  • How to create Let's Encrypt SSL certificates with acme.sh on Linux

    Installing SSL certificates isn't difficult, but it's a process every Linux administrator will have to take on at some point in their career. One of the more popular methods of getting and installing SSL certificates on Linux is by way of Let's Encrypt, which is a certificate authority that offers free, automated SSL and TLS certificates. And Let's Encrypt isn't at all challenging to use.

    But there's an even easier way, one that doesn't have any dependencies or requirements. The acme.sh script is written in Shell and supports more DNS providers than other similar clients. This means you can get your SSL/TLS certificates faster and easier.

    I'm going to show you how to get and use acme.sh on Linux, so you can start working with SSL without any hassle.

  • Guide to Linux Ubuntu/Debian log files for beginners

    Updated – Ubuntu logs system events into the log files in order to help administrators maintain, analyze and diagnose system related issues and applications problems.

    Log files contain messages related to kernel, services and applications events that are kept on a centralized repository of log files under /var/log directory.

    There are various log files in Linux Ubuntu for different informations. For instance, there is a default log file dedicated to the system, another for security messages another for cron tasks. These log files are actually plain text (ASCII) written in a standardized log file format. Many of these log files are generated by the so called system log daemon, syslogd while some other applications generate their proper logs by writing to files under the directory /var/log.

    The log files generated can therefore be classified into four categories: event Logs, application Logs , system Logs and service Logs.

    In this article, we will provide an overview of Ubuntu log files, and show how to configure and use syslogd. You will also learn how log rotation works and how to view and read the log files. A brief introduction to systemd will be provided at the end .

  • Do We Still Need a Bastion?

    There is a growing discussion among network engineers, DevOps teams, and security professionals about the security benefits of bastions. Many assume that they are the “old way” of network access and have little relevance in the modern cloud native stack. These speculations are not irrelevant as in recent years, the corporate IT network perimeter as we knew it is diminishing, and the concept has been shifted to data, identity, and compute perimeter. Software-defined networking solutions have overtaken hardware firewall boxes, and the requirement of managing bare metal servers has shifted to container deployed or even serverless applications. Where do bastions fit in these scenarios? Do we even need one?

  • What’s in a package

    There is no shortage of package managers. Each tool makes its own set of tradeoffs regarding speed, ease of use, customizability, and reproducibility. Guix occupies a sweet spot, providing reproducibility by design as pioneered by Nix, package customization à la Spack from the command line, the ability to create container images without hassle, and more.

    Beyond the “feature matrix” of the tools themselves, a topic that is often overlooked is packages—or rather, what’s inside of them. Chances are that a given package may be installed using any of the many tools at your disposal. But are you really getting the same thing regardless of the tool you are using? The answer is “no”, contrary to what one might think. The author realized this very acutely while fearlessly attempting to package the PyTorch machine learning framework for Guix.

  • Emmanuele Bassi: Properties, introspection, and you

    It is a truth universally acknowledged, that a GObject class in possession of a property, must be in want of an accessor function.

    The main issue with that statement is that it’s really hard to pair the GObject property with the accessor functions that set the property’s value, and retrieve it.

    From a documentation perspective, tools might not establish any relation (gtk-doc), or they might require some additional annotation to do so (gi-docgen); but at the introspection level there’s nothing in the XML or the binary data that lets you go from a property name to a setter, or a getter, function. At least, until now.

    GObject-introspection 1.70, released alongside GLib 2.70 and GNOME 41, introduced various annotations for both properties and methods that let you go from one to the other; additionally, new API was added to libgirepository to allow bindings to dynamic languages to establish that relation at run time.

    Confidential data on notebooks, shared PCs and servers in third-party data centers require special protection – through encryption. This should be done as transparently as possible so that it does not interfere with the usual work. A Linux system completely encrypted with Cryptsetup, for example, protects the contents of the data media from outside parties, but not from other users or the system administrator. Individually encrypted home directories do this. If users log in with their login password, they simultaneously unlock the master key, which only gives access to their personal directory. If you log off again, the files are only available in encrypted form. They cannot be viewed even with root rights.

  • Linux: manage software packages with Bauh

    Package managers are a fine thing: They install all the components of an application in the correct directories, keep the components up-to-date and, if necessary, clean them from the hard drive without leaving any residue. A program can be found and installed quickly using the search function. While packages from the distribution repositories have so far dominated Linux, applications are now also reaching many Linux systems from sources other than Flatpak, Snap or AppImage. The advantages are obvious: libraries and runtime environments are included in the correct version, the programs can be updated independently of the system, are easy to set up and work on most Linux systems.

    While you can set up Snap packages with Ubuntu directly via the software management, applications in Flatpak format are available, for example, via the Flathub repository. AppImages, on the other hand, can often be found directly on the project website of an application. The package manager Bauh offers more direct access: its graphical user interface can be used to conveniently find, install, update, delete and start applications in various package formats. The name Bauh (pronounced Ba-uh) comes from the Brazilian Portuguese and means something like chest or box.

While this is useful for CNI-plugins that replaces the kube-proxy it also opens the possibility for anyone to create a proxier for a special purpose.

  • Dirk Eddelbuettel: dang 0.0.14: Several Updates

    A new release of the dang package arrived at CRAN a couple of hours ago, exactly eight months after the previous release. The dang package regroups a few functions of mine that had no other home as for example lsos() from a StackOverflow question from 2009 (!!), the overbought/oversold price band plotter from an older blog post, the market monitor from the last release as well the checkCRANStatus() function recently tweeted about by Tim Taylor. This release regroups a few small edits to several functions, adds a sample function for character encoding reading and conversion using a library already used by R (hence “look Ma, no new depends”), adds a weekday helper, and a sample usage (computing rolling min/max values) of a new simple vector class added to tidyCpp (and the function and class need to get another blog post or study …), and an experimental git sha1sum and date marker (as I am not the fan of autogenerated binaries from repos as opposed to marked released meaning: we may see different binary release with the same version number).

  • Rakudo Weekly News: 2021.42 Learning With

    Daniel Sockwell was inspired by a blog post a few weeks ago about a bouncing balls demo. The result is a new framework for learning Raku, but this time with some nice graphics: Learn Raku With: HTML Balls. Apart from the technical points, it’s also a great way (for people without much programming experience) to get involved with Raku while creating graphics and animations, rather than textual output. Check it out!

Mozilla Firefox: Spyware, Password Loggers, and Performance Monitoring

  • This Week in Glean: Designing a telemetry collection with Glean

    (“This Week in Glean” is a series of blog posts that the Glean Team at Mozilla is using to try to communicate better about our work. They could be release notes, documentation, hopes, dreams, or whatever: so long as it is inspired by Glean.) All “This Week in Glean” blog posts are listed in the TWiG index). Whenever I get a chance to write about Glean, I am usually writing about some aspects of working on Glean. This time around I’m going to turn that on its head by sharing my experience working with Glean as a consumer with metrics to collect, specifically in regards to designing a Nimbus health metrics collection. This post is about sharing what I learned from the experience and what I found to be the most important considerations when designing a telemetry collection. I’ve been helping develop Nimbus, Mozilla’s new experimentation platform, for a while now. It is one of many cross-platform tools written in Rust and it exists as part of the Mozilla Application Services collection of components. With Nimbus being used in more and more products we have a need to monitor its “health”, or how well it is performing in the wild. I took on this task of determining what we would need to measure and designing the telemetry and visualizations because I was interested in experiencing Glean from a consumer’s perspective.

  • Firefox Add-on Reviews: How to choose the right password manager browser extension

    All good password managers should, of course, effectively secure passwords; and they all basically do the same thing—you create a single, easy-to-remember master password to access your labyrinth of complex logins. Password managers not only spare you the hassle of remembering a maze of logins; they can also offer suggestions to help make your passwords even stronger. Fortunately there’s no shortage of capable password protectors out there. But with so many options, how to choose the one that’ll work best for you? Here are some of our favorite password managers. They all offer excellent password protection, but with distinct areas of strength.
