RTMP/HLS Streaming Server operating on NGINX with Video.JS to provide live stream with mixed results
pg flag

I work for a small government entity that wants to provide live streams of board meetings for the public. We use OBS to do our encoding and it has never given us any problems, but lately we have had a lot of complaints that our live stream loses connection or simply never loads on our web end.

We are using an NGINX RTMP/HLS streaming server that was built over 5 years ago to provide this stream,  ...

How to hide that Nginx is a reverse proxy?
ro flag

Running the command nmap -A -sS mysite.com, it was demonstrated that the server is Nginx and that it is used as a proxy. Is it possible to hide this information?

Command output: 80/tcp open http nginx (reverse proxy)

I am using Nginx 1.18.0. In my nginx.conf, I set the settings (Some non-security settings have been hidden. The "..." means that.):

Is ApacheDS or Oracle DS impacted by Log4j CVE-2021-44228 - vulnerability?
pl flag

It's not obvious to me if these two products, which seem to use log4j (at least apacheds does), are impacted by this vulnerability. And if so, I'm not sure how to update to 2.16.0, as Apacheds is bundled in a wrapper.

Let me add, this is on Windows.

Any thoughts on this? Thanks Jeremy

I have a Windows Server 2012 R2 machine. What is the best way to search for log4j. Is it enough with a simple file search or can these files be used from inside a container. I have done a file search like this in power shell

Obtain real Ip from NGINX which is receiving from external L4 load balancer
kr flag

When a client use our services, network first go through L4 load balancer of our cloud provider(I don't have much control over this other than customer support).

In our server, traffic first hit the NGINX layer (dockerized) then passing to the backend services.

Nginx is receiving the load balancer's IP. "X-Forwarded-For" also null in the requests.

How can I obtain the real client IP from Nginx side?

Adding custom logging field to IIS with Add-WebConfigurationProperty does not work

I'm really struggling with this. The command is similar to what is confirmed here, and on numerous other sites.

Does Microsoft's Bicep DSL allow line continuation in function calls?

I'm starting to use Bicep to deploy Azure resources, and sometimes have to refer to other resources with the resourceId() function, but the arguments for this can be pretty long. In many languages, I could just put each parameter on its own line:

  'my-vnet',

VSCode's Bicep linter marks this as an error, however, while it is ...

Hyper-V (2016) has VM's running I cannot see - how to discover if more?
in flag

We did something silly, and "the client insisted" and "we got bad advice" is no excuse, but I could use help cleaning up. Background:

We added a new 2019 Hyper-V server to a group of four existing 2016 servers that replicate all around the network (no clusters or shared storage involved). The (bad) plan was that so long as we created the VM's on 2016, and did not upgrade from their configuration ...

I have deployed my Reactjs frontend project in an EC2 instance. Instead of users from the external internet world visiting my EC2 instance directly, I want to put it behind the AWS API Gateway. So AWS API Gateway would be the single entry point to my app's frontend and backend services. This is the plan to go with:

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.
