Creating a backup application that works on any distribution is quite a challenge. To ensure the Veeam Agent for Linux operates on distributions from Red Hat 6 and Debian 6 to OpenSUSE 15.1 and Ubuntu 19.04, a range of issues must be addressed, particularly considering the kernel module included in the software. This article is based on materials from a presentation at […]
Let me tell you about a curious situation that happened to me and how to become a contributor to a well-known project. Not long ago, I was tinkering with an idea: booting Linux directly from UEFI… This concept is not new, and there are several manuals on this topic. One of them can be found here. My long-standing attempts to resolve this issue turned into […]
In this article, I will discuss the capabilities of the Cockpit tool. Cockpit was created to simplify the administration of Linux operating systems. In short, it allows performing the most common Linux administrator tasks through a pleasant web interface. Cockpit features: installation and verification of system updates and enabling automatic updates (patching process), user management (creating, deleting, changing passwords, blocking, granting superuser rights), disk management (creating, editing LVM, […]
There is often a need to connect a USB device to a remote PC over a local network. Below, I outline my search in this direction and the path to a ready solution based on the open-source project USB/IP, describing the various obstacles encountered along the way and how to circumvent them. Part one, historical. If the machine is virtual, this is not difficult. […]
Due to changes in legislation regarding trust services ("On Electronic Trust Services" Ukraine), there arose a need for several departments in the company to work with keys located on tokens (currently, the number of hardware keys is still under discussion). As a cost-effective tool (free of charge), the choice immediately fell on usbip. The server on Ubuntu 18.04 was launched thanks to the publication "Taming […]
There is no perfect way to implement OpenStack in your company, but there are general principles that can guide you to a successful deployment. One of the advantages of open-source software like OpenStack is the ability to download it, try it out in practice, and gain hands-on experience without lengthy interactions with vendor companies or the need for long […]
Yesterday, I encountered a completely unexpected turn of events during yet another MacOS update. I generally really enjoy software updates; I always want to see the new features of various programs. When I saw this summer that I could download and install MacOS 10.15 Catalina Beta, I consciously decided against it, understanding that the beta could contain a significant amount […]
The other day in one community (VsSupport, if anyone's interested), an unprecedented drama unfolded — it turns out that knowledge from the community can be lost!!! And why is that? Because millennials (the new reincarnation of indigo children) don’t know how to maintain their own blogs, and searching on Google is difficult. From the discussion about "where the world is heading," this article was born, focusing on the beginning of work […]

At our company, "Method Lab," we often encounter questions from clients about this topic, as some independently enable a CDN. The goal of this article is to clarify what a CDN can offer in terms of […]

Preface For personal needs at home, I set up VSphere, where I run a virtual router and an Ubuntu server as a media server along with a bunch of other goodies, and this server needs to be accessible from the Internet. However, the problem is that my provider charges for static IPs, which can always be put to better use. So I used the ddclient combination + […]
The Domain Name System (DNS) is akin to a phone book, translating user-friendly names like "ussc.ru" into IP addresses. As DNS activity is present in nearly all communication sessions, regardless of protocol, DNS logging serves as a valuable data source for cybersecurity specialists, allowing them to detect anomalies or gather additional information about the research being conducted […]
