  • How to set up Webmin on Ubuntu Server

    Ubuntu Server is an excellent Linux server operating system. It comes with Snaps, which makes setting up apps easier. In addition, it has live patching, so you never miss a security update and many more excellent features.

    Still, for as great as Ubuntu Server is, setting up certain things can be a pain. If you’d like to avoid the annoyances of Ubuntu Server, check out Webmin. It’s a management tool for UNIX-like operating systems. With it, users can manage their Linux systems with an elegant web UI rather than the terminal. Here’s how to set it up.

  • How to install OpenBSD 7.0 - Unixcop

    When I’ve started my migration from privative OS to Linux, after a couple of weeks my first reaction was something like: ¡let’s try them all! I mean, all the linux distributions. Spoiler alert: I couldn’t, there are too many distributions. Even in 1999 there where too many.

    After a couple of months of trying different linux flavors I’ve got a new reaction: ¡let’s try all the others OSes!. And this is why I’m showing how to install OpenBSD.

    From the OpenBSD website: «The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. As an example of the effect OpenBSD has, the popular OpenSSH software comes from OpenBSD.»

  • How to Create an SSH Honeypot to Catch Hackers in Your Linux Server - Make Tech Easier

    If you’ve ever looked at the authentication logs for your server, then you know that any server connected to the Internet is under a constant barrage of login attempts from hackers.

    Even if your server is a completely unknown hobby server, automated scripts will find it and continually try to brute force their way in using SSH. Although they’re not likely to get in as long as you’re using complex passwords or other security measures, there’s still always the chance that they could succeed.

    Luckily, there’s a useful and fun way to trap these hackers in your server and keep them too distracted to cause any trouble.

  • How To Install GoAccess on AlmaLinux 8 - idroot

    In this tutorial, we will show you how to install GoAccess on AlmaLinux 8. For those of you who didn’t know, GoAccess is an interactive and real-time web server log analyzer program that quickly analyzes and views web server logs. It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly. It parses the specified web log file and outputs the data to the terminal.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the GoAccess real-time web server log analyzer and interactive viewer on AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.

  • How To Install Drupal on Debian 11 - idroot

    In this tutorial, we will show you how to install Drupal on Debian 11. For those of you who didn’t know, Drupal is a free and open-source content management system based on the LAMP stack.

Kernel: Slowdown, CephFS, and FS-Cache / CacheFiles

  • How a performance boost in Linux kernel for one family of Intel chips slowed its latest Alder Lake processors

    The mixture of performance and efficiency CPUs in Intel’s 12th-gen Core processors, code-named Alder Lake, hasn’t just been causing problems for some Windows gamers – it almost led to complications for Linux. Phoronix’s Michael Larabel noticed a performance hit in the kernel a fortnight ago – in a work-in-progress release candidate, we should stress – and a fix for the scheduling code landed a little later. It turned out the kernel suffered on Alder Lake chips due to a performance-enhancing tweak for another Intel processor family: the multiple-Atom-core-based Jacobsville. This year, Intel officially canned its Lakefield chips. These consisted of a performance core called Sunny Cove as well as Atom-class efficiency cores dubbed Tremont. Crucially, there are still multi-Tremont-core embedded processors out there, such as Snow Ridge. These are server and infrastructure-oriented components with up to 24 cores. The first proposed cut of kernel 5.16, specifically 5.16-rc1, contained a revision to the scheduler that makes it aware that some clusters of cores share a block of L2 cache – as seen in Snow Ridge and Jacobsville.

  • Testing the Linux Kernel CephFS Client with xfstests

    I do a lot of testing with the kernel cephfs client these days, and have had a number of people ask about how I test it. For now, I’ll gloss over the cluster setup since there are other tutorials for that.

  • Major Rewrite Of Linux's FS-Cache / CacheFiles So It's Smaller & Simpler - Phoronix

    As part of David Howells of Red Hat long-term work on improving the caching code used by network file-systems, he today posted a big patch series rewriting the fscache and cachefiles code as the latest significant step on that adventure. Howells posted a set of 64 patches for rewriting the kernel's fscache and cachefiles code. Linux's fsache is a general purpose cache used by network file-systems while cachefiles is for providing a caching back-end for mounted local file-systems. The Red Hat engineer has been working on this rewrite for more than the past year.

  • The Calculator Charm: Calculatorium Leviosa! | Hackaday

    Have you ever tried waving your hand around like a magic wand and summoning a calculator? We would guess not since you’d probably look a little silly doing so. That is unless you had [Andrei’s] cool gesture-controlled calculator. [Andrei] thought it would be helpful to use a calculator in his research lab without having to take his gloves off and the results are pretty cool. His hardware consists of a PocketBeagle, an OLED, and an MPU6050 inertial measurement unit for capturing his hand motions using an accelerometer and gyroscope. The hardware is pretty straightforward, so the beauty of this project lies in its machine learning implementation.
