in flag

I'm running a simple bare-metal multi-master "high availability" enviroment with 2 masters and 2 workers, as well as another VM with HAProxy serving as external Load Balancer.

My question is: it is possible to access the services (dashboard, ngnix, mysql (especially mysql), etc...) from outside of the cluster, exposing them to the network with this setup that i'm running?

I have a problem with our setup, we need ssl on all our domains and we have a domain which is hosted under subdomain.*.domain.com. And our SSL Certificate covers both *.domain.com & domain.com.

But when I import the certificate for subdomain.*.domain.com then the browser starts telling me that the website is insecure.

The certificate is working in when *.domain.com, so the certificate is working ...

How to tell Safari playing video that the video it is playing is not available anymore?
in flag

We're running some nginx servers hosting videos (in an educational institution). The files are stored as mp4s on disk and browsers either keep a TCP connection open and read video data as they need, or close the connection and send the next HTTP range request. The latter is preferably used when users seek in the video.

Range requests works fine as long as the video the browser is playing is still ava ...

Lots of suspicious GET requests that overload my CPU

I have a DigitalOcean droplet that hosts a small website with pretty much no traffic. Yesterday, I received an alert that my CPU was over 95%. Normally it runs between 1% to 5%. In the "bandwidth" chart on my DigitalOcean dashboard, the outbound traffic suddenly increased by a lot as seen in this screenshot :

Set automapping for exchange-online SharedMailbox as default for all user

We have some migrated sharedmailboxes on a exchange online mailserver. When users get access to one of these mailboxes via mailbox delegation setup, these mailboxes do not appear automatically in their outlook.

I know there is a powershell script for enabling automapping for a single user for a mailbox.

HAPROXY - redirect URL and keep the same URI
cn flag

Im using haproxy to do redirections. Basically I have a URL ( https://google.com// ) and I want to keep the same URI and just redirect only the base url ( https://test.com//). For HAPROXY it has to be irrelevant whatever comes after the base url will stay the same, only the base url needs to be changed.

Thankyou

Linux kernel firewall logging - how to change where it goes?
cn flag

I'm using an iptables based firewall, Firehol. It's great but it generates a lot of logs. These logs go (a) to /var/log/syslog and (b) get echoed onto the virtual terminal.

This makes it very hard to use the virtual terminal as whatever you type gets flooded with messages.

Is there a way to get these messages to go into - for ex. /var/log/firewall.log - and not to be echoed to the virtual terminal?

rsync over multiplexed SSH connection and multiple jumphosts
id flag

I need to rsync a file from remote hosts to my local machine over multiple jumphosts. I'd like to use shared SSH connections so that I don't have to submit 2FA multiple times at some jumphosts.

The idea is I create a master connection

ssh user@jumphost01

then other connections

ssh -J user@jumphost01,user@jumphost02 root@target01

Shared connections control files in ~/.ssh/ look as follows

Vagrant ssh config fault
mq flag

Good afternoon. There was a need to configure SSH access from an external network to a virtual machine in Vagrant (VirtualBox, CentOS/7). I made a mistake somewhere and lost the ability to connect to a virtual machine without taking a snapshot.

Is it possible to somehow restore access to the virtual machine, or do I need to completely re-create (an extremely undesirable event)?

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.
