Software

SNMP monitoring is by far the most common type of network monitoring technology. It allows administrators of networks of any size to be kept informed of the status of the networks they manage as well as their utilization. Likewise, Linus is also a very common platform that many network administrators have turned to. Although it is not yet as common in the desktop world as the commercial offerings from some mega-vendors, it is very common in the server world. Even IBM has made it its OS of choice on many of its higher-range systems.

Kali Linux team has renamed their meta-packages to more meaningful to understand it in a better way.

This implementation will optimize Kali, reduce ISO size, and organize meta-packages in a better way.

Some of you may already know about it, however, i will give you an overview about meta-package before discuss further on this topic.

What’s Meta-package?

Meta-packages are specialized packages, they do not contain any files usually found in packages.

Meta-package is a way to collect and group related software packages, they simply depend on other packages to be installed.

It allows entire sets of software to be installed by selecting only the appropriate meta-package.

Say for example, Each Linux desktop environments comes with a wide range of applications, it can be installed by running a single command because they were already grouped together.

This will reduce download requirements, i mean to say, this will obtain all the Gnome packages in one download.

  • Ampere Computing Is Keeping Close Track Of The Linux Performance For Their ARM Servers

    Hardware vendor Ampere Computing with their impressive ARM servers is doing a great job on closely following their hardware's Linux performance as part of a rigorous continuous testing regiment or ensuring quality, compatibility, and stability while being fully-automated.

    Ampere Computing's Travis Lazar talked at this week's Linux Foundation events in San Diego over the importance of continuous regression testing for software and hardware development by talking about their internal workflow and software in place. Their internal system is the "Totally Automated Regression System" or TARS for short. TARS makes use of various open-source components including the Phoronix Test Suite and its vast collection of benchmarks for providing comprehensive test coverage plus Ampere's own "extensions" to the Phoronix Test Suite. TARS also incorporates the provisioning/configuration responsibilities as well as analysis of the data.

  • From ProdOps to DevOps: Surviving and thriving

    For many of us in Production Operations (ProdOps), change is the enemy. If something changes, there is now an opportunity for things that were working just fine to experience problems. It is like a game of Jenga. When will the tower fall because a seemingly minor change unbalances the whole stack of pieces? ProdOps teams hate change so much, that countless frameworks have been invented to "manage" changes; in reality, these frameworks make the procedure for effecting a change so onerous that most people give up and accept the status quo.

    Actually, that statement is a bit unfair. These frameworks are an attempt to wrap planning and consensus around production changes, thus minimizing potential downtime caused by random or rogue changes (see Why the lone wolf mentality is a sysadmin mistake).

6 Best Log Management Tools For Linux in 2019

Filed under
Server
Software

Before we can talk about log management, let’s define what a log is. Simply defined, a log is the automatically-produced and time-stamped documentation of an event relevant to a particular system. In other words, whenever an event takes place on a system, a log is generated. Systems and devices will generate logs for different types of events and many systems give administrators some degree of control over which event generates a log and which doesn’t.

As for log management, It is simply referring to the processes and policies used to administer and facilitate the generation, transmission, analysis, storage, archiving and eventual disposal of large volumes of log data. Although not clearly stated, log management implies a centralized system where logs from multiple sources are collected. Log management is not just log collection, though. It is the management part which is the most important. And log management systems often have multiple functionalities, collecting logs being just one of them.

Once logs are received by the log management system, they need to be standardized into a common format as different systems format logs differently and include different data. Some start a log with the date and time, some start it with an event number. Some only include an event ID while others include a full-text description of the event. One of the purposes of log management systems is to ensure that all collected log entries are stored in a uniform format. This will event correlation and eventual searching much easier down the line.

Even correlation and searching are two additional major functions of several log management systems. The best of them feature a powerful search engine that allows administrators to zero-in on precisely what they need. Correlation functions will automatically group related events, even if they are from different sources. How—and how successfully—different log management system accomplish that is a major differentiating factor.

Replicating Particle Collisions at CERN with Kubeflow

This is where Kubeflow comes in. They started by training their 3DGAN on an on-prem OpenStack cluster with 4 GPUs. To verify that they were not introducing overhead by using Kubeflow, they ran training first with native containers, then on Kubernetes, and finally on Kubeflow using the MPI operator. They then moved to an Exoscale cluster with 32 GPUs and ran the same experiments, recording only negligible performance overhead. This was enough to convince them that they had discovered a flexible, versatile means of deploying their models to a wide variety of physical environments.

Beyond the portability that they gained from Kubeflow, they were especially pleased with how straightforward it was to run their code. As part of the infrastructure team, Ricardo plugged Sofia’s existing Docker image into Kubeflow’s MPI operator. Ricardo gave Sofia all the credit for building a scalable model, whereas Sofia credited Ricardo for scaling her team’s model. Thanks to components like the MPI operator, Sofia’s team can focus on building better models and Ricardo can empower other physicists to scale their own models.

  • What salary can a sysadmin expect to earn?

    The path to reliable salary data sometimes is sometimes paved with frustration. That’s because the honest answer to a reasonable question—what should I be paid for this job?—is usually: "It depends."

    Location, experience, skill set, industry, and other factors all impact someone’s actual compensation. For example, there’s rarely a single, agreed-upon salary for a particular job title or role.

    All of the above applies to system administrators. It’s a common, long-established IT job that spans many industries, company sizes, and other variables. While sysadmins may share some common fundamentals, it’s certainly not a one-size-fits-all position, and it’s all the truer as some sysadmin roles evolve to take on cloud, DevOps, and other responsibilities.

    What salary can you expect to earn as a sysadmin? Yeah, it depends. However, that doesn’t mean you can’t get a clear picture of what sysadmin compensation looks like, including specific numbers. This is information worth having handy if you’re a sysadmin on the job market or seeking a promotion.

    Let’s start with some good news from a compensation standpoint. Sysadmins—like other IT pros these days—are in demand.

    "In today’s business environment, companies are innovating and moving faster than ever before, and they need systems that can keep up with the pace of their projects and communications, as well as help everything run smoothly," says Robert Sutton, district president for the recruiting firm Robert Half Technology. "That’s why systems administrators are among the IT professionals who can expect to see a growing salary over the next year or so."

  • Run Mixed IT Efficiently, The Adient – SUSE Way.

    When you have multiple distributions, such as Red Hat and SUSE, you can reduce administration complexity and save administration time and resources with a common management tool. Adient had applications running on both SUSE Linux Enterprise Server and Red Hat Enterprise Linux. Adient deployed SUSE Manager to manage their Mixed IT environment involving both distributions.

  • Package Management Domain Model

    When I wrote this model, we were trying to unify a few different sorts of packages. Coming from SpaceWalk, part of the team was used to wokring on RPMS with the RPM Database for storage, and Yum as the mechanism for fetching them. The other part of the team was coming from the JBoss side, working with JAR, WAR, EAR and associated files, and the Ivy or Maven building and fetching the files.

    We were working within the context of the Red Hat Network (as it was then called) for delivering content to subscribers. Thus, we had the concept of Errata, Channels, and Entitlements which are somewhat different from what other organizations call these things, but the concepts should be general enough to cover a range of systems.

    There are many gaps in this diagram. It does not discuss the building of packages, nor the relationship between source and binary packages. It also does not provide a way to distinguish between the package storage system and the package fetch mechanism.

    But the bones are solid. I’ve used this diagram for a few years, and it is useful.

  • The Apache® Software Foundation Announces Annual Report for 2019 Fiscal Year

    The Apache® Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, announced today the availability of the annual report for its 2019 fiscal year, which ended 30 April 2019.

  • Open Source at the ASF: A Year in Numbers

    332 active projects, 71 million lines of code changed, 7,000+ committers…

    The Apache Software Foundation has published its annual report for fiscal 2019. The hub of a sprawling, influential open source community, the ASF remains in rude good health, despite challenges this year including the need for “an outsized amount of effort” dealing with trademark infringements, and “some in the tech industry trying to exploit the goodwill earned by the larger Open Source community.”

    [...]

    The ASF names 10 “platinum” sponsors: AWS, Cloudera, Comcast, Facebook, Google, LeaseWeb, Microsoft, the Pineapple Fund, Tencent Cloud, and Verizon Media

  • Apache Software Foundation Is Worth $20 Billion

    Yes, Apache is worth $20 billion by its own valuation of the software it offers for free. But what price can you realistically put on open source code?

    If you only know the name Apache in connection with the web server then you are missing out on some interesting software. The Apache Software Foundation ASF, grew out of the Apache HTTP Server project in 1999 with the aim of furthering open source software. It provides a licence, the Apache licence, a decentralized governance and requires projects to be licensed to the ASF so that it can protect the intellectual property rights.

  • Apache Security Advisories Red Flag Wrong Versions in Patching Gaffe

    Researchers have pinpointed errors in two dozen Apache Struts security advisories, which warn users of vulnerabilities in the popular open-source web app development framework. They say that the security advisories listed incorrect versions impacted by the vulnerabilities.

    The concern from this research is that security administrators in companies using the actual impacted versions would incorrectly think that their versions weren’t affected – and would thus refrain from applying patches, said researchers with Synopsys who made the discovery, Thursday.

    “The real question here from this research is whether there remain unpatched versions of the newly disclosed versions in production scenarios,” Tim Mackey, principal security strategist for the Cybersecurity Research Center at Synopsys, told Threatpost. “In all cases, the Struts community had already issued patches for the vulnerabilities so the patches exist, it’s just a question of applying them.”

Slimbook Tease New Linux Laptop in Apple-Bashing Video

The video, which should be embedded above, is relatively short and relatively bizarre. It follows a Slimbook engineer in a penguin mask carefully measuring an apple before getting up and smashing it with a baseball bat bearing the Slimbook brand name. Accompanying the clip are the hashtags #NoMoreFruit and #ForgetTheFruit — a playful dig at a certain fruit-branded company whose laptops are fairly popular? I think so. The video also reveals that Slimbook will announce its new device on November 21, 2019 via the Slimbook website. Read more
