the second option. On ...

Blazor site on IIS - very bad performance with simultaneous users

The site was deployed on VPS (2 cores, 4 GB, SSD, Windows Server 2016). I have several clients and the traffic is not big - Google Analytics shows up to max several users simultaneously. Recently traffic suddenly increased to around 100  ...

.htaccess deny access to subdirectories from a certain domain
th flag

I have a server with a security flaw:

There's the main site https://example.com (on server /var/www folder) Then there's an additional app (on server /var/www/app/public) that is configured to be on https://app.example.com.

So the app is also reachable via https://example.com/app/public (i'd like to change that)

I have also the problem that the whole app is saved on the server for the developer. M ...

  • RS Server is implemented on Database Server

My server has been physically moved to a new rack with a new IP address, and now I'm getting OCSP errors? Could it be an IPv6 thing maybe?
ml flag

I'm pretty sure SSL certificates are almost always tied to a domain name rather than an IP address. And the vast majority of my traffic is unaffected, generally things are working well.

However, my php error log is now full of a lot of this (getting a few per hour):

How can I restore a Windows Server 2012 r2 Backup to a new installation of Windows Server 2012 r2?

My main server drive crashed, but lucky I had an image backup of the server on an external drive. So I tried re-installed Windows Server 2012 r2. I tried to use the installation media to restore the backup but it does not come up.

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.
