istio gateway Not launching internal links, how to fix that?
ke flag

I have deployed application in kubernetes. It is working if we expose to a default load balancer service in azure kubernetes. But, after setting a virtual service linked with istio ingress gateway, it is launching only the home page, none of the links are working like /admin /login.

I have added entries for /admin and /login already in virtual service but it is not opening those pages.

NGINX / Cloudflare random 520 HTTP errors when HTTP2 is enabled within NGINX
us flag

I'm seeing a problem where Cloudflare returns a 520 HTTP error code to roughly 10% of requests. However the issue does not occur if I bypass the Cloudflare proxy, and request from the server directly.

After lots of troubleshooting, I've discovered if I remove the two http2 parameters after listen, then the issue goes away, and Cloudflare stops returning the 520 errors.

Established connection to StrongSwan VPN running on Ubuntu but can't connect to the internet

I have an issue connecting to the internet though I have established connection to IKEv2 VPN running on an Ubuntu VM on GCP. I have connected to the VPN from my Macbook. I followed this tutorial to install the VPN on an Ubuntu VM. The only difference from the tutorial is that I changed the domain names in the tutorial to an IP address of the GCP VM.

Here is the /etc/ipsec.conf configuration:

Print Management Console - All printers, drivers, ports missing
br flag

When running the Print Management console, nothing shows up in the drivers, ports, or printers. I can add new printers via the wizard. Then browsing to the UNC of the server I can see them. But the Print Management console shows nothing. Additionally, trying to connect to one of the printers ends up stuck on "Downloading the driver..." for at least 15 minutes. I gave up after that. Not sure if those are ...

Configuring a cloud VM to be accessed by multiple users
sg flag

I am a college CS professor. I want to have a remote server that all of my students can connect to. This is incredibly easy to do when I own the hardware. Just create user accounts on my server with the permissions I want them to have (read/write access to files in one folder, database connection), give the students the credentials. Easy. So easy.

This seems impossible to do on any of the major c ...

Saving the date to actual bash history file
mx flag

When adding "HISTTIMEFORMAT" to bashrc, the timestamps of when a command was executed are made available when running the "history" command.

But the timestamps themselves are not saved to the bash_history file (atleast not in plain text).

I am looking for a solution that will write the timestamp to the file itself so that archived .bash_history files from various workstations can be viewed in an edi ...

How to setup a failover server with KVM and DRBD
ru flag

I have a server that I am virtualizing using the Virtualizor control panel. I need to set up a failover server that syncs everything on the first server to the second server. I am using DRBD to sync the servers. I have a couple of questions as I am new to this.

When using DRBD my understanding is that DRBD syncs partitions. In order to set this up should I sync just the KVMs or do I sync the part ...

Google cloud: CDN (https) gives static up to 20 seconds

I am using Google cloud.

In the logs of the load balancer, it can be seen that the CDN (https) gives static from 2 to 20 seconds. This happens often, provided that a couple of people use the site.

Also, the problem is not only with him, but also with Cloud Run. Sometimes it gives the static for 2 seconds. It is difficult, but really to try to find an explanation. But in the  ...

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.
