The term "virtual PBX," or "virtual phone system," means that the provider takes care of hosting the PBX itself and applying all the technologies necessary to provide communication services to companies. Calls, alerts, and other functions are processed on the PBX server located at the provider's facility. For these services, the provider issues a monthly bill that usually includes some […]
Today, the need arose to monitor changes in specific files on the server. There are many different ways to do this, such as osquery from Facebook, but since I recently started using Open Distro for Elasticsearch, I decided to monitor files with Elastic, using one of its beats. I won't go into the details of installing the Elastic stack and Auditbeat; it’s all in the manuals. The only thing is, after installation, edit the auditbeat.yml file to […]
In the previous part, a more or less functioning memory controller was implemented, more specifically, a wrapper over the IP Core from Quartus, serving as an adapter to TileLink. Today in the section "Porting RocketChip to an obscure Chinese board with Cyclone," you will see a working console. The process has dragged on a bit: I thought I would quickly run Linux and move on, but […]
In the picture, the Linux kernel sends you greetings via GPIO. In this part of the story about porting the RISC-V RocketChip to a Chinese board with Cyclone IV, we will manage to run Linux and learn how to configure the memory controller IP Core ourselves and slightly edit the device tree source description. This article is a continuation of the third part, but unlike the previously sprawling one, it […]
Hello! Any good story must come to an end. Our story about how we devised a solution for quickly bypassing the Chinese Firewall is no exception. So I’m eager to share with you the final part on this topic. In the previous part, we discussed numerous test setups we created and the results they yielded. We left off at the point of what could be improved […]
Metrics are nonsense, you might say, and you would be right. In some ways. Indeed, when it comes to metrics, the very first metric that comes to mind is traffic. Many love to meditate for hours watching the traffic graph of their website. How cool is it to observe the line bouncing back and forth, back and forth… And even cooler when the traffic of the site […]
Honestly, Ivan often laughed at the futile efforts of his colleagues in the monitoring department. They were making tremendous efforts to implement metrics requested by the company's management. They were so busy that they didn't want to do anything for anyone else. Meanwhile, the management was never satisfied – they constantly ordered more and more metrics, quickly stopping the use of what […]
A week has passed since Ivan first contemplated DevOps metrics and realized that they should help manage product delivery time (Time-To-Market). Even on weekends, he thought about the metrics: 'So what if I measure the time? What will it give me?' Indeed, what does knowing the time give? Suppose delivery takes 5 days. And […]
Today, in IT infrastructure, with the widespread use of virtualization, storage systems serve as the core, housing all virtual machines. A failure of this node can completely halt the operations of a data center. Although a significant portion of server hardware has fault tolerance in one form or another 'by default', due to the specific role of storage systems within the data center, increased demands are placed on their 'survivability'. […]
Scanning documents over the network seems to exist on one hand, but on the other, it hasn't become a common practice, unlike network printing. Administrators still install drivers, and the setup for remote scanning is individual for each scanner model. What technologies are currently available, and does such a scenario have a future? The installed driver or direct access […]
Greetings, esteemed Hub residents and casual visitors. This series of articles will discuss building a simple network for a firm that is not overly demanding on its IT infrastructure but nonetheless needs to provide its employees with quality Internet connectivity, access to shared files, and VPN access to their workplace and […]
SDSM has ended, but the uncontrollable desire to write remains. For many years, our brother suffered from mundane tasks, crossing his fingers before commits and losing sleep due to nightly rollbacks. But the dark times are coming to an end. With this article, I will begin a series about how I envision automation. Along the way, we will explore the stages of automation, variable storage, design formalization, RestAPI, […]
