Azure Arc - App Service Publc IP
cn flag

I have an Azure Arc enabled Kubernetes Cluster and was attempting to install the App Service preview extension but it keeps timing out. It mentions that the cluster has to have a public IP but not what ports are required... I tried forwarding Https but get the timeout still. Has anyone set this up? Or have a link to any more detailed instructions?

Nginx proxy_pass to server with different name/certificate
sn flag
a p

I've got a number of upstreams that I proxy requests to in an nginx reverse-proxy setup. Each of these has their own domain names and certificates to match. After turning on proxy_ssl_verify in my reverse proxy, I was expecting nginx to test that the CN in that certificate was valid for the server name in the upstream section. This is apparently not the case.

I'm now getting errors like this:

Remote port forward works on TCP/1194 but not on TCP/443 even though port 443 on the server is not being used
cn flag

I am having a weird issue.

I brought up a new Linode to act as a tunnelling endpoint.

I was able to successfully remote forward port 1194 so now connections to linode-server@1194 successfully to my machine's port 1194 and I am able to connect to my VPN by connecting to port 1194 on my linode-server.

The below command is what I used (the one that works):

Why is my Samba share only writable by root?

I have set up a Samba share, and it is only writable by root. For example, I can only create a folder on that share with sudo:

Is there anyway to use custom worker node OS or load specific kernel modules in standard worker node OS on GKE?
de flag

GKE appears to support 3 type of worker-node OSs as of writing this question (around mid Aug'2021) i.e. Container optimized OS, Ubuntu, Windows. So my questions are:

  • Is there a way (or a workaround) that lets one use RHEL as worker-node OS on GKE ?
  • Is there a way (or a workaround) to load a kernel module (s.a. modprobe sctp) into worker-node OS on GKE, say while working with Ubuntu as the worker-node OS  ...

NPS Event 6273 Reason 7 "The specified domain does not exist."
sz flag

Our AD domain is domain.pri and our UPN is user@domain.com. Normally this works fine.

We have a Win2008 NPS server for RADIUS WLC authentication that we want to replace with a 2019 box. Seemed straightforward until we went to implement.

Appears there is a "bug" in W2k8 NPS that we exploit to allow a user@domain.com to authenticate.

We've tried quite a few things including adding _ldap SRV records, etc  ...

When the server receives a request, does it automatically knows the website is itself?
it flag

My website URL is modified for access from remote systems like this:

//var url = "http://127.0.0.1:5000/dosomething"
var url = "http://www.somewebsite.com/dosomething"

The URL is used by the Python backend and JS front end. When the server receives a request, does it automatically know www.somewebsite.com is itself?

Why does my Ubuntu 16.04.6 LTS randomy reboot?
mx flag

I have a supermicro 1U running Ubuntu 16.04.6 LTS. The problem I am having is it reboots at what appears to be random intervals; it can go 2 days between reboots or it can go 2 weeks between reboots. It is a plain vanilla LAMP server with high frequency write requests to MySql. The average load to the machine is about 0.09, so it's certainly not under any heavy load. No crons are set up via crontab.

How to do port forwarding for GNS3 server (SSH tunneling)?

I have a GNS3 server, and I'm trying to add iptable rules so that when someone on my team connects on port 1100, they get routed to an internal IP such as 192.168.122.2:22. This internal IP belongs to a bastion host of a GNS3 project. The end goal is to be able to shh into the internal IP addresses from a local machine.

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.
