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, […]
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 […]
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 […]
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 […]
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', […]
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 […]
In 2018, we firmly established our position – IT service management (ITSM) and IT services continue to operate despite ongoing discussions about how long they will last in this age of digital revolution. Indeed, the demand for support services is increasing – in the HDI Support and Salary Reports (Help […]
I don't know what to compare provisioning to. Maybe a cat? You can manage without it, but it's a bit better with it. Especially if it's working.)) Problem statement: I want to configure SIP phones quickly, easily, and securely. When installing a phone and especially when reconfiguring it. Many vendors have their own config formats, their own utilities for generating configs, their […]
RAID algorithms were introduced to the public back in 1987. To this day, they remain the most sought-after technology for protecting and speeding up data access in the field of information storage. However, the age of this IT technology, having crossed the 30-year mark, is more a sign of old age than maturity. The reason lies in progress, which relentlessly brings new opportunities. In times when […]
Introduction Once, management approved an experiment to implement IP telephony in our company. Since my experience in this area was minimal, the task sparked immense interest in me, and I delved into studying various aspects of the issue. Upon completing my study, I decided to share the knowledge I gained—in the hope that it will be useful to someone. So… Initial data As an IP PBX […]
In our office, we use Fanvil devices for IP telephony. Time will tell how justified the choice of cheaper Chinese products is, but I will share how I implemented the auto provisioning mechanism on Fanvil BW210P models. For those unfamiliar with this term, but somehow made it to this part, let me explain that auto provisioning is a mechanism that […]
Developers from the Italian studio RuneHeads, in collaboration with 1C Entertainment, announced the turn-based sci-fi dungeon crawler Conglomerate 451. There is no release date for the game yet, but it is known that it will be released under the Steam early access program, and this will happen 'very soon.' With the release, we can expect a tour into the cyberpunk world of the future, where corporations have gained incredible power. You […]
