An article about working with Junos PyEZ — a Python microframework that enables you to manage and automate devices running Junos OS — automation and management, all as we like it. The script written in this article aimed at several goals: learning Python and automating tasks for gathering information or changing configurations on equipment running Junos OS. The choice […]
Hello, Habr users. Today, classes will start in the first group of the 'PostgreSQL' course. In this regard, we would like to tell you about how the open webinar for this course went. In another open lesson, we discussed the challenges SQL databases face in the era of clouds and Kubernetes. Additionally, we examined how SQL databases adapt and mutate under the influence of […]
The Hyperbola project, which is listed among the fully free distributions supported by the Free Software Foundation, has published a plan to transition to using the kernel and user utilities from OpenBSD while porting some components from other BSD systems. The new distribution is planned to be released under the name HyperbolaBSD. HyperbolaBSD is intended to be developed as a full fork of OpenBSD, which will be expanded with new code provided under GPLv3 and LGPLv3 licenses. The ongoing development […]
Security researchers from the Chinese company Tencent have presented a new variant of the Magellan vulnerability (CVE-2019-13734), which allows for code execution when processing SQL constructs formatted in a specific way in the SQLite database. A similar vulnerability was published by the same researchers a year ago. The vulnerability is notable as it enables remote attacks on the Chrome browser and permits control over the user's system when opening web pages controlled by the attacker. […]
A release of the lightweight Live distribution AntiX 19.1 has been published, built on a Debian package base and aimed at installation on outdated hardware. The release is based on Debian 10 (Buster) but comes without the system manager systemd and uses eudev instead of udev. The default user environment is formed using the IceWM window manager, though fluxbox, jwm, and other alternatives are also offered […]
In the end, as always, there is a brief summary. Do you remember the story about a guy? He recently came over and told a funny story. I think you’ll find it interesting. It’s not about the story itself, but about how, well, these things happen. I reflected on my own experiences and spotted several similar situations. Back in the mid-2000s […]
Last time, we began telling the story of DNS — recalling how the project started and what problems it was meant to solve in the ARPANET. Today, we will talk about the first DNS server, BIND. Photo — John Markos O’Neill — CC BY-SA The First DNS Servers After Paul Mockapetris and Jon Postel proposed the concept of domain names in 1983, […]
There are many articles about Jenkins on Habr, but few describe examples of working with Jenkins and Docker agents. All popular project build tools like Drone.io, Bitbucket Pipeline, GitLab, GitHub Actions, and others can build everything in containers. But what about Jenkins? Today, there is a solution to the problem: Jenkins 2 works wonderfully with Docker agents. In this article […]
Clearly, embarking on the development of a new communication standard without considering security mechanisms is extraordinarily questionable and pointless. The security architecture of 5G is a set of security mechanisms and procedures implemented in fifth-generation networks, encompassing all network components from the core to radio interfaces. Fifth-generation networks are essentially an evolution of fourth-generation networks […]
The latest version of Windows 10, numbered 1909, has a problem that dates back to the days of Windows XP. The issue is that the context menu of some programs, such as the Pidgin messenger, gets partially obscured by the taskbar. As a result, some options are inaccessible. It is noted that the problem was fixed in the Windows 10 April 2018 Update, but it persists in the current version of Windows 10 […]
The release of the new stable branch of the network analyzer Wireshark 3.2 has taken place. Recall that the project was initially developed under the name Ethereal, but in 2006, due to a conflict with the trademark owner of Ethereal, the developers were forced to rename the project to Wireshark. Key innovations in Wireshark 3.2.0: Support for stream mode packet reassembly has been implemented for HTTP/2. Support for importing profiles from zip archives has been added […]
This is a true story; I witnessed it with my own eyes. A few years ago, a guy, like many of you, worked as a programmer. Just to clarify, he was a 1C specialist, working at a manufacturing company. Prior to that, he had tried various jobs – four years as a programmer in a franchise, a project manager, managing to complete 200 hours while simultaneously earning a percentage […]
