How can I Identify who SSH into my Linux System?

Filed under
Linux

Identifying who has logged into your system in Linux is way easier than the Windows Operating System.

In Linux System whenever someone tries to log in using SSH is recorded by the log file, the log file is located in /var/log/auth.log. location can be different in other distribution.

If you not found the auth.log file in your system try to execute the below command to view the log from systemctl.

journalctl -u sshd |tail -100

  • -u (Show the user journal for the current)
  • sshd (SSH user created by system by default)
  • tail -100 (Print top 100 result from log file)

journalctl of sshd
User logged in using SSH

Microsoft's Deadly Touch

Filed under
Linux

Mask of death

Everything Microsoft touched has died. Remember Nokia, Yahoo and Novell? What happened to these companies and where are they now? This is exactly what Microsoft wants to do to Linux because they don't innovate and they can't compete; so they infiltrate. Sooner or later Linux will be part of those latter companies. Something to watch out for.

Translation of the Latest 'Microsoft Loves Linux' Charm Offensive

Filed under
Linux

QUITE a few additional articles -- mostly puff pieces (below is a complete/exhaustive list) -- have been published since yesterday's blog post, which was followed by a short article from Techrights. There is a lot of Microsoft PR inside the news/media right now (more and more by the hour) and it's coordinated (sometimes in advance, based on what we learned yesterday) by Microsoft. Here is a quick rebuttal to the 4 strands of news:

  1. The Linux Foundation joins Microsoft (not a slip): Microsoft paid half a million dollars for over a hundred puff pieces (in English alone) and lots of leverage over Linux, including a distraction from the patent wars it wages.
  2. The GNU/Linux crowd gets a proprietary software database it neither wants nor needs: This might be useful when Microsoft tries to infiltrate GNU/Linux deployments like the one in Munich, later boasting better integration with Windows than with GNU/Linux (same for running Bash/Ubuntu under Windows 10).
  3. Google and .NET: Microsoft accepts that it lost the mobile wars and also lost developers, so it tries ever more desperately to spread .NET and/or Mono.
  4. Tizen/Samsung and .NET: As above.

That's about all it means. Below is the raw PR, which is intended to sometimes (it doesn't always work) mislead the reader, having misled the writers/journalists.

Related/contextual items from the news:

  1. Microsoft demonstrates its commitment to open source by joining Linux Foundation [Ed: Microsoft advocacy sites (often paid-for nonsense) like to pretend to themselves that Microsoft is now a good citizen, not racketeer. iophk: “You’ve probably seen links about LF joining Microsoft so I won’t add them. It would have been news if Microsoft joined OIN.”]
  2. Microsoft joins The Linux Foundation as a Platinum member [Ed: How MS advocacy sites put it; the larger payment (like political 'donation') was inevitable. To quote Benjamin Henrion, "Microsoft depends so much on taxing Linux via its dubious software patents that they have decided to join the Linux Foundation #corruption"]

Linux Foundation Commits Suicide as Microsoft E.E.E. Takes a Leap Forward

Filed under
Linux

I have covered Microsoft's interference with FOSS for over a decade and carefully studied even pertinent antitrust documents. I know the company's way of thinking when it comes to undermining their competition, based on internal communications and strategy papers. Even days ago we got this in the news.

The pattern of embrace and extend (to extinguish) -- all this while leveraging software patents to make Linux a Microsoft cash cow or compel OEMs to preinstall privacy-hostile Microsoft software/apps with proprietary formats (lockin) -- never ended. What I see in the Linux Foundation right now is what I saw in Nokia 5 years ago and in Novell 10 years ago -- the very thing that motivated me to start Boycott Novell, a site that has just turned 10 with nearly 22,000 blog posts.

It is a saddening day because it's a culmination, after years of Microsoft 'micro' payments to the Linux Foundation (e.g. event sponsorship in exchange for keynote positions), which will have Microsoft shoved down the throats of GNU/Linux proponents and give an illusion of peace when there is none, not just on the patent front but also other fronts (see what Microsoft's partner Accenture is doing in Munich right now). The links below are a complete list of the bad (in my view very bad) news.

"We need to slaughter Novell before they get stronger….If you’re going to kill someone, there isn’t much reason to get all worked up about it and angry. You just pull the trigger. Any discussions beforehand are a waste of time. We need to smile at Novell while we pull the trigger."

  • Robert O'Callahan: Visualizing Control Flow In Pernosco

    In traditional debuggers, developers often single-step through the execution of a function to discover its control flow. One of Pernosco's main themes is avoiding single-stepping by visualizing state over time "all at once". Therefore, presenting control flow through a function "at a glance" is an important Pernosco feature and we've recently made significant improvements in this area. This is a surprisingly hard problem. Pernosco records control flow at the instruction level. Compiler-generated debuginfo maps instructions to source lines, but lacks other potentially useful information such as the static control flow graph. We think developers want to understand control flow in the context of their source code (so approaches taken by, e.g., reverse engineering tools are not optimal for Pernosco). However, mapping potentially complex control flow onto the simple top-to-bottom source code view is inherently lossy or confusing or both. For functions without loops there is a simple, obvious and good solution: highlight the lines executed, and let the user jump in time to that line's execution when clicked on. In the example below, we can see immediately where the function took an early exit.

  • Marco Castelluccio: On code coverage and regressions

    There are two schools of thought when it comes to code coverage: those who think it is a useless metric and those who think the opposite (OK, I’m a bit exaggerating, there are people in the middle…). I belong to the second “school”: I have always thought, intuitively, that patches without tests are more likely to cause postrelease regressions, and so having test coverage decreases risk. A few days ago, I set out to confirm this intuition, and I found this interesting study: Code Coverage and Postrelease Defects: A Large-Scale Study on Open Source Projects. The authors showed (on projects that are very different from Firefox, but still…) that there was no correlation between project coverage and the amount of bugs that are introduced in the project and, more importantly, there was no correlation between file coverage and the amount of bugs that are introduced in the file.

Nvidia GPU Passthrough To Windows VM From Linux Host

Nvidia has now officially enabled GPU passthrough support for Windows virtual machines on GeForce graphics cards. In other words, this effectively means it?s possible to run a Linux machine and then run a virtual Windows machine within it, and hand that unfettered access to a graphics card. This is a big win for those wanting to run Windows games from within a virtual machine on your Linux desktop. They will be able to play Windows-based games using a virtual machine with GPU passthrough enabled. Read more

  • A brief intro to Red Hat OpenShift for Node.js developers – IBM Developer

    Container-based deployment models are the modern way to develop and deliver your applications. The most common tool for building with containers is Kubernetes, an open-source container-orchestration system for automating computer application deployment, scaling, and management. Kubernetes has helped usher in a standardized way to deploy and manage applications at scale, but it can be a sprawling, difficult beast to manage when your application becomes more mature and more complex. A company will need to have a robust DevOps team to manage a full-fledged Kubernetes-based production system. [...] My colleague, JJ Asghar summed it up nicely: “OpenShift provides creature comforts to talk to the Kubernetes “API”—at the same level of robustness—as long as you’re willing to use the opinions OpenShift brings.” The good news? Those opinions are tried and tested, enterprise-ready choices with the backing and support of Red Hat. So, what do Node.js developers need to know about OpenShift deployment? This blog post covers the “what” and “how” of deploying your Node.js application in an OpenShift environment.

  • How Red Hat data scientists use and contribute to Open Data Hub

    Artificial intelligence (AI) and machine learning (ML) drive much of the world around us, from the apps on our phones to electric cars on the highway. Allowing such things to run as accurately as possible takes huge amounts of data to be collected and understood. At the helm of that critical information are data scientists. So, what’s a day on the job look like for data scientists at Red Hat? Don Chesworth, Principal Data Scientist, gives you a glimpse into his day-to-day in a short video (aptly named "A Day in the Life of a Red Hat Data Scientist") that’s now available on our website. Isabel Zimmerman, Data Science Intern, provides a look at some of the tools she uses on the job in "Using Open Data Hub as a Red Hat Data Scientist." We’ll cover some of the highlights in this post.
