Welcome to Lesson 4. Today, we will finally 'get a feel' for Check Point. Naturally, this will be virtual. During the lesson, we will perform the following actions: Create virtual machines; Install the management server (SMS) and security gateway (SG); Familiarize ourselves with the disk partitioning process; Initialize SMS and SG; Learn about SIC; Access the Gaia Portal. Additionally, at the beginning […]
The LGA2066 platform and Skylake-X processors were introduced by Intel more than a year and a half ago. Initially, this solution was targeted at the HEDT segment, meaning high-performance systems for users engaged in content creation and processing, as Skylake-X featured a significantly greater number of processing cores compared to the typical representatives of the Kaby Lake and Coffee Lake families. However, […]
The author placed a Raspberry Pi Zero, a Bluetooth dongle, and a cable inside his new Handy Tech Active Star 40 Braille display. The built-in USB port provides power. This resulted in a self-sufficient monitorless ARM computer running Linux, equipped with a keyboard and a Braille display. It can be charged/powered via USB, including from a power bank or solar charger. Therefore, it can operate without […]
Hello, Habr. Many people who purchase a clock or a weather station have probably seen the Radio Controlled Clock or even Atomic Clock logo on the packaging. This is very convenient, as you just need to place the clock on the table, and after a while, it will automatically set itself to the correct time. Let's figure out how this works and write a decoder in Python. There are various time synchronization systems, with the most popular being […]
With the rapid development of the internet, the global community has faced data security issues. The internet is essentially an unregulated environment that offers little adherence to the laws of individual countries, creating numerous opportunities for malicious actors. Therefore, developed countries today are paying significant attention and allocating millions of dollars to enhance cybersecurity systems and immediate response to cyberattacks. However, […]
Today, CD Projekt RED held a conference regarding the results of its activities in the 2018 fiscal year. Among other things, the Polish company announced plans for mobile versions of Gwent: The Witcher Card Game. This will be available to iPhone users in the fall of 2019, and later (the date has not yet been announced) it will be the turn of Android smartphone users. "We have spent a lot of time and effort, […]
Hello, Habr! I am a contract systems administrator, or rather, an outsourcer who consults and maintains both individuals and organizations of various profiles regarding IT infrastructure. It's a tough, stressful, almost chaotic job, within which I've seen everything: from spilled vodka on laptops to serious server crashes in companies that had the budget for servers but not for brains, […]
What a loud headline, you might say. A new manufacturer of PBXs on Asterisk? Not exactly, but the equipment is quite fresh and interesting. Today, I want to tell you about the Openvox unified communications system, and it seems that the manufacturer has its own vision for unifying these very communications 🙂 The manufacturer OpenVox has been slowly but surely moving towards a fully modular structure. Initially, they made […]
Along with the release of a new driver package for its graphics cards (GeForce 419.67), NVIDIA also announced new additions to the ranks of G-Sync Compatible monitors. Additionally, the manufacturer has added new features for monitors compatible with G-Sync. The list of G-Sync Compatible monitors has been expanded with two models from ASUS. The ASUS VG278QR and VG258 displays are relatively budget-friendly gaming monitors with Full HD resolution […]
Hello everyone, this is my first experience on Habr. I want to write about non-standard methods of managing network equipment in external networks. What does non-standard mean: in most cases, to manage equipment in an external network, you need: a public IP address. Or, if the equipment is behind someone's NAT, then a public IP and a 'forwarded' port. A tunnel (PPTP/OpenVPN/L2TP+IPSec, etc.) to […]
A time series database (TSDB) in Prometheus 2 is a great example of an engineering solution that offers significant improvements compared to the v2 storage in Prometheus 1 in terms of data accumulation speed and query performance, as well as resource efficiency. We implemented Prometheus 2 in Percona Monitoring and Management (PMM), and I had the opportunity […]
This winter, specifically on one of the days between Christmas and New Year, the Veeam technical support engineers were engaged in quite unusual tasks: they were on the hunt for a group of hackers called 'Veeamonymous'. Here’s how the team devised and conducted a real-life quest at their workplace, with challenges 'similar to combat', […]
