HaProxy accept-proxy + send-proxy does really connect
br flag

My current implementation is as follow:

  1. In front, an AWS Load Balancer (Network TCP/UDP type) on dual-stack, that redirects to a fleet of EC2 instances
  2. These EC2 instances are running HaProxy to receive the requests to a list of processes
  3. The list of processes are aiosmtpd instances (from Python).

Since the purpose is to connect via SMTP, I need to know the Client's IP, but I also need to send the  ...

Website using wrong URL after proxing though Nginx
cn flag

This is my first time using nginx and I'm finding this situation quite puzzling. My website is hosted at web.example.com and in order to reach the backend, requests are routed though nginx as a reverse proxy. After processing through nginx, the URL changes to the URL of the nginx server (proxy.example.com) instead of being the URL of the website.

The flow looks something like this:

Local windows clients can't reach Azure IaaS Domain Controller
kr flag

At work, we wanted to migrate our domain controller to an azure VM.

Azure AD and Azure AD DS doesn't fulfill our needs. Like GPO etc..

Well, let's say : I had 3 windows clients : CL1 (win10), CL2(win10), CL3(win7) and my domain controllers are : OnPremDC - ip : 192.168.0.10 || AzureDC - ip : 10.1.0.5

What I did first was to join CL1,CL2,CL3 to OnPremDC, so I changed the DNS settings manually of each cl ...

Allow files to be listed when viewing a directory but protected (via HTTP authentication) when accessed directly

I created a password protected directory using .htaccess and .htpasswd, but the files don't show up when I go to the directory URL.

Selective forward proxy for testing
ch flag

I have a very specific testing situation where I want to use a forward proxy like so:

Client -> Forward Proxy 1 -> Forward Proxy 2 (WireMock)
                         |
                          -> Internet

Forward Proxy 1 would be responsible for forwarding requests for a whitelist of (destination) hosts to Forward Proxy 2 (WireMock), which may send back a mock response or may proxy further  ...

How to query UCS network fabric information inside the OS?
br flag

On the Cisco UCS www page for the given POD, I can see what Fabric is used for a given vNIC.

But how can I query inside, from the OS (ex.: SLES12 or Windows server) what ethX (NIC) if from/via which network Fabric? ("A" or "B")

Or there is no tool that I can run inside the ex.: SLES OS to query these kinds of infos?

The no-load-balancer alternative
cn flag
X99

I'm working on a project where clients exchange data with services. We designed a proxy between the service and the client that anonymizes the user's data so anyone breaching into the database would only get a massive amount of useless data.

Of course, our proxy layer needs to scale, so we put it behind a load balancer using k8s.

The problem is: the Load Balancer is currently the SPOF (single point  ...

Azure Graph - Graph query to retrieve App Service Plan (Microsoft.Web/serverfarms) CPU%
br flag

I need to do some consolidation on my company's Azure estate, especially around App Service Plans.

In the past, we would typically create a new App Service Plan for each service we deployed as this would aid us with departmental cross-charging as each ASP would be tagged with each department's cost code.

We now have a massive sprawl of ASPs and I suspect none of them are probably running anywhere ne ...

squid commSetConnTimeout

I'm using squid 3.5.20 on centos. I send a curl request to bigquery directly without a squid proxy, and I have a response after 8 minutes.

Now, when I launch the same curl request through the squid proxy, I have a response after 15 minutes.

When I set debugging mode on squid, I can see a timeout of 900 during the tunnel.

Is there a real point to using "Run as" local admin accounts instead of logging in as a local administrator?
uz flag

Let's start by setting the scene -- I'm a junior systems administrator tasked with conducting a transition of the company towards a "Least-Privilege" model. This includes removing admin rights from our users, who mostly work with Windows 10.

Now at this point in time, users are (for the most part) using accounts with local admin rights. This is obviously pretty bad, and we're working on changing  ...

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.
